Abstract

UNLABELLED

Special force units and military personnel undergo demanding physical exercise and might benefit from high-intensity respiratory muscle training (RMT) by increasing their endurance performance. This study examined the effects of a 6-week high-intensity RMT on running performance and oxygen uptake (VO2max) in a group of German Special Force Squad members.

METHODS

17 participants were randomly assigned to a training or control group. Baseline and post-testing included a ramp test, as well as an incremental test on a treadmill, performed to physical exhaustion. VO2, respiratory exchange ratio, and heart rate were measured breath by breath. Furthermore, maximum running speed (V(max)), 4 mmol x 1(-1) lactate threshold (V4) and perception of respiratory effort were determined. During pulmonary testing, sustained maximum inspiratory and expiratory pressure (PI(max) and PE(max)) were obtained. RMT was performed daily at approximately 90% PI(max) for 6 weeks with 2 x 30 breath cycles using an Ultrabreathe lung trainer.

RESULTS

No statistical differences were detected between the groups for any parameter after RMT.

CONCLUSION

High-intensity RMT did not show any benefits on VO2max and endurance performance and are unlikely to be of benefit to military or paramilitary training programs for an increase in endurance performance.

摘要

未标注

特种部队和军事人员进行高强度体育锻炼，通过提高耐力表现，他们可能会从高强度呼吸肌训练（RMT）中受益。本研究调查了为期6周的高强度RMT对一组德国特种部队队员跑步表现和摄氧量（最大摄氧量）的影响。

方法

17名参与者被随机分配到训练组或对照组。基线测试和测试后包括一次斜坡测试，以及在跑步机上进行的递增测试，直至身体疲惫。逐次测量摄氧量、呼吸交换率和心率。此外，还测定了最大跑步速度（V(max)）、4 mmol x 1(-1)乳酸阈（V4）和呼吸努力感知。在肺部测试期间，获得持续最大吸气和呼气压力（PI(max)和PE(max)）。使用Ultrabreathe肺训练器，每天以约90%PI(max)进行RMT，持续6周，每次2×30个呼吸周期。
