Board Certified Specialist in Sports Dietetics (CSSD) Exam — Questions and Answers

Question 1: A strength athlete wants to maximize muscle protein synthesis post-workout. Which leucine threshold must typically be met per meal to optimally stimulate MPS?

5.0-6.0g leucine
0.5-1.0g leucine
1.5-2.0g leucine (Correct answer)
3.0-4.0g leucine

Correct answer: 1.5-2.0g leucine

Approximately 1.7-2.0g of leucine per meal is generally required to reach the leucine threshold and maximally stimulate muscle protein synthesis.

Question 2: In the context of pre-exercise nutrition, why is a low-glycemic index meal preferred 3–4 hours before competition compared to a high-GI meal?

It sustains blood glucose and avoids pre-exercise hyperinsulinemia (Correct answer)
It delays gastric emptying to prevent GI issues
It provides more total calories
It increases fat availability for aerobic metabolism

Correct answer: It sustains blood glucose and avoids pre-exercise hyperinsulinemia

A low-GI pre-exercise meal maintains steady blood glucose without an insulin spike that could suppress fat mobilization and cause rebound hypoglycemia at exercise onset.

Question 3: Creatine supplementation is least likely to benefit performance in which competition scenario?

A 5 km cross-country run requiring sustained aerobic output (Correct answer)
Repeated 10-second sprint intervals in a speed skating race
100 m freestyle swimming with multiple heats
Power-clean maximal efforts in weightlifting

Correct answer: A 5 km cross-country run requiring sustained aerobic output

Creatine enhances phosphocreatine resynthesis for short, explosive efforts but provides minimal benefit for continuous aerobic endurance events like a 5 km run.

Question 4: Which assessment method provides the MOST accurate measurement of total body water (TBW) in an athlete, serving as the gold standard?

Air displacement plethysmography
Deuterium dilution (isotope dilution technique) (Correct answer)
Skinfold caliper assessment
Bioelectrical impedance analysis

Correct answer: Deuterium dilution (isotope dilution technique)

Deuterium (²H₂O) dilution is the gold-standard method for quantifying TBW by measuring isotope distribution in body fluids.

Question 5: Which variable most strongly confounds BIA measurements taken in an athletic population?

Ambient room temperature during testing
Hydration status of the athlete (Correct answer)
The brand of BIA device used
Time of day the test is administered

Correct answer: Hydration status of the athlete

BIA relies on fluid distribution to estimate lean mass; dehydration or hyperhydration significantly alters electrical conductance and produces inaccurate body fat estimates.

Question 6: Which carbohydrate form is most evidence-supported for intra-exercise use when solid food consumption is impractical?

Protein bars with embedded carbohydrates
Energy chews with 25g carbohydrate per serving
Sports gels delivering 20–25g of mixed carbohydrates per sachet with water (Correct answer)
Dried fruit alone providing 30g carbohydrate

Correct answer: Sports gels delivering 20–25g of mixed carbohydrates per sachet with water

Sports gels providing 20–25g of carbohydrate (typically glucose + fructose blend) consumed with water are the most studied, portable, and tolerated intra-exercise carbohydrate form.

Question 7: A strength athlete is using creatine monohydrate. How does creatine supplementation most directly support recovery from resistance exercise?

Enhances cortisol clearance to reduce muscle catabolism
Increases glycogen storage capacity by 50%
Directly increases muscle protein synthesis by activating mTOR
Replenishes phosphocreatine stores and may enhance glycogen synthesis when co-ingested with carbohydrate (Correct answer)

Correct answer: Replenishes phosphocreatine stores and may enhance glycogen synthesis when co-ingested with carbohydrate

Creatine replenishes PCr for subsequent high-intensity bouts and may augment glycogen synthesis when combined with carbohydrate, supporting recovery between resistance training sets and sessions.

Question 8: The thermic effect of food (TEF) contributes approximately what percentage of total daily energy expenditure in most individuals?

25–30%
5–10% (Correct answer)
1–3%
15–20%

Correct answer: 5–10%

TEF accounts for approximately 5–10% of total daily energy expenditure, representing the energy cost of digesting, absorbing, and metabolizing food.

Question 9: An athlete recovering from an eating disorder wants to improve body composition. The CSSD's PRIMARY role should be to:

Collaborate with the multidisciplinary treatment team and focus on health-supportive eating behaviors (Correct answer)
Design an aggressive deficit to reach goal weight quickly
Provide a high-protein diet plan independently
Recommend body composition testing monthly to track progress

Correct answer: Collaborate with the multidisciplinary treatment team and focus on health-supportive eating behaviors

Athletes with eating disorder histories require coordinated care; the CSSD works within a multidisciplinary team and avoids approaches that reinforce diet culture.

