You have been asked to design a resistance training program for an experienced weight lifter who is training for maximal power. Briefly explain the importance of repetition velocity in power development
Because adaptations are specific to repetition velocity, optimal gains in power output are seen following high-velocity training. Therefore, repetitions should be performed at a fast velocity. Furthermore, when high-intensity exercises are incorporated into the program, although the actual movement might be slow, the athlete should focus on the intent to lift the bar quickly because this will enhance gains in power.
Greater strength gains are seen when athletes use only concentric muscle actions during resistance training. A) True B) False
b
Explain the steps for 1RM testing.
Do a warm-up set of 5 to 10 repetitions at 40% to 60% of estimated 1RM. After a brief rest, do a second warm-up set of 3 to 5 repetitions at 60% to 80% of estimated 1RM. After 3 to 5 minutes rest, attempt the 1RM. If successful, conservatively increase the weight until failure. The 1RM is the greatest weight successfully lifted.

Briefly describe the differences between strength training and muscular endurance training with respect to training intensity (load), number of repetitions per set, and interest rest periods.
In general, strength training is associated with high intensity (>85% 1-RM), low repetitions (<6 reps per set) and long rest periods (~2-3minutes between sets). Alternately, muscular endurance training is associated with low intensity (<70% 1-RM), high repetitions (>10 reps per set), and short rest periods (1-2 minutes between sets).
Two basketball players are looking to increase muscle size by resistance training. One has 75% fast-twitch muscle fibers and this other has 50% fast-twitch fibers. Who is more likely to see greater gains in muscle size and why?
Fast-twitch (type II) muscle fibers have a greater capacity for hypertrophy than slow-twitch (type I) fibers. Therefore, the athlete with a greater amount of fast-twitch fibers is more likely to see greater gains in muscle size.
