This work examines the relationship between plasma volume variation and performance measured during supramaximal exercise among adolescents with different body weight statuses. Sixteen adolescents (normal-weight, over weight and obese) performed an exercise sprint on an ergometer cycle. Following exercise, plasma volume decreased significantly in the obese group and was associated with decreases in performance (r =-0.85, p<0.05) compared to the overweight and normal-weight groups (p<0.01). Our results suggest that the decrease in plasma volume that occurs after an exercise sprint test may limit performance during repeated sprint exercise in obese and overweight adolescent boys.
