SPEED OF MOVEMENT, NOT MAXIMAL STRENGTH, IS IMPORTANT FOR JUMPING
Young, W., Wilson, G., & Byrne, C. (1999). Relationship between strength qualities and performance in standing and run-up vertical jumps. Journal of Sports Medicine and Physical Fitness, 39, 285-293.
The relationships between strength qualities of leg extensor muscles and performance in vertical jumps, from both standing and 1, 3, 5, and 7-step run-up approaches, were evaluated. Males (N = 29) experienced in jumping activities served as S.
Speed-strength tests correlated significantly with both types of jumps, but maximum strength did not.
Implication. To improve jumping ability, the development of speed-strength movements is more important than maximum strength (usually developed by slow heavy resistance training).
