Brief Summary

Obesity is one of the most common health problems worldwide and is associated with many chronic diseases. Regular physical activity is known to play an important role in weight control, balance, quality of life, and mental health. However, obese individuals often have low adherence to exercise programs, and long-term maintenance of physical activity remains a major challenge. Previous studies have shown that supervised exercise programs are effective in improving functional capacity and psychological well-being. On the other hand, home-based programs are less costly and more accessible, but adherence and effectiveness may be limited without professional supervision. To date, there is limited evidence on the optimal supervision duration needed to achieve sustainable improvements in obese women. In the present study, it is aimed to investigate the effects of a 12-week individualized multimodal exercise program with different supervision durations (6 weeks supervised + 6 weeks home-based vs. 12 weeks fully supervised) on adherence and health outcomes in obese women. It is thought that prolonged supervision may increase exercise adherence, improve balance and functional performance, reduce depressive symptoms, and contribute positively to the quality of life. The results of this study may guide the design of future exercise programs for obesity management and provide evidence for more effective and sustainable rehabilitation approaches.

Outcome Measures

Primary Outcomes (1)

• Exercise adherence

  Adherence to the exercise program was assessed by the percentage of completed exercise sessions recorded in exercise diaries (participant-reported), attendance checklists maintained by the supervising physiotherapist during supervised sessions, and weekly telephone follow-up logs during the home-based phase (weeks 7-12 for Group 1).

  12 weeks

Secondary Outcomes (3)

• Functional lower extremity strength

  Baseline, 6 weeks, 12 weeks

• Balance

  Baseline, 6 weeks, 12 weeks

• Aerobic exercise capacity

  Baseline, 6 weeks, 12 weeks

Other Outcomes (3)

• Health-related quality of life

  Baseline, 6 weeks, 12 weeks

• Depressive symptoms

  Baseline, 6 weeks, 12 weeks

• Physical activity level

  Baseline, 6 weeks, 12 weeks

Study Arms (2)

Group 1= 6-week supervised plus 6-week home-based program

OTHER

Participants perform a 12-week multimodal exercise program targeting balance, muscular strength, core endurance, and cardiovascular fitness. Weeks 1-6 are supervised; weeks 7-12 are home-based via a video catalogue. Walking ≥30 min on ≥2 non-training days is encouraged.

Other: Exercise program with supervised and home-based components

Group 2= Fully supervised 12-week program

OTHER

Participants perform a fully supervised 12-week multimodal exercise program including warm-up, balance, aerobic, strength, and core exercises. Walking ≥30 min on ≥2 non-training days is included.

Other: Fully supervised exercise program

Interventions

Exercise program with supervised and home-based components OTHER

The 12-week program targets balance, muscular strength, core endurance, and cardiovascular fitness. Weeks 1-6 are supervised; weeks 7-12 are home-based via a video catalogue. Walking ≥30 min on ≥2 non-training days is advised. Intensity, repetitions, and sets are individualized using Borg CR-6-20. Adherence is monitored via exercise diaries and weekly phone calls with adjustments as needed.

Group 1= 6-week supervised plus 6-week home-based program

Fully supervised exercise program OTHER

The 12-week program is fully supervised and includes warm-up, balance, aerobic, strength, and core exercises. Walking ≥30 min on ≥2 non-training days is included. Intensity, repetitions, and sets are individualized using Borg CR-6-20. Adherence is monitored by a physiotherapist using exercise diaries.

Group 2= Fully supervised 12-week program
