What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in PD2i following strenuous exercise bout of 45 minutes | 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. | Baseline at zero minutes and within 60 minutes of completion of strenuous exercise bout. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in PD2i following an injury during competitive sports. | If an athlete participating in the research sustains an injury the PD2i analysis will be obtained and correlated to the baseline analysis. | Baseline PD2i at zero and within 60 minutes of cessation of exercise bout. |
