Summary
The purpose of this study was to verify physiological responses to constant-load (continuous) vs. variable-intensity (interval) during 14 weeks of aerobic exercise on active men. The hypothesis was that would be differences in physiological variables on distinct modes of execution performed on the treadmill over a period of 14 weeks of training.
Eligibility Criteria
Inclusion Criteria
- self reporting no contraindication to high-intensity exercise.
- physically active on cardiorespiratory activities in a regular basis for at least six months.
