Abstract
The purpose of the present study was to study the effect of attentional focus instructions on motor skills that requiring near to maximum force production, such as shot put skill. In this experiment, twenty eight right- handed girl students with little shot put experience were selected voluntarily. They divided to two groups (internal and external focus) based on their shot put scores in pre- test (consists of 3 trial). They were asked to shot put using O׳brien technique. Experiment performed in three sessions and each session consists of three trials. Instructions referred specifically either to body movement (internal focus) or to shot (external focus). In this study, mixed ANOVA 2(group) ´ 3(session) with repeated measures on last factor is used for analyzing data. The results of this experiment showed that distance of shot put was greater in external focus group rather than internal focus group. Also interaction between attentional focus and practice session was significant (P< 0/001). In conclusion, external focus resulted in producing greater force relative to internal focus. These findings indicate that previously shown benefits of an external attentional focus generalize to motor skills requiring maximal force production.

Abstract
The purpose of this study was to determine the effect of exercise and fitness education on physical fitness factors. 84 healthy non-athlete student (mean age 12.5±0.49 yrs, mean height 153.8±6.1 cm, mean wieght 46.25±7.3 kg) who had not regular activities for more than 6 months were voluntarily participated in this study. They were randomly divided among three groups: training-education (n=28), training (n=28) and control (n=28). The health-sports, the researcher made scientific the Dessi-Ryan motication questionaires and health-relaeted physical fitness factors were used to collect data. To analyse data MANOVA, simple variance analysis and LSD were used. Results showed a significant differences among groups. The follow-up test results showed that the cardio-respiratory endurance in training-education group were significantly greater than other groups. Flexibility and abdominal endurance muscles in control group were lesser than other groups. In conclusion, training along with education can have a better effect on physical fitness factors.
