Sarcopenia in the Aging Process: Pathophysiological Mechanisms, Clinical Implications, and Emerging Therapeutic...

Area of Science:

• Gerontology
• Muscle Physiology
• Inflammammation Biology

Background:

• Sarcopenia, characterized by muscle loss, is a growing concern in aging populations.
• It is linked to chronic inflammation, oxidative stress, and mitochondrial dysfunction, contributing to comorbidities like type 2 diabetes and obesity.
• Current interventions need better integration to target these interconnected mechanisms.

Purpose of the Study:

• To review and synthesize recent evidence on interventions for sarcopenia in older adults.
• To evaluate the efficacy of multicomponent strategies targeting muscle function and inflammation.
• To integrate knowledge on resistance exercise, nutritional supplementation, and probiotics.

Main Methods:

• Systematic literature review and critical analysis of studies on sarcopenia interventions.
• Focus on resistance exercise, high-protein intake, leucine, vitamin D, omega-3 fatty acids, and probiotics.
• Evaluation of effects on muscle strength, function, inflammatory status, and mitochondrial function.

Main Results:

• Combined interventions, particularly resistance training with anti-inflammatory nutrition and supplements, show significant benefits.
• Improvements observed in muscle strength, reduced pro-inflammatory cytokines, and enhanced mitochondrial function.
• Multicomponent strategies are more effective than single interventions.

Conclusions:

• An integrated, multicomponent approach is a promising strategy for managing sarcopenia.
• This approach can attenuate sarcopenia progression and reduce associated comorbidities.
• Further research should focus on optimizing combined intervention protocols.
