High-Intensity Functional Training (HIFT) is a novel exercise intervention that may test body systems in a balanced and integrated fashion by challenging individuals' abilities to complete mechanical work. However, research has not previously determined if physical work capacity is unique to traditional physiologic measures of fitness. Twenty-five healthy men and women completed a six-week HIFT intervention with physical work capacity and various physiologic measures of fitness assessed pre- and post-intervention. At baseline, these physiologic measures of fitness (e.g., aerobic capacity) were significantly associated with physical work capacity and this relationship was even stronger at post-intervention assessment. Further, there were significant improvements across these physiologic measures in response to the delivered intervention. However, the change in these physiologic measures failed to predict the change in physical work capacity induced via HIFT. These findings point to the potential utility of HIFT as a unique challenge to individuals' physiology beyond traditional resistance or aerobic training. Elucidating the translational impact of increasing work capacity via HIFT may be of great interest to health and fitness practitioners ranging from strength/conditioning coaches to physical therapists.
高强度功能性训练（HIFT）是一种新型运动干预方式，它通过挑战个体完成机械工作的能力，以平衡且综合的方式测试身体系统。然而，此前的研究尚未确定身体工作能力是否独立于传统的生理健康指标。25名健康男性和女性完成了为期六周的HIFT干预，并在干预前后评估了身体工作能力和各种生理健康指标。在基线时，这些生理健康指标（如有氧能力）与身体工作能力显著相关，且这种关系在干预后评估时更强。此外，针对所实施的干预，这些生理指标有显著改善。然而，这些生理指标的变化未能预测通过HIFT诱导的身体工作能力的变化。这些发现表明，HIFT作为一种对个体生理机能的独特挑战，其潜在效用超越了传统的阻力训练或有氧训练。对于从力量/体能教练到物理治疗师等各类健康与健身从业者而言，阐明通过HIFT提高工作能力的转化影响可能具有极大的吸引力。
