Abstract
Improving the quality of athletes' performance and identifying the ways to optimize the performance of sports activities has always been one of the concerns of sports managers and athletes, especially in the professional and championship dimensions. 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.

Abstract
Introduction: The purpose of the present study is to introduce and examine several genes that are related to people's sports performance and can be effective in their selection and selection in their favorite sports field. Various factors of physical fitness and training ability have been investigated along with the risk of sports injury and mental fitness of athletes.
Findings: The sports performance of people and the monitoring of sports exercises have been influenced by the vast genetic map and environmental interventions. In the present study, the performance of the aerobic system with the ACE gene and its different alleles, the strength and power performance of people with the ACTN3 gene, and the risk of injury of people with different genes such as COL1A1, COL5A1, Tenascin (TNC), apolipoprotein E and blood groups were investigated. It is a prediction; also, the trainability and mental preparation of people in the talent search process can be predicted and possibly measured by genetic knowledge. On the other hand, using the knowledge of genetics and genetic profiles of athletes can be useful for detecting genetic and cellular doping and help organizations that work in the prevention of doping, such as WADA.
Conclusion: The combination of genetic knowledge and environmental interventions play an effective role not only in discussing an athlete's talent, but also in monitoring and improving their performance. While genetics can play a significant role, the prediction of sports success based on genetic knowledge has been limited to a specific set of genes. However, developing this knowledge and identifying more genes that can aid in talent identification and exercise monitoring requires further research.

Abstract
This study aimed to assess the effects of acute calcium lactate supplementation intake on the performance and buffering capacity of elite amateur boxing athletes. 8 elite amateur boxers (180±4.33 cm, 24.12±3.68 years, Weight categories: -75, -64, -69, +81) were assigned to acutely receive calcium lactate (0.5 g, 80 mg calcium lactate/kg body weight) and placebo in a double-blind crossover design 90 minutes before the box competition. 90 minutes before, before competition and immediately after, blood samples were taken and lactate, PH, HCO3-, and PCO2 and also, average heart rate, and number of effective hand kick were evaluated. lactate and HCO3- significantly increased and decreased at three evaluation times in calcium lactate supplementation and placebo groups respectively (P<0.05). There was no significant difference between calcium lactate supplementation and placebo groups in lactate, pH, HCO3-, PCO2, heart rate and performance at three evaluation times (P>0.05) .Calcium lactate supplementation improves performance without significant changes in the buffering system. In other words, more effort with a similar acidity to placebo could indicate the effect of calcium lactate supplementation on the performance of amateur boxing athletes.