Question 10: Bioelectrical impedance analysis (BIA) estimates body composition primarily by measuring:

The resistance of body tissues to a low-level electrical current (Correct answer)
The volume of air displaced when an athlete sits in a sealed chamber
The absorption of two X-ray energy beams by different tissues
The difference between body weight in air and underwater

Correct answer: The resistance of body tissues to a low-level electrical current

BIA passes a small electrical current through the body and measures impedance (resistance + reactance); fat-free mass, which contains more water and electrolytes, conducts electricity better than fat mass.

Question 11: How does the CSSD body of knowledge relate to daily professional practice?

It only applies during certification exams
It provides the foundational framework that guides decision-making and standard practices (Correct answer)
It is relevant only for academic research
It is theoretical and has limited practical application

Correct answer: It provides the foundational framework that guides decision-making and standard practices

The body of knowledge provides the foundational framework of principles, standards, and best practices that professionals use to guide their daily decision-making, ensure consistent quality, and maintain alignment with industry standards.

Question 12: A combat sport athlete wants to lose 5 kg in 2 weeks before a weigh-in. The dietitian's MOST appropriate response is to:

Help the athlete use fluid restriction and saunas to achieve the weight cut efficiently
Prescribe a severe caloric restriction diet to achieve the 5 kg goal safely
Educate the athlete on the performance and health risks of rapid weight cutting and discuss gradual pre-season weight management (Correct answer)
Decline to provide any guidance and refer to the team physician only

Correct answer: Educate the athlete on the performance and health risks of rapid weight cutting and discuss gradual pre-season weight management

The CSSD's ethical role includes educating athletes about the dangers of acute weight cutting while supporting safer long-term weight management strategies.

Question 13: Which DXA measurement output is MOST directly used to diagnose osteoporosis according to the WHO T-score criteria?

T-score at the lumbar spine or femoral neck (Correct answer)
Z-score at the total hip
Lean mass in kilograms
Bone mineral content in grams

Correct answer: T-score at the lumbar spine or femoral neck

The WHO defines osteoporosis as a T-score ≤ -2.5 SD at the lumbar spine or femoral neck compared to a young adult reference population.

Question 14: An endurance cyclist is training in 35°C heat for 3 hours. Which electrolyte replacement strategy is most appropriate?

Potassium supplements taken pre-exercise
Hypertonic sports drink consumed only at the finish
Sodium-containing beverage (500–700 mg/L) consumed regularly (Correct answer)
Water only to avoid GI distress

Correct answer: Sodium-containing beverage (500–700 mg/L) consumed regularly

Sodium-containing fluids help replace sweat sodium losses, maintain plasma osmolality, and stimulate thirst during prolonged exercise in heat.

Question 15: A 50-year-old masters swimmer reports difficulty maintaining weight compared to when she was younger. The CSSD should attribute this PRIMARILY to:

Reduced absorption of macronutrients in the gut
Age-related decline in RMR, reduced muscle mass (sarcopenia), and decreased NEAT (Correct answer)
Menopause-related increase in appetite hormones only
A psychological shift in food preference with age

Correct answer: Age-related decline in RMR, reduced muscle mass (sarcopenia), and decreased NEAT

Aging reduces resting metabolic rate through sarcopenia and decreased NEAT, making weight maintenance harder without corresponding reductions in energy intake.

Question 16: What counseling strategy involves setting small, achievable goals?

Behavior therapy
Exposure therapy
SMART goals (Correct answer)
Motivational enhancement

Correct answer: SMART goals

SMART goals are a well-known framework for goal setting, where 'A' stands for Achievable and 'R' for Realistic. This method specifically emphasizes breaking down larger objectives into smaller, manageable steps to increase the likelihood of success and client adherence. By setting goals that are Specific, Measurable, Achievable, Relevant, and Time-bound, clients can build confidence and progressively work towards their overall objectives.

Question 17: A CSSD working with a marathon runner recommends 'carbohydrate periodization.' Which statement best describes this approach?

Eating only carbohydrates on hard training days and avoiding them on rest days
Strategically manipulating carbohydrate availability across training sessions to promote both metabolic adaptation and fueled performance (Correct answer)
Consuming the same carbohydrate amount daily regardless of training load
Eliminating carbohydrates entirely during base-building phases

Correct answer: Strategically manipulating carbohydrate availability across training sessions to promote both metabolic adaptation and fueled performance

Carbohydrate periodization intentionally varies carbohydrate intake around training to enhance fat oxidation adaptations on low-carb sessions while fully fueling key performance sessions.

Question 18: A triathlete asks about beta-alanine use for competition. Which competition format would yield the greatest ergogenic benefit?

Track cycling sprint event (under 15 seconds)
Olympic distance triathlon (1.5–2.5 hours)
Ironman triathlon (8–17 hours)
Sprint triathlon (under 60 minutes) with high-intensity segments (Correct answer)

Correct answer: Sprint triathlon (under 60 minutes) with high-intensity segments

Beta-alanine increases muscle carnosine, which buffers hydrogen ions during high-intensity exercise lasting 1–4 minutes, most relevant to sprint-distance triathlon.

