Estimation bias: body mass and body height in endurance athletes


Knechtle, B; Rüst, C A; Rosemann, T; Knechtle, P; Bescos, R (2012). Estimation bias: body mass and body height in endurance athletes. Perceptual and Motor Skills, 115:833-844.

Abstract

Body Mass Index is associated with endurance performance in athletes. Reported and measured values of body mass and body height in 1,607 endurance athletes (1,352 men, 255 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).
