Document Summary
Resistance training plus aerobic training equals less strength and power improvement. Health benefits of both types of training may be obtained by training for both strength and endurance in general population. Some machines have tried to overcome this by using cams- variable resistance training equipment. Faster speeds result in increased size of type iix fibers. More increases in power seen in both fast and slow movements when fast training is used. Problems: expensive; can"t accommodate actual high speeds used in many sports; can"t overload eccentric actions. Use explosive jumps to mobilize the stretch-recoil properties of muscles. Stretch-shortening cycle produces more powerful movement due to: Activation of the stretch reflex ( and muscle spindles) Allows athlete to develop greater power at the end of the movement and also achieves greater muscle activation overall. Stimulates sports performance more closely then regular lifting. Drop jumps generate forces of up to 10x body weight.
