Experimentální: Tocilizumab
Participants will receive one 30 min intravenous infusion of tocilizumab/Actemra® (Roche).
The dose will be 8 mg/kg bodyweight or a maximum of 800mg.
Tocilizumab is dissolved in 100 mL 0.9% saline.
|
The infusion of tocilizumab will antagonize IL-6 signaling for the duration of the study, allowing us to determine the role of IL-6 in regulating energy stores following acute exercise
|
|
Komparátor placeba: Saline
As placebo, participants will receive one 30 min intravenous infusion of 100 mL 0.9% saline.
|
The infusion of saline will serve as placebo for tocilizumab, allowing us to determine the role of IL-6 in regulating energy stores following acute exercise
