High-intensity circuit training (HICT) using body weight as resistance is a popular fitness trend and an ideal exercise modality in terms of functionality and economy. Given the popularity of HICT, evidence suggests that sex may elicit unique physiological and perceptual responses to this mode of exercise and there is a need for further work in this area. The purpose of this study was to examine physiological and perceptual responses of females and males to HICT using body weight resistance exercise. Forty-five participants (23 females and 22 males) completed baseline testing and a 15-minute HICT exercise bout wearing a portable metabolic analyzer. %VO, %HR, and RER were monitored during exercise and analyzed at 3 different 5-minute time segments during the HICT (beginning, middle, end). RPE was assessed half-way through the circuit (7.5), immediately upon cessation of exercise (15), and 15-minutes post-exercise (Session RPE). There was a significant (<0.01) time effect on %VO, %HR, RER, and RPE. At all three time points, %VO was significantly (<0.02) higher among females compared to males. RER values were significantly (=0.02) higher among females during the last 5-minute segment (i.e. the end) of the exercise bout. However there were no differences in %HR (>0.20). Males reported a higher RPE immediately post-exercise compared to females (=0.01). Taken together, these data suggest that there are distinct, sex-specific physiological and perceptual responses to HICT; thus, sex-specific exercise prescription considerations are warranted.
以体重为阻力的高强度循环训练（HICT）是一种流行的健身趋势，在功能性和经济性方面是一种理想的运动方式。鉴于HICT的流行，有证据表明性别可能对这种运动方式产生独特的生理和感知反应，因此该领域需要进一步的研究。本研究的目的是检查女性和男性对使用体重阻力运动的HICT的生理和感知反应。45名参与者（23名女性和22名男性）完成了基线测试，并佩戴便携式代谢分析仪进行了15分钟的HICT运动。在运动期间监测%VO、%HR和RER，并在HICT的3个不同的5分钟时间段（开始、中间、结束）进行分析。在循环训练进行到一半时（7.5）、运动结束后立即（15）以及运动后15分钟（训练后RPE）评估主观用力程度（RPE）。%VO、%HR、RER和RPE存在显著（<0.01）的时间效应。在所有三个时间点上,女性的%VO显著（<0.02）高于男性。在运动的最后5分钟时间段（即结束时），女性的RER值显著（=0.02）更高。然而，%HR没有差异（>0.20）。与女性相比，男性在运动后立即报告的主观用力程度更高（=0.01）。综上所述，这些数据表明对HICT存在明显的、性别特异性的生理和感知反应；因此，有必要考虑针对性别的运动处方。
