Field Methods to Estimate Fat-free Mass in International Soccer Players

Based on the high financial and logistical costs associated with the assessment of body composition with dual-energy X-ray absorptiometry (DXA), this study determined which field method has the best correlation with DXA data, and developed an equation to estimate fat-free mass (FFM) using the field anthropometric data in international soccer players. A total of 17 international soccer players participated in this study. DXA values provided a criterion measure of FFM. Correlation coefficients, bi...

Comparison of Oxygen Uptake Kinetics During Severe-intensity Laboratory and Field Cycling

The O₂-kinetic response to constant work rate exercise provides an insight into the adjustment of systemic oxygen transport and muscle metabolism. Whether O₂-kinetics measured in laboratory conditions reflect O₂-kinetics in field conditions has not yet been analysed. The aim of this study was to compare O₂-kinetics between field and laboratory conditions. Thirteen competitive male cyclists (mean±SD age 23.3±4.1 years; V̇O_2peak68.2±4.7 mL^.min^−1.kg⁻¹) completed two 6-min severe-intensity trials at...