Question 19: A wrestler needs to lose 3 kg in 5 days before weigh-in. The CSSD should PRIMARILY counsel against this practice because:

It will permanently lower the athlete's set point
Rapid weight cutting impairs strength, endurance, and cognitive performance (Correct answer)
Carbohydrate depletion alone is sufficient risk
It is prohibited by governing bodies

Correct answer: Rapid weight cutting impairs strength, endurance, and cognitive performance

Rapid weight cutting causes measurable decrements in strength, aerobic capacity, and decision-making ability that persist through competition.

Question 20: How does the CSSD body of knowledge relate to daily professional practice?

It only applies during certification exams
It is relevant only for academic research
It is theoretical and has limited practical application
It provides the foundational framework that guides decision-making and standard practices (Correct answer)

Correct answer: It provides the foundational framework that guides decision-making and standard practices

Question 21: Beta-alanine supplementation improves performance primarily by increasing intramuscular concentrations of which buffer?

Glutamine
Phosphocreatine
Bicarbonate
Carnosine (Correct answer)

Correct answer: Carnosine

Beta-alanine is the rate-limiting precursor to carnosine synthesis; increased carnosine acts as an intramuscular pH buffer, delaying fatigue during high-intensity exercise.

Question 22: What is the recommended timing for a pre-exercise hydration protocol according to ACSM guidelines?

Consume 5–7 mL/kg body weight at least 4 hours before exercise (Correct answer)
Drink 500 mL immediately before exercise begins
Drink 1 L 30 minutes before exercise to maximize plasma volume
Avoid fluids 2 hours pre-exercise to prevent GI distress

Correct answer: Consume 5–7 mL/kg body weight at least 4 hours before exercise

ACSM recommends 5–7 mL/kg at least 4 hours before exercise, allowing time for renal excretion of excess fluid and achieving euhydration without GI discomfort.

Question 23: When counseling an athlete from a collectivist cultural background, which counseling adaptation is MOST important?

Focus exclusively on individual performance metrics
Emphasize personal autonomy and self-reliance
Provide a standard meal plan without cultural modification
Involve family or community members in the nutrition planning process (Correct answer)

Correct answer: Involve family or community members in the nutrition planning process

In collectivist cultures, food decisions are often family- or community-centered, so including key social members improves adherence and relevance.

Question 24: Which concept explains why athletes performing concurrent training (strength + endurance) may see blunted strength gains compared to strength training alone?

Substrate competition between fat and glucose during resistance exercise
Excessive protein intake during concurrent training
AMPK-mTOR interference, where AMPK activated by endurance work suppresses mTORC1-driven hypertrophy signaling (Correct answer)
Greater EPOC suppressing testosterone release

Correct answer: AMPK-mTOR interference, where AMPK activated by endurance work suppresses mTORC1-driven hypertrophy signaling

Endurance exercise activates AMPK, which can phosphorylate and inhibit mTORC1, the primary anabolic signaling hub for muscle protein synthesis and hypertrophy.

Question 25: An athlete asks about phosphatidylserine (PS) as an ergogenic aid. Which physiological mechanism is most associated with its proposed benefits in sport?

Enhancing gastrointestinal absorption of dietary protein
Directly stimulating muscle protein synthesis
Attenuating exercise-induced cortisol rise and supporting cognitive recovery (Correct answer)
Increasing maximal aerobic power output

Correct answer: Attenuating exercise-induced cortisol rise and supporting cognitive recovery

Phosphatidylserine has been shown to attenuate the cortisol response to exercise stress and may support cognitive function during and after intense training.

Question 26: An athlete wants to cut weight for competition. Which method is MOST evidence-based for preserving lean mass during a caloric deficit?

Intermittent fasting with no protein timing strategy
Rapid weight loss of >1.5% body weight per week
Severe carbohydrate restriction below 50 g/day
Slow deficit of 300–500 kcal/day with high protein intake (~1.8–2.4 g/kg) (Correct answer)

Correct answer: Slow deficit of 300–500 kcal/day with high protein intake (~1.8–2.4 g/kg)

A modest caloric deficit combined with high protein intake best preserves lean mass during weight loss in athletes.

Question 27: Which professional attribute is most valued in hydration strategies within the CSSD field?

Collaboration leverages diverse perspectives and combined expertise to achieve better outcomes than any individual could alone.

Question 29: Which dietary strategy has the STRONGEST evidence for reducing appetite while preserving muscle mass during weight loss in athletes?

Meal replacement shakes as the sole food source
High dietary fiber and high protein intake (≥1.6 g/kg/day) (Correct answer)
Low-fat diet with moderate protein (~0.8 g/kg/day)
Very low-carbohydrate ketogenic diet

Correct answer: High dietary fiber and high protein intake (≥1.6 g/kg/day)

High protein intake combined with dietary fiber promotes satiety and protects lean mass during caloric restriction, supported by strong evidence.

