One hundred and twelve finalists in the State Swimming Championships aged between seven and twelve years and 65 ranked tennis players of similar age were selected on the basis of their sporting performances. A third group comprised children of similar socio-economic status who only took part in casual sport. The tests which were used in the study were those considered to be important for successful athletic performance. A multifactorial analysis of variance and post-hoc t-tests were applied to the data to determine if any statistical differences were apparent between the three groups. The results demonstrated that no size, body shape, flexibility, strength or lung function differences were evident between the competitors and non-competitors, but that the swimmers and tennis players were superior to the non-competitors in cardiovascular endurance.
在州游泳锦标赛中，根据体育成绩选出了112名年龄在7至12岁之间的决赛选手，以及65名年龄相仿、排名靠前的网球选手。第三组由社会经济地位相似、只参加休闲运动的儿童组成。该研究中使用的测试是那些被认为对成功的运动表现很重要的测试。对数据进行了多因素方差分析和事后t检验，以确定三组之间是否存在明显的统计差异。结果表明，参赛者和非参赛者在体型、身体形状、柔韧性、力量或肺功能方面没有明显差异，但游泳运动员和网球运动员在心血管耐力方面优于非参赛者。
