THE OPTIMUM INTENSITY AND MODE OF COOLING DOWN PROCEDURES AFTER POST REPETITIVE INTERMITTENT HIGH-INTENSITY EXERCISE / 体力科学

ABSTRACT

The purpose of this study was to compare the effects derived from different modes of active cooling down procedures post repetitive intermittent high-intensity exercise. Seven Japanese male swimmers underwent repetitive 3 bouts of Wingate anaerobic tests on the 1^st day and another Wingate on the following 2^nd day. In each 3 intervals and post all the Wingate testing on the 2^nd day, the participants performed a cooling down randomly chosen from 3 different intensities of 10-min bike-riding and a 10-min static stretching. As to muscle power outputs and emotional conditions, the optimum cooling down intensities were observed at 80% ventilatoly threshold (VT) after the 1^st set and 60% VT level after the 2^nd set. Effective intensities of blood lactate removal rate were observed at 60% and 80% VT level. Thus, the optimum cooling down post repetitive intermittent high-intensity exercise could be dynamic bike-riding at 60% or 80% VT level.