Question 30: Which behavior is consistent with client-centered counseling?

Encouraging client autonomy (Correct answer)
Giving strict instructions
Judging client food choices
Focusing only on lab results

Correct answer: Encouraging client autonomy

Client-centered counseling, also known as person-centered therapy, is founded on the principle of empowering the client. It emphasizes that individuals have the inherent capacity for self-direction and growth. Therefore, a key behavior of a client-centered counselor is to encourage and respect the client's autonomy, allowing them to make their own choices and take responsibility for their health journey rather than imposing instructions.

Question 31: When calculating an athlete's target weight for a lower weight class, which approach is MOST appropriate?

Estimate based on the athlete's self-reported desired weight
Subtract 10% from current body weight regardless of composition
Use BMI to determine the lowest healthy weight class
Determine minimum competition weight based on minimum body fat thresholds and fat-free mass (Correct answer)

Correct answer: Determine minimum competition weight based on minimum body fat thresholds and fat-free mass

Minimum competition weight is calculated using current fat-free mass and established minimum body fat thresholds to avoid unsafe weight cutting.

Question 32: A basketball player is cutting weight for the season and asks about using a fat burner supplement. The CSSD should PRIMARILY advise:

Fat burners are effective and safe when used as directed
Caffeine-based fat burners are approved by all sports governing bodies
Supplements are unnecessary but not harmful
Most fat burner supplements lack efficacy evidence and carry risk of banned substance contamination (Correct answer)

Correct answer: Most fat burner supplements lack efficacy evidence and carry risk of banned substance contamination

Most fat burner supplements are not supported by strong evidence, and many carry risks including contamination with prohibited substances detected in third-party testing.

Question 33: What role does collaboration play in hydration strategies for CSSD professionals?

It slows down work unnecessarily
It reduces individual accountability
It is only needed in emergencies
It enhances outcomes through diverse perspectives and shared expertise (Correct answer)

Question 34: When interpreting a dietary recall from an athlete who is vegetarian, which nutrient requires the MOST careful assessment for adequacy?

Vitamin B12 (Correct answer)
Vitamin C
Folate
Potassium

Correct answer: Vitamin B12

Vitamin B12 is found almost exclusively in animal products, making it the primary nutrient of concern for athletes following vegetarian or vegan diets.

Question 35: Compared to water, what advantage does low-fat chocolate milk offer for post-exercise rehydration?

Lower osmolality than most sports drinks
Faster gastric emptying due to its liquid composition
Combined protein, carbohydrate, sodium, and fluid promote rehydration and muscle repair simultaneously (Correct answer)
Lower caloric density, reducing weight gain

Correct answer: Combined protein, carbohydrate, sodium, and fluid promote rehydration and muscle repair simultaneously

Chocolate milk provides carbohydrate for glycogen resynthesis, protein for muscle repair, and sodium/fluid for rehydration, making it a multi-purpose recovery beverage.

Question 36: Which personal protective equipment (PPE) principle applies to ALL CSSD certified professionals regardless of their specific role?

PPE must be properly fitted, maintained, and replaced as needed (Correct answer)
Any PPE will provide adequate protection
PPE is only necessary during formal inspections
PPE is optional if experienced in the field

Correct answer: PPE must be properly fitted, maintained, and replaced as needed

Regardless of experience level or specific role, PPE must be properly fitted to the individual, regularly maintained in good condition, and replaced when worn or damaged. Improperly fitted or degraded PPE can provide a false sense of security.

Question 37: What is motivational interviewing primarily used for?

Encouraging dietary behavior change (Correct answer)
Diagnosing diseases
Conducting fitness tests
Prescribing medication

Correct answer: Encouraging dietary behavior change

Motivational interviewing is a client-centered counseling approach specifically designed to help individuals explore and resolve ambivalence about behavior change. In sports dietetics, it is used to encourage athletes to adopt healthier dietary habits or adhere to specific nutrition plans by eliciting their own motivations and commitment to change. This approach fosters autonomy and self-efficacy in achieving nutrition goals.

Question 38: Which skill is most critical for effective weight management?

Technical expertise alone
Communication and stakeholder engagement (Correct answer)
Individual work preferences
Speed of decision-making

Correct answer: Communication and stakeholder engagement

1.030 or higher
1.020–1.024
1.001–1.020 (Correct answer)
1.025–1.029

Correct answer: 1.001–1.020

A USG of 1.001–1.020 indicates euhydration, while values above 1.020 suggest significant dehydration.

Question 41: A strength athlete consumes 40g of protein post-workout. How does this compare to the evidence-based recommendation for maximizing muscle protein synthesis?

Insufficient; 50g is the minimum effective dose
Excessive; more than 30g is not utilized
At the upper range; 20–40g is optimal for most athletes (Correct answer)
Too low; at least 60g is needed

Correct answer: At the upper range; 20–40g is optimal for most athletes

Research supports 20–40g of high-quality protein post-exercise to maximize muscle protein synthesis, with larger athletes potentially benefiting from the higher end.

