Evidence for Central Neural Regulation of Pacing Strategies / 中国运动医学杂志

ABSTRACT

Objective Based on the model of exercise induced central fatigue,we attempt to testify that the whole power output in time-counted sporting events was regulated by the central nervous system(CNS).Methods Eighteen national level rowers participated in the experiment.Each participant completed two successive 6 minutes maximal rowing exercise with an interval of 15 minutes.The power output(PO),heart rate(HR),blood lactate(BL),RPE and EMG were measured.Results It was demonstrated that the pacing strategies adopted by the rowers in the 2 successive 6-minute rowing tests were remarkably similar,and the rowers'PO and iEMG activities in the two tests were highly correlated,especially in the last minute of exercise.Conclusion It is concluded that the hypothesis of pacing strategy is controlled by CNS.
