| Methods |
Open, controlled study |
| Participants |
3 adults (age and sex not specified)
3 controls (age, sex, height and weight matched) |
| Interventions |
Baseline assessments were performed after fasting, 100 g of oral dextrose or 0.33 mg/kg branched‐chain amino acids. Participants were assessed after 1 and 2 months of 0.3 g/kg of dietary branched‐chain amino acids as a supplement to their habitual diet |
| Outcomes |
Maximal concentric strength or torque at 60 cycles per minute and muscle endurance measured as absolute work performed to fatigue (60 or 90 cycles per minute with a 2 minute rest between sets) |

| Risk of bias |
| Bias |
Authors' judgement |
Support for judgement |
| Random sequence generation (selection bias) |
High risk |
The method of sequence generation was not described |
| Allocation concealment (selection bias) |
High risk |
There was no allocation concealment |
| Blinding (performance bias and detection bias)
All outcomes |
High risk |
There was no participant or observer blinding |
| Incomplete outcome data (attrition bias)
All outcomes |
Low risk |
Data were complete for each intervention |
| Selective reporting (reporting bias) |
Low risk |
Data from each intervention were equally reported; outcomes were reported as specified in methods |
| Other bias |
Low risk |
No other source of bias identified |
