The aim of the study was to investigate the effects of a partial sleep deprivation on a subsequent supramaximal exercise evaluated from the 30 second Wingate test, and on the following recovery. To take into account the active muscle mass, the Wingate test was performed against a constant braking force related to the data of a force-velocity test conducted on a Monark cycle ergometer (Model 814 E with weights) one week before the experimental test. Eight highly trained athletes were enrolled for this study. The changes in ventilatory and metabolic responses were analyzed during and upon completion of physical 30 second exercise, taking place after two nights, in other words, after a reference night and after a night with reduced sleep. Partial sleep deprivation was obtained by delaying bedtime until 3 a.m. The 30 second Wingate test was performed between 9 a.m. and noon the following days, using a Monark ergometer (Model 814 F). The analyses of change scores disclosed that there were no main significant effects for measures of ventilation, lactates and pH(v) levels under the two experimental conditions. The peak power, the mean power output and the peak velocity recorded after partial sleep deprivation were not modified in comparison with the values obtained after the reference night. These findings suggest that acute sleep loss did not contribute to alterations in supramaximal exercise.
本研究的目的是调查部分睡眠剥夺对随后通过30秒温盖特测试评估的超最大运动以及对随后恢复的影响。为了考虑主动肌肉质量，在实验测试前一周，在Monark自行车测力计（型号814 E带砝码）上进行力-速度测试，根据测试数据设置恒定制动力，在此制动力下进行温盖特测试。本研究招募了八名训练有素的运动员。在两个夜晚后，即一个参照夜晚和一个睡眠减少的夜晚后，在30秒体育锻炼期间及结束后，分析通气和代谢反应的变化。通过将就寝时间推迟到凌晨3点来实现部分睡眠剥夺。在接下来几天上午9点到中午之间，使用Monark测力计（型号814 F）进行30秒温盖特测试。变化分数分析表明，在两种实验条件下，通气、乳酸和pH（v）水平测量值没有主要显著影响。与参照夜晚后获得的值相比，部分睡眠剥夺后记录的峰值功率、平均功率输出和峰值速度没有改变。这些发现表明，急性睡眠不足不会导致超最大运动的改变。
