what are some contributing factors to body weight maintenance?

genetics, epigenetics, social and physical environment, biological, and psychological variables

what is the minimal weight loss and maintenance that can reduce CVD risk factors?

2-3%

what is the potential weight loss associated with less than 150 min/week of aerobic exercise?

what are recommended exercise testing protocols for those who are overweight or obese?

modified balke, 6 minute walk test, modified Naughton, YMCA cycle ergometry

what are considerations for exercise testing?

musculoskeletal or orthopedic limitations may require alternate testing modes, medications that may alter HR or BP response at rest or during exercise, exercise equipment should be assessed for maximal weight and fit to ensure safety and comfort, assessment equipment should be appropriate to accurately determine weight, BP, HR, and BF percentage, environmental factors should be considered to ensure a temperature regulated climate
