Sternohyoid power-load relationship following 6 weeks of normoxia and sustained hypoxia ± chronic antioxidant supplementation. Sternohyoid specific power (mean ± SEM) expressed as Watts/CSA (cm²) as a function of load expressed as a percentage of peak force (force/peak force^*100); n = 5–7 per group; Ctrl, normoxic control; Hyp, sustained hypoxia (FiO₂ = 0.1); Tempol, tempol + sustained hypoxia; NAC, NAC + sustained hypoxia. P-values shown for two factor (treatment × load) analysis of variance highlighting a significant effect of 6 weeks of sustained hypoxia on sternohyoid power-load relationship. Antioxidant supplementation reversed the effects of hypoxia.
