Abstract

Running is a widely-used human movement pattern. In terms of evolution, running has developed primarily for endurance because speed was not a major factor in determining the biological success of humans. Forty thousand years ago this endurance-oriented jog-trot action was used for hunting and gathering and, since that time, no major anatomical changes have occurred in the running apparatus. Jogging is experiencing popularity also because of its physiological benefits. However, if guidelines for optimal performance are unavailable or ignored, then unused overweight bodies may place undue strain on the musculo-skeletal system through inappropriate application of forces during thejogging cycle. The present study sought to examine the freely chosen stridelength and stride-rate changes while running on a treadmill at 4 graded velocities. Verf.-Referat
