Impact of Supervised Exercised Training Before Bariatric Surgery on Body Composition.

Area of Science:

• Bariatric Surgery and Metabolic Rehabilitation
• Exercise Physiology and Muscle Mass Maintenance
• Obesity and Post-Surgical Outcomes

Background:

• Maintaining muscle mass after bariatric surgery is crucial for long-term patient health and recovery.
• Pre-operative exercise interventions are explored as a strategy to mitigate muscle loss.
• Obesity presents unique challenges in implementing pre-surgical rehabilitation programs.

Purpose of the Study:

• To evaluate the effectiveness of a pre-bariatric surgery exercise program on muscle mass maintenance.
• To assess the impact of a metabolic rehabilitation protocol on physical activity habits post-surgery.

Main Methods:

• Nonrandomized, retrospective, single-center study including 178 patients undergoing bariatric surgery.
• Comparison between an exercise group (metabolic rehabilitation protocol) and a control group.
• Data collected on demographics, body mass index (BMI), lipid profiles, and C-reactive protein (CRP).

Main Results:

• The exercise group showed a trend towards a higher increase in muscle mass (6.3% ± 5.2%) compared to the control group (5.2% ± 4.4%), though not statistically significant (p=0.14).
• While not significant, the exercise group exhibited potentially favorable trends in HDLc, delta LDLc, and lower CRP levels.
• Patients in the exercise group were older, had higher LDLc, and a higher prevalence of diabetes compared to the control group.

Conclusions:

• Implementing a pre-bariatric surgery rehabilitation protocol is challenging for patients with obesity.
• The protocol may facilitate the establishment of regular and sustained physical activity.
• Further research is needed to confirm the significant impact of pre-operative exercise on muscle mass maintenance.
