简要总结
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.
详细描述
Obesity is one of the leading public health problems worldwide and is strongly associated with cardiovascular diseases, diabetes, musculoskeletal disorders, and psychological problems. In addition to medical complications, obesity also negatively affects quality of life, daily activities, and mental well-being. According to epidemiological studies, the prevalence of obesity is steadily increasing, particularly among women, and this situation creates a serious burden on health systems.
Regular physical activity is one of the most effective non-pharmacological methods for the management of obesity. Exercise improves cardiovascular health, increases muscle strength, supports balance, reduces depressive symptoms, and contributes to weight control. Despite these benefits, adherence to exercise programs in obese individuals is often low, and sustaining physical activity over the long term remains a challenge.
Previous studies have reported that supervised exercise programs are more effective in ensuring adherence and providing functional and psychological benefits compared to unsupervised programs. However, home-based exercise programs are easier to access, more cost-effective, and provide flexibility in daily life. Nevertheless, lack of professional supervision may reduce motivation and exercise quality, leading to lower adherence and limited health benefits.
Physiotherapy and rehabilitation interventions for obesity generally include aerobic training, muscular endurance and strengthening exercises, posture and balance training, and core stabilization. Multimodal exercise programs that combine these approaches can improve both physical and psychological outcomes. Still, the optimal supervision duration in such exercise programs has not been clearly defined in the literature. While some studies emphasize the advantages of fully supervised training, others suggest that partial supervision combined with home-based practice may also be effective.
In this context, it is important to investigate whether extended supervision provides superior outcomes compared to a shorter period of supervision followed by home-based training. This information may help clinicians to design exercise programs that are both effective and sustainable for obese patients.

研究组 & 干预措施
Group 1= 6-week supervised plus 6-week home-based program
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.
干预措施: Exercise program with supervised and home-based components (Other)
Group 2= Fully supervised 12-week program
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.
干预措施: Fully supervised exercise program (Other)
结局指标
主要结局
Exercise adherence
时间窗: 12 weeks
Exercise adherence was calculated as the percentage of prescribed multimodal exercise sessions completed. Adherence was evaluated separately during weeks 1-6, when both groups received supervised exercise, and during weeks 7-12, when Group 1 transitioned to home-based exercise while Group 2 continued supervised exercise. Supervised-session attendance was documented by the physiotherapist. During the home-based phase, Group 1 documented completed sessions in exercise diaries, which were reviewed during weekly telephone follow-ups.
