The fencing lunge is one of the most common and fundamental attacking moves in fencing. The aim of this study was to provide kinematical compare of upper extremity among elite female and male senior fencers when performing a lunge.  Four female and four male members of Iran National Team were selected as research sample. The subjects were filmed when performing a complete lunge with a camera of 300 Hz sampling rate to record their reactions to a light stimulus. To analyze the collected data, mean, standard deviation and student's-t test at significance level of p≤0.05 were used. The results revealed that elite male fencers had significantly shorter reaction and movement time comparing with elite female fencers. No major differences in other kinematic parameters indicate that elite male and female fencers performed lunge in similar way. The final conclusion of this study is that the existing differences in time of lunge technique may suggest the need for alternative training strategies to prepare fencing athletes.

Introduction and Objective: One of the strategies that athletes can use to temporarily increase strength and muscle power is post-activation potentiation (PAP) during warm-up. However, the effect of this phenomenon on kinematics of special movement has not been determined. Therefore, the aim of this study is to investigate the acute effect of PAP during warm-up on lower extremity kinematic characteristics during heading in soccer players.
Methodology: The study sample consisted of 24 semi-professional youth soccer players with an average age of 18.67±1.11 years, height 182.32±7.12 cm, mass 74.17±7.46 kg. who performed four different warm-up methods, including PAP-take-off, PAP-landing, combined-PAP, and general warm-up, derived from the stages of soccer heading. Knee and hip angular velocities during the take-off phase, maximum knee flexion angle, and duration of knee joint pause during the landing phase were recorded using a three-dimensional motion analysis device (vicon peak ltd, oxford, vicon UK) with four T20 cameras with a frequency of 1000 Hz. Finally, analysis of variance with repeated measurements and post hoc Bonferroni test were used at a significance level of P<0.05.
Results: There was a significant increase in knee and hip angular velocities following combined-PAP and then PAP-take-off compared to other warm-up programs. Moreover, there was a significant increase in knee flexion angle after PAP-landing compared to other warm-up programs. Additionally, there was a significant increase in the duration of knee joint pause after general warm-up compared to other warm-up programs.
Discussion and Conclusion: PAP-take-off improves jumping performance, while PAP-landing improves landing performance. The combination of these two methods, i.e., combined-PAP, will yield better results overall.

Since identifying the best way of performing the Judan Mai-Mawashi-Geri technique is one of the concerns of coaches and karatekas, the aim of this study was to compare the selected kinematic variables of four methods of implementing the Judan Mai-Mawashi-Geri technique by elite male karatekas. Eighteen elite male kumite practitioners voluntarily and purposefully participated in this study. Five markers were attached to the anatomical points of the hitting foot. The four methods of implementing the Judan Mai-Mawashi-Geri technique were filmed by three Hero3 cameras at an imaging speed of 240 Hz. Using SkillSpector software (version: 1.3.2), the resultant of the peak velocity of the lower limb joints, total distance, total velocity, and total acceleration was directly obtained. The one-way analysis of variance and the Bonferroni post-hoc test (p≤0.05) were used with SPSS software (version: 22) for statistical analysis due to the normality of data distribution. The results showed a significant difference in the four methods of performing the Judan Mai-Mawashi-Geri technique in the peak velocity of the pelvic, knee, and ankle joints as well as total distance, total velocity, and total acceleration. According to the research results, the first method of implementation can be recommended as a more efficient technique to kumite practitioners due to its high speed and the possibility of scoring in the shortest time interval and because it closes the opponent’s attack route, compared with Dai and Deashi tactics.

Disruption of the homeostasis of immune regulatory mediators Aryl hydrocarbon receptor (AhR) and Ornithine decarboxylase-1(ODC-1) is involved in the pathogenesis of multiple sclerosis (MS). Physical activities play a role in controlling and improving the symptoms of MS. This study was conducted in order to investigate the effect of 4 weeks of physical activity in an enriched environment on the gene expression of AhR and ODC-1 in the cerebellum tissue of an MS mice model. This experimental study was conducted on 30 female C57BL/6 mice. Mice were divided into 3 groups of 10 including 1) healthy control, 2) experimental model of MS and 3) physical activity in enriched environment. After induction of experimental autoimmune encephalomyelitis (EAE), the third group lived in the enriched environment for 4 weeks. Body weight and clinical score were recorded daily from induction until 28 days. The gene expression of AhR and ODC-1 in the cerebellum was measured by RT-PCR method. Statistical analysis of the data was performed using one-way analysis of variance at a significance level of less than 0.05. Activity in the enriched environment significantly decreased the gene expression of AhR compared to the EAE group (P=0/02) and also decreased the gene expression of ODC-1, but it was not statistically significant (P=0/28). Also, the clinical score improved significantly after activity in the enriched environment (P= 0/001). Lifestyle change and activity in the enriched environment led to the down regulation of the gene expression of AhR and ODC-1, and it improved the clinical score of animals.

