Abstract: ABSTRACT \nMale subjects are invariably used to study the physiological determinants of middle \ndistance running performance. Studies that do include females have examined only the \naerobic contribution to middle distance running performance. The aim of the present \nstudy was to investigate aerobic, anaerobic and muscle function factors that could be used \nto predict middle distance running performance in female runners. This study was \nperformed at an altitude of 1800m. \nEleven middle distance female runners aged 18-20 were selected for the study. \nAerobic capacity was assessed by measuring the maximal oxygen consumption \n(VO2max), running velocity at maximal oxygen consumption (vVO2max), running \neconomy (RE) and onset of blood lactate accumulation (OBLA). \nThe blood lactate curve of each subject was constructed by relating the oxygen \nconsumption, to the plasma lactate concentrations. \nAnaerobic capacity was determined by measuring the maximum accumulated oxygen \ndeficit (MAOD) on a treadmill. Muscle function was assessed by having the subjects \ncycle as fast as possible against changing brake weights ranging from heavy to light using \na Monark cycle ergometer. The brake force (kg) was related to velocity (rpm).
