Skinfold prediction equation for athletes developed using a four-component model.

Introduction: Skinfold (SKF) equations exist to predict percent body fat (%BF) in athletes; however, none have been derived from multicomponent model reference measures.

Purpose: To develop and cross-validate a %BF prediction equation based on SKF in athletes using a four-component model as the reference measure.

Methods: Subjects were 132 collegiate athletes (20.

Practice effect of the Wingate anaerobic test.

The purpose of this study was to investigate the presence of a practice effect on the Wingate anaerobic test (WAnT). Twenty-five young adult men (mean age = 20 years) performed 2 trials of the WAnT, which were separated by 7 days. Mean peak power (PP) and mean power (MP) for trials I and II were compared using a 1-way repeated measures analysis of variance to determine if a practice effect existed.
