In making an attempt to examine the fitness training effects on coordination and strength of preschool children, four groups of 5 year old children consisted of two experimental groups of three children for each sex and two controls of similar composition were employed. Experimental groups were subjected to one circuit of various physical activities which lasted for 30-40 minutes per day for 5 weeks. Measurements obtained in continuous tapping, whole body reaction time, grip strength and vertical jumping during those five weeks except in Sundays and national holidays were analysis method and were compared with the results of physical fitness tests.
The results were summarized as follows:
(1) The analysis of daily fluctuations in physical fitness test performances for five weeks showed that each subject had specific pattern of fluctuations in terms of different periods, amplitudes and linear trend.
(2) When compared the mean amplitudes of daily fluctuations in physical fitness tests with the mean values of increase from pre-training values, tapping was found to be the only variable with significant differences between them.
