    The purpose of this study was to investigate the physiological and morphological characteristics of skilled long-distance runners in uphill running to employ the index of aptitude in uphill running. Eight long-distance runners were measured for body composition, girth, muscle thickness, jumping ability, leg power-force and aerobic capacity (velocity/work rate@ OBLA, maximum oxygen uptake). It was no correlation between value of uphill running aptitude index and body composition, girth, muscle thickness, jumping ability and leg power-force. While level running velocity at OBLA was not correlated with aptitude index in uphill running, maximum oxygen uptake was correlated with uphill running aptitude index. Additionally, pedaling power at OBLA and maximum oxygen uptake using a bicycle ergometer were correlated with uphill running aptitude index. In conclusion, skilled uphill running long-distance runners have higher ability of aerobic energy production and muscle endurance in lower limbs.
