Psychological and educational findings show that preschool years play a very
important role in educating and developing children. One of the dimensions of
development is motor development. The survey of motor performance with respect
to anthropometric characteristic is of utmost importance. Thus, the aim of this
study was to survey the relationship between dimensional anthropometric
characteristic and motor performance and to determine the difference in motor
performance in all preschool children from Shiraz city (157 boys and girls aged
between 3 and 6). The method of this research was analytical descriptive.
Demographic information form, (AC) recording sheet and motor performance test
were used to collect data. One-way ANOVA, Pearson correlation coefficient and t
test were used to analyze the data. The results showed significant differences
between girls and boys in vertical jump (F=25.47, df=2, P?0.000) and horizontal
jump (F=14.15, df=2, P?0.000). 5-year-old subjects were stronger in vertical jump
and 4-year-old subjects in horizontal jump. Also, boys were better in vertical jump
(t=1.70, df=155, P?0.008) and ball throwing (t=1.98, df=155, P?0.030). In
investigation of the relationship between dimensional AC and motor performance,
weight and length dimension showed the highest relationship. The results showed
the gradual increment of muscular strength parallel with age. Gender difference
observed in some variables necessitates more research. It is suggested that other
samples and tools be used in anthropometric characteristics.

In this study, the effect of cognitive load (CL) training on duration and accuracy of bimanual coordination (BC) task was investigated. For this purpose, athletic male students of Shiraz University were randomly divided into 4 groups: G1 with low CL, G2 with intermediate CL, G3 with high CL and G4 control. The subjects practiced for 6 weeks, 3 sessions a week, 6 blocks, 12 trials. The subjects performed bimanual coordination task by Vienna test system (v=71%-84% and r=85%-96%). Independent T test and one-way ANOVA were used to analyze the data. The results showed that high CL affected the accuracy of bimanual coordination task. No significant difference was observed between CL groups and control group in overall duration (?=0.05). It can be concluded that if there is high CL in activities which require much attention, attention capacity may change and in skills that need attention, the task can be improved after information processing as a result of capacity change.
