Question
Chapter 10, Problem 8CRCAQ
Summary Introduction
To review:
The increase of muscle strength with weight training.
Introduction:
The diameter and strength of muscle fibers can be increased through weight training. In response to mechanical stress, the satellite cells differentiate into myoblast that fuses with muscle fibers to provide additional nuclei for the synthesis of large amount of contractile proteins, myofilaments, and myofibrils.

Students have asked these similar questions
Given what you have learned about increasing muscle strength through weight training, why do athletes taper off their training regimen prior to a major competitive event?
In some fitness exercises you will build muscle mass but do not train the muscle to be effective. What type of training will do that and why do people do these types of trainings?
How would ine generate more muscle tension to pick up something heavy?
Increase activation of motor units
Increase muscle tone
Decrease calcium release
Decrease muscle hypertrophy
Decrease muscle hyperplasia
