Blood pressure, heart rate and CVRR (coefficient of variation of RR intervals in ECG) were measured between the group of 7 trained women and the group of 7 untrained ones during their mountain climbing on the hiking course (one way : 500 meter, height : 70 meter above sea, climbing speed: 50m/min, climb-down speed: 70m/min). Although heart rate, blood pressure and pressure rate product (PRP) increased in both groups, with the progress of exercise the values of the trained subjects were lower than those of the untrained after the exercise. In PRP, when they arrived at the top of the mountain, the values of untrained subjects became significantly higher than those of the trained, which suggested the increase of cardiac work on the part of the untrained ones. Trained subjects decreased in CVRR with the progress of the exercise, whereas untrained subjects increased in CVRR. After the exercise, trained subjects showed significant increase in CVRR than untrained ones. With the progress of exercise, trained women showed the decrease of excitation of vagal nerve activity, but they indicated the increase in CVRR in the process of the recovery from the exercise. Thus, vagal nerve activity plays an important role for the recovery of hemodynamics after the exercise.