Question 42: An athlete's resting metabolic rate (RMR) measured by indirect calorimetry is 72% of the Cunningham-predicted RMR. This ratio suggests which condition?

Equipment calibration error requiring re-test
Normal metabolic variation
Elevated catecholamine response from overtraining
Metabolic adaptation consistent with low energy availability (Correct answer)

Recommend dietary iron sources only, as iron supplements never improve performance
Assess iron status via serum ferritin, hemoglobin, and transferrin saturation before recommending supplementation (Correct answer)

Correct answer: Assess iron status via serum ferritin, hemoglobin, and transferrin saturation before recommending supplementation

Iron status must be assessed through appropriate biomarkers before supplementation, as excessive iron can be harmful and supplementation is only beneficial when deficiency or insufficiency is confirmed.

Question 45: A gymnast has a BMI of 16.8 kg/m² and reports eating 1,400 kcal/day while training 30 hours per week. The dietitian calculates energy availability (EA). If the athlete's fat-free mass is 38 kg, what is EA (kcal/kg FFM/day)?

Approximately 45 kcal/kg FFM/day
Approximately 37 kcal/kg FFM/day
Approximately 18 kcal/kg FFM/day
Approximately 25 kcal/kg FFM/day (Correct answer)

Correct answer: Approximately 25 kcal/kg FFM/day

EA = (Energy intake − Exercise energy expenditure) / FFM; at 1,400 kcal intake with ~450 kcal/day exercise EE, EA ≈ 950/38 ≈ 25 kcal/kg FFM/day, below the 45 kcal threshold.

Question 46: A sports dietitian is reviewing a client's supplement stack that includes a pre-workout product containing both caffeine and synephrine. What is the primary safety concern with this combination?

Additive or synergistic stimulant effects increasing cardiovascular risk (Correct answer)
Synephrine blocks caffeine's ergogenic effects
Reduced caffeine bioavailability when taken together
Gastrointestinal distress exclusively, with no cardiovascular implications

Correct answer: Additive or synergistic stimulant effects increasing cardiovascular risk

Question 48: For an athlete gaining fat in the off-season, the MOST appropriate CSSD strategy is:

Adjust energy intake to account for reduced training load while maintaining nutritional quality (Correct answer)
Tell the athlete not to worry since off-season weight gain is always muscle
Prescribe the same competition diet year-round
Recommend a very strict diet immediately to prevent further gain

Correct answer: Adjust energy intake to account for reduced training load while maintaining nutritional quality

Off-season fat gain is commonly due to unchanged eating habits despite reduced training load; adjusting intake to match reduced expenditure prevents unnecessary fat accumulation.

Question 49: When assessing dietary intake via a 24-hour recall, which technique helps improve accuracy by prompting athletes to remember forgotten foods?

Multiple-Pass Method (Correct answer)
Diet History
Weighed Food Record
Food Frequency Questionnaire

Correct answer: Multiple-Pass Method

The Multiple-Pass Method uses structured probing passes to systematically reduce omission errors in 24-hour recalls.

Question 50: Which method is considered the criterion standard for measuring body composition in clinical and research settings, providing separate values for bone, fat, and lean mass?

Air displacement plethysmography (ADP)
Hydrostatic weighing
Dual-energy X-ray absorptiometry (DXA) (Correct answer)
Skinfold anthropometry

Correct answer: Dual-energy X-ray absorptiometry (DXA)

DXA uses two X-ray energies to differentiate bone mineral, fat mass, and lean soft tissue in a three-compartment model, making it the clinical gold standard.

Question 51: Which condition most significantly impairs the anabolic response to post-exercise protein intake in an endurance athlete?

Consuming protein within 30 minutes of finishing
Training in a carbohydrate-depleted state without subsequent carb intake (Correct answer)
Consuming protein with a high-fat meal
Using whey rather than casein protein post-exercise

Correct answer: Training in a carbohydrate-depleted state without subsequent carb intake

Severe glycogen depletion without carbohydrate recovery diverts amino acids toward gluconeogenesis rather than MPS, blunting the anabolic response to protein.

Question 52: A CSSD working with a team discovers that the medical staff has adopted a nutrition protocol based solely on a single industry-sponsored study. The most appropriate action is to:

Privately disregard the protocol for your own clients without informing anyone
Present a review of the broader evidence base to the medical staff and advocate for protocol revision if warranted (Correct answer)
Report the medical staff to the state licensing board immediately
Implement the protocol without question since it was medically approved

Correct answer: Present a review of the broader evidence base to the medical staff and advocate for protocol revision if warranted

Advocating for evidence-based practice within the care team through professional communication is both an ethical duty and the appropriate first step.

Question 53: What is carbohydrate loading used for?

