Abstract |
|
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.
Keywords:
Obese, performance, supramaximal exercise, plasma
decreases, adolescents, boys.
