Relationship between volition, physical activity and weight loss maintenance: Study rationale, design, methods and...

Area of Science:

• Behavioral science
• Exercise physiology
• Obesity research

Background:

• Weight loss maintenance remains a significant challenge for many individuals.
• Understanding the psychological and behavioral factors influencing long-term success is crucial.

Purpose of the Study:

• To investigate the relationship between volitional skills, physical activity levels, and weight loss maintenance.
• To identify predictors of successful weight loss maintenance following an intensive lifestyle intervention.

Main Methods:

• Prospective study involving 84 overweight/obese adults (55 women, 29 men).
• A 3-month intensive lifestyle intervention including supervised training, a hypocaloric diet, and lifestyle education.
• Monitoring of body weight, composition, volitional skills, physical activity, and maximal oxygen uptake before, during, and up to 12 months post-intervention.

Main Results:

• Participants will be categorized into clinical weight loss maintenance (>10%), moderate weight loss maintenance (1-10%), and no weight loss groups at 12 months.
• Statistical analyses (linear mixed models, correlational analyses) will compare volitional skills, physical activity, and maximal oxygen uptake across groups.
• Associations between volition, physical activity, and weight loss outcomes will be examined.

Conclusions:

• Specific volitional skills may predict adherence to physical activity and successful weight loss maintenance.
• Training identified volitional skills in future interventions could optimize weight management success.
• This research aims to refine lifestyle interventions for more effective and sustainable weight loss.
