The aim of the study was to investigate the effect of an inspiratory muscle warm-up on the VO2 kinetics during submaximal intensity ergometer rowing. Ten competitive male rowers (age 23.1 ± 3.8 years; height 188.1 ± 6.3 cm; body mass 85.6 ± 6.6 kg) took part in this investigation. A submaximal constant intensity (90% PVO2max) rowing test to volitional exhaustion was carried out twice with the standard rowing warm-up (Test 1) and with the standard rowing warm-up with additional specific inspiratory muscle warm-up of two sets of 30 repetitions at 40% maximal inspiratory pressure (Test 2). We found a significant correlation between time constant (τ1) and the VO2 value at 400 s in Test 1 (r = 0.78; p < 0.05); however, no correlation was found between those parameters in Test 2. In addition, we found a positive association between VO2max from the incremental rowing test and τ1 from Test 1 (r = 0.71; p < 0.05), whereas VO2 did not correlate with τ1 from Test 2. Adding inspiratory muscle warm-up of 40% maximal inspiratory pressure to regular rowing warm-up had no significant effect on oxygen consumption kinetics during submaximal rowing tests.

次最大划船过程中吸气肌肉热身对VO2动力学的影响
该研究的目的是研究次最大强度测功仪划船过程中吸气肌肉热身对VO 2动力学的影响。十名有竞争力的男性赛艇运动员(年龄23.1±3.8岁;身高188.1±6.3厘米;体重85.6±6.6公斤)参加了这项调查。在标准划船热身(测试1)和标准划船热身以及两组额外的特定吸气肌肉热身下,进行了2次次最大恒定强度(90%P VO2max)划船试验,以进行自愿性疲劳在最大吸气压力为40%时进行30次重复(测试2)。我们发现时间常数(之间的相关性显著τ 1)和VO 2在400秒值在试验1(R = 0.78; p<0.05); 然而,没有相关性被发现在试验2的那些参数之间。另外,我们发现VO之间的正关联2MAX由增量划船测试和τ 1从试验1(R = 0.71; p <0.05),而VO 2没与相关成分τ 1从测试2.添加吸气肌热身的40%,最大吸气压力正规赛艇热身期间曾亚最大赛艇测试对氧的消耗动力学无显著影响。
