最大運動後の回復期に個人の無酸素的作業閾値を基準とした3種類の強度による運動回復を行ったところ，すべての被験者においてAT付近の運動回復が最もすみやかに血中乳酸を除去することがわかった。従来から，回復期の運動強度は，最大酸素摂取量の％水準を基準として処方されてきたが，ATを基準として処方した方が，血中乳酸除去にかかわる個人内変動を取り除くという点で意義があると考えられた。The purpose of this study was to investigate the optimal recovery intensity for effective blood lactate removal following maximal cycling exercise.Five male sujects performed cycling execise to volitional fatigue,followed by 20 minutes of rest or active recoveries based on anaerobic threshold(AT).The work rate of cycling exercise was initiated at 0w,and continuously increased by 20w every minute.The criterion for the determination of AT was a systematic increase in VEVO_2 without increase in VEVCO_2 during maximal cycling exercise.Blood lactate was determined before maximal exercise and every 5 minutes of recovery period.The optimal recovery intensity for blood lactate removal corresponded to the level of AT(40-60% VO_2 max).It is concluded that the active recovery based on AT eliminates the individual differences in blood lactate removal.
