【摘要】：目的探讨力竭运动后即刻给予葡萄糖和(或)富氢水对大鼠丙二醛、肌糖原、运动耐力随时间的变化趋势。方法通过对力竭运动后SD大鼠即刻灌胃给予生理盐水(生理盐水组)、富氢水(富氢水组)、葡萄糖(葡萄糖组)、葡萄糖和富氢水联合(联合组)等处理,检测各恢复时间点(力竭运动后1、3、6、8 h)血清丙二醛、腓肠肌肌糖原浓度及运动耐力。结果 (1)组内比较,各组内各时间点丙二醛、运动耐力随时间的变化趋势差异无统计学意义,肌糖原含量有上升趋势。(2)组间比较,富氢水组、联合组丙二醛低于生理盐水组(P0.05,P0.01);葡萄糖组、联合组肌糖原显著高于生理盐水组(P0.01),联合组运动耐力均显著高于生理盐水组(P0.01)。结论力竭运动后葡萄糖联合富氢水能有效降低血清丙二醛,增加腓肠肌肌糖原,增加运动耐力;单独给予葡萄糖仅能增加肌糖原;单独给予富氢水仅能降低血清丙二醛;但在各实验处理下,除肌糖原有随时间上升趋势外,血清丙二醛、运动耐力均无明显变化趋势。
[Abstract]:Objective to investigate the effect of glucose and / or hydrogen rich water on malondialdehyde, muscle glycogen and exercise endurance in rats after exhaustive exercise. Methods SD rats were treated with saline (saline group), hydrogen rich water (hydrogen rich water group), glucose (glucose group), and combination of glucose and hydrogen rich water (combined group) immediately after exhaustive exercise. Serum malondialdehyde (MDA), glycogen concentration in gastrocnemius muscle and exercise endurance were measured at different recovery time points (1: 3 and 6 h after exhaustive exercise). Results (1) there was no significant difference in malondialdehyde (MDA) and exercise endurance with time, but the content of muscle glycogen increased in each group. (2) compared with the control group, the content of muscle glycogen in hydrogen rich water group was higher than that in hydrogen rich water group. Malondialdehyde in the combined group was lower than that in the saline group (P0.05, P0.01), the muscle glycogen in the glucose group was significantly higher than that in the saline group (P0.01), and the exercise endurance in the combined group was significantly higher than that in the saline group (P0.01). Conclusion after exhaustive exercise, glucose combined with hydrogen rich water can effectively reduce serum malondialdehyde, increase gastrocnemius muscle glycogen, increase exercise endurance, increase muscle glycogen only by glucose alone, decrease serum malondialdehyde by hydrogen rich water alone. However, there was no significant change in serum malondialdehyde and exercise endurance except for the increase of muscle glycogen over time.