Boosting iron levels
Reducing body fat
Increasing muscle size
Maximizing glycogen stores (Correct answer)

Correct answer: Maximizing glycogen stores

Carbohydrate loading is a nutritional strategy employed by endurance athletes to maximize the storage of glycogen in their muscles and liver. By increasing carbohydrate intake over several days leading up to a prolonged event, athletes can supercompensate their glycogen reserves. This increased fuel availability helps to delay fatigue and improve performance during long-duration activities.

Question 54: A track athlete reports unintentional weight loss of 4 kg over 6 weeks. After reviewing intake and expenditure, the dietitian identifies an energy deficit of approximately 600 kcal/day. Which physical assessment finding would MOST support this energy deficit estimate?

Increased muscle hypertrophy on skinfold assessment
Loss of approximately 3.5 kg of fat mass confirmed by DXA (Correct answer)
Increased resting heart rate within normal limits
Elevated serum albumin

Correct answer: Loss of approximately 3.5 kg of fat mass confirmed by DXA

A 600 kcal/day deficit over 42 days equals ~25,200 kcal, roughly equivalent to ~3.4 kg of fat (9,500 kcal/kg fat tissue), supporting the DXA finding.

Question 55: A competitive cyclist completing a 5-hour road race should target carbohydrate intake of approximately how many grams per hour during the event?

30–45 g/hour
60–90 g/hour (Correct answer)
100–120 g/hour
15–30 g/hour

Correct answer: 60–90 g/hour

Current guidelines recommend 60–90 g/hour of carbohydrates (using multi-transportable sources) for events exceeding 2.5 hours to sustain performance.

Question 56: Which form of creatine has the most robust scientific evidence supporting its safety and efficacy compared to other commercially available forms?

Creatine ethyl ester
Creatine monohydrate (Correct answer)
Creatine nitrate
Buffered creatine (Kre-Alkalyn)

Correct answer: Creatine monohydrate

Creatine monohydrate has the largest body of safety and efficacy evidence spanning decades of research, and no alternative form has been shown to be superior in well-controlled trials.

Question 57: A dietitian advises an athlete on nitrate supplementation via beetroot juice. What is the proposed ergogenic mechanism?

Increased testosterone secretion during exercise
Conversion to nitric oxide, improving oxygen efficiency and blood flow (Correct answer)
Enhanced carnosine synthesis in fast-twitch muscle fibers
Direct glycogen sparing through insulin sensitization

Correct answer: Conversion to nitric oxide, improving oxygen efficiency and blood flow

Dietary nitrates are reduced to nitric oxide in vivo, which vasodilates blood vessels, reduces the oxygen cost of exercise, and may enhance mitochondrial efficiency.

Question 58: Which bioelectrical impedance analysis (BIA) condition would MOST significantly underestimate body fat percentage?

Athlete is dehydrated after a long training session (Correct answer)
Athlete is well-hydrated after a rest day
Athlete is tested in a thermoneutral environment
Athlete has consumed a high-carbohydrate meal

Correct answer: Athlete is dehydrated after a long training session

Dehydration reduces total body water, decreasing conductance and causing BIA to underestimate fat-free mass and overestimate body fat percentage.

Question 59: Which principle is central to dietetic ethics?

Autonomy (Correct answer)
Bias
Authority
Deception

Correct answer: Autonomy

Autonomy is a fundamental ethical principle in dietetic practice, meaning the client's right to make their own informed decisions about their health and care. Dietitians are ethically obligated to respect a client's choices, values, and preferences, providing them with sufficient information to make autonomous decisions. This principle underpins informed consent and client-centered care.

Question 60: A male endurance athlete presents with low libido, fatigue, and stress fractures. Which condition best explains this cluster in the context of the Male Athlete Triad?

Primary hypogonadism
Iron deficiency anemia
Overtraining syndrome alone
Relative Energy Deficiency in Sport (RED-S) (Correct answer)

Correct answer: Relative Energy Deficiency in Sport (RED-S)

RED-S describes the broad health and performance consequences of low energy availability in male athletes, including hormonal and bone health impairments.

Question 61: During a 4-hour ultramarathon, an athlete's serum sodium drops to 128 mEq/L with no symptoms. According to current guidelines, what is the appropriate intervention?

Continue racing with no modification
Fluid restriction and sodium-rich foods until symptoms resolve or sodium normalizes (Correct answer)
Aggressive oral sodium supplementation regardless of fluid intake
IV saline bolus immediately

Correct answer: Fluid restriction and sodium-rich foods until symptoms resolve or sodium normalizes

Asymptomatic EAH is managed conservatively with fluid restriction and sodium replacement; IV fluids are reserved for symptomatic cases with altered mental status.

Question 62: Which meal composition strategy best supports liver glycogen resynthesis overnight for a morning training session?

