Question

1. applying the principle of specificity means that you can increase a. abdominal strength by doing leg extensions. b. arm strength by doing push - ups. c. leg strength by doing pull - ups. d. shoulder strength by doing half squats. 17. teenagers who score below the health standard in a specific fitness component may need to a. decrease the length of time of their exercise sessions. b. increase the intensity of their workouts. c. increase the overload to the maximum. d. both a and b are correct.

Explanation:

1. The principle of specificity states that training should be specific to the muscle - group or skill you want to improve. Push - ups target the arm muscles, which aligns with the principle. Leg extensions target legs not abs, pull - ups target back and arms not legs, and half - squats target legs not shoulders.
2. Teenagers scoring below the health standard in a fitness component may need to increase the intensity of their workouts to improve their fitness level. Decreasing exercise session time is counterproductive, and increasing overload to the maximum is not a safe or advisable first step.

Answer:

1. B. arm strength by doing push - ups.
2. B. increase the intensity of their workouts.
