Strongman training (ST) has become an increasingly popular modality, but data on physiological responses are limited. This study sought to determine physiological responses to an ST session compared to a traditional strength exercise training (RST) session. Ten healthy men (23.6 ± 27.5 years, 85.8 ± 10.3 kg) volunteered in a crossover design, where all participants performed an ST session, an RST session, and a resting session within 7 days apart. The ST consisted of sled drag, farmer's walk, 1 arm dumbbell clean and press, and tire flip at loads eliciting approximately 30 seconds of near maximal effort per set. The RST consisted of squat, deadlift, bench press, and power clean, progressing to 75% of 1 repetition maximum. Sessions were equated for approximate total set duration. Blood lactate and salivary testosterone were recorded immediately before and after training sessions. Heart rate, caloric expenditure, and substrate utilization were measured throughout the resting session, both training protocols and for 80 minutes after training sessions. Analyses were conducted to determine differences in physiological responses within and between protocols. No significant changes in testosterone occurred at any time point for either session. Lactate increased significantly immediately after both sessions. Heart rate, caloric expenditure, and substrate utilization were all elevated significantly during ST and RST. Heart rate and fat expenditure were significantly elevated compared to resting in both sessions' recovery periods; calorie and carbohydrate expenditures were not. Compared to RST, ST represents an equivalent physiological stimulus on key parameters indicative of potential training-induced adaptive responses. Such adaptations could conceivably include cardiovascular conditioning.
壮汉训练（ST）已成为一种越来越受欢迎的训练方式，但有关生理反应的数据有限。本研究旨在确定与传统力量训练（RST）课程相比，ST课程的生理反应。10名健康男性（23.6±27.5岁，85.8±10.3千克）自愿参与交叉设计，所有参与者在相隔7天内分别进行一次ST课程、一次RST课程和一次休息课程。ST包括雪橇拖拽、农夫行走、单臂哑铃抓举和推举以及轮胎翻转，每组负荷能引发约30秒的接近最大努力。RST包括深蹲、硬拉、卧推和高翻，逐渐增加到1次重复最大值的75%。各课程的总组数持续时间大致相等。在训练课程前后立即记录血乳酸和唾液睾酮水平。在休息课程、两种训练方案期间以及训练课程后80分钟测量心率、热量消耗和底物利用情况。进行分析以确定不同方案内和方案间生理反应的差异。两种课程在任何时间点的睾酮水平均无显著变化。两次课程后血乳酸均显著增加。在ST和RST期间，心率、热量消耗和底物利用均显著升高。在两个课程的恢复期，与休息相比，心率和脂肪消耗均显著升高；热量和碳水化合物消耗则没有。与RST相比，ST对指示潜在训练诱导适应性反应的关键参数具有同等的生理刺激作用。可以想象，这种适应性变化可能包括心血管调节。
