| Supplementation status | |||
|---|---|---|---|
| Tyrosine | Non-supplementation1-150 | ||
| Phenylalanine (μmol/l) | 806.3 (280.8) | 780.65 (174.4) | |
| Tyrosine (μmol/l) | 55.0 (24.3) | 42.3 (7.8) | |
| Phenylalanine:tyrosine ratio | 18.1 (6.4) | 20.0 (7.3) | |
↵1-150 Non-supplementation consists of the average of performance during baseline and l-alanine phases.
