Exercise improved grip and gait in older adults with sarcopenia; added nutrition did not add much

Design

Three-arm cluster randomised controlled trial, one cluster per arm

Population

90 community-dwelling Vietnamese adults aged 60 to 70 with sarcopenia

Primary outcome

Muscle mass, handgrip strength and gait speed at 24 weeks

Effect

Handgrip +2.49 kg (exercise) and +2.23 kg (combined); gait +0.206 m/s (exercise only)

This three-arm cluster randomised trial in Can Gio, Vietnam, assigned one community each to health education, exercise, or exercise plus nutrition support, with 30 adults aged 60 to 70 with sarcopenia per community. Exercise combined aerobic and resistance training for 24 weeks, supervised weekly for the first 12. The combined arm also received nutrition counselling and a daily supplement (270 kcal, 11 g protein) for 12 weeks.

At 24 weeks, both active arms improved handgrip strength compared with control (2.49 kg and 2.23 kg). Only the exercise-alone arm improved gait speed (0.206 m/s) and skeletal muscle index (0.12 kg/m²).

The result supports exercise as the core of sarcopenia management in community settings similar to rural India. With one community per arm, however, community and treatment effects cannot be separated, and the trial was registered retrospectively, so the lack of benefit from added nutrition should not be over-interpreted.

• Prescribe progressive resistance and aerobic exercise as the core treatment for sarcopenia.
• Measure grip strength and gait speed to track response.
• Check dietary protein intake and correct deficiency, even though the supplement here added little.
• Build supervised exercise into the first 12 weeks before moving to home practice.

Why it matters

It is community-based evidence from a lower-middle-income setting where sarcopenia care is often unavailable.

Don't overread it

One community per arm, so treatment and community are confounded; the nutrition finding is not definitive.

The statistics, in plain English

A gait speed gain of about 0.2 m/s is above the roughly 0.1 m/s often treated as clinically meaningful; a 2.5 kg grip gain is modest. The combined arm's gait interval (−0.017 to 0.123) crosses zero, so that arm showed no clear gait benefit.
