EKBLOM，BJ~ RN.体育训练对美国裔男孩的影响。应用生理学杂志27（S）：S51）-355。1 WL-六个男孩，在实验开始时都是11岁，在6个月的体育训练之前和之后进行了研究。一个由7名同龄男孩组成的非训练组同时进行了研究。训练组的最大摄氧量从2.15升/分钟提高到2.48升/分钟（15%），但参考组没有变化。来自训练组的五名男孩继续训练了26个月，然后发现最大摄氧量总共增加了55“;（;），肺活量增加了547”，心脏容积增加了437“，这比从身高方面的身体尺寸的年龄依赖性增加所预期的要多。与图表中的生长估计值相比，训练组的身高随年龄增长的速度加快，但参考组的情况并非如此。次最大功和最大功;氧摄取;肺通气;心率;血乳酸;心脏容积;肺活量几项研究（3，7，11）表明，在耐力项目中成功的运动员的特点是非常高的有氧能力（最大摄氧量）和大尺寸（心脏体积，血液体积，肺体积）。然而，像这样的横断面研究并没有回答这些大的功能和静态维度是否取决于运动员的遗传或训练背景的问题，也没有阐明这两个因素的综合作用。
EKBLOM, BJ~ RN. Effect of physical trainirg in u&descent boys. J. Appl. Physiol. 27 (S): S51)--355. 1 WL---Six boys, all 11 years of age at the start of the experiment, were studied before and after 6 months of physical training. A nontraining group of seven boys of the same age was studied at the same time. The maximal oxygen uptake of the training group improved from 2.15 to 2.48 liters/min (15%), but was unchanged in the reference group. Five boys from the training group continued training for a further 26 months, and it was then found that maximal oxygen uptake had increased in total by 55’;(;, vital capacity by 547&, and heart volume by 437&, which was more than expected from the agedependent increase in body size in terms of body height. The training group had an accelerated rate of increase in body height with age, when compared with growth estimates contained in charts, but this was not the case in the reference group. submaximal and maximal work; oxygen uptake; pulmonary ventilation; heart rate; blood lactate; heart volume; vital capacity; growthSEVERAL STUDIES (3, 7, 11) have shown that successful athletes in endurance events are characterized by very high aerobic power (maximal oxygen uptake) and large dimensions (heart volume, blood volume, lung volume). Crosssectional studies like these do not, however, answer the question of whether or not these large functional and static dimensions depend on the athletes’ genetic or training background or elucidate the combined effect of these two factors.
