Abstract

This study aimed to evaluate mechanical and physiological responses to all-out high-intensity interval training (HIIT) sessions (10 maximal efforts of 30 seconds each with 4 min of rest) performed against different resistance forces on a one-leg knee extension ergometer. Eighteen men conducted an incremental test to determine the resistance associated with its maximal power (R_max), followed by all-out HIIT sessions at 120%, 160%, and 200% of R_max, while oxygen consumption and neuromuscular function were measured. Mechanical power output was higher during the session at 200% of R_max compared to the other sessions (p < 0.001), but its absolute anaerobic energy contribution was similar to that at 160% of R_max. Notably, the all-out efforts at 200% R_max led to inconsistent kicking cadence and some participants were unable to complete the session. Therefore, 160% R_max was the highest suitable resistance force for a consistent all-out HIIT session on a knee extension ergometer.

单腿伸膝测力计上的全力间歇运动：对不同阻力的机械和生理反应。

本研究旨在评估全强度间歇训练（HIIT）（10次最大强度训练，每次30秒，休息4分钟）在单腿膝关节伸展力计上针对不同阻力进行的机械和生理反应。18名男性进行了一项增量测试，以确定与其最大功率（Rmax）相关的阻力，随后进行了120%，160%和200%的全力以赴HIIT训练，同时测量了氧气消耗和神经肌肉功能。与其他时段相比，在Rmax的200%时，机械功率输出更高（p max）。值得注意的是，200% Rmax的全力训练导致踢腿节奏不一致，一些参与者无法完成训练。因此，160% Rmax是在膝关节伸展力计上进行持续的全力以赴HIIT训练的最高合适阻力。

期刊介绍： Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives. The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
