The present study examined the effects of respiratory muscle training in which the participants used a nose clip on physiological functions and running performance. The participants were 8 university and graduate school students (3 men, 5 women) who ran regularly. They were divided into 2 groups: a nose-clip group (N=4) who used a nose clip, and a control group (N=4) who did not use a nose clip. Both groups were trained for 4 weeks, then switched to the other procedure for another 4 weeks of training (crossover experiment). They were tested 3 times on a treadmill test with incrementally increasing loads: before training, after the first 4 weeks of training, and after the final 4 weeks of training. The results indicated that only the nose-clip group improved their running speed on the treadmill, extending their all-out distance by 6 meters (2.4%) and their duration by 0.6 minutes (4.8%). Furthermore, their running speed at their ventilation threshold increased by 13m/min (7.6%, p<0.05). However, causes of the improvement in aerobic physiologic responses could not be identified. Future research should extend the period of respiratory muscle training beyond one month and include investigation of the physiological mechanisms underlying improved performance.}, pages = {375--387}, title = {ノーズクリップを用いた呼吸筋トレーニングが有酸素性の生理的応答やパフォーマンスに与える影響}, volume = {8}, year = {2016}, yomi = {ナベクラ, ヨシハル} }
