A Comparison Of Isokinetic Ankle Plantarflexion Force Generation In Knee Flexed And Knee Extended Positions, Reyn Hata, Delbert Peralta, Daniel Uyeunten

Physical Therapy Scholarly Projects

The triceps surae, composed of the soleus and the two heads of the gastrocnemius, is a very active muscle in all activities involving the lower extremities. This study compared the maximal force generated by these ankle plantarflexors in a knee extended and knee flexed position to determine relative contribution to plantarflexion force in varying positions. Eighteen male and female college students were tested for maximal concentric plantarflexor force generation isokinetically at 3D/sec in both positions. Means of maximal force in knee extension and flexion, 242.56 Ibs. and 227.22 Ibs., respectively, were found to be statistically significantly different. The mean of …
