Fore foot area, length and breadth of fore foot as determinants in sprint and long distance running
Higher metabolic cost of propulsion leads to quicker depletion of muscle phosphagens and accumulation of lactic acid while sprinting and uneconomical metabolic cost leading to quicker fatigue while running long distances. Larger foot dimensions need more propulsive force. This study analysed correlation among the forefoot area, length and breadth of forefoot and maintenance of top sprinting speed and distance running capacity of individuals. Timings for last 40 m in 100 m run to understand sprint maintenance and 1500 m to understand distance run were correlated. Foot area of the subjects was measured by graph weighing method. Zero, first and second order partial correlations were applied to analyse results. Significant zero order positive correlations were found between foot area and sprint maintenance (r= 0.355) and distance running (r=0.225) at 0.05 level of significance. The positive correlations between fore foot area and the sprint maintenance timing (r 2 = 0.336) and fore foot area and distance running timing (r 2 = 0.213) were significant (at df 200; r=0.132) when the effect of fore foot length and breadth were removed by second order correlation. First order correlations also were significant between forefoot area and sprint maintenance (r 1 =0.345 and r 1 = 0.336, length and breadth effect removed, respectively) and distance running (r 1 = 0.224 and r 1 = 0.213, respectively). It appears the sprint maintenance ability during the last 40 m of 100 m and distance running capacity decreases with the increase in the area of the fore foot.
