【摘要】：目的观察平原及高原武警部队战士5000 m跑中某些生理生化指标变化。方法平原组和高原组战士各32名进行5 000 m跑,检测每圈(400 m)跑动过程中的心率及运动后血乳酸水平。结果随着跑动圈数的增加,两组运动中每圈的心率呈逐渐增加的趋势,平原组到第6圈和最后1圈心率〔(181±5)b.min-1、(187±4)b.min-1〕均明显高于高原组〔(176±6)和(180±5)b.min-1〕(P0.05,P0.01)。运动后即刻,平原组血乳酸水平〔(13.2±1.2)mmol.L-1〕明显高于高原组〔(11.4±1.2)mmol.L-1〕(P0.01)。恢复6~7 min后两组心率都降到120 b.min-1以下,但血乳酸水平依然较高。结论高原战士耐力跑中心率和血乳酸水平低于平原战士。因此,不同地区战士进行体能训练时,应根据该特点进行适宜负荷安排。
[Abstract]:Objective to observe the changes of some physiological and biochemical indexes in 5000 m running in plain and plateau armed police units.Methods A total of 32 soldiers in plain group and 32 soldiers in high altitude group were tested for heart rate and blood lactate level after exercise.Results with the increase of the number of running circles, the heart rate of each lap in the two groups increased gradually, and the heart rate of the plain group at the 6th and the last lap was significantly higher than that of the plateau group by 181 卤5nb 路min-1 + 187 卤4nb 路min-1) and 180 卤5b.min-1m-1 (P0.05P0.05P0.01).Immediately after exercise, the serum lactate level in the plain group (13.2 卤1.2 mmol.L-1) was significantly higher than that in the plateau group (11.4 卤1.2mmol.L-1).After 6 ~ 7 min, the heart rate of both groups decreased below 120 b.min-1, but the level of blood lactic acid was still high.Conclusion the rate of endurance running center and the level of blood lactic acid in plateau soldiers are lower than those in plain soldiers.Therefore, when the soldiers from different areas train their physical ability, they should arrange the appropriate load according to the characteristics.
