Outline of Final Research Achievements |
We investigated how resistance training (RT) to failure at low load affects acute responses and chronic muscle adaptations compared with low-load RT to velocity fatigue at equal work volume. Twenty-seven subjects performed 8 weeks of bench press twice weekly. Participants were randomly assigned to one of three groups: low-load volitional failure (LVoF, n=9), low-load velocity fatigue (LVeF, n=8), and high-load (HL, n=10). RT comprised 3 sets to failure at 40% one repetition maximum (1RM) in the LVoF group, 3 sets to velocity fatigue (20% lifting velocity loss) at 40% 1RM in the LVeF group, and 3 sets of 8 repetitions at 80% 1RM in the HL group. In conclusion, low-load RT to volitional failure induces muscle hypertrophy similar to volume-matched velocity fatigue.

Academic Significance and Societal Importance of the Research Achievements |
最大挙上回数まで行うトレーニングの有用性を低強度の筋力トレーニングを用いて検討した。その結果、トレーニングをあまり行っていない対象者であれば、最大挙上回数までおこなわかったとしても高強度と同様に筋肥大することが明らかになった。最大反復までのトレーニングは、筋損傷などを起こすことも報告されていることから、速度の低下などを利用することで、アスリートのインシーズンのトレーニングや、健康増進を目的とした一般の人のトレーニングのプログラム計画に有効である。
