Maintained cerebral oxygenation during maximal self-paced exercise in elite Kenyan runners.

Journal of applied physiology (Bethesda, Md. : 1985):jap.00909.2014.

The purpose of this study was to analyze the cerebral oxygenation response to maximal self-paced and incremental exercise in elite Kenyan runners from the Kalenjin tribe. On two separate occasions, 15 elite Kenyan distance runners completed a 5-km time trial (TT) and a peak treadmill speed test (PTS). Changes in cerebral oxygenation were monitored via near-infrared spectroscopy through concentration changes in oxy- and deoxy-hemoglobin (Δ[O2Hb] & Δ[HHb]), tissue oxygenation index (TOI) and total hemoglobin index (nTHI). During the 5-km TT (15.2 ± 0.2 min), cerebral oxygenation increased over the first half (increased Δ[O2Hb and Δ[HHb]) and, thereafter, Δ[O2Hb] remained constant (Effect siz
