ABSTRACT
Soccer players move in many directions and at various speeds during a match. The movements in the field are dependent on their various physiological abilities such as aerobic power, anaerobic power and so on. In order to design proper training programmes for soccer players, an estimate of the distribution of the ratios of physiological intensities is needed. Reilly and Thomas (1976) reported that the percentage of the distance covered at the individual's top speed was 11.2% of the total distance. Withers et al. (1982) reported that it was 18.8%. Mayhew and Wenger (1982) reported that 11.3% of the total match time was at the highest speed. Yamanaka et al. (1988) reported that it was between 7 and 10%. As these investigators estimated the distance covered and the time spent by the use of pre-determined modes of players' movement, such estimations seem to reduce the precision or objectivity of the data.
