Useful Variables to Record for Determinung the Association Between Meteorologic Conditions and Exertional Heat Illness (EHI) Incidence in Athleticsa
| Variables recorded daily |
| Sport type (continuous or noncontinuous) |
| Date and start time of exercise session |
| Weather conditions (eg, wet bulb globe temperature) |
| Number of participants per session |
| Exercise duration |
| Relative exercise intensity (low, moderate, high) |
| Clothing or equipment configuration |
| Variables recorded per EHI incident |
| EHI typeb (eg, exercise-associated muscle cramps, heat syncope, heat exhaustion, heat injury, exertional heat stroke) |
| Age, sex |
| Field position (eg, offense, defense, goalkeeper) |
| History of recent illness and EHI |
| Use of medications or supplements |
| Patient body mass and body composition |
| Heat-acclimatization status (ie, completed >10 d of organized practice in heat within last 3 mo) |
a
EHI incidence rate can be computed as the number of EHI incidents or total athlete-exposures. Incidence rates may be computed for each EHI type.
