Weight training has the biggest effect on the
skeletal muscles. When a person is engaged in weight training activities the
skeletal muscles are forced to move beyond their comfort zone because of the
added weight. As a result, muscle fibers develop micro-tears. These micro-tears
when they regenerate through time increases the number of muscle fibers and the
size of the fibers themselves.
The long
term effect of weight training not only builds muscles but also improves the
neuro-recruitment patterns of the muscles that are connected to the brain. When
this happens movements become more fluid and activities are easily performed
because of the developed connections of the muscle fibers to the brain.
