The purpose of present study was clarified to the physiological response to
walking
for a long term at moderate altitude (1450m). The healthy 6 males participated experiment as a subject in this study. They performed
walking
of steady state velocity( 80m/min) for 60min in either sea level(64m: SL) and moderate altitude(1450m; MA). Respiratory metabolism, heart rate(HR), perceived of exertion(RPE),arterial O2 saturation(SpO2) , blood lactate( BLa) and blood glucose( BGlu) were measured during 60 min
walking
. SpO2 was significantly lower in the MA than in the SL (P<0.01). HR, Oxygen uptake, and RPE did not differ between the two conditions. However, respiratory exchange ratio was significantly higher for MA than SL at the end of the
walking
test(P<0.05). Furthermore, BLa did not change after the
walking
test, but BGLu decreased significantly only in MA (P<0.05). It is concluded that physiological response in
walking
at moderate altitude showed energy supply was more dependent on the glycolytic system due to the influence of hypobaric hypoxia.
