Body Composition Characteristics of Elite Senior and Under 23 Australian Sprint Kayakers
2025
Overview
The aim of this study was to compare body composition characteristics of elite senior and U23 sprint kayak athletes and report body composition changes during the COVID-19-interrupted preparation for the Tokyo 2020 Summer Olympics. A total of 32 Australian kayakers (Men: 20 (Senior = 13, U23 = 7); Women: 12, (Senior = 5, U23 = 7)) undertook body composition assessment using dual-energy X-ray absorptiometry (DXA) from 2017 to 2021. The first DXA assessment for each athlete was used for a cross-sectional analysis to compare senior and U23 sprint kayak athletes. Of the thirty-two kayakers, five senior men kayakers had repeat DXA scans over the data collection period which were used to monitor longitudinal changes in body composition. Senior men kayak athletes were heavier than U23 athletes (p = 0.017; 10.4 ± 1.9 kg; d = 1.23) but had similar body composition. In contrast, body mass was not different between senior and U23 women kayak athletes (p = 0.187), however senior women athletes had a significantly higher lean body mass (LBM; p = 0.048; 5.1 ± 1.3 kg, d = 1.32) and lower body fat percentage (p = 0.011; −4.3 ± 0.8%, d = 1.82). The five senior men kayakers exhibited a non-significant decrease in fat mass (p = 0.774; 2.9 ± 3.0 kg, d = 0.97) and increase in LBM (p = 0.234; 2.2 ± 5.9 kg, d = 0.38) across the Olympic quadrennial with little change in body mass. Senior men kayak athletes while heavier, have similar body composition compared to their U23 counterparts, whereas senior women kayakers are similar in body mass but differ in body composition compared to their younger counterparts. The relative influence of maturation, specificity of training, or dietary strategies on the observed differences in body composition between senior and U23 men and women kayak athletes are currently unknown and warrant further investigation.
