[Q]: Question: Does post-exercise heart-rate recovery correlate to resting heart-rate variability in healthy men?
Answer: HRR from the 1st to 5th min post-exercise negatively correlated with parasympathetic modulation in resting orthostatic, but showed no correlation in supine position. At the 3rd and 5th min, a positive correlation with combined sympathetic-parasympathetic modulation in both positions was observed.
[A]: yes


[Q]: Question: Does combined isometric and vibration training enhance strength beyond that of isometric training alone?
