Abstract des Autors
Maximal and mean power outputs were measured in young tennis players (22 boys and 18 girls) performing 3 laboratory tests of short duration: counter-movement jump (CMJ), leg exercise on a pendulum device (PEN) and leg flexion/extension under isokinetic conditions (ARI). Highest values of maximal power output (Pm) were attained in the CMJ test (boys: 1979+/-497 W, girls: 1613+/-342 W) and were significantly higher from those recorded in either PEN or ARI (boys: 1424+/-332 and 1268+/-308 W, girls: 1224+/-337 and 1046+/-186 W, respectively). Values obtained in CMJ and ARI tests significantly correlated with each other regarding maximum and mean power values, but not between CMJ-PEN or ARI-PEN. Significant correlations between CMJ and
ARI were found for both flexors and extensors of the knee joint. The lack of correlations between power output values generated by young male and female tennis players in various tests of short duration do not support the view that in maximal efforts, the power potential of lower limbs may be independent from the kind of exercise.
