Summary

Check the acute influence of caffeine on the autonomic modulation and cardiorespiratory parameters after aerobic exercise. Hypothesized that caffeine can promote a slower recovery of the cardiorespiratory parameters and the SNA recovery after aerobic exercise.

Conditions

  • Autonomic Nervous System
  • Cardiorespiratory Parameters

Interventions

DRUG

Caffeine

Volunteers will consume 300 mg of caffeine in pills fifteen minutes before treadmill aerobic exercise.

DRUG

Placebo

Volunteers will consume 300 mg of placebo in pills fifteen minutes before treadmill aerobic exercise.

OTHER

Cardiopulmonary test

assessment of the maximum oxygen consumption (VO2max) on a treadmill (Inbrasport / Millennium), using Buce protocol. .

OTHER

Treadmill aerobic exercise

30 mim of aerobic exercise (5 minutes at speed of 5.0 km/h for warming-up followed by 25 minutes at 60% of VO2max ).
