The Effect of Arm Movement on the Power Output of Vertical Jump

To test the contribution of arm movement to power in the vertical jump, 27 college-aged students (16 females, 11 males) performed two tests on a Just Jump Pad. Subjects jumped three times with arm movement, and three times without. Weight and average height jumped were used to calculate power output with the Lewis equation. To compare values we used a 2x2 analysis of variance with repeated measures test as well as independent t-tests between genders. Significantly greater power was produced using arms in both men and women (p=0.001). The independent t-test showed greater difference between jumps with and without arms for men (M ± SD= 341.49 ± 173.33 W) than women (M ± SD= 156.36 ± 58.93 W). These data suggest that arm movement during a vertical jump creates a higher power output than not using arms, with males having higher variability in power output with arms.
