Body Mass Index is associated with endurance performance in athletes. Reported and measured values of body mass and body height in 1,618 endurance athletes (1,358 men, 260 women) showed that men and women both underestimated their body mass and overestimated their body height, leading to an underestimation of Body Mass Index. There were age and sex differences in estimates of height and weight; for both women and men, underestimation of Body Mass Index amounted to 0.4 kg/m2. Master athletes tended to underestimate their body mass and overestimate their body height thus leading to significant differences between estimated and measured Body Mass Index. However, the magnitude of underestimation of BMI probably has a negligible influence on performance predictions. The differences between measured and estimated body mass, height, and BMI were within the range of normal daily variation, and for body height even within the precision of the measurement (0.5 cm).
体重指数与运动员的耐力表现有关。在 1618 名耐力运动员（1358 名男性，260 名女性）的身体质量和身高的报告和测量值中，男性和女性都低估了他们的体重，高估了他们的身高，导致体重指数被低估。身高和体重的估计存在年龄和性别差异；对于女性和男性来说，体重指数的低估量为 0.4kg/m2。大师运动员往往低估自己的体重，高估自己的身高，从而导致估计和测量的体重指数之间存在显著差异。然而，BMI 的低估幅度可能对性能预测的影响可以忽略不计。测量值和估计值之间的差异体重、身高和 BMI 都在正常日常变化范围内，而对于身高甚至在测量精度范围内（0.5 厘米）。
