本研究旨在确定虾青素对骨骼肌损伤标志物的影响。20个受过抵抗训练的人（平均值+/-平均值的标准误：年龄，25.1 ± 1.6岁;身高，1.79 ± 0.02 m;体重，86.8 ± 4.4 kg）被分配至安慰剂组或安慰剂组（1732 mg红花油，n = 10）或虾青素（BioAstin; 1732 mg红花油;红球藻藻提取物[含有4 mg虾青素和480 mg叶黄素]，n = 10）。受试者在离心运动前3周（10组，每组10次重复，最大重复次数为85%）和运动后96小时内接受指定治疗。肌肉酸痛，肌酸激酶（CK）和肌肉性能进行了测量之前和96小时后的运动。对于所有因变量，两个治疗组观察到类似的反应，表明在阻力训练的男性中，虾青素补充剂不会有利地影响偏心负荷后骨骼肌损伤的间接标志物。
This investigation was designed to determine the effects of astaxanthin on markers of skeletal muscle injury. Twenty resistance trained men (mean +/- standard error of the mean: age, 25.1 +/- 1.6 y; height, 1.79 +/- 0.02 m; weight, 86.8 +/- 4.4 kg) were assigned to either a placebo (1732 mg safflower oil, n = 10) or astaxanthin (BioAstin; 1732 mg safflower oil; haematococcus algae extract [contains 4 mg astaxanthin and 480 mg lutein], n = 10). Subjects consumed their assigned treatment for 3 wk prior to eccentric exercise (10 sets of 10 repetitions at 85% of one repetition maximum) and through 96 h post-exercise. Muscle soreness, creatine kinase (CK), and muscle performance was measured before and through 96 h post-exercise. A similar response was observed for both treatment groups for all dependent variables, indicating that in resistance trained men, astaxanthin supplementation does not favorably affect indirect markers of skeletal muscle injury following eccentric loading.
