| Research Abstract |
It was hypothesized that both muscle metaboreflex and arterial barorefelx contribute to regulate the heart rate and blood pressure during exercise and then the two reflexes were interplayed. This study investigated how the interplays changes in the different stimulus levels in muscle metaboreflex and in the different muscles activated (forearm and calf). Further, it was investigated whether the interplays change by the specific exercise training.
1) The increases in heart parasympathetic activity and the sensitivity of the arterial baroreflex on heart rate change (BRS) do not occur with the weak activation of muscle metaboreflex and do occur the above the threshold activation. Above the threshold, there is no gradual increase in heart parasympathetic activity and BRS.
2) The responses in heart parasympathetic activity and BRS during activation of the muscle metaboreflex are different between the different muscles activated.
3) The function of the muscle metaboreflex induced by handgrip exercise is not changed by the specific exercise training in competitive Badminton players.
