Abstract
Isometric quadriceps exercises were performed at 2 different knee angles, 15.degree. and 60.degree., respectively. The maximal torque was measured in both positions before and after training in 10 healthy females. Both legs were exercised, 1 at each position. The purpose was to develop practical recommendations for choice of training position. The strength increase was mainly specific according to the angle at which the knee was exercised. Isometric exercise would preferably be performed at different knee angles to secure an optimal total strength increase. Isometric exercises improved dynamic strength at a low velocity but not at a high velocity.
