Özet
Objectives: The aim of this study was to investigate whether vibration significantly affected the efficiency of off-road cyclists.Patients and methods: 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 2 ), volume of carbon dioxide output (VCO 2 ), VO 2 , VCO 2 , heart rate, respiratory exchange ratio, rating of perceived exertion, and gross efficiency (GE) were compared between the trials performed with vibration or without vibration.Results: 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.Conclusion: This study demonstrates that addition of intermittent vibration may provide positive benefits in improving GE during a 30-min submaximal cycling trial.
