Sickle cell trait (SCT) is hereditary and generally considered a harmless condition. However, those with SCT might be at increased risk for exertion-related events that can be life-threatening. It’s important to be aware of risk factors that could trigger such events. These include being overweight and not physically fit, taking dietary supplements with stimulants and/or diuretics, being dehydrated, limiting recovery when engaged in repetitive, high-intensity exercise such as serial sprints, exercising at high altitude or in warm temperatures, or pressure from a peer or superior to finish a high-intensity workout or physical fitness test.
It’s crucial to maintain excellent conditioning and acclimation before attempting heavy exertion. Make sure to seek prompt medical attention if a Warfighter with SCT shows any signs of an impending medical emergency during exercise. Symptoms include unusual muscle pain or weakness with exercise, exercise-related collapse (many times consciously complaining of an inability to get up secondary to weakness), and struggling to keep up with others.
