Gruppo di partecipanti / ArmGruppo di partecipanti / Arm |
Intervento / TrattamentoIntervento / Trattamento |
|---|---|
|
Comparatore attivo: Standard payment, phase 1
All participants will perform exercise training.
Participants in this arm will receive a fixed amount of money for exercise session lasting at least 20 minutes during weeks 1-16 (phase 1).
All exercise recommendations and outcome tests will be same for this group as the experimental group so that the two groups differ only in the financial incentives they receive for exercise behavior.
|
All participants will perform exercise training at the wellness center.
Exercise duration and intensity will be recorded with heart rate monitors.
|
|
Comparatore attivo: Standard payment, phase 2
All participants will perform exercise training.
Participants in this arm will receive a fixed amount of money for exercise session lasting at least 20 minutes during weeks 17-32 (phase 2).
All exercise recommendations and outcome tests will be same for this group as the experimental group so that the two groups differ only in the financial incentives they receive for exercise behavior.
|
All participants will perform exercise training at the wellness center.
Exercise duration and intensity will be recorded with heart rate monitors.
|
|
Comparatore attivo: Ramp-down payment, phase 3
All participants will perform exercise training.
This phase will last from weeks 33-48 (phase 3).
Participants in this arm will receive a fixed amount of money for exercise session lasting at least 20 minutes, but the value of the payments will decrease weekly (ramp-down) until reaching zero in week 41.
All exercise recommendations and outcome tests will be same for this group as the experimental group so that the two groups differ only in the financial incentives they receive for exercise behavior.
|
All participants will perform exercise training at the wellness center.
Exercise duration and intensity will be recorded with heart rate monitors.
|
|
Sperimentale: Incentivized payment, phase 1
All participants will perform exercise training.
Participants in this arm will receive an increasing amount of money when they increase exercise frequency (number of days) during weeks 1-16 (phase 1).
All exercise recommendations and outcome tests will be same for this group as the active comparator group so that the two groups differ only in the financial incentives they receive for exercise behavior
|
All participants will perform exercise training at the wellness center.
Exercise duration and intensity will be recorded with heart rate monitors.
|
|
Sperimentale: Incentivized payment, phase 2
All participants will perform exercise training.
Participants in this arm will receive an increasing amount of money when they exercise for longer than 20 minutes per session during weeks 17-32 (phase 2).
All exercise recommendations and outcome tests will be same for this group as the active comparator group so that the two groups differ only in the financial incentives they receive for exercise behavior
|
All participants will perform exercise training at the wellness center.
Exercise duration and intensity will be recorded with heart rate monitors.
|
|
Sperimentale: Raffle payment, phase 3
All participants will perform exercise training.
In weeks 33-48 (phase 3)participants in this arm will receive fewer financial incentives than in the prior 32 weeks but they will be delivered through a raffle system to utilize a variable reinforcement approach.
All exercise recommendations and outcome tests will be same for this group as the active comparator group so that the two groups differ only in the financial incentives they receive for exercise behavior.
|
All participants will perform exercise training at the wellness center.
Exercise duration and intensity will be recorded with heart rate monitors.
|
|
Nessun intervento: Normal weight, low activity group
This group of participants will complete only the baseline tests and assessments and will serve as a reference group.
They will be selected to have low physical activity and fitness like the intervention group.
Therefore differences in their results with the intervention group will reflect the effects of overweight/obesity on the variables of interest.
|
|
|
Nessun intervento: Normal weight, high activity group
This group of participants will complete only the baseline tests and assessments and will serve as a reference group.
They will be selected to have higher physical activity and fitness than the intervention group.
They will therefore serve as a healthy reference group and differences in their results with the intervention group will reflect the effects of both overweight/obesity and physical activity on the variables of interest.

Change From Baseline in Volume of Exercise (Total Time)
Lasso di tempo: at baseline (week 0) and weeks 16, 32, and 48.
|
Frequency and duration of moderate-to-vigorous physical activity will be measured using heart rate monitors.
The monitors will be worn each exercise session.
Participants are asked to complete 3 exercise sessions per week throughout the 48-week period of enrollment.
The primary comparison between the experimental and active comparator groups will be the volume of exercise (total time) accumulated.
Comparisons will be made for accumulated exercise volume at 16, 32, and 48 weeks and the change from baseline (week 0).

Insulin Resistance
Lasso di tempo: at baseline (week 0) and weeks 16, 32, and 48.
|
Fasting blood glucose and insulin concentration will be measured and used to calculate the homeostatic model of assessment for insulin resistance (iHOMA2, %S).
Testing will be performed at baseline (week 0) and weeks 16, 32, and 48.
Data analysis will focus on the change from baseline and whether that change differs between groups.

Lasso di tempo: at baseline (week 0) and weeks 16, 32, and 48.
|
Peak oxygen uptake (VO2max) during a progressive intensity bicycle test to fatigue.
Testing will be performed at baseline (week 0) and weeks 16, 32, and 48.
Data analysis will focus on the change from baseline and whether that change differs between groups.

|
Body fat content.
Testing will be performed at baseline (week 0) and weeks 16, 32, and 48.
Data analysis will focus on the change from baseline and whether that change differs between groups.
