目的探讨β-胡萝卜素、大豆肽和蚕蛹蛋白对提升高海拔地区移居人群体力作业能力的影响。方法在海拔5100 m将40名青年随机分为4组,分别为β-胡萝卜素组、大豆肽组、蚕蛹蛋白组、对照组(口服安慰剂)。于服用前运动前、服用前运动后、服用后运动后分别检测血液生化指标。结果⑴服用后与服用前比较,β-胡萝卜素组VO2max、静息SaO2增高,蚕蛹蛋白组和大豆肽组VO2max、PWC170、台阶指数、静息和运动后SaO2均增高,有显著性差异(P<0.05或0.01)。与对照组比较,服用后运动后3组SaO2均增高,蚕蛹蛋白组和大豆肽组台阶指数增高,大豆肽组VO2max增高,有显著性差异(P<0.05,P<0.01)。⑵服用后运动后与服用前运动后比较、与对照组服用后运动后比较,ALT、AST、TB、DB均降低,有显著性差异(P<0.05,P<0.01);NOS、NO、SOD均增高,MDA降低,有显著性差异(P<0.05,P<0.01);Glu均增高,BUN、BLA降低,有显著性差异(P<0.05,P<0.01)。结论β-胡萝卜素、大豆肽和蚕蛹蛋白均可提高高原机体作业能力,增强机体抗氧化作用,延缓运动性疲劳发生。
Objective To investigate the effects of β-carotene, soybean peptide and pupa protein on improving the manual work ability of migrants in high altitude areas. Methods Forty young adults were randomly divided into 4 groups at 5,100 m altitude. They were β-carotene, soybean peptide, pupa protein and control group (oral placebo). Before taking exercise before taking exercise before taking exercise after taking blood biochemical indicators were detected. Results (1) The VO2max and resting SaO2 in β-carotene group were significantly higher than those before taking PO2max, PWC170, step index, resting and post-exercise SaO2 in pupa protein group and soybean peptide group (P <0.05 or 0.01). Compared with the control group, SaO2 in three groups increased after exercise, and the step index of pupa protein group and soybean peptide group increased, VO2max in soybean peptide group increased significantly (P <0.05, P <0.01). (2) Compared with the control group after exercise, the levels of ALT, AST, TB and DB in the control group were significantly decreased (P <0.05, P <0.01); NOS, NO, SOD (P <0.05, P <0.01); Glu increased, BUN, BLA decreased, there was a significant difference (P <0.05, P <0.01). Conclusion β-carotene, soybean peptide and pupa protein can improve the working ability of plateau, enhance the body’s anti-oxidation and delay the occurrence of exercise-induced fatigue.
