Circadian rhythms during cycling exercise and finger-tapping task.

摘要: The aim of this study was to follow the circadian fluctuation spontaneous pedal rate and motor tempo (MST) in a sample highly trained cyclists. Ten subjects performed five test sessions at various times day. During each session, were required perform (i) finger-tapping task, order set MST (ii) submaximal exercise on cycle ergometer for 15 min 50% their Wmax. For exercise, freely chosen. Spontaneous heart (HR) measured continuously. results demonstrated variation mean oral temperature, HR, MST. Under conditions, HR showed no significant time-of-day influence although changed significantly throughout Circadian rhythm temperature strongly correlated. Moreover, positive correlation found between rate. Both parameters may be controlled by common brain oscillator. MST, rest changes internal which is considered major marker chronobiology, therefore, if there relation rate, we cannot rule out partial dependence both body temperature.
