Aerobic dance (AD) is an appropriate physical activity for improving cardiorespiratory fitness. This study aimed to compare cardiorespiratory and metabolic responses, and muscle fatigue between an air dissipation platform (ADP) and a hard surface during a video-recorded AD session.
25 healthy young women (23.3 ± 2.5 years) completed three sessions. In session 1, participants performed an incremental test to exhaustion on a treadmill. One week after session 1, participants were randomly assigned in a crossover design to perform video-recorded AD sessions on an ADP and on a hard surface (sessions 2 and 3). Cardiorespiratory and metabolic responses were assessed during AD sessions. Muscular fatigue was measured before and after AD sessions by a countermovement jump test.
Significantly higher heart rate, respiratory exchange ratio, pulmonary ventilation, ventilatory oxygen equivalent, and ventilatory carbon dioxide equivalent were observed on an ADP than on a hard surface ( < 0.05). Despite a significant increase in lactate levels on an ADP ( ≤ 0.01), muscular fatigue and perceived exertion rating were similar on both surfaces ( > 0.05).
Video-recorded AD on an ADP increased the cardioventilatory and metabolic responses compared to a hard surface, preventing further muscle fatigue.
有氧舞蹈(AD)是一种改善心肺适能的适宜体力活动。本研究旨在比较在空气耗散平台(ADP)和硬表面上进行视频记录的 AD 期间的心肺和代谢反应以及肌肉疲劳。
25 名健康年轻女性(23.3 ± 2.5 岁)完成了三项测试。在第 1 项测试中,参与者在跑步机上进行了直至力竭的递增测试。在第 1 项测试后一周,参与者以交叉设计随机分配在 ADP 和硬表面(第 2 项和第 3 项测试)上进行视频记录的 AD 测试。在 AD 测试期间评估心肺和代谢反应。通过反跳式纵跳测试,在 AD 测试前后测量肌肉疲劳。
ADP 上的心率、呼吸交换比、肺通气量、通气氧当量和通气二氧化碳当量明显高于硬表面( < 0.05)。尽管 ADP 上的乳酸水平显著增加( ≤ 0.01),但两种表面上的肌肉疲劳和感知用力等级相似( > 0.05)。
与硬表面相比,ADP 上的视频记录的 AD 增加了心肺和代谢反应,防止了进一步的肌肉疲劳。
