John has just started a resistance-training program. He realizes that he is becoming stronger, but does not notice increases in muscle size.
The reason behind the increased strength in the initial weeks of a resistance training program is the adaptation of neural condition.
<u>Explanation:</u>
The program of resistance training increases endurance and strength of muscle in young individual. However, the increase in the strength of the muscle in the early stage of this program is not related to the size of the muscle but the neural adapting condition of the body. The motor fibre of nerve and the fibre of muscle associated with it is the reason behind the early muscle strength in this program.
