The Intervention Composed of Aerobic Training and Non-Exercise Physical Activity (I-CAN)
This study will determine the health benefits of combining exercise training and increasing
the amount of physical activity in daily life on the fat around the abdomen, weight, fitness
and sensitivity to insulin. Volunteers will participate in one of three groups for 6 months:
1) a control group, 2) exercise training only, or 3) exercise training and increasing
physical activity outside of training. The exercise training will follow the public health
recommendations for exercise (150 minutes/week of moderate exercise). The group increasing
physical activity along with exercise training will be asked to increase physical activity
in their daily life (up to 3,000 step/day above their current levels through the use of step
counters), and meetings focused on behavior modification. The investigators hypothesize that
combining aerobic training and additional physical activity after training will have the
most profound reduction on waist circumference and body composition.

The Intervention Composed of Aerobic Training and Non-Exercise Physical Activity (I-CAN)
study will investigate the effects of aerobic exercise training and increasing the amount of
physical activity outside of training (Non-EX PA) on waist circumference, weight, and other
cardiovascular disease risk factors in a prospective pilot trial. The investigators will
randomize sedentary (<6,500 steps per day) obese adults with at least one additional
cardiovascular risk factor (N= 45) to a: (1) structured aerobic exercise program with no
intervention on Non-Ex PA (AERO group, N=15); (2) structured aerobic exercise program with
the additional goal of increasing Non-EX PA (AERO-PA group, N=15), or (3) a non-exercise
control group (CON, N=15) for 6 months. Exercise groups will participate in the same aerobic
training program (50 to 75% VO2 max), designed to be consistent with public health
recommendations of 150 minutes per week of moderate physical activity. Non-Ex PA in the AERO
group will be tracked throughout the entire 6 month intervention with pedometers capable of
counting steps, but not displaying them to the participant (blind mode capable). The AERO-PA
group will progressively increase Non-Ex PA throughout intervention using pedometers (a
progressive increase of 1,000 to 3,000 steps per day above baseline levels). The AERO-PA
group will also participate in lifestyle counseling grounded in the principles of the
behavioral change theories to determine/reinforce strategies to increase Non-Ex PA. The
primary outcome measure will be change in waist circumference following the intervention.
The results of this pilot study will be used to determine the efficacy/feasibility of the
intervention, and power a larger trial as an R01 application.
