Regular Daily Exercise Improves Sarcopenia in Elderly Patients.

In 30 seconds

This 12-week randomized controlled trial assessed multicomponent exercise in adults aged 60–75 years with sarcopenia. Participants were assigned to control or postprandial resistance and aerobic training for 37 minutes per session, 3 days per week; 94 were analyzed. At week 12, the exercise group had a higher Modified Barthel Index than controls (68.89 ± 9.60 vs. 62.02 ± 10.35; p = 0.001), alongside better muscle, mobility, and inflammatory measures. The findings suggest that regular exercise can improve functional independence and other measured outcomes in this population over 12 weeks.

Key findings

• At week 12, Modified Barthel Index scores were 68.89 ± 9.60 with exercise and 62.02 ± 10.35 with control (p = 0.001).
• Appendicular skeletal muscle mass index was 6.074 ± 0.904 vs. 5.295 ± 0.739 kg/m 2 (p < 0.001), and handgrip strength was 22.78 ± 5.02 vs. 19.95 ± 4.25 kg (p = 0.009).
• The exercise group had better 6-minute walk test results (395.6 ± 55.6 vs. 363.7 ± 53.8 minutes; p = 0.005) and shorter Timed Up and Go times (6.76 ± 1.41 vs. 7.66 ± 1.55 seconds; p = 0.005).
• IL-6 and TNF-α levels were lower with exercise than control: 45.21 ± 10.66 vs. 53.73 ± 10.99 pg/mL and 38.09 ± 8.64 vs. 45.45 ± 8.07 pg/mL, respectively (both p < 0.001).

Why it matters

Sarcopenia can compromise mobility and independence in older adults. This trial reports improvements across functional independence, muscle measures, physical performance, and inflammatory markers after a structured exercise program. The results add randomized evidence that a nonpharmacological intervention may address several clinically relevant dimensions of sarcopenia, although the findings reflect outcomes measured over a 12-week period.

What to keep in mind

Although 224 participants were enrolled, 120 were randomized and 94 were analyzed. Outcomes were assessed at baseline and week 12, so longer-term effects are not established.
