| Abstract: | During the daily training of cyclists,they always use various gear ratio based on different training programs and requirements. According to the athletes training habits,this essay measures the frequently-used gear ratio which includes 50 ∶ 12,50 ∶ 13 and 50 ∶ 14 by means of stopwatch and SRM system. Then,to analysis the optimum gear ratio for each athletes and provide a theoretical basis to obtain the better performance in daily training and competition. |
