The Relationship of Hill Training With Stride Rate among Under 17 Year Athletics Trainees

INTRODUCTION In the study of Gottschall and Kram, 2005 , the subjects run at 0, 3, 6, and 9% slope at a constant velocity. He reported a slight decrease in SL and an increase in step frequency as the slope increased. We assume that kinematic parameters, and metabolic factors, may contribute to the running performance. Moreover, a specific training on slop es to improve cardiovascular conditions and to increase strength is used by distance runner (Minetti et al., 1994). When running uphill, increase stride rate and shorten your stride slightly, which will keep your center of gravity over or slightly ahead o f your lead foot, and lift your knees a little more than usual on the flats. Also, increase your arm swing slightly. Driving the arms a little harder will help to overcome the pull of gravity. When running downhill, lengthen your stride a little and pay attention to your foot strike. Avoid a hard heel strike, which indicates that you are leaning back and over striding with your knees too straight or locked and a lot of shock transmitted to your legs, knees, and hips. Try to land mid foot or forefoot with yo ur knees flexed. A gentle heel strike followed by a quick roll onto the forefoot is ok if "forcing" a mid foot landing isn't comfortable. Unlike running uphill, an exaggerated arm swing is counter -productive when running downhill. Gra
