The effect of stride frequency, stride length, and stride time on sprint patterns
Abstract
The research has been done to explain the complex interrelation of three important parameters of the sprinters-stride frequency, stride length, and step time-in the case of a national athlete HTY during the 100 meters sprint. Stride length refers to the distance covered in one complete step, while stride frequency is defined as the number of steps one makes in a unit of time. Previous studies have shown that both these two variables are related in a complex way. Usually, if one increases, the other decreases because of biomechanical limitation. This paper is a quantitative description, and performance variables of HTY were analysed through video analysis software namely, Kinovea. The results showed that HTY finished the race with 13.24 seconds and an average of 172.85 cm stride length with a total of 57 steps. Variabilities in speed during successive intervals, such as the peak from the 10-20-meter interval, were analysed. The results show that literature supports stride frequency and length significantly influence sprint performance. More precisely, it is proven that there is room for improvement in the specific strengthening exercises by the fact that the measured stride time differs between legs. Fine-tuning in the relationship between stride frequency and length is the most important in enhancing sprint performance. The study gives some useful suggestions for coaches and athletes in the modification of their training strategies, thereby improving the overall efficiency in sprinting.
