ABC-TV’s “Good Morning America” featured UCSF exercise physiologist Joseph Smith and the Human Performance Center in a February 28 story comparing calorie counters on gym equipment and sports watches to the actual number of calories that exercisers burn. To make this comparison, the correspondent visited the UCSF Human Performance Center to get a true measure of her actual metabolic rate, calorie expenditure and VO2 max, which represents aerobic capacity. She used these calculations as the scientific measure to rate the gym equipment and watches. Smith explained that watches and gym equipment estimate the number of calories burned whereas performance tests measure an exerciser’s actual metabolic expenditure.Patient Care News Center Topics: Orthopedics, Sports Medicine and Physical Therapy
