耐久跑是人体在氧气供应充足的情况下长时间运动的能力,其最大特点是持续时间长,运动强度较小,能量消耗量大,运动中能源来源大部分是有氧代谢,所以有氧代谢的顺利进行,是耐力素质的基础。经常锻炼可使呼吸系统的功能得到改善和提高,表现为呼吸肌强壮有力,胸廓活动幅度增大,同时心脏收缩力加强,心脏供血能力提高,促进有氧代谢能力的发展。这种有氧代谢的运动对于提高学生们的心血管系统的功能和肺呼吸系统的功能都
Durable running is the ability of the human body to exercise for a long time under the condition of sufficient oxygen supply. Its most prominent feature is its long duration, less exercise intensity, large energy consumption and most energy sources during exercise are aerobic metabolism. Therefore, aerobic metabolism The smooth progress is the basis of endurance quality. Regular exercise can improve and enhance the function of the respiratory system, manifested as strong and powerful respiratory muscles, increased amplitude of the thorax activity, while strengthening cardiac contractility, increased cardiac blood supply, and promote the development of aerobic metabolism. This aerobic metabolism of the exercise to improve the students’ cardiovascular system function and lung respiratory system function
