Abstract
Different postural stability and functional movements may play an important role in secondary injuries in people with flexible flatfeet compared to people with normal feet. However, the difference between static and dynamic stability and functional movements of people with and without flexible flatfeet has not been investigated. This study compared static and dynamic stability and functional movements of subjects with and without flexible flatfeet and examined the relationship between functional movements and static and dynamic stability. 96 subjects (flexible flatfeet group: 25; normal feet group: 71) functional movement screening test (FMS); Sharpened Romberg balance test and Y balance test were performed. The scores of functional movements and static stability in the normal feet group were significantly higher than the flexible flatfeet group (p≤0.05). The total score of the Y test was not significantly different between the two groups (p≥0.05). In the group of normal feet, a significant correlation was observed between functional movement scores and dynamic stability (p≤0.05). These results show that subjects with flexible flatfeet have different movement performance and static stability compared to subjects with normal feet, but they have similar dynamic stability. It may indicate that there is no connection between static and dynamic stability and these two functions are separate from each other.

Abstract
This systematic review aimed to investigate the effectiveness of resistance training, particularly exercises designed based on 3D motion analysis, in improving muscle strength and balance function in elderly individuals with early knee osteoarthritis. A comprehensive search was conducted in PubMed, PEDro, Scopus, and Web of Science databases for articles published from January 2000 to December 2024. Selected studies were required to have utilized 3D motion analysis to assess movement deficits and design exercise programs. Out of 84 reviewed articles, 18 were chosen for final analysis. The results indicated that the majority of studies (86%) confirmed the effectiveness of resistance training in ameliorating knee osteoarthritis symptoms. Specifically, significant improvements were observed in functional balance (44% of articles) and reductions in knee pain (48% of articles). Furthermore, 33% of the studies reported superior efficacy for exercises designed based on 3D biomechanical analysis. These findings can significantly enhance the quality of life for patients and promote mobility safety in the elderly by reducing the risk of falls and improving joint stability. In conclusion, the findings suggest that innovative training approaches, particularly those incorporating 3D motion analysis, can play a pivotal role in optimizing rehabilitation and enhancing the quality of life for elderly individuals with knee osteoarthritis.

Abstract
Aim: Optimal performance is the ultimate goal of athletes. The purpose of this study was to compare the effects of different high-intensity interval training (HIIT) protocols on athletic performance and metabolic adaptations. Methodes: The participants were divided into 4 groups: High-Intensity Running Training (HIITRUN), Sport-Specific High-Intensity training (HIITSPORT), Combined Training (HIITSPORT+RUN), and Control. The measured indicators included: maximum running speed in the 30-15 test (VIFT), maximum oxygen consumption (VO2max), the SWFT index and throws in the sport-specific wrestling fitness test, fatigue index, and maximal lactate. Comparisons between dependent variables were performed using a two-way analysis of variance (group and time) with repeated measures. Result: Significant changes in (VIFT) and VO2max were observed in HIITSPORT+RUN (P<0.05) and HIITRUN (P<0.05) compared to pre-training, control, and HIITSPORT. The fatigue index showed a significant decrease in HIITSPORT+RUN and HIITRUN compared to pre-training in the other groups. HIITSPORT+RUN (P<0.05) showed the greatest improvements in the SWFT index compared to HIITRUN and HIITSPORT, and the time-group interaction confirmed its superiority. Post-exercise lactate levels in HIITSPORT+RUN (P<0.05) were lower than in HIITRUN, but no significant difference was observed in the time-group interaction (P<0.05). The difference in maximal lactate levels before and after exercise in HIITSPORT+RUN (P<0.05) was lower compared to HIITRUN. HIITSPORT+RUN (P<0.05) showed better performance in the SWFT compared to pre-training. The fatigue index decreased in all training groups except for the control (P<0.05). Conclusion: the combined HIIT approach of sport-specific training and running is the most effective method for improving wrestlers' performance and metabolic adaptations.

Abstract
The aim of this study was to Compare Effectiveness motor proficiency of the nutritional status on men in different age groups ((children, adolescents and young adults)), respectively. Statistical Society study was for children all student ages 10-7 years, for adolescents all student ages 15-12 years and for Youth of all students 20-18 of Tehran University except the student physical education. The sample was 90 people in each of the age groups, the four elementary schools and four high schools in Tehran and Tehran University male students were chosen by cluster sampling. This study was a descriptive survey and comparison measurement was test of instruments anthropometric and Brvnynks- Oseretsky. The results showed that among malnutrition, moderate nutrition and proper nutrition in adolescence and adulthood motor proficiency was not statistically different ages but among children ages motor proficiency were significantly different. In addition, no significant difference between motor proficiency age groups. It seems due to the impact of nutritional status on motor proficiency, and this issue was observed in this study at an early age; therefore, children are the most vulnerable in this context and considering the nutritional status of children is very important.

Abstract
The purpose of this research was the effect of Pilates exercises on balance and proprioception in female students. 98 female students voluntarily participated in this study. Of these, 91 healthy students were placed in the experimental group and 7 students with sports exemption were placed in the control group. The position senses of ankle and knee joints was measured using the active reconstruction test of the ankle and knee angles and static balance was measured using the Sharpened Romberg test before and after 16 intervention sessions. The results of Wilcoxon test showed that in the experimental group, static balance increased significantly in the post-test compared to the pre-test. The position sense of dorsiflexion, plantarflexion of ankle joint and knee flexion position sense in the experimental group increased significantly in the post-test. Also, the results of the covariance test showed that there is a significant difference between the two groups in the post-test in the variables of static balance and position sense of dorsiflexion and plantarflexion of ankle and position sense of knee flexion that according to the adjusted average, the experimental group performed better than the control group. The results showed that Pilates exercises are suitable for improving ankle and knee proprioception and improving postural control in teenagers and young adults.
