The aim of this study was to investigate whether vibration significantly affected the efficiency of off-road cyclists.
Eight male mountain cyclists (mean age 21.1±1 years; range, 19 to 22 years) between August 2017 and November 2017 were included. The experimental protocol included four testing sessions with a one-day interval between testing sessions: a familiarization session; performance of submaximal tests; performance of maximal graded exercise test; and a 30-min mountain bike trial performed with vibration or without vibration. Physiological measures including volume of oxygen uptake (VO), volume of ), VO, VCO, heart rate, respiratory exchange ratio, rating of perceived exertion, and gross efficiency (GE) were compared between the trials performed with vibration or without vibration.
There was a significant increase in the GE with the addition of intermittent vibration, particularly over the last 15 min of the cycling trial (p<0.05). There were no significant effects of vibration on other parameters.
This study demonstrates that addition of intermittent vibration may provide positive benefits in improving GE during a 30-min submaximal cycling trial.
本研究旨在调查振动是否会显著影响越野自行车骑行者的效率。
纳入了2017年8月至2017年11月期间的8名男性山地自行车骑行者（平均年龄21.1±1岁；年龄范围为19至22岁）。实验方案包括四个测试环节，各测试环节之间间隔一天：一个熟悉环节；次最大测试的表现；最大分级运动测试的表现；以及分别在有振动和无振动情况下进行的30分钟山地自行车试验。比较了在有振动和无振动情况下进行试验时的生理指标，包括摄氧量（VO）、二氧化碳排出量（VCO）、VO、心率、呼吸交换率、主观用力程度分级以及总效率（GE）。
添加间歇性振动后，总效率显著提高，尤其是在骑行试验的最后15分钟（p<0.05）。振动对其他参数没有显著影响。
本研究表明，在30分钟的次最大骑行试验中，添加间歇性振动可能对提高总效率有积极作用。
