- Baseline and theoretical values are presented as mean ± pooled S.E. values and were derived from Table 1.
- TCr = Total creatine
- PCr = Phosphocreatine
- Cr = Creatine
- ATP = Adenosine triphosphate
- † Younger participants were between the ages of 18-36 years old, whereas older participants were between the ages of 52-79 years old.
- ‡ All of the referenced interventions supplemented subjects either through a loading phase (i.e., 20 g/d for 5 days) or through a 14-to-24 week supplementation protocol using 5 g/d.
- §= Significant difference between young and old, p < 0.05.
- * = Signifies a theoretical significant difference between young and old, p < 0.05.
