A cool-down is the portion immediately following an exercise session that allows the body to gradually transition from an exertional state to a resting or near resting state. Cool-downs should involve a gradual yet continuous decrease in exercise intensity (i.e. from a hard run to an easy jog to a brisk walk), a period of stretching, and rehydration. Durations can vary for different people, but 5-10 minutes is considered adequate. A typical cool-down my consist of a slow jog or walk. Ingestion of a sports drink or some form of carbohydrate is recommended following exercise sessions that last longer than one hour.
