Question

1. What changes occur to the muscular system after strength training in adults? Be sure to include changes in muscle size, metabolic adaptations, neural adaptations, and effects on muscle fiber number. (minimum 4 changes).

I need help with this question thank you!

Answer 1

Muscle size : As strength training requires the muscles to do more work, the muscles adapt themselves by increasing their size. As a result of exercise, he muscle fiber size increases.

Metabolic adaptations : As muscles require more energy during training, the body stores more phosphocreatine and carbohydrate in the muscle for faster production of ATP.

Neural adaptations : the brain sends continuous signals to work he muscles during exercise. The neural system recruits more muscles and also the reflexes become faster.

Muscle fiber number : More and more muscle fibers are recruited by the neural system and their number increases.
