「Serum testosterone responses to continuous and intermittent exercise training in male rats」

Serum testosterone (T) were investigated at rest and following exercise during 6 weeks of continuous and intermittent training in male rats. Although resting T was not affected by intermittent training, continuous training induced a lower resting T level at the end of 3 weeks. (雄ラットを用い、持久トレーニング群と間欠的トレーニングﾞ群（各6週間）を設けてテストステロン（T）への影響を検討した。間欠的トレーニングﾞ群では安静時Tは変化しなかったが、持続トレーニング群では、トレーニング3週間後に安静時Tの低下が認められた。)
