Objective To compare the influence of sports shoes with different sole thickness on the gait pa-rameters of high school students during the course of subjects walking at constant speed on the flat ground,the subjects wore sports shoes with different sole thickness for training,so as to explore the influence of sole thickness on the explosive power of high school students'lower limbs.Methods A total of 24 male high school students were randomly divided into four groups.They wore sports shoes with sole thickness of 0 cm,1 cm,2 cm and 3 cm to walk on the flat ground and their gait parameters were tested.After eight weeks of sports training,the dynamic indexes of standing long jump and squat jump were tested by wearing sports shoes with different sole thickness.The gait parameters and squat jump dynamics indexes were sta-tistically analyzed by one-way ANOVA.Results The gait period of the subjects with the thickness of the sole of the sneakers within 1～3 cm was longer,and the step length,step circumference,step speed and step frequency were all smaller than those wearing the sneakers with the thickness of the sole 0 cm.The fastest step speed and step frequency in the 0 cm group were(1.42±0.08)m/s and(1.75±0.03)m,respectively.The slowest stride speed and stride frequency of sneakers with 3 cm soles were(1.13±0.02)m/s and(1.49±0.04)m,respectively.After eight weeks of training,the performance of standing long jump increased by 0.14 m after wearing sneakers with 3 cm thickness.The improvement effect of squat jumping dynamic index was significantly higher than that of 0 cm sole thickness group.Conclusion Athletes wearing flat sports shoes walk more stably when walking on the flat,which can reduce the risk in exercise.Wearing thick soled sports shoes activates more muscle fibers during training,and has a more sig-nificant effect in improving the explosive power of athletes'lower limbs.Wearing sports shoes with sole thickness of 0 cm has no obvious advantage on the improvement effect of athletes.
