Aerial fitness is quickly gaining popularity; however, little is known regarding the physiological demands of aerial athletes. The purpose of the study was to examine contralateral muscle imbalances, compare dominant versus non-dominant hamstrings-to-quadriceps (H:Q) ratios, and to establish a physiological profile of recreational aerial athletes.
Thirteen aerialist women visited a local aerial studio to participate in a data collection session to examine isometric levels of upper and lower body strength, muscle endurance, flexibility, balance, and cardiovascular fitness.
No significant differences were found between dominant and non-dominant hand grip strength ( = 0.077), dominant and non-dominant isometric knee flexion ( = 0.483), dominant and non-dominant isometric knee extension ( = 0.152), or dominant and non-dominant isometric H:Q ratios ( = 0.102). In addition, no significant difference was found between isometric dominant H:Q ratio and the widely-used value of 0.60 ( = 0.139). However, isometric non-dominant H:Q ratio was significantly lower than the 0.60 criterion ( = 0.004). Aerial athletes demonstrated to have excellent flexibility, balance, cardiorespiratory fitness, and average strength.
Aerial fitness may be another recreational activity that could be used to maintain higher levels of flexibility, balance, cardiorespiratory fitness, and strength. Aerialists may want to consider focusing on strengthening the lower body and balancing the hamstrings and quadriceps muscle strength.
空中健身运动正迅速普及；然而，对于空中运动员的生理需求却知之甚少。本研究的目的是检查对侧肌肉失衡情况，比较优势侧与非优势侧的腘绳肌与股四头肌（H:Q）比率，并建立休闲空中运动员的生理特征。
13名女性空中运动员前往当地的空中工作室参加数据收集活动，以检查上下肢力量、肌肉耐力、柔韧性、平衡能力和心血管健康的等长水平。
优势侧与非优势侧握力（P = 0.077）、优势侧与非优势侧等长屈膝（P = 0.483）、优势侧与非优势侧等长伸膝（P = 0.152）或优势侧与非优势侧等长H:Q比率（P = 0.102）之间均未发现显著差异。此外，等长优势侧H:Q比率与广泛使用的0.60值之间也未发现显著差异（P = 0.139）。然而，等长非优势侧H:Q比率显著低于0.60的标准（P = 0.004）。空中运动员表现出具有出色的柔韧性、平衡能力、心肺功能和平均力量。
空中健身可能是另一项可用于维持较高水平的柔韧性、平衡能力、心肺功能和力量的休闲活动。空中运动员可能需要考虑着重加强下肢力量，并平衡腘绳肌和股四头肌的力量。
