DROPJUMP – an example, how to use it in a short period

Volleyball player Sandra Mattsson during dropjump training. Contact times (c-time) and her knee angles when switching from eccentric to concentric work corresponds very well to women Volleyball attacks. She shows good technique with extended ankles and hip and also keeping her head in a good position, trying to reach the sticks.

Her results in squat jump: 43,3 CMJ no arm swing: 50,0 CMJ with arm swing: 59,1
