Inclusion criteria
* Age \>18 years, as determined by birth date given on participation form. * Actively involved in competitive athletics * Able to give informed consent
Exclusion criteria
* Any known prior autonomic dysfunction * History of seizures or taking anti-seizure medication * Known learning disability or attention deficit disorder * Chronic heart conditions such as arrhythmias or valvular disease * History of diabetes mellitus * Taking any prescription stimulants such as Ritalin, Focalin, etc. * Use of any performance-enhancing drugs * Any deviation from normal found on the pre-participation physical exam such as the presence of a murmur or hypertension.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in PD2i following strenuous exercise bout of 45 minutes | Baseline at zero minutes and within 60 minutes of completion of strenuous exercise bout. | 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
| Measure | Time frame | Description |
|---|---|---|
| Change in PD2i following an injury during competitive sports. | Baseline PD2i at zero and within 60 minutes of cessation of exercise bout. | If an athlete participating in the research sustains an injury the PD2i analysis will be obtained and correlated to the baseline analysis. |