Fat-dominant meal to spare glycogen
Casein protein shake only before bed
High-protein, low-carb evening meal
Moderate-to-high carbohydrate evening meal with adequate protein (Correct answer)

Correct answer: Moderate-to-high carbohydrate evening meal with adequate protein

Liver glycogen is depleted during the overnight fast, and a carbohydrate-rich evening meal helps restore hepatic stores prior to morning training.

Question 63: Which foundational principle is MOST important for success in the Board Certified Specialist in Sports Dietetics profession?

Maintaining the minimum requirements for certification
Specializing in only one narrow area of practice
Maximizing financial returns on every engagement

Magnesium

Correct answer: Sodium

Hyponatremia during prolonged exercise results from excessive sweat sodium losses combined with over-consumption of hypotonic fluids, diluting serum sodium below 135 mEq/L.

Question 133: Which of the following BEST describes the Cori cycle?

Transport of lactate from muscle to the liver, where it is converted to glucose via gluconeogenesis (Correct answer)
Re-synthesis of glycogen from ketone bodies
Conversion of alanine to glucose in the liver during exercise
Fatty acid esterification in adipose tissue

Correct answer: Transport of lactate from muscle to the liver, where it is converted to glucose via gluconeogenesis

The Cori cycle shuttles lactate produced by muscle to the liver, where it is converted back to glucose through gluconeogenesis and released into circulation.

Question 134: What is the key benefit of evidence-based decision making in CSSD management?

It improves accuracy and reduces bias in decisions (Correct answer)
It eliminates all risk
It reduces reliance on data
It speeds up all processes

Correct answer: It improves accuracy and reduces bias in decisions

Evidence-based decision making uses data and research to improve the accuracy of decisions and reduce the influence of personal bias.

Question 135: Which condition increases the risk of impaired recovery nutrition absorption and should prompt a sports dietitian to modify the post-exercise nutrition plan?

Short duration of exercise (<30 min)
Mild dehydration (1% BW loss)
Elevated heart rate post-exercise
Exercise-induced gastrointestinal distress (Correct answer)

Correct answer: Exercise-induced gastrointestinal distress

Exercise-induced GI distress can impair nutrient absorption and appetite, requiring modification of form (liquid vs. solid), timing, and composition of the recovery nutrition plan.

Question 136: Which tool is commonly used for dietary intake assessment?

Urine analysis
MRI scan
24-hour dietary recall (Correct answer)
Blood pressure monitor

Correct answer: 24-hour dietary recall

A 24-hour dietary recall is a commonly used tool for assessing dietary intake, where an individual reports all foods and beverages consumed over the past 24 hours. This method provides detailed information about specific food items, portion sizes, and preparation methods. While it relies on memory, it can offer a snapshot of typical intake and help identify dietary patterns or deficiencies relevant to an athlete's performance.

Question 137: What role does creatine phosphate play in energy metabolism?

Restores ATP in the phosphagen system (Correct answer)
Buffers lactic acid
Initiates glycolysis
Stores oxygen in muscles

Correct answer: Restores ATP in the phosphagen system

Creatine phosphate plays a critical role in the phosphagen energy system by rapidly regenerating ATP. When ATP is broken down for energy, ADP is formed; creatine phosphate donates its phosphate group to ADP, quickly converting it back to ATP. This allows for immediate, high-power muscle contractions for short bursts of activity, making it vital for explosive movements.

Question 138: Which gastrointestinal strategy is most important to implement during competition day for athletes prone to GI distress?

Consume hypertonic sports drinks for faster gastric emptying
Use casein protein supplements during warm-up
Increase fiber intake to slow glucose absorption
Avoid high-fat and high-fiber foods in the pre-competition meal (Correct answer)

Correct answer: Avoid high-fat and high-fiber foods in the pre-competition meal

High-fat and high-fiber foods slow gastric emptying and increase GI distress risk, so these should be avoided on competition day.

Question 139: Which serum marker is MOST useful for assessing chronic protein status and identifying protein-energy malnutrition in athletes with very low energy intake?

Ferritin
Creatinine
Albumin (Correct answer)
C-reactive protein

Correct answer: Albumin

Albumin, while slow to change, reflects chronic protein-energy status and is a marker of prolonged malnutrition when other confounders are ruled out.

Question 140: According to the IOC consensus on RED-S, which performance outcome is NOT directly linked to low energy availability?

Impaired coordination
Decreased muscle strength
Increased maximal oxygen uptake (VO2 max) (Correct answer)
Decreased endurance performance

Correct answer: Increased maximal oxygen uptake (VO2 max)

Low energy availability impairs multiple performance parameters but does not increase VO2 max; aerobic capacity is generally compromised or unchanged, not enhanced.

Question 141: Which skinfold site is included in both the Jackson-Pollock 3-site formula for women AND the 7-site formula?

Biceps
Triceps (Correct answer)
Abdominal
Midaxillary

Correct answer: Triceps

The triceps skinfold is included in the Jackson-Pollock 3-site (women: triceps, suprailiac, thigh) and the 7-site formula.

