To compare the acute effects of low-volume intermittent and higher-volume continuous exercise on arterial stiffness, 20 healthy men (22.4 ± 0.4 years) were randomized to non-exercise control (CON), high-volume Continuous Exercise (CE), lower-volume Intermittent exercise of Long bouts with Long interval (ILL), of Long bouts with Short interval (ILS), and of Short bouts with Short interval trial (ISS). Exercise intensity was 35% heart rate reserve. Arterial stiffness in Cardio-ankle vascular index (CAVI) was measured at baseline (BL), immediately (0 min) and 40 min after exercise. CAVI changes from BL in the same trial (⊿CAVI) were used for analysis. There was no significant ⊿CAVI change in CON. ⊿CAVI decreased significantly at 0 min in all exercise trials, and reverted to baseline at 40 min only in CE and ILL. At 40 min, ⊿CAVI in ILS and ISS remained significantly lower than that of CON and CE. When ILS and ISS were compared with CON at 40 min, only ⊿CAVI in ISS remained significantly lower than that of CON. Despite low volume, the effect of intermittent exercise on arterial stiffness could be either equal or superior to that of higher-volume continuous exercise.
为了比较低容量间歇性和高容量连续性运动对动脉僵硬度的急性影响，20 名健康男性（22.4±0.4 岁）被随机分为非运动对照组（CON）、高容量连续性运动组（CE）、长间隔长回合间歇性运动组（ILL）、短间隔长回合间歇性运动组（ILS）和短间隔短回合间歇性运动组（ISS）。运动强度为 35%心率储备。在基线（BL）、运动后即刻（0 分钟）和 40 分钟时测量心血管踝指数（CAVI）的动脉僵硬度。同试验中 CAVI 从 BL 的变化（⊿CAVI）用于分析。CON 组的⊿CAVI 无显著变化。在所有运动试验中，0 分钟时⊿CAVI 均显著下降，仅在 CE 和 ILL 组中 40 分钟时恢复到基线。在 40 分钟时，ILS 和 ISS 的⊿CAVI 仍明显低于 CON 和 CE。与 CON 相比，40 分钟时 ILS 和 ISS 的⊿CAVI 仍显著低于 CON。尽管容量低，但间歇性运动对动脉僵硬度的影响可能与高容量连续性运动一样或更好。
