Final answer:
The statement regarding maximum power occurring between 55% to 85% of 1RM is true as it allows for optimal speed and force during weightlifting, leading to maximum power output.
Step-by-step explanation:
The statement that maximum power will occur somewhere between 55% to 85% of 1RM is TRUE. When training for power, athletes often work with weights that are a fraction of their one-repetition maximum (1RM), which is the maximum amount of weight that a person can lift for one repetition of an exercise. The specified range allows for optimal speed and force production while lifting, leading to maximum power output. Lifting with lighter or heavier weights than this range may result in less power production because of insufficient speed or insufficient force, respectively.
