项目摘要

1) Ten healthy boys aged 12-13 years old were studied before and after ground running training for eight weeks which was prescribed for 12 min per day, three times per week. The stroke volume at rest showed significant 15.3% increase with a significant 4.3% enlarge of left ventricular end systolic diameter (Ds). VO_2max and AT-VO_2 after training showed significant increase by 15.2% and 19.4%, respectively. This study showed that 12 min running training in children of school age causes a development on the cardiac function and aerobic work capacity.2) Six long distance male runners aged 19-22 years old were studied before and after treadmill running training at 3,000m simulated altitude which was prescribed for 30 min per day, three timespan week at a submaximal load of 70-80% VO_2max for 8 weeks. Anaerobic threshold (OBLA-VO_2, OBLA-speed) at sea level after training increased by 13.7% and 13.3% in altitude training group, While there was no increase in control group. From these results, it might be suggested that this simulated high altitude training could improve aerobic work capacity and running performance.3) Six male rugby players aged 18-21 years old trained at 1,500m simulated altitude for 8 weeks, 3 sessions per week, each session consisting of continuous cycling for 30 min (75% VO_2max). OBLA-VO_2 at sea level after training showed significant 6.2% increase, while the value in control group almost the same. Altitude training group showed significant increase of 18.4% and 39.4% in total work after training, while control group showed increases of 14.6% and 24.4%, respectively.From these results, it may be concluded that training under hypobaric hypoxia contributed more to the improvement of work capacity at sea level, due to the accerelation of the TCA action mechanism in muscle cells and the inhibition of glycolytic metabolism.

1）在训练八周之前和之后，对十名12-13岁的健康男孩进行了研究，每天开处方12分钟，每周三次。休息时的中风体积显示出显着15.3％的增加，左心室收缩直径（DS）显着4.3％。训练后的VO_2MAX和AT-VO_2分别显示出显着增加15.2％和19.4％。这项研究表明，对学龄儿童进行12分钟的训练会导致心脏功能和有氧工作能力的发展。2）六名长距离男性跑步者在3,000m模拟的高度上进行了跑步机跑步之前和之后，研究了每天30分钟的跑步机跑步培训，每天30分钟，每周三次，三个时间板周，在70-80％vo_2max的70-80％vo_2max下进行了三个时间板的载荷。在训练后，海拔训练组增加了13.7％和13.3％，而对照组没有增加。从这些结果中可以提出，这种模拟的高空训练可以提高有氧工作能力和跑步性能。3）六名男子橄榄球运动员，年龄在18-21岁的男性橄榄球运动员，在1,500亿个模拟高度进行8周，每周3次训练，每周3个会议，每次训练，每次训练包括连续循环30分钟（75％VO_2max）。训练后的海平面上的Obla-vo_2显示出明显增加6.2％，而对照组的价值几乎相同。高空训练组的训练后总工作量显着增加了18.4％和39.4％，而对照组的增加分别增加了14.6％和24.4％。从这些结果来看，由于低氧缺氧下的训练在肌肉中的训练和GTCA的加速性glyctions insol gycrib ins ins ins ins ins ins ins ins ins ins ins ins ins ins ins ins ins ins gyc ins ins ins ins ins ins ins ins ins ins ins ins ins ins ins ins ins ins ins ins ins ins ins ins gly，因此可以得出结论。
