CSCS Periodization & Energy Systems 4 — Questions and Answers
Question 1: What does the term 'supercompensation' describe in the context of periodization?
- The peak overload phase during intensification
- The temporary fitness decline following a deload
- The elevated fitness state after recovery from training stress (Correct answer)
- The plateau effect when adaptation stalls
Correct answer: The elevated fitness state after recovery from training stress
Supercompensation is the phase where fitness temporarily rises above baseline after adequate recovery from a training stimulus.
Question 2: Which CSCS-relevant concept describes organizing training into large, concentrated blocks focused on one quality at a time?
- Concurrent training
- Block periodization (Correct answer)
- Undulating periodization
- Reverse linear periodization
Correct answer: Block periodization
Block periodization (Issurin model) focuses each block on one or two dominant training qualities, allowing concentrated adaptation before the next block.
Question 3: Oxygen deficit occurs at the beginning of exercise because:
- The lungs cannot absorb oxygen fast enough
- Cardiorespiratory adjustments lag behind the immediate energy demand (Correct answer)
- The mitochondria are inactive at exercise onset
- Fat oxidation produces less oxygen than carbohydrate oxidation
Correct answer: Cardiorespiratory adjustments lag behind the immediate energy demand
At exercise onset, cardiorespiratory adjustments are delayed, so anaerobic pathways bridge the gap between O2 supply and demand, creating an oxygen deficit.
Question 4: A strength and conditioning coach observing an athlete's 10-second all-out sprint relies primarily on which ATP resynthesis pathway?
- Oxidative phosphorylation
- Slow glycolysis
- Fast glycolysis
- Phosphagen system (ATP-PCr) (Correct answer)
Correct answer: Phosphagen system (ATP-PCr)
Maximal efforts lasting approximately 0–10 seconds are fueled almost entirely by the phosphagen system using stored ATP and phosphocreatine.
Question 5: Which of the following best describes the concept of 'training monotony' and its risk?
- Repeating the same exercises causes boredom and dropout
- Insufficient variation in daily training load increases overtraining risk (Correct answer)
- Excessive volume in a single session reduces power output
- Lack of periodization leads to strength plateaus after 6 months
Correct answer: Insufficient variation in daily training load increases overtraining risk
Training monotony (low day-to-day load variation) is associated with increased overtraining risk and is measured by dividing mean load by its standard deviation.
Question 6: Aerobic capacity (VO2max) is best improved through training at what percentage of VO2max?
- 40–50%
- 55–65%
- 85–95% (Correct answer)
- 100–110%
Correct answer: 85–95%
High-intensity interval training near or slightly above VO2max (85–100%+) produces the greatest improvements in maximal aerobic capacity.
Question 7: In periodization terminology, what is a 'deload' week designed to accomplish?
- Test maximal strength before the next phase
- Introduce a new exercise selection for variation
- Reduce accumulated fatigue to allow adaptation to emerge (Correct answer)
- Switch from strength training to cardiovascular conditioning
Correct answer: Reduce accumulated fatigue to allow adaptation to emerge
A deload week reduces training volume and/or intensity to dissipate accumulated fatigue, allowing positive adaptations (supercompensation) to surface.
