摘要

超重或肥胖的人更喜欢高强度间歇训练(HIIT),因为它既省时又愉悦。然而,高强度间歇训练会导致延迟性肌肉酸痛(DOMS)。本研究旨在调查欧米伽-3补充剂对未经训练的超重或肥胖男性在骑自行车HIIT运动中诱发的肌肉酸痛、肌肉损伤和急性炎症指标的影响。本研究采用了随机、双盲的研究方法。24 名久坐不动的男性被随机分配接受欧米伽-3(O3)(4 克鱼油)或安慰剂(Con)。受试者连续 4 周服用鱼油胶囊,并在第 4 周进行骑自行车 HIIT 训练。干预4周后,O3组的欧米伽-3指数比基线增加了52.51%。所有受试者均在第四周进行了 HIIT 运动。HIIT 48 小时后,Con 组的血浆肌酸激酶(CK)水平持续上升。而 O3 组的肌酸激酶水平仅在 HIIT 后立即和 24 小时内上升,在 HIIT 后 48 小时内下降。Con 组的白细胞计数(WBC)在 HIIT 后立即增加,而 O3 组则没有增加。两组的 CRP 均无变化。与 Con 组相比,O3 组的小腿疼痛评分降低幅度更大。O3 组的腿部力量恢复速度也快于 Con 组。连续4周补充Omega-3可降低CK水平的升高,减少小腿疼痛评分,恢复腿部力量,减少骑车HIIT后的DOMS指标。

Effects of Omega-3 Supplementation on the Delayed Onset Muscle Soreness after Cycling High Intensity Interval Training in Overweight or Obese Males
People with overweight or obesity preferred high-intensity interval training (HIIT) due to the time-efficiency and pleasure. However, HIIT leads to delayed onset muscle soreness (DOMS). The present study aimed to investigate the effects of omega-3 supplementation on DOMS, muscle damage, and acute inflammatory markers induced by cycling HIIT in untrained males with overweight or obesity. A randomized, double-blinded study was used in the present study. Twenty-four males with a sedentary lifestyle were randomly assigned to either receive omega-3 (O3) (4 g fish oil) or placebo (Con). Subjects consumed the capsules for 4 weeks and performed cycling HIIT at the 4th week. After 4 weeks-intervention, the omega-3 index of O3 group increased by 52.51% compared to the baseline. All subjects performed HIIT at 4th week. The plasma creatine kinase (CK) level of Con group increased throughout 48h after HIIT. While the CK level of O3 group increased only immediately and 24h after HIIT and decreased at 48h after HIIT. The white blood cell count (WBC) of Con group increased immediately after the HIIT, while O3 group did not show such increase. There was no change of CRP in both groups. O3 group had a higher reduction of calf pain score compared to Con group. O3 group also showed a recovery of leg strength faster than Con group. Omega-3 supplementation for 4 weeks lower increased CK level, reduced calf pain score, and recovery leg strength, DOMS markers after cycling HIIT.
