We sought to determine the effects of substituting parts of aerobic training (AT) by resistance training (RT) on metabolic syndrome (MetS) factors. MetS patients (aged 56 ± 7 years; body mass index 33 ± 5 kg·m−2 and 3.9 ± 0.8 MetS factors) were randomized to undergo 1 of the following isocaloric, 16-week long exercise programs: (i) cycling 4 bouts of 4-min at 90% of maximal heart rate (HRmax) followed by 3 sets of 12 repetitions of 3 lower limb free-weight exercises (high-intensity interval training (HIIT)+RT group; n = 33), (ii) cycling 5 bouts of 4 min at 90% of HRmax (HIIT+HIIT group; n = 33), or (iii) no exercise control group (n = 21). We measured the evolution of all 5 MetS components (z score), cardiorespiratory fitness (maximal oxygen uptake), leg strength and power (leg press 1-repetition maximum (1RM) and countermovement jump (CMJ)), fasting blood glucose (FG), fasting insulin, and insulin resistance (homeostasis model assessment 2). Both training groups improved maximal oxygen uptake similarly (170 ± 310 and 190 ± 210 mL O2·min−1; P < 0.001) and z score (−0.12 ± 0.29 and −0.12 ± 0.31 for HIIT+RT and HIIT+HIIT, respectively; P < 0.02). However, only HIIT+RT improved CMJ (P = 0.002) and leg press 1RM above the HIIT+HIIT group (21% vs 6%; P < 0.001). Furthermore, FG only decreased in the HIIT+RT group (5%; P = 0.026, time × group). Our findings suggest that substitution of part of HIIT by leg RT improves glucose control in MetS individuals. Novelty Most studies addressing the efficacy of endurance versus resistance training are not matched by energy expenditure. We found that substituting 20% of AT with RT reduces hyperglycemia in MetS individuals. Training recommendations to regain glycemic control in MetS individuals should include resistance training.

我们试图确定通过阻力训练 (RT) 替代部分有氧训练 (AT) 对代谢综合征 (MetS) 因素的影响。MetS 患者（年龄 56 ± 7 岁；体重指数 33 ± 5 kg·m-2 和 3.9 ± 0.8 MetS 因素）随机接受以下等热量的 16 周长锻炼计划之一：(i) 骑自行车 4 次以 90% 的最大心率 (HRmax) 进行 4 分钟，然后进行 3 组 12 次重复的 3 次下肢自由重量练习（高强度间歇训练 (HIIT)+RT 组；n = 33），(ii)以 90% 的 HRmax（HIIT+HIIT 组；n = 33）或 (iii) 无运动对照组（n = 21）骑自行车 5 次，每次 4 分钟。我们测量了所有 5 个 MetS 组件（z 分数）、心肺适能（最大摄氧量）、腿部力量和力量（腿部推举 1-重复最大次数 (1RM) 和反向跳跃 (CMJ)）的演变，空腹血糖 (FG)、空腹胰岛素和胰岛素抵抗（稳态模型评估 2）。两个训练组都类似地提高了最大摄氧量（170 ± 310 和 190 ± 210 mL O2·min-1；P < 0.001）和 z 分数（HIIT+RT 和 HIIT+HIIT 分别为 -0.12 ± 0.29 和 -0.12 ± 0.31） ; P < 0.02)。然而，只有 HIIT+RT 改善了 CMJ（P = 0.002）和比 HIIT+HIIT 组高 1RM 的腿举（21% vs 6%；P < 0.001）。此外，FG 仅在 HIIT+RT 组中下降（5%；P = 0.026，时间 × 组）。我们的研究结果表明，腿部放疗替代部分 HIIT 可改善 MetS 个体的血糖控制。新颖性 大多数关于耐力训练与阻力训练效果的研究都与能量消耗不匹配。我们发现用 RT 替代 20% 的 AT 可降低 MetS 个体的高血糖症。