Exercise training and vegetarian diets have been accepted as suitable and non-pharmacological methods to weight loss, and improve cardiovascular factors such as blood pressure. The purpose of this study was to investigate the impact of combining aerobic exercise (AE) and vegetarian diet (VD) on blood pressure and body weight in adults with overweight and obesity. The PubMed, Web of Science, Scopus, and Google scholar databases were searched until February 2023 for English articles, and 1065 articles were found. Meta-analyses were performed to compare the impact of aerobic exercise and vegetarian diet on body weight, blood pressure in adults with overweight and obesity. Data analysis was performed using random effect model and weighted mean differences (WMD). Also, the confidence interval of 95% was considered. Also, the I² test was used to determine heterogeneity, and the Funnel plot and Egger tests at a significant level of 0.1 were used to determine publication bias. The results of meta-analysis of 25 studies with 10192 adults showed that combined aerobic exercise and vegetarian diet significantly decreased in body weight [WMD=-4.63, (CI: -5.7 to -3.56), p=0.001], systolic blood pressure [WMD=-6.94, (CI: -7.86 to -6.01), p=0.001], and diastolic blood pressure [WMD=-4.5, (CI: -5.04 to -3.96), p=0.001], in adults with overweight and obesity.  The findings of the present meta-analysis suggest aerobic training alongside vegetarian diet as a non-medication approach for weight loss and blood pressure control in adults with overweight and/or obesity. In addition, aerobic exercise and vegetarian diet with both types of duration (less than 12 weeks and more than 12 weeks) cause a significant decrease in blood pressure in adults with obesity and overweight.

With the progress of science and the revelation of the benefits of technology for human societies, sports science researchers increased their efforts to find ways to increase the optimal performance of athletes. One of the categories that has affected and transformed not only sports, but also all aspects of human life, is nanotechnology, especially nanoscience. Nanoparticles have significant effects in improving sports performance of athletes, silver and zinc oxide nanoparticles have played a role more than other nanomaterials. Therefore, this research was conducted to investigate the effect of clothes containing silver and zinc oxide nanoparticles on the sports performance of female athletes. The statistical population of the study was all women active in public sports in Maku city. The sample size was selected randomly and included 10 female athletes. The effects of treatments (sports activities with and without nano clothing) on endurance, moisture absorption, bacterial levels, high and low blood pressure, and heart rate in athletes were investigated. To determine the difference between the groups, Duncan's post-test with a probability of 0/05 was used. The results showed that the effect of silver and zinc oxide nanoparticles clothing on improving endurance of female athletes is different and increased their endurance. The effect of these clothes on the improvement of bacterial removal from the body of female athletes is different, and it increased the removal of bacteria in them. The effect of these clothes on the improvement of the blood pressure of female athletes was the same in terms of high blood pressure before training, and it did not have much effect on their high blood pressure. There was no significant difference between female athletes in terms of low blood pressure before training, and clothes containing silver and zinc oxides nanoparticles did not have much effect on their low blood pressure. There was a significant difference between female athletes in terms of high blood pressure after exercise, and clothes containing silver and zinc oxide nanoparticles were effective in reducing their high blood pressure. A significant difference was seen between female athletes in terms of low blood pressure after training and these clothes were effective in reducing their low blood pressure. The effect of clothes containing silver and zinc oxide nanoparticles on improving the heart rate of female athletes before training was not different, and it did not have much effect on their heart rate. There was a significant difference between female athletes in terms of heart rate after exercise and these clothes had an effect in reducing their heart rate. The effect of these clothes on improving the absorption of moisture in female athletes was different and it increased the absorption of moisture in them. In general, clothes containing silver and zinc oxide nanoparticles increased the sports performance of female athletes.

Lack of sensory information, muscle weakness, lack of coordination and position sense of joint are predictor factors of musculoskeletal disorders, and it seems that sports activities will have an effect on posture control and joint proprioception. Therefore, the purpose of this research was the effect of Pilates exercises on balance and proprioception in female students. 98 female students between the ages of 18-25 years-old and weight 57.92±7 kg voluntarily participated in this study after completing the written consent form. Of these, 91 healthy students were placed in the experimental group and 7 students with sports exemption (with medical conditions such as: recent surgery for refractive errors of the eye, cysts, etc.) 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. Wilcoxon test was used to determine the difference in pre-test and post-test (intra-group difference) and covariance test was used to compare between groups (of course, the data were normalized earlier). The results showed that after the intervention, 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 compared to the pre-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. According to the adjusted average in the post-test stage, 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.
