Aging-related changes in skeletal muscle. Mechanisms and interventions

Area of Science:

• Gerontology
• Exercise Physiology
• Endocrinology

Background:

• Aging leads to motor handicaps, impacting the healthcare system due to a growing elderly population.
• Impaired motor performance in old age is linked to central/peripheral nervous system and muscle tissue changes.
• Loss of muscle mass, strength, and quality significantly affects mobility, fall recovery, and independence in older adults.

Purpose of the Study:

• To explore interventions for improving motor performance in the aging population.
• To evaluate the effectiveness of physical exercise and hormone supplementation for age-related muscle decline.
• To highlight the need for further research into the safety and long-term effects of interventions.

Main Methods:

• Review of existing literature on aging, motor performance, and intervention strategies.
• Analysis of studies on physical exercise interventions for older adults.
• Examination of research on hormone supplementation therapies (growth hormone, androgens) for skeletal muscle.

Main Results:

• Physical exercise is a well-established intervention for enhancing muscle function, reducing falls, and maintaining independence.
• Hormone supplementation therapies have shown encouraging effects on skeletal muscle mass and function.
• Long-term clinical trials are required to assess the safety and efficacy of hormone treatments.

Conclusions:

• Physical exercise is a safe and effective strategy for mitigating age-related motor decline.
• Hormone therapies present potential benefits but require extensive safety and efficacy evaluation.
• Advancements in cellular and molecular techniques will aid in understanding and addressing age-related muscle dysfunction.
