Outcomes
Primary outcome [1] 3698 0
Anaerobic threshold obtained for heart rate response during dynamic exercise carry out in cycle ergometer and carry out in treadmill
Timepoint [1] 3698 0
The anaerobic threshold was measured straight after the the subjects had already participated in program of cardiac rehabilitation (approximately 6 to 5 years on average)
Secondary outcome [1] 6243 0
To compare the anaerobic threshold and the heart rate variability in the dynamic exercise carry out in cycle ergometer and carry out in treadmill in a group of subjects with coronary heart disease
Timepoint [1] 6243 0
The protocol (cycle or treadmill) was applied so randomized with an interval of one week at least between them. The comparisons were made after the data's collection
