The need for a sports drink is only necessary during prolonged and intense activity or exercise lasting more than 60 minutes, particularly in hot weather or when exercise is at high intensity (e.g., intense sports practices, long runs, or triathlons). For typical short-to-moderate activity, water remains the best choice.
If an athlete is playing football for a couple of hours in hot weather or running a long race, a sports drink may be appropriate to replenish electrolytes and provide energy. Otherwise, water will suffice.