Question 142: What is the most important professional competency for CSSD certification in macronutrient timing?

Ability to work alone exclusively
Speed of task completion
Memorization of all reference materials
Deep knowledge combined with practical application skills (Correct answer)

Correct answer: Deep knowledge combined with practical application skills

Professional competency requires both deep knowledge of the subject matter and the ability to apply that knowledge in practical situations.

Question 143: An athlete with anorexia nervosa resumes eating after prolonged restriction. Which electrolyte abnormality is the primary concern during refeeding?

Hypercalcemia
Hypernatremia
Hypophosphatemia (Correct answer)
Hyperkalemia

Correct answer: Hypophosphatemia

Refeeding syndrome is characterized by a dangerous drop in serum phosphate as insulin drives phosphate into cells during renewed carbohydrate metabolism.

Question 144: Which anthropometric measure is used to assess body fat distribution?

Arm length
Shoe size
Waist circumference (Correct answer)
Height

Correct answer: Waist circumference

Waist circumference is a key anthropometric measure used to assess body fat distribution, particularly abdominal or visceral fat. A larger waist circumference is associated with an increased risk of metabolic syndrome, type 2 diabetes, and cardiovascular disease, even independent of overall body weight. It provides valuable insight beyond just BMI, indicating potential health risks related to central adiposity.

Question 145: An athlete completing a food record reports eating a 'medium banana.' To convert this to a quantitative nutrient value, the dietitian should FIRST consult which resource?

The athlete's training log
The athlete's team physician notes
USDA FoodData Central database (Correct answer)
A commercial food label

Correct answer: USDA FoodData Central database

USDA FoodData Central provides standardized nutrient values by food portion, making it the primary reference for converting food descriptions to nutrient data.

Question 146: What is a reliable source for nutrition evidence?

Personal blogs
Peer-reviewed journal articles (Correct answer)
Advertisements
Social media posts

Correct answer: Peer-reviewed journal articles

Peer-reviewed journal articles are considered a highly reliable source for nutrition evidence because they undergo a rigorous evaluation process by independent experts in the field before publication. This process ensures the quality, validity, and scientific merit of the research, making them a trustworthy foundation for evidence-based practice in dietetics.

Question 147: A female endurance athlete has a body fat percentage of 14%. According to sports nutrition guidelines, which statement best applies?

This percentage indicates low energy availability only if BMI is also below 18.5
This is below the essential fat threshold and requires immediate intervention
This level is associated with improved VO2max in all female athletes
This is within the healthy performance range for female endurance athletes (Correct answer)

Correct answer: This is within the healthy performance range for female endurance athletes

14% body fat falls within the accepted performance range for female endurance athletes (10–20%), and is above the essential fat threshold (~10–13%) for females.

Question 148: A Masters athlete (age 55) needs more protein post-exercise compared to a 25-year-old athlete for equivalent MPS stimulation. This phenomenon is called:

Leucine oxidation excess
Protein tolerance threshold
Anabolic resistance (Correct answer)
Sarcopenic catabolism

Correct answer: Anabolic resistance

Anabolic resistance refers to the blunted MPS response to protein and exercise seen in older adults, requiring higher protein doses (up to 40 g per meal) to achieve similar anabolic effects.

Question 149: How should a CSSD calculate an athlete's individualized fluid intake target during exercise?

A fixed 500 mL/hour for all athletes
Based on sweat rate testing: fluid intake ≈ sweat rate − acceptable deficit (no more than 2% BW) (Correct answer)
Match fluid intake exactly to sweat rate to maintain body weight
Drink until urine is clear regardless of intake volume

Correct answer: Based on sweat rate testing: fluid intake ≈ sweat rate − acceptable deficit (no more than 2% BW)

Individualized fluid targets are based on measured sweat rate, with intake adjusted to prevent losses exceeding 2% body weight while avoiding overdrinking.

Question 150: Which scenario represents a violation of the Board Certified Specialist in Sports Dietetics code of professional conduct?

Declining work outside one's area of competence
Reporting safety concerns to regulatory authorities
Misrepresenting qualifications or certification status (Correct answer)
Seeking continuing education beyond minimum requirements

Correct answer: Misrepresenting qualifications or certification status

Misrepresenting qualifications or certification status is a serious violation of professional conduct. It undermines public trust and can lead to harm when unqualified individuals perform specialized work.

Question 151: During team sport competitions with multiple games per day, what is the minimum carbohydrate intake recommendation between games of less than 4 hours?

1.0–1.2 g/kg body weight per hour (Correct answer)
0.5 g/kg body weight
No carbohydrate needed if protein is adequate
2.0 g/kg body weight total

Correct answer: 1.0–1.2 g/kg body weight per hour

To maximize glycogen resynthesis when recovery time is short (<4 hours), athletes should consume 1.0–1.2 g/kg/hour of rapidly digestible carbohydrates.
