【摘要】：目的探討力竭運動后即刻給予葡萄糖和(或)富氫水對大鼠丙二醛、肌糖原、運動耐力隨時間的變化趨勢。方法通過對力竭運動后SD大鼠即刻灌胃給予生理鹽水(生理鹽水組)、富氫水(富氫水組)、葡萄糖(葡萄糖組)、葡萄糖和富氫水聯(lián)合(聯(lián)合組)等處理,檢測各恢復(fù)時間點(力竭運動后1、3、6、8 h)血清丙二醛、腓腸肌肌糖原濃度及運動耐力。結(jié)果 (1)組內(nèi)比較,各組內(nèi)各時間點丙二醛、運動耐力隨時間的變化趨勢差異無統(tǒng)計學(xué)意義,肌糖原含量有上升趨勢。(2)組間比較,富氫水組、聯(lián)合組丙二醛低于生理鹽水組(P0.05,P0.01);葡萄糖組、聯(lián)合組肌糖原顯著高于生理鹽水組(P0.01),聯(lián)合組運動耐力均顯著高于生理鹽水組(P0.01)。結(jié)論力竭運動后葡萄糖聯(lián)合富氫水能有效降低血清丙二醛,增加腓腸肌肌糖原,增加運動耐力;單獨給予葡萄糖僅能增加肌糖原;單獨給予富氫水僅能降低血清丙二醛;但在各實驗處理下,除肌糖原有隨時間上升趨勢外,血清丙二醛、運動耐力均無明顯變化趨勢。
[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.
