ABSTRACT:
The explosive strengths of 361 young and 10 adult male athletes were evaluated by a vertical jumping and a ball-throwing test. The young athletes were representing seven different sports events: track and field, apparatus gymnastics, basketball, ice hockey, orienteering, skiing, and wrestling. The adult subjects were volleyball players. Weighted vertical counter-movement jumps were performed on a platform connected to an electronic unit which calculated the height of the rise of the body's center of gravity. For the stationary ball throwing test, horizontal throwing velocity was measured for balls of different masses by an electrical apparatus. Interevent differences in reliability were minor in the throwing test while, in the jumping test, apparatus gymnasts achieved the most reliable results and the wrestlers the least reliable results. The reliabilities for throwing lighter objects and jumping with lighter loads were better than for the heavier objects and loads, as measured by the coefficient of variation. The results of the new jumping and throwing tests showed rather high correlations as compared with the respective traditional field tests.
