| Results | HMB additively increased gait speed with small benefits and provided no enhancements in the effects of exercise on other outcomes. Exercise appeared to be the only effective program to improve outcomes in older women with low muscle mass. | ||||||

| Participant flow | 1. Eligibility assessment
2. Baseline survey 3. Intervention 4. Post-intervention survey 5. Observation 6. Follow-up survey |
||||||
| Adverse events | Exercise-related adverse events were not observed.
Eight adverse events, potentially related to HMB supplementation, were reported (nausea: n = 1, stomach discomfort: n = 2, whole-body discomfort: n = 1, increased urinary frequency: n = 2, pruritus: n = 1, and high blood pressure: n = 1). No significant differences in the number of participants who reported these adverse events between the HMB and placebo groups. |

| Outcome measures | 1. Muscle mass
