| Abstract: | Abstract To determine the relationship between the extension power of the arms and power of the legs, 26 male Macalester College students were tested on a modified Biokinetic Swim Bench. All measurements were measured accurately and reliably. Correlations between individual abilities on the leg extension and the arm extension tasks are low, r =.194. Between the right arm and the right leg the r = .041; and between the left arm and the left leg the r = .227. These correlations are not significant. It was concluded that extension power abilities are highly specific in nature and that assuming arm power from a leg power measurement is not a viable alternative to actual measurement of the arm power. |
