Effects of a Multicomponent Exercise Program in Physical Function and Muscle Mass in Sarcopenic/Pre-Sarcopenic Adults

Area of Science:

• Gerontology
• Exercise Physiology
• Geriatric Medicine

Background:

• Sarcopenia and pre-sarcopenia are prevalent conditions in older adults, leading to decreased physical function and increased risk of falls.
• Multicomponent exercise programs are proposed interventions to mitigate sarcopenia's effects.
• Standardizing exercise for community-dwelling older adults is crucial for adherence and long-term benefits.

Purpose of the Study:

• To evaluate the impact of a 12-week multicomponent exercise program on physical function and muscle mass in older adults with sarcopenia or pre-sarcopenia.
• To assess the program's potential for standardization and integration into daily life for community-dwelling older adults.

Main Methods:

• A single-blind randomized controlled trial involving 72 participants (≥60 years) diagnosed with sarcopenia or pre-sarcopenia.
• Participants were randomized into an exercise group (resistance, balance, flexibility, aerobic training) or a control group.
• Outcome measures included physical function (chair stand, timed up-and-go tests) and muscle mass, assessed pre- and post-intervention.

Main Results:

• The exercise group demonstrated significant improvements in the chair stand test (p=0.02) and the timed "up and go" test (p=0.01).
• While a trend towards preserving muscle mass was observed, no significant changes in cross-sectional muscle area or volume were found.
• A high completion rate (93.1%) indicates good adherence to the 12-week program.

Conclusions:

• A 12-week multicomponent exercise program effectively enhances physical function in older adults experiencing sarcopenia or pre-sarcopenia.
• The program shows promise as a therapeutic intervention for improving mobility and functional independence in this demographic.
• Further research is needed to confirm its efficacy in increasing muscle mass.
