UNLABELLED
Firefighters are at an elevated risk for cardiometabolic disease and sudden cardiac death due to physiological and psychological stressors. Research suggests time restricted feeding (TRF) may improve health and performance variables.
OBJECTIVE
This study investigated the effects of a 7-week TRF (14-hour fasting:10-hour eating window) on fitness variables related to physical health and performance among professional, resistance-trained firefighters.
METHODS
Several fitness variables were assessed pre- and post-TRF intervention.
RESULTS
Relative and absolute ventilatory threshold (VT) increased (P < 0.05), relative and absolute , decreased (P < 0.05), and muscular strength, endurance, and power were not affected pre- versus post-intervention.
CONCLUSION
Although , decreased, all other performance variables were not negatively impacted by TRF. Improvements in VT may be associated with improvements to markers of endurance exercise performance in firefighters, but more data are needed to confirm this hypothesis.
目的
本研究旨在探究限时进食（TRF，14 小时禁食：10 小时进食窗口）对专业、抗阻训练的消防员身体健康和体能相关的各项体能指标的影响。
方法
在 TRF 干预前后，对多项体能指标进行了评估。
结果
相对和绝对通气阈（VT）提高（P<0.05），相对和绝对 降低（P<0.05），而肌肉力量、耐力和功率在干预前后没有变化。
结论
尽管 降低，但 TRF 并未对所有其他运动表现指标产生负面影响。VT 的改善可能与消防员耐力运动表现指标的改善有关，但需要更多数据来证实这一假设。
