Outline of Final Research Achievements

This study aimed to examine the effects of short-term aerobic training on aerobic work capacity and heart rate variability (HRV) with relation to training load. A 5-week training program was consisted of overloading and tapering periodization. We measured external (work) and internal (heart rate) training load, parasympathetic activity (as measured via the natural logarithm of the root mean squared standard deviation (LnRMSSD)), and aerobic work capacity, respectively. As the results, aerobic work capacity and variation in LnRMSSD were associated with internal load rather than external load. The variation in LnRMSSD was not related to the relative changes in aerobic work capacity.

Academic Significance and Societal Importance of the Research Achievements

短期間のエアロビックトレーニングの効果には，個人差がある。一般的に，外的負荷（ペダルの仕事量や走速度など）に基づいてトレーニング強度を設定するが，相対強度が同一であっても内的負荷（心拍数など）に個人差が生じる。本研究の結果は，外的負荷よりも内的負荷が有酸素性作業能力および心拍変動と関連したことから，トレーニングを行う際に内的負荷に基づいた強度設定をする必要があるということが提案できる。
