Document Summary

Resistance training and gains in muscular fitness. Adaptations occur during chronic exercise but those adaptations depend on the type of training. Resistance training helps increase strength, power and endurance. Gains are expressed as a percentage of their initial stretch. Muscle is plastic- can increase and decrease in size and strength. Gains in muscle size= gains in strength. Muscle strength involves a lot more than just size. Neural control of muscle is changed to allow increased force production. Motor unit recruitment, stimulation frequency,and other neural factors are essential to gains. Explains strength gains in the absence of hypertrophy. Synchronization and recruitment of additional motor units. Motor units recruited asynchronously ; not called at the same time. Controlled by different neurons that can transmit either an excitatory or inhibitory impulse. The summation of many impulses in the motor unit either causes the muscle to contract or stay relaxed.
