INTRODUCTION: Hypoxia-induced hyperventilation is an effect of acute altitude exposure, which may lead to respiratory muscle fatigue and secondary locomotor muscle fatigue. The purpose of this study was to determine if resistive and/or endurance respiratory muscle training (RRMT and ERMT, respectively) vs. placebo respiratory muscle training (PRMT) improve cycling performance at altitude.METHODS: There were 24 subjects who were assigned to PRMT (N 8), RRMT (N 8), or ERMT (N 8). Subjects cycled to exhaustion in a hypobaric chamber decompressed to 3657 m (12,000 ft) at an intensity of 55% sea level maximal oxygen consumption (Vo2max) before and after respiratory muscle training (RMT). Additionally, subjects completed a Vo2max, pulmonary function, and respiratory endurance test (RET) before and after RMT. All RMT protocols consisted of three 30-min training sessions per week for 4 wk.RESULTS: The RRMT group increased maximum inspiratory (PImax) and expiratory (PEmax) mouth pressure after RMT (PImax: 117.7 11.6 vs. 162.6 20.0; PEmax: 164.0 33.2 vs. 216.5 44.1 cmH2O). The ERMT group increased RET after RMT (5.2 5.2 vs.18.6 16.9 min). RMT did not improve Vo2max in any group. Both RRMT and ERMT groups increased cycling time to exhaustion (RRMT: 35.9 17.2 vs. 45.6 22.2 min and ERMT: 33.8 9.6 vs. 42.9 27.0 min).CONCLUSION: Despite different improvements in pulmonary function, 4 wk of RRMT and ERMT both improved cycle time to exhaustion at altitude.Wheelock CE, Hess HW, Johnson BD, Schlader ZJ, Clemency BM, St. James E, Hostler D.

Improve Exercise Performance

Respiratory muscle training (RMT) has been proposed as an effective means to increase the strength of the inspiratory muscles and improve exercise performance. The purpose of this study was to examine the effect of RMT on cycling time to exhaustion (TTE) and to determine any potential sex effect. We hypothesized that RMT would improve maximal inspiratory pressure (MIP) and TTE to a similar degreee in men and women. Males (n = 7; mean (± SD) age, 22.1 ± 1.5 y) and females (n = 8; mean (± SD) 24.5 ± 4.9 y) performed an incremental cycle test to determine maximal oxygen consumption ([Formula: see text]O2 max) (day 1), followed by a familiarization TTE (day 2) and baseline TTE (day 3) at 80% maximal work achieved during the [Formula: see text]O2 max test. Subjects then completed 5 weeks of respiratory muscle training (RMT) (5 d/week, 2 sets of 30 inspirations against 50% MIP). Four training sessions per week were performed at home and the 5th was supervised, during which the threshold load was increased if necessary. Following RMT, subjects completed 2 TTE tests (days 4 and 5). MIP increased in each subject (37% ± 18%, P < 0.05). There was no difference between men (pre = -100 ± 20 vs. post = -140 ± 29 cmH2O) and women (pre = -90 ± 28 vs. post = -117 ± 28 cmH2O). Baseline TTE (male = 301 ± 122 s; female = 338 ± 98 s) was shorter in comparison with the best of the 2 TTE-post tests (male = 353 ± 68 s; female = 416 ± 116 s; P < 0.01), but not when compared with days 4 or 5 (P > 0.05). RMT increases MIP and may improve exercise performance; however, improvements are variable with no differences between men and women.Key words: constant-intensity exercise, dyspnea, factors limiting exercise, maximal inspiratory pressure, respiratory muscles.

Chronic obstructive lung disease (COPD) is a chronic lung pathology that leads to respiratory muscle weakness and decreased function capacity. Patients need to have pulmonary rehabilitation to increase respiratory muscle strength. The aim of the study was to assess the effect of artificial respiratory muscle training (ARMT) on respiratory muscle function and exercise performance in chronic obstructive pulmonary disease (COPD). Thirty patients in the mild to moderate COPD stage were randomly classified into an ARMT (n = 10), a control group (n = 10), and a standard respiratory muscle training group (SRMT; n = 10) by following the blind procedure. The control group received no training. The training groups, however, were trained at home for 30 min per day, every day, for 6 weeks. The measurement analyses included spirometry, an inspiratory muscle strength examination, and an exercise performance test. Exercise performance was evaluated by a 6 min walk test (SWT). The results showed that the maximal inspiratory pressure (PImax) and the maximal expiratory pressure (PEmax) were observed to have significantly increased in both the ARMT group and the SRMT group compared with the control group (p < 0.05). Moreover, the ARMT group was found to have significantly increased the 6 min walking distance in comparison with the control group. However, the ARMT group and the SRMT group did not differ significantly in those parameters. We conclude that it would be possible for the ARMT group among COPD patients to have improved respiratory muscle strength and increased capacity to walk.
