Aerobic Training and Non-Exercise Physical Activity

Summary

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.

Interventions

BEHAVIORAL

Aerobic Exercise Training

Individuals randomized to the aerobic exercise training group will participate in 6 months of supervised exercise training. Exercise dose (expressed in kilocalories per kg per week \[KKW\]) during aerobic training will be 8KKW in week 1, 10KKW in week 2 and 12 KKW in week 3. the exercise dose of 12KKW will be maintained throughout the intervention. Pedometers will be worn by participant in blind-mode throughout the intervention, and removed during exercise training sessions. Participants will enter information about whether they wore their pedometer on the study website. Aerobic exercise group participants will be told to make no conscious alterations to their physical activity or dietary habits

BEHAVIORAL

Aerobic Exercise+ Physical Activity

The Aerobic Exercise+ Physical Activity Group will participate in the same supervised exercise training intervention as the Aerobic Exercise Group, but will also increase the amount of non-exercise physical activity in their daily lives. After week 6 of intervention, participants will incrementally increase Non-Ex PA until they reach an average of 3,000 steps/day above baseline. Non-Ex PA will be increased with moderate physical activity consistent with daily living (i.e. leisurely walking in the evening, walking the dog etc.). Participants will also periodically have life-style counseling sessions with instructors with expertise in behavioral change support to their dietary habits
