(a) IMMD glutamate concentrations. Mean (±SD) intramuscular microdialysate [glutamate] ( 𝜇 M L-1) at baseline, in response to work and recovery. Percent difference in comparison to baseline is depicted on the right hand 𝑦 -axis. Significant differences with respect to baseline concentrations are indicated with * for a 𝑃 -value < . 0 5 and ** for a 𝑃 -value < . 0 0 1 . (b) IMMD PGE2 concentrations. Mean (±SD) intramuscular microdialysate [PGE2] ( 𝜇 g mL-1) at baseline, in response to work and recovery. Percent difference in comparison to baseline is depicted on the right hand 𝑦 -axis. Significant differences with respect to baseline concentrations are indicated with * for a 𝑃 -value <.05 and ** for a 𝑃 -value < . 0 0 1 . (c) IMMD lactate concentrations. Mean (±SD) intramuscular microdialysate [lactate] (mM L-1) at baseline, in response to work and recovery. Percent difference in comparison to baseline is depicted on the right hand 𝑦 -axis. Significant differences with respect to baseline concentrations are indicated with * for a 𝑃 -value < . 0 5 and ** for a 𝑃 -value < . 0 0 1 . (d) IMMD pyruvate concentrations. Mean (±SD) interstitial microdialysate [pyruvate] (mM L-1) at baseline, during work and recovery. Percent difference in comparison to baseline is depicted on the right hand 𝑦 -axis. Significant differences with respect to baseline concentrations are indicated with * for a 𝑃 -value < . 0 5 and ** for a 𝑃 -value < . 0 0 1 .
