Studies have shown a significantly increased rate of fatigue development during both low, and
high intensity work [2, 3]. Numerous researchers have also reported that acute hypoxemia
exaggerates the rate of fatigue development, centrally [4, 5, 6, 7] and peripherally [7, 8, 9, 10, 11,
12]. While abundant research exists on cold and hypoxic stressors separately, the interactive
effects of combined exposure on the rate of muscle fatigue development remains unexamined.
We hypothesised that relative to baseline performance levels, independent exposure to arterial
de-oxygenation and systemic cooling will induce a significant increase on post exercise fatigue,
compared to values observed during thermoneutral normoxia. During combined hypoxic-cold
exposure, we expected a significant synergistic interaction on post exercise fatigue, with
peripheral blood flow reductions during cold accentuating the fatiguing effect of low arterial
oxygenation.
