有氧能力是自行车运动员最重要的专项生理机能之一,而心脏功能是决定有氧能力的重 要环节。本文目的是探讨自行车训练引起运动员心脏结构变化的特点,及其与发展有氧代谢能力和专项耐力工作能力的关系。以便为全面评定运动员的心肺功能水平和选材提供科学依据。 24名1986年亚运会集训队的男女公路和场地自行车运动员,健将23名,平均年龄22.9-23.6(18-27)岁,专业训练平均6年(2-10年)以上。另10名为无等级的省级自行车运动员。自冬训至测试期(6—7个月)按各专项特点进行了系统大运动量训练。公路运动员骑行距离达17,000公里,最高时速50公里/小时。运动成绩相应提高。运动员体力适应良好。受试者经询问病史,测安静脉搏、血压、心电图、摄x光片及物理学检查,未见心血管系统异常。 Aerobic capacity is one of the most important specialized physiological functions of a cyclist, and heart function is an important part of determining the aerobic capacity. The purpose of this paper is to explore the characteristics of athletes’ cardiac structure caused by bicycle training and its relationship with the development of aerobic metabolism and special endurance work ability. In order to provide a scientific basis for the comprehensive assessment of cardiopulmonary function and selection of athletes. Twenty-four male and female road and field cyclists of the 1986 Asian Games training team were athletes of 23 athletes, with an average age of 22.9-23.6 (18-27) years and professional trainings of more than 6 years (2-10 years). The other 10 were non-grade provincial cyclists. From winter training to testing period (6-7 months) according to the special characteristics of the system a large amount of exercise training. Road athletes ride a distance of 17,000 km and a top speed of 50 km / h. Sports scores increased accordingly. Athletes fit well. Subjects were asked to ask a medical history, to measure the quiet pulse, blood pressure, electrocardiogram, X-ray film and physical examination, no cardiovascular system abnormalities.
