背景：阻力训练是竞技和休闲运动员的常见锻炼形式。增强阻力训练的恢复可能会改善肌肉重塑过程，刺激更快地恢复到巅峰表现。目的：探讨神经肌肉电刺激 (NMES) 和冷水浸泡 (CWI) 两种不同的恢复方式对运动表现以及生化和超声检查指标的影响。参与者：30 名接受阻力训练的男性（23.1 +/- 2.9 岁、175.2 +/- 7.1 厘米、82.1 +/- 8.4 公斤）被随机分配至 NMES、CWI 或对照组 (CON)。设计和设置：所有参与者在第 1 天完成了大容量下半身阻力训练锻炼，并在锻炼后 24 (24H) 和 48 h (48H) 返回人体表现实验室进行后续测试。措施：在运动前 (PRE) 和运动后立即 (IP)、30 分钟 (30P)、24 小时 (24H) 和 48 小时 (48H) 采集血样。检查受试者在深蹲运动中的表现变化（总重复次数和每次重复的平均功率）、炎症生物标志物以及股直肌（RF）和股外侧肌的横截面积和回声强度（EI）的变化。结果：重复次数没有观察到组间差异（P = .250；功效：P = .663）。基于推论的分析表明，与 CON 相比，CWI 后 C 反应蛋白浓度的增加可能更大，而从 IP 到 24 小时，NMES 可能比 CON 下降更多。 IP 和 30P 之间白细胞介素 10 浓度的增加可能在 CWI 中比 NMES 更大，但与 CON 没有不同。基于推理的 RF EI 分析表明，IP 和 48H 之间的 CWI 可能会下降。在任何其他肌肉结构测量中均未发现组间存在其他差异。结论：结果表明，CWI 诱导促炎和抗炎标记物更大程度增加，同时降低 RF EI，这表明 CWI 可能有效增强大容量抗阻运动后的短期肌肉恢复。
Context: Resistance training is a common form of exercise for competitive and recreational athletes. Enhancing recovery from resistance training may improve the muscle-remodeling processes, stimulating a faster return to peak performance. Objective: To examine the effects of 2 different recovery modalities, neuromuscular electrical stimulation (NMES) and cold-water immersion (CWI), on performance and biochemical and ultrasonographic measures. Participants: Thirty resistance-trained men (23.1 +/- 2.9 y, 175.2 +/- 7.1 cm, 82.1 +/- 8.4 kg) were randomly assigned to NMES, CWI, or control (CON). Design and Setting: All participants completed a high-volume lower-body resistance-training workout on d 1 and returned to the human performance laboratory 24 (24H) and 48 h (48H) postexercise for follow-up testing. Measures: Blood samples were obtained preexercise (PRE) and immediately (IP), 30 min (30P), 24 h (24H), and 48 h (48H) post. Subjects were examined for performance changes in the squat exercise (total repetitions and average power per repetition), biomarkers of inflammation, and changes in cross-sectional area and echo intensity (EI) of the rectus femoris (RF) and vastus lateralis muscles. Results: No differences between groups were observed in the number of repetitions (P = .250; power: P = .663). Inferential-based analysis indicated that increases in C-reactive protein concentrations were likely increased by a greater magnitude after CWI compared with CON, while NMES possibly decreased more than CON from IP to 24H. Increases in interleukin-10 concentrations between IP and 30P were likely greater in CWI than NMES but not different from CON. Inferential-based analysis of RF EI indicated a likely decrease for CWI between IP and 48H. No other differences between groups were noted in any other muscle-architecture measures. Conclusions: Results indicated that CWI induced greater increases in pro- and anti-inflammatory markers, while decreasing RF EI, suggesting that CWI may be effective in enhancing short-term muscle recovery after high-volume bouts of resistance exercise.
