Abstract
The purpose of present study was to investigate predictions of challenge point theory (guadagnoli and lee, 2004) through comparing two group of challenging and nonchallenging games in developing manipulative fundamental movement skills. Thirty 4 to 6 years old child were selected from one of the kindergartens of Tehran and were grouped according to pretest scores. The games were used were designed for developing manipulative skills in both groups, however the task difficulty of these games was increased in challenging group while in nonchallenging group it was kept constant. The intervention was 8 weeks, 2 session for each week and 42 minutes for each session. Children's manipulative skills were assessed using Test of Gross Motor Development – second version in the beginning and the end of the intervention. The results of multivariate analysis of variance showed that improvement groups in total score of manipulative skills and all subscales exept that catching wasn't significant. In total, if the challenge point theories predictions on developing of manipulative skills of healthy children failed to be proved but better improvement of challenging group in catching shows that this method is more effective in developing complex skills.

Abstract
The aim of this study was to investigate the effect of physical maturity and chronological age on the motor abilities of students aged 7-12 years. 600 students aged 7-12 years were selected in three age categories. To determine the state of physical maturity, the estimation of the percentage of adult height obtained at a certain age was used. Finally, the motor ability test was used to assess motor ability. The results of the present study showed that the effect of chronological age was significant for the variable of motor abilities in girls and boys studied. Also, the effect of maturity level was significant for the variable of motor abilities. Comparison of means showed that students born at normal maturity levels have higher mean motor ability than students born at early and late maturity levels. According to the results of the present study, the level of maturity has a significant effect on the performance of motor skills. Finally, the results of this study are limited to the current population and limited to the age range of 7-12 years in Tehran and do not represent all age groups.

Abstract
The purpose of this research was to investigate the effect of manipulation of task constraints on functional indicators and cognitive status of the elderly. In this research, 30healthy elderly were randomly selected and placed in two intervention and control groups. Analysis of covariance was used to evaluate the homogeneity of the slope of the regression line and to compare the mean of the pre-test and post-test data. Data analysis was done using SPSS software. The results showed that the application of the exercise protocol for manipulation of task constraints improved strength(P=0.006), cardiovascular endurance(P=0.010), agility(P=0.001), composition(P=0.003) and Mental status(P=0.002) of the elderly in the intervention group. In addition, the results indicate that the flexibility of the control group decreased significantly from the pre-test to the post-test(P=0.007). The results of the analysis of covariance by removing the effect of the pre-test showed that the body composition variable did not differ significantly from the pre-test to the post-test stage(P=0.264). It seems that exercises with the manipulation of task constraints are effective on the performance and cognitive indicators of the elderly. Therefore, it is suggested to consider the exercises with the manipulation of task constraints to improve the quality of life of the elderly.
