THE INFLUENCE OF MANUALLY ADJUSTING THE RUNNING SPEED ON THE IMPACT ACCELERATION OF THE TIBIA DURING TREADMILL RUNNING
Keywords: treadmill console, preferred speed, bilateral tibial accelerations
AbstractThe purpose of this study was to investigate the influence of pressing the speed key on the treadmill console to change the running speed on the impact acceleration of the tibia during treadmill running. Twenty-seven subjects were asked to run on the treadmill and increase the speed gradually until their preferred speed within two minutes. Then the subjects were required to adjust their running speed manually every two minutes. The peak impact accelerations of the right and left tibia were measured for 30 seconds at the 2nd, 4th, 6th, 8th, and 10thminutes. The results showed that there are greater peaks of impact acceleration of the tibia when some subjects pressed the speed key on the treadmill console to change their running speed. It is suggested that the position of the speed key of the treadmill be close to the runner.
