To determine whether high-intensity training with voluntary hypoventilation at low lung volume (VHL) in cycling could improve running performance in team-sport athletes.
Twenty well-fit subjects competing in different team sports completed, over a 3-week period, 6 high-intensity training sessions in cycling (repeated 8-s exercise bouts at 150% of maximal aerobic power) either with VHL or with normal breathing conditions. Before (Pre) and after (Post) training, the subjects performed a repeated-sprint-ability test (RSA) in running (12 × 20-m all-out sprints), a 200-m maximal run, and the Yo-Yo Intermittent Recovery Level 1 test (YYIR1).
There was no difference between Pre and Post in the mean and best velocities reached in the RSA test, as well as in performance and maximal blood lactate concentration in the 200-m-run trial in both groups. On the other hand, performance was greater in the second part of the RSA test, and the fatigue index of this test was lower (5.18% [1.3%] vs 7.72% [1.6%]; P < .01) after the VHL intervention only. Performance was also greater in the YYIR1 in the VHL group (1468 [313] vs 1111 [248] m; P < .01), whereas no change occurred in the normal-breathing-condition group.
This study showed that performing high-intensity cycle training with VHL could improve RSA and possibly endurance performance in running. On the other hand, this kind of approach does not seem to induce transferable benefits for anaerobic performance.
确定在骑行中进行低肺容量（VHL）下的自愿性低通气高强度训练是否能提高团队运动运动员的跑步成绩。
20名参加不同团队运动的健康受试者在3周内完成了6次骑行高强度训练课程（以最大有氧功率的150%进行重复8秒运动 bout），训练时采用VHL或正常呼吸条件。在训练前（Pre）和训练后（Post），受试者进行了跑步重复冲刺能力测试（RSA）（12次×20米全力冲刺）、200米最大跑测试以及Yo-Yo间歇恢复水平1测试（YYIR1）。
两组在RSA测试中达到的平均速度和最佳速度、200米跑测试中的成绩以及最大血乳酸浓度方面，训练前后均无差异。另一方面，仅在VHL干预后，RSA测试第二部分的成绩更好，且该测试的疲劳指数更低（5.18%[1.3%]对7.72%[1.6%]；P<.01）。VHL组在YYIR1中的成绩也更好（1468[313]米对1111[248]米；P<.01），而正常呼吸条件组没有变化。
本研究表明，进行VHL下的高强度循环训练可以提高RSA，并可能提高跑步耐力表现。另一方面，这种方法似乎不会给无氧运动表现带来可转移的益处。
