-
Change of heart rate after submax exercise
Time frame: Baseline and every minute post exercise for a maximum 20 minutes post exercise.
The participants then were fitted to cycling shoes and familiarized with the Lode cycle ergometer (Lode Excalibur Sport, Groningen, Netherlands), completed a warm-up and were asked to perform a criterion work rate trial ending at 80% predicted HRmax. Heart rate was recorded every minute post exercise for a maximum of 20 minutes post exercise.
Sponsor's own description
The purpose of this study was to determine the effects of a pre-exercise, single practical dose of watermelon juice, Gatorade, sugar water or water on heart rate recovery, blood lactate levels, and 24-hour post exercise muscle soreness.
