The comparison of glucose and insulin concentration in elite sprint and endurance runners after an exhaustive aerobic exercise

The aim of present study was to comparison of glucose and insulin concentration in elite sprint and endurance runners after an exhaustive aerobic exercise.

Sixteen elite sprint (n=8; 3.8 ± 1.8 years experience of tournament playing, mean ± SD) and endurance (n-8; 6.2 ± 2.3 years experience of tournament playing, mean ± SD) runners volunteered to participate in this study. Blood samples were taken before, immediately, 30 and 120 min after the Bruce test. Glucose solution containing 75 g oral glucose dissolved in 250 ml of water to drink was consumed by subjects after the exercise.

The results showed that glucose and insulin level increased 30 and 120 min after the exercise in compare to basal level in both groups (P<0.05), while no significant difference was observed between the groups.

In conclusion, sprint and endurance running have similar effects on glucose and insulin concentration after an exhaustive exercise.
