本研究的目的是阐明补充牛磺酸对健康年轻男性高强度离心运动（ECC）后迟发性肌肉酸痛（DOMS）和肌肉损伤的影响。招募了29名健康的年轻男性，并以双盲方式随机分配接受安慰剂（n = 14）或牛磺酸补充剂（n = 15）。参与者在高强度ECC前2周和高强度ECC后3天，每天三次摄入2.0 g安慰剂或牛磺酸补充剂。开始补充两周后，参与者在Biodex等速测力仪上进行了两组单侧肘关节屈肌最大努力ECC。每组包括20次收缩，每次收缩持续3秒，每9秒重复一次，两组之间休息4分钟。在运动前和ECC后4天测量肌肉损伤参数，包括血清肌红蛋白（Mb）和肌酸激酶（CK）水平（以视觉模拟量表评估）、上臂围度（CIR）、肘关节活动范围（ROM）。与安慰剂组相比，牛磺酸组在ECC后2天DOMS的严重程度显著降低。在牛磺酸组，迟发性肌肉酸痛曲线下的面积也明显更小。然而，补充牛磺酸对ECC后的肌肉损伤（CIR、ROM、血清Mb水平和CK活性）没有影响。这些结果表明，补充牛磺酸可以有效地减少年轻健康男性在高强度ECC后的DOMS。
The purpose of the present study was to clarify the effects of taurine supplementation on delayed onset muscle soreness (DOMS) and muscle damage after high-intensity eccentric exercise (ECC) in healthy young men. Twenty-nine healthy young men were recruited and randomly assigned to receive either placebo (n = 14) or taurine supplementation (n = 15) in a double-blind manner. Participants ingested either 2.0 g of placebo or taurine supplement three times a day for 2 weeks before and 3 days after high-intensity ECC. Two weeks after starting supplementation, participants performed two sets of unilateral maximal-effort ECC of the elbow flexors on a Biodex isokinetic dynamometer. Each set consisted of 20 contractions with each contraction lasting 3 s and repeated every 9 s, and a 4 min period of rest in between sets. DOMS (evaluated by the visual analogue scale), upper arm circumference (CIR), elbow range of motion (ROM), and parameters of muscle damage including serum myoglobin (Mb) and creatine kinase (CK) levels, were measured before exercise and for 4 days after ECC. The severity of DOMS 2 days after ECC was significantly less in the taurine group than in the placebo group. The area under the curve for DOMS was also significantly smaller in the taurine group. However, taurine supplementation did not affect muscle damage (CIR, ROM, and serum Mb level and CK activity) after ECC. These results suggest that taurine supplementation effectively decreases DOMS after high-intensity ECC in young healthy men.
