Short-Term Multicomponent Exercise Impact on Muscle Function and Structure in Hospitalized Older at Risk of Acute...

Area of Science:

• Geriatric Medicine
• Rehabilitation Science
• Aging Research

Background:

• Hospitalization accelerates sarcopenia and physical decline in older adults.
• The efficacy of inpatient exercise in preventing acute sarcopenia is not well-established.
• This study investigated a tailored multicomponent exercise program for hospitalized older adults.

Purpose of the Study:

• To determine the effect of a brief, tailored inpatient exercise program on muscle and physical function in older adults.
• To test the hypothesis that exercise would attenuate muscle function and structure changes compared to usual care.

Main Methods:

• A randomized clinical trial involving 130 patients aged 75+ admitted to an acute care geriatric unit.
• Participants were assigned to a 3-5 day tailored exercise program or usual hospital care.
• Primary outcomes included changes in Short Physical Performance Battery (SPPB) score and gait velocity.

Main Results:

• The exercise group showed significant improvements in SPPB scores and gait velocity compared to the control group (p < 0.01).
• No significant differences were found in muscle or fat architecture as assessed by ultrasound.
• No adverse events related to the study were reported.

Conclusions:

• A brief, tailored multicomponent exercise program can provide functional benefits for hospitalized older adults.
• The exercise intervention did not alter muscle or fat architecture within the study duration.
• Inpatient exercise may be a viable strategy to mitigate acute sarcopenia in vulnerable older populations.
