The maximum amount of work a person can perform. Physical work capacity is usually related to a specific heart rate and is used as a measure of aerobic fitness. The most common test of physical work capacity is called the PWC170, which relates to the maximum amount of work that can be done at a heart rate of 170 beats min−1. This value is chosen because, for most people, it is a high, but well-tolerated work level. However, an extrapolation taken at maximum heart rate (assuming HR = 220—age) is sometimes used for athletes.
