KUNMING (China) |
| الملخص (بالإنجليزية): |
Male Kunming mice were randomly divided into four groups of equivalent average body weight: a vehicle control group, a positive control group, and low and high dose whey peptide compound powder groups. After 30 days, each group was subjected to the forced swimming test [mice swim for 45 minute at(25±1) ℃]. After 35 days, prior to and after swim testing, lactate dehydrogenase(LDH), blood lactic acid(LAC), blood urea nitrogen(BUN)and hepatic glycogen content were determined. Swimming times of mice in the whey peptide compound powder groups were significantly prolonged compared with those in the control group (P<0.01). Mice in the whey peptide compound powder groups displayed obviously increased LDH activity and hepatic glycogen storage(P<0.01). Mice in the whey peptide compound powder groups displayed significantly blood lactic acid and BUN clearance after swimming(P<0.01). The above results indicated that whey peptide compound powder confered anti-fatigue effects. In addition, an anti-fatigue sports supplement composed of whey peptides, β-hydroxy-β-methylbutyrate(HMB), L-carnitine, and B vitamins etc., was developed, and systematic research has been carried out, and the quality of the products was evaluated.

| Abstract (Chinese): |
将雄性昆明小鼠随机分为 4 组：空白对照组、阳性对照组、低剂量和高剂量乳清多肽复合粉组。在给予受试物 30 d 后测定各组负重游泳的持续时间。实验前及实验第 35 天，小鼠在水温（25±1）℃的水中游泳 45 min，测定乳酸脱 氢酶（lactate dehydrogenase，LDH）、血乳酸（blood lactic acid，LAC）、血尿素氮（blood urea nitrogen，BUN）和肝糖原等生化 指标。乳清多肽复合粉组小鼠游泳时间明显大于对照组（P＜0.01）；服用乳清多肽复合粉的小鼠 LDH 活力、肝糖原水 平均比对照组显著增加（P＜0.01），运动后血乳酸及 BUN 水平明显降低（P＜0.01）。上述结果表明：乳清多肽复合粉具有 抗疲劳作用。同时对以乳清多肽、β-羟基-β-甲基丁酸盐（β-hydroxy-β-methylbutyrate，HMB）、L-肉碱、B 族维生素等 为主要组分的抗疲劳运动补剂进行质量评价。 [ABSTRACT FROM AUTHOR] |
