Effect Of Flywheel Training On Running Economy In Male College Students

Objective:study the effect of Flywheel Training（FT）on Running Economy（RE）of male college students.Methods:recruit twenty-two male college students and divided them into experimental group（Flywheel,F）and control group（Control,C）randomly.The training program of group C is physical fitness training 3 times a week and 5-10km running 3 times a week.The specific program of physical fitness is:60 times of leg lifts,60 times of hamstring,10kg*20 times of quick jerk,20 times of abdominal curl,60 seconds of flat support*3 groups for 6 weeks,each 3 times a week.The F group received the Flywbeel squat training program of 4 groups*7,with 3 minutes rest between groups.3 times a week on the basis of the training program of the C group.The load:one large flywheel 0.02 kg·m2 for inertia load,and one larger flywheel0.06 kg·m2.VO2max,running distance and heart rate,VE,VCO2,time and speed,different VO2max level（65%VO2max,75%VO2max,85%VO2max）under the corresponding rate of RE,Counter Movement Jump（CMJ）,Static Jump altitude and performance parameters:Eccentric Utilization Ratio（EUR）and Rate of Force Development（RFD）were measured respectively before and after the 6-weeks experiment.Results:（1）the VO2max of participants in group C and group F significantly decreased after 6 weeks compared with that before the experiment（P<0.01,ES=0.22;P<0.01,ES=0.35）;（2）compared with before the experiment,the RE in group F at65%VO2max,75%VO2max and 85%VO2max decreased significantly（P<0.01,ES=0.76;P<0.01,ES=1.04;P<0.01,ES=1.85）;（3）compared with before the experiment,the height of（SJ,CMJ）in group F was significantly increased（P<0.01,ES=0.73;P<0.01,ES=1.15）;And EUR,SJ_RFDand CMJ_RFDwere significantly improved（P<0.05,ES=0.44;P<0.05,ES=0.46;P<0.01,ES=0.66）;group F was significantly lower than group C（P<0.05,ES=0.30）corresponding to 85%VO2max on RE.Conclusion:（1）Flywheel training improves the muscle hardness and other neuromuscular functions,strengthens the athlete’s running economy,and improves65%,75%,and 85%RE,which helps improve endurance performance.（2）Flywheel training has a positive effect on SJ,CMJ,RFD,EUR and other lower limb elastic potential energy indicators.Future training can use flywheel training to improve individual explosive power and other abilities.
