The purpose of this study was to investigate the influences of isometric training at different joint angles on the muscle size and function of the human muscle-tendon complex in vivo. Furthermore, we tried to gain a better understanding of the mechanisms involved in angle specificity after isometric training from the aspect of neuromuscular adaptation and(More)
The purpose of this study was to investigate the effects of series elasticity on the torque-angle relationship of the knee extensors in vivo. Forty-two men volunteered to take part in the present study. The participants performed maximal voluntary isometric contractions at eight knee-joint angles (40, 50, 60, 70, 80, 90, 100, 110 degrees). The elongation of(More)
In two groups of adult dogs with a femoral head prosthesis of either metal or ceramic implanted in the hip joint, the implanted prostheses were compared in terms of the associated gross, histologic changes of the articular cartilage. At 1 or 3 months after implantation the resulting damage to the articular cartilage was minimal in both groups. However, at 6(More)
