[Purpose] We examined the effects of detraining on temporal changes in arterial stiffness in endurance athletes. [Subjects] Eighteen female university athletes requiring high endurance exercise capabilities were classified into 2 groups: 10 retired players (detraining group) and 8 active players (training group). [Methods] Brachial-ankle pulse wave velocity, an index of arterial stiffness, was measured a total of 6 times: immediately before retirement of the detraining group and at 1, 2, 3, 6, and 12 months after retirement. [Results] Brachial-ankle pulse wave velocity was measured in the training group at the same 6 points to allow comparison with the detraining group. The brachial-ankle pulse wave velocity in the detraining group increased significantly at 3 and 12 months as compared with that at 0 months and showed a significant increase at 12 months compared with that at 1 month. Moreover, the brachial-ankle pulse wave velocity in the detraining group was significantly higher at 3, 6, and 12 months than in the training group. [Conclusion] These results revealed that detraining may result in increased arterial stiffness from 3 months onward in endurance athletes.
[目的]我们研究了耐力运动员停训对动脉僵硬度随时间变化的影响。[对象]18名需要高耐力运动能力的女大学生运动员被分为2组：10名退役运动员（停训组）和8名现役运动员（训练组）。[方法]共测量6次肱踝脉搏波速度，这是动脉僵硬度的一个指标：在停训组退役前即刻以及退役后1、2、3、6和12个月。[结果]在训练组的相同6个时间点测量肱踝脉搏波速度，以便与停训组进行比较。与0个月时相比，停训组的肱踝脉搏波速度在3个月和12个月时显著增加，与1个月时相比，在12个月时显著升高。此外，停训组在3、6和12个月时的肱踝脉搏波速度显著高于训练组。[结论]这些结果表明，耐力运动员从停训3个月起，动脉僵硬度可能会增加。
