Training for Special Populations Flashcards

A 68-year-old male client, who is deconditioned but has been cleared for exercise, wants to improve his ability to quickly react to a loss of balance to prevent falls. Which type of training would be MOST important to incorporate into his program to specifically address this goal?

Answer: Power exercises, such as medicine ball chest passes and rapid sit-to-stands.

For older adults, the ability to prevent a fall is directly related to the rate of force development (power), not just maximal strength. Power training improves the speed at which muscles can contract to correct a loss of balance. Exercises like rapid sit-to-stands and medicine ball passes improve this neuromuscular reactivity, which is crucial for fall prevention. [14, 23]

A client in her second trimester of pregnancy (20 weeks) is performing a workout. Which of the following exercises should be immediately modified or discontinued due to her stage of pregnancy?

Answer: Standard barbell deadlifts performed from the floor.

After the first trimester (around 16-20 weeks), exercises performed in the supine (flat on the back) position should be avoided due to the risk of supine hypotensive syndrome, where the weight of the uterus can compress the vena cava and restrict blood flow. [2, 12, 16] Standard barbell deadlifts require a significant forward lean and place pressure on the abdomen, which should also be modified. Of the options provided, the standard deadlift is the most concerning and requires modification (e.g., using a trap bar or dumbbells) or discontinuation. The other exercises are generally considered safe with proper form.

A personal trainer is designing a resistance training program for a 14-year-old who is new to lifting weights. Which of the following is the MOST important initial focus for this client?

Answer: Mastering proper exercise technique and motor patterns with light resistance.

The primary focus for youth resistance training, especially for beginners, should be on learning and mastering proper form and technique. [8, 10, 26] This ensures safety, builds a strong neuromuscular foundation, and reduces the risk of injury to developing growth plates. [10] Maximal lifts and high-intensity plyometrics are not recommended until a solid base of strength and technical proficiency is established. [3, 10, 18]

A client with controlled Type 2 diabetes and clearance for exercise checks their blood glucose before a workout, and the reading is 270 mg/dL with no ketones present. What is the most appropriate course of action for the trainer?

Answer: Proceed with the planned low-to-moderate intensity workout while monitoring the client for any adverse symptoms.

According to ACSM and NFPT guidelines, if a client with diabetes has a pre-exercise blood glucose level over 250 mg/dL, the trainer should check for ketones. [13, 19] If no ketones are present, the client can typically proceed with caution, engaging in low-to-moderate intensity exercise. [19] It is crucial to stay hydrated and monitor for any signs of fatigue or illness. High-intensity exercise should be avoided, and a pre-workout snack is unnecessary and counterproductive at this glucose level.

When designing a program for a client with obesity, which of the following is a primary consideration to ensure safety and adherence?

Answer: Focusing on exercises that minimize stress on the joints, such as swimming or using a recumbent bike.

Clients with obesity often experience joint pain, particularly in the knees, hips, and lower back, due to excess body weight. Therefore, a primary consideration is to select low-impact exercises that reduce stress on these joints. [7, 32] Activities like swimming, water aerobics, and cycling (especially on a recumbent bike) are excellent choices that allow for cardiovascular conditioning and caloric expenditure with a lower risk of orthopedic injury, which improves comfort and long-term adherence. [7, 24]

Which of the following should be avoided by a client with severe, uncontrolled hypertension?

Answer: Resistance training using the Valsalva maneuver.

The Valsalva maneuver, which involves forcibly exhaling against a closed airway, dramatically increases intrathoracic and blood pressure. [1, 37, 42] For an individual with uncontrolled hypertension, this sharp spike in blood pressure can be dangerous and significantly increase the risk of a cardiovascular event. Trainers should instruct these clients to breathe continuously throughout each repetition.
