| 为探究短期南极磷虾油补充对大强度抗阻训练后人体下肢肌肉运动能力恢复的影响，选取26名男子体能训练专项在校大学生，随机分为安慰剂（PL）组和南极磷虾油（AKO）组，各组分别在抗阻运动前7 d每天服用6 g大豆油或AKO，并在抗阻运动后持续每天服用至实验结束。抗阻运动方案为受试者先采用70% 1次重复最大力量（1RM）的质量完成8次×10组的负重深蹲，之后再以自身体质量完成20次×5组的深蹲跳，组间间歇3 min。受试者分别在抗阻运动前和运动后24、48、72 h完成等速肌力、垂直纵跳和20 m冲刺测试。结果表明：下肢力量耐力方面，两组受试者膝关节屈伸肌在240（°）/s等速测试下的总功无显著性差异（p>0.05）；下肢最大力量方面，与PL组相比，AKO组右膝关节屈伸肌在运动后72 h于60（°）/s等速测试下的最大功显著升高（p<005），左膝关节伸肌在运动后48 h显著升高（p<0.05），左膝关节屈肌在运动后48 h和72 h显著升高（p<0.05）；下肢爆发力方面，两组受试者垂直纵跳高度无显著性差异（p>0.05）；速度能力方面，两组受试者20 m冲刺所用时间无显著性差异（p>0.05）。综上，短期南极磷虾油补充可以促进大强度抗阻训练后下肢肌肉最大力量的恢复，对其他运动能力的恢复无显著影响。

| In order to investigate the effects of short-term Antarctic krill oil (AKO) supplementation on the recover of muscle motor ability of the human lower limbs after high-intensity resistance exercise, twenty-six male college students with special physical training were randomly divided into two groups: placebo (PL) group and AKO group. The PL group took 6 g soybean oil daily and the AKO group took the same dose of AKO for 7 d before the resistance exercise, and continued to take it until the end of the experiment. The resistance exercise scheme was as follows: the subjects were requested to complete 10 sets of 8 squats with 70% 1RM (one-repetition maximum), and the group interval was 3 min. After that, the subjects were requested to complete 5 sets of 20 bodyweight squat jumps, and the group interval was 3 min. Isokinetic muscle strength of the knee extensors and flexors, height of vertical jump, and 20-metre sprint were measured before resistance exercise and at 24, 48, 72 h after exercise. The results showed that in terms of lower limbs muscle endurance, there was no significant difference in the total work between AKO group and PL group at the speed of 240(°)/s (p>0.05); in terms of lower limbs muscle maximal strength, at the speed of 60(°)/s, the maximum work (MW) of the right knee extensors and flexors in AKO group, as well as the left knee flexors, were significantly higher than that in PL group after 72 h of exercise (p<0.05). After 48 h of exercise, the MW of the left knee extensors and flexors in AKO group were significantly higher than that in PL group (p<0.05); in terms of lower limbs muscle power, there was no significant difference in the height of vertical jump between AKO group and PL group (p>005); in terms of speed ability, there was no significant difference in 20-metre sprint time between AKO group and PL group (p>0.05). In conclusion, the short-term AKO supplementation can promote the recovery of muscle maximal strength in the lower limbs after high-intensity resistance exercise, and has no significant effects on the other muscle motor abilities. |
