Table 2 Intramuscular metabolites prior to and at the end of the first and fourth period of muscle contraction. All metabolites are mmol kg-1 dry muscle. *indicates significant change from rest, P < 0.05. †indicates significant difference between period 1 and period 4, P < 0.05. For phosphocreatine, the difference between period 1 and period 4 resulted in a p value of 0.051.
