A comparison of methods for the estimation of body composition in highly trained wheelchair games players by Vicky Goosey-Tolfrey, Mhairi Keil, Katherine Brooke-Wavell, Sonja de Groot

“…New prediction models found the Σ7 skinfolds and calf circumference as the best model to predict út (R2=0.84). In conclusion, BIA, ADP and existing skinfolds equations should be used with caution when estimating út of wheelchair athletes with substantial body asymmetry, lower body muscular atrophy and upper body muscular development.…”
