Recovery of Heart Rate Variability Following Low- and High-Intensity Exercise

Understanding the effects of acute exercise on HRV will aid the standardisation of HRV measurement. Previous studies have examined the effects of exercise intensity on HRV at short (60min) or long (24hr) recovery intervals, often without a control group or condition. The present study aimed to assess the effects of high and low intensity cycling over a 6hr period relative to a non-exercise control condition.
