Comparison of force-velocity profiles of the leg-extensors for elite athletes in the throwing events relating to gender, age and event
Strength capabilities of the leg-extending muscles play an important role in athletic throwing events, where a high momentum must be transferred to the throwing device. The objective of this study was to quantify the force-velocity profiles of the leg-extending muscles considering gender, age and event. The leg-extending forces of 143 elite-athletes (59 females, 84 males) of the athletic throwing events were measured during isokinetic leg press tasks at four speeds. The maxima of force, power and contraction velocity of a knee-extending model muscle could be determined by means of a scalable geometric model and linear fitting. This method makes different groups of athletes comparable. Furthermore, the individually achieved release speeds were measured in a field test. Female and male throwers showed a different development of force-velocity profiles during their maturation process. For the men the development is more speed-oriented. We identified shot putters and javelin throwers to be the athletes with the highest leg-extending power. The importance of leg-extending muscle strength for the complex field performance for the throwing events was confirmed. The presented approach allows to give support in controlling and guiding of leg-extension strength training for both different stages of maturing and varying throwing events.
