Measure
Aerobic First, Resistance Second
Subjects will complete three 15 minute periods of aerobic exercise, with 10 minute recovery between each period. This will be followed by 5-15 minute periods of up to 7 activities of daily living with an additional 20 minute period of resistance exercise, such as straight leg raises. Aerobic Exercise: Exercise for three 15 minute periods, with 10 minute rests between each period, and exercise intensity will vary between periods to achieve different energy expenditures, which may be determined based on VO2 measurements. Resistance Exercise: Subjects will perform 5-15 minutes of up to 7 different activities of daily living, followed by 20 minutes of resistance exercise, such as straight leg raises.
