The effect of aerobic and anaerobic physical conditioning on insulin and glucose during exercise

Abstract

Objective: Describe glucose and insulin behavior at the different phases of exercise in aerobic and anaerobic athletes. Materials and methods: Glucose and insulin from 6 anaerobic and 10 aerobic athletes were compared during rest, moderate-high intensity exercise, and recovery. Statistical analysis was performed to evaluate insulin and glucose behavior, and differences between aerobic aerobic and anaeribic-trained individuals. A p value of <0.05 was set. A non-normal distribution was found, non-parametric tests and multivariate analysis were performed. Results: Moderate exercise led to hypoinsulinemia, whereas intense exercise caused hyperinsulinemia and hyperglycemia. No differences were found between the 2 groups. Conclusions: Autonomic nervous system behavior may play a role in the glucoenergetic balance that could overcome insulin effect, and it could vary depeding on the type of exercise régimen but further evaluation is necessary to confirm these findings.
