A multicomponent intervention consisting of exercise, proteins and omega-3 supplementation to improve sarcopenia in community-dwelling older adults: Lessons learned from a 5-armed randomized controlled feasibility trial.

A multicomponent intervention combining exercise, proteins, and omega-3 supplementation to treat sarcopenia showed low feasibility, moderate acceptability, and high safety, with preliminary efficacy results suggesting exercise with protein supplementation may improve physical function and that adding omega-3 PUFA might offer further benefits for muscle strength and mass.
Key Findings
Methods
The ENHANce feasibility trial enrolled 58 community-dwelling older adults with sarcopenia across five intervention arms.
Participants were aged 76.2±6.6 years, with 65.5% female
Groups were: Exercise (n=9), Protein (n=12), Exercise+Protein (n=13), Exercise+Protein+Omega-3 (n=12), and Control (n=12)
Participants were diagnosed with sarcopenia using EWGSOP2 criteria
The trial was a parallel five-armed randomized assessor-blinded controlled feasibility trial with triple-blinded supplementation
The intervention duration was 12 weeks
Results
Feasibility of the multicomponent sarcopenia intervention was low, with a recruitment rate of only 2%.
The recruitment rate was reported as 2%
Feasibility was assessed via eligibility, recruitment, retention, and data completion rates
The overall feasibility was characterized as 'low' by the authors
Results
Acceptability of the multicomponent intervention was moderate, with participants reporting positive experiences but also notable challenges.
Most participants completed the planned assessments
Participants reported positive experiences such as feeling stronger and more aware of the importance of physical activity and nutrition
Many participants found the study procedures demanding
Many participants experienced difficulties with the protein supplements
Adherence varied widely across interventions
Results
The multicomponent intervention demonstrated high safety, with no significant adverse effects reported across any of the five study arms.
Safety was assessed across all intervention groups including exercise, protein, and omega-3 supplementation arms
No significant adverse effects were reported during the 12-week trial
Safety was described as 'high' by the authors
Results
The interventions showed potential to improve chair stand test (CST), Short Physical Performance Battery (SPPB), muscle mass, and quadriceps strength.
Preliminary efficacy results indicated that exercise with protein supplementation may improve physical function
Outcomes measured included chair stand test (CST), Short Physical Performance Battery (SPPB), muscle mass, and quadriceps strength
Adding omega-3 PUFA to exercise and protein supplementation might offer further benefits for muscle strength and mass
These findings are considered preliminary and require confirmation in larger studies
Measurements were taken after 12 weeks of intervention
Methods
The study was a home-based individualized intervention combining exercise, proteins, and/or omega-3 polyunsaturated fatty acids (PUFAs) supplementation targeting community-dwelling older adults with sarcopenia.
Exercise was individualized and home-based
The intervention combined physical exercise, protein supplementation, and omega-3 PUFA supplementation in various combinations across arms
Participants were community-dwelling older adults aged ≥65 years
Sarcopenia diagnosis followed EWGSOP2 criteria
The study was registered on ClinicalTrials.gov (NCT03649698) as the ENHANce (Exercise and Nutrition for Healthy Ageing) study
