游泳比赛也象径赛项目一样,有着从短距离速度性直到耐力性的各种不同项目。然而,由于游泳运动员的训练量很大,所以人们往往并不考虑运动员所从事的项目有所不同,而把游泳运动员都划归为耐力性训练的范畴。游泳运动员与其它耐力性运动员一样,其代谢能力和心输出量都很高,从而证实上述分类是有一定道理的。尽管游泳运动员是属于耐力性训练的运动员,但实际上游泳比赛的大多数项目却主要是速度性的,其持续时间不到两分钟。耐力性训练的运动员的无氧阈要比非运动员或速度性训练的运动员更高。这些结果主要来自对耐力跑和越野滑雪运动员的研究,而对短距离速度性项目则很少注意。既然游泳运动员也是耐力性训练的运 Swimming competitions, like the track events, have a variety of different projects ranging from short speed to endurance. However, due to the large amount of training of swimmers, people often do not consider the items that athletes engage in differently, and classify swimmers into endurance training. Swimming athletes, like other endurance athletes, have high metabolic capacity and cardiac output, confirming the above rationale. Although swimmers are endurance training athletes, in fact most of the swimming competitions are mostly speedy and last less than two minutes in duration. Endurance training athletes anaerobic threshold than non-athletes or speed training athletes higher. These results mainly come from the study of endurance runners and cross-country skiers, while the short-distance speed projects pay little attention. Since the swimmer is also endurance training
