DataSheet1_Effect of 12 weeks of complex training on occupational activities, strength, and power in professional firefighters.docx

Objective: This study examined the effects of 12-week complex training (CT) programs on professional firefighters’ occupational activities, strength, and power.
Methods: Thirty men professional firefighters were randomly assigned to the CT group (n = 15) and control group (n = 15). The CT group performed complex training and the control group completed resistance training (RT) twice a week over 12 weeks. The occupational activities, strength, and power were assessed at baseline and immediately after the intervention by measuring the performance of 100 m load-bearing run (100 m LR), 60 m shoulder ladder run (60 m SLR), 5 m × 20 m shuttle run (5 m × 20 m SR), 4th-floor climbing rope (4th-floor CR), countermovement jump with arm swing (CMJas), seated medicine-ball throw (SMT), one-repetition maximum bench press (1RM BP), and one-repetition maximum back squat (1RM BS).
Results: The results showed that compared to RT, CT induced significantly greater improvements in 60 m SLR (p = 0.007), 4th-floor CR (p = 0.020), CMJas (p = 0.001), and SMT (p < 0.001).
Conclusion: These findings suggest that CT is a novel intervention with great promise of improving professional firefighters’ occupational activities, strength, and power.

研究目标：本研究探讨了为期12周的复合训练（Complex Training，CT）方案对职业消防员职业作业能力、肌肉力量与爆发力的影响。
研究方法：招募30名男性职业消防员，采用随机分组方式将其分为复合训练组（n=15）与对照组（n=15）。12周干预周期内，复合训练组每周开展2次复合训练，对照组则每周完成2次抗阻训练（Resistance Training，RT）。分别于干预前（基线水平）及干预结束后即刻，对受试者的职业作业能力、肌肉力量与爆发力进行评估，测试项目包括：100米负重跑（100 m load-bearing run，100 m LR）、60米梯式肩扛跑（60 m shoulder ladder run，60 m SLR）、5米×20米折返跑（5 m × 20 m shuttle run，5 m × 20 m SR）、四楼爬绳测试（4th-floor climbing rope，4th-floor CR）、摆臂反向纵跳（countermovement jump with arm swing，CMJas）、坐姿药球抛投（seated medicine-ball throw，SMT）、卧推一次最大重量（one-repetition maximum bench press，1RM BP）以及后蹲一次最大重量（one-repetition maximum back squat，1RM BS）。
研究结果：相较于抗阻训练，复合训练可使受试者在60米梯式肩扛跑（p=0.007）、四楼爬绳测试（p=0.020）、摆臂反向纵跳（p=0.001）以及坐姿药球抛投（p<0.001）这几项指标上获得更为显著的性能提升。
研究结论：上述研究结果表明，复合训练是一种极具应用潜力的新型干预手段，有望有效改善职业消防员的职业作业能力、肌肉力量与爆发力。
