The influence of physical education at school on the attention of students aged 15-16 years / El impacto de la educación física en la escuela en la atención de los estudiantes de 15 a 16 años / O impacto da educação física na escola na atenção de estudantes de 15 a 16 anos

ABSTRACT Objectives: the influence of physical activity in physical education lessons on the attention indicators of schoolchildren. Material and Methods: 141 students, aged 15-16, who studied in the 9th grade, took part in the experiment. The main research method was the "Trondyke Test", which determines the level of attention development of students. The test was used before and after the physical education lesson 1 time per month for 5 months. Results: students who did not engage in physical education in the lesson were not able to significantly improve their performance in the test, which indicates a possible adaptation to the test after its first performance before the lesson. Students who were engaged in physical exercises could significantly increase the test results. Conclusion: the results obtained determine the effectiveness of the influence of a physical education lesson at school on the indicators of students attention. This study will serve as an additional motivation for students to engage in physical culture, since the impact of physical exercises has a positive effect not only on the development of physical qualities, but also on the attention of schoolchildren. Level of Evidence III; Retrospective Comparative Study.

Flash Therapy for Cancer: A Potentially New Radiotherapy Methodology.

In traditional treatment modalities and standard clinical practices, FLASH radiotherapy (FL-RT) administers radiation therapy at an exceptionally high dosage rate. When compared to standard dose rate radiation therapy, numerous preclinical investigations have demonstrated that FL-RT provides similar benefits in conserving normal tissue while maintaining equal antitumor efficacy, a phenomenon possible due to the 'FLASH effect' (FE) of FL-RT. The methodologies involve proton radiotherapy, intensity-modulated radiation treatment, and managing high-throughput damage by radiation to solid tissues. Recent results from animal studies indicate that FL-RT can reduce radiation-induced tissue damage, significantly enhancing anticancer potency. Focusing on the potential benefits of FL proton beam treatment in the years to come, this review details the FL-RT research that has been done so far and the existing theories illuminating the FL effects. This subject remains of interest, with many issues still needing to be answered. We offer a brief review to emphasize a few of the key efforts and difficulties in moving FL radiation research forward. The existing research state of FL-RT, its affecting variables, and its different specific impacts are presented in this current review. Key topics discussed include the biochemical mechanism during FL therapy, beam sources for FL therapy, the FL effect on immunity, clinical and preclinical studies on the protective effect of FL therapy, and parameters for effective FL therapy.

The effectiveness of one "physical education minute" during lessons to develop concentration in 8- to 10-year-old schoolchildren.

The demands of the school day, which includes multiple lessons, require sustained attention from students; this can be challenging, especially for young children. Concentration of attention is a critical cognitive function that impacts learning. This study involved 129 healthy schoolchildren aged 8-10 years (spanning grades 2 and 3) from a regular secondary school in Kirov, Russian Federation. A "physical education minute" (PEM), consisting of various physical exercises, was introduced during the middle of a regular lesson for the experimental group (EG), while the control group (CG) continued with their regular studies. Concentration and attention were assessed before and after the PEM using the Bourdon test. The Bourdon test results indicated a significant decrease in concentration during the lesson for the CG (p < 0.001), while the EG exhibited significant improvement in concentration after the PEM (p < 0.001). The effect size was large, demonstrating a substantial impact of this break for physical activity on concentration. It can be concluded that implementing a set of exercises in the form of a PEM in the middle of a lesson significantly improves concentration among students aged 8-10. This study underscores the effectiveness of integrating short breaks for physical activity into the daily classroom routine, ultimately benefiting students' attention, learning, and overall educational experience. Further research could explore additional factors affecting concentration and the long-term effects of the PEM on cognitive development.

Genetic Testing for Successful Cancer Treatment.

Cancer genetic testing is a revolutionary medical approach that involves the assessment of genetic markers in asymptomatic individuals to predict their future susceptibility to cancer. This paradigm shift in early detection and intervention has the potential to profoundly alter our strategies for cancer prevention and treatment. One pivotal area where genetic testing can have a significant impact is among families with a hereditary predisposition to cancer. Recent research has seen a surge in the exploration of how individuals perceive their cancer risk within the realm of cancer genetics. This proactive approach to genetic testing allows healthcare professionals to identify family members who may carry the same cancer-related genetic mutations, empowering them to make informed decisions regarding their healthcare and cancer risk management. Genetic testing for cancer-related disorders has significantly improved in accuracy and affordability, potentially revolutionizing monitoring and treatment methods. The expanding knowledge of genetic mutations associated with cancer susceptibility has driven significant progress in cancer therapy. Identifying numerous major cancer susceptibility genes has propelled predictive genetic testing, providing individuals with valuable insights into their genetic predisposition to cancer. While perceived risk plays a vital role in genetic counseling, it is equally essential to offer comprehensive information about the advantages and potential risks associated with genetic testing. Ensuring that individuals have a clear understanding of the benefits and potential drawbacks of genetic testing is imperative for making informed healthcare decisions. In our comprehensive review, researchers explored several critical aspects of genetic testing in the context of cancer, including awareness and knowledge, the communication of cancer genetic risk, genetic testing for inherited cancer syndromes, and the challenges and limitations linked to genetic testing. Through this examination, we aim to illuminate the transformative potential of genetic testing in cancer prevention and treatment.

The Influence of Burpee on Endurance and Short-Term Memory of Adolescents.

Aim-The purpose of this study was to assess the effect of the Burpee exercise on the endurance and short-term memory of adolescents aged 15-16 years. Methods-The experiment was performed in a coeducational school in Kirov (Russia). The four-month study involved 52 adolescents of both genders. During the study period, 30 physical education lessons were held in each class. Adolescents from the control group were involved in a typical program (also aimed at improving endurance), and adolescents from the experimental group additionally performed the Burpee exercise. Endurance in adolescents was assessed by means of an "all-out" Running 2000 m test, and short-term memory was assessed by means of the Jacobs test (tests were performed before and after the programs). Results-An analysis of variance revealed an interaction effect (F = 28.733, ηp2 = 0.578 and p < 0.001, and F = 104.353, ηp2 = 0.676 and p < 0.001 for the Running 2000 m test and the Jacobs test, respectively). The control group improved by 1.9% (p > 0.05) in the Running 2000 m and by 5.5% (p > 0.05) in the Jacobs test. In the experimental group, both improved significantly by 8.6% (p < 0.05) in the Running 2000 m test and by 26.0% (p < 0.05) in the Jacobs test. Conclusion-The Burpee exercise could be included in physical education classes to improve endurance and short-term memory in 15-16-year-old.

The influence of Burpee on the stability of attention of schoolchildren

Abstract Aim: To determine the influence of the «Burpee¼ exercise on the indicators of endurance and stability of attention in children aged 15-16. Methods: the pedagogical experiment was carried out based on a comprehensive school, in the city of Kirov, Russia. The study involved children 15-16 years old in the amount of 52 people. Children from the experimental group additionally performed the "Burpee" exercise. Endurance in children was determined by the test "2000 m", and the stability of attention was determined by the test "Bourdon test". The study used Excel and BioStat to determine Student's t-test. Results: After the pedagogical experiment, the indicators in the control group in the "2000 m" test improved by 1.9% (p > 0.05), and in the "Bourdon test" by 5.9% (p > 0.05). In the experimental group, the performance improved significantly in the "2000 m" test by 9% (p < 0.05) and in the "Bourdon test" by 20% (p < 0.05). Conclusion: if 15-16-year-old schoolchildren perform the "Burpee" exercise in physical education classes, then the indicators of endurance and stability of attention will improve significantly.
