The purpose of this study is to show the effects of aquatic training with high school soccer player on in-step shooting speed and accuracy of kick, muscle strength of lower extremities and balance. The subjects of this study were 9 high school-soccer players with a career more than 6 years and they participated in aquatic training for 8 weeks before and after, that the study consist of in-step shooting speed, accuracy of in-step kick, isokinetic strength of ankle and knee joint and balance. We used SPSS 12.0 in order to analyze the results through the research, and compared the measurement subject by using the standard deviation of the mean. In addition, we did paired 2-sample non-parametic test for comparison of variables before and after the experiment and Spearman`s Bivariate Correlation Analysis for relationship of respective variables. The level of significance is set up to 0.05 The results of the study were as follows; 1. In the shooting speed was significantly differentiated pre and post-test(p<.05). 2. In the accuracy of in-step kick was significantly differentiated pre and post-test(p<.05). 3. In the muscle strength of knee flexor and extensor were improvement pre and post but not significantly differentiated. In the muscle strength of ankle dorsiflexor and plantarflexor were significantly differentiated(p<.05). 4. In the one leg standing, muscle strength of the left leg was improvement but not significantly differentiated and the right leg was significantly differentiated(p<.05). 5. Right ankle plantarflexor was significantly differentiated with exercise performance of in-step kick pre and post(p<.05), balance was significantly differentiated with high and mean speed pre and post(p<.05). Therefore, based on the result, it is indicated that the aquatic training had a positive effect on the shooting speed, accuracy of kick, muscle strength of lower extremities and balance. It is considered that give helps to improve ball speed and accuracy.

Purpose: A cost effective tool for the clinical measurement of trunk reposition sense is clearly needed. This study was to analyze intrarater and interrater Reliability of trunk repositioning error (TRE) test which assesses trunk position sense using a portable digital inclinometer. Methods: Twenty four normal healthy subjects were recruited. TRE was measured using a portable digital inclinometer. A digital inclinometer (Acumar-ACU360; Lafayetter Instrument) with precision to $1^{\circ}$ was placed on skin over the spinous process from first to second thoracic vertebra (T1-T2) and secured with double-sided tape. TRE test during sitting forward and lateral flexion movement was assessed. When they reached a point approximately 50% of full trunk flexion range, the examiner instructed the subjects to stop and told them. This was the target position that they should try to reproduce exactly. Each subject performed six trials. Results: ICC (2,1) for intrarater reliability (with-day and between-day) of TRE test in sagittal and frontal plane of movement was 0.75 and 0.78 (excellent reliability). Interrater reliability was 0.66 in sagittal and 0.64, frontal plane (fair to good reliability). However, there were poor correlations between an average of TRE test in sagittal and frontal plane. Conclusion: TRE test using a portable digital inclinometer demonstrated good to excellent reliability. The device may be a cost effective clinical measurement for trunk reposition sense measurement.

Purpose Over the last few decades, awide range of exercises have been shown to provide hemiplegic patients a more stable and dynamic balance. Moreover, core stability exercises for hemiplegic patients after a stroke have become increasingly significant in rehabilitation units. Method This study examined the therapeutic effects of the core stability exercises on the static and dynamic balance of hemiplegic patients. A total of 10 hemiplegic patients (4 males, 6 females, age ranging from 37 to 81 years) were enrolled in this study. The subjects in the experimental group participated in the core stability exercise program consisting ofa total of 12 sessions 3 times per week, over a 4-week period with each exercise lasting forapproximately 15 minutes. Result The static and dynamic balance by the Berg Balance Scale (BBS) and Timed Up and Go (TUG), respectively, were measured before and after the core stability exercises. A Wilcoxon signed ranks test and Mann-Whitney U test were used to compare the static and dynamic balance before and after the core stability exercises in the hemiplegic patients in each group and inter-groups, respectively. Conclusion The core stability exercises were relatively effective in improving the static balance; BBS. The core stability exercises were quite effective in improving the dynamic balance; TUG (p<.05). Overall, core stability exercises are believed to be an important therapeutic method in rehabilitation programs for hemiplegic patients.
