Further study details as provided by University of Mississippi Medical Center:

Primary Outcome Measures:
  • Change in PD2i following strenuous exercise bout of 45 minutes [ Time Frame: Baseline at zero minutes and within 60 minutes of completion of strenuous exercise bout. ] [ Designated as safety issue: Yes ]
    PD2i analysis of HRV measured before and after strenuous exercise in each sport. The change from baseline will be correlated to return to resting heart rate.


Secondary Outcome Measures:
  • Change in PD2i following an injury during competitive sports. [ Time Frame: Baseline PD2i at zero and within 60 minutes of cessation of exercise bout. ] [ Designated as safety issue: Yes ]
    If an athlete participating in the research sustains an injury the PD2i analysis will be obtained and correlated to the baseline analysis.
