Context: The biomechanical analysis of sports techniques facilitates performance optimization, promotes proper technical execution, and helps to identify injury risk factors. Objective: To propose a biomechanical model of the chest technique in footvolley, indicating kinematic indicators for its evaluation. Methods: A case study with a descriptive scope was conducted through a participant with 20 years of experience in footvolley. The chest technique in footvolley was captured through video-photogrammetry using a high-speed camera (240 Hz). The analysis was carried out using the Kinovea® sports analysis software. The phases of the sports technique were determined through a previously used proposal: a) The general performance objective of the technique (GPO); b) The mechanical purposes (MP) of each phase, which refers to the main mechanical characteristic to be achieved in each phase; c) Biomechanical objectives (BO), corresponding to the kinematic (KI) and kinetic indicators (KnI) derived from the MP. Results: The technique was divided into the phases of Approach, Preparation, Impulse, and Follow-up. In each phase, the GPO of the technique and the MPs and BOs were described. Practical applications: The biomechanical proposal based on GPO, MP, and KI allows for the understanding of this sports technique, facilitating its analysis, teaching, and performance optimization.

This study shows the importance of implementing play activities for psychomotor development during early childhood. The purpose of this research was to determine the influence of the program of play activities for the perceptual-motor development in 4 and 5 year old children of the San Juan Bautista Puno-Peru Early Childhood Educational Institution. This research adopted a quantitative, experimental approach, with a pre-experimental design. A program of play activities was implemented for 10 months, basically the program developed three dimensions: sensory, motor and anatomical development.

The objective of the study is to define criteria, indicators and describe the level of preparedness of future physical education teachers. To achieve the objective of the study, the following were used: analysis, comparative analysis, retrospective analysis, synthesis, comparison, content analysis of regulations in the field of physical education and sports, a study of personal experience in teaching; systematization and generalization; abstraction and classification. The article defines the structure of the preparation of future physical education teachers for professional activity. The analysis of scientific literature and in-house experience in teaching made it possible to identify motivational, value-based, cognitive, procedural and emotional components of the readiness of future specialists for recreational activities. Their own sub-structure, interrelationship and interdependence are indicated. The criteria (motivational, cognitive, activity and personal) with the indicators and levels (low, medium, high) of the readiness of future physical education teachers for professional activities in recreational activities have been defined. It has been stated that students with a high level of readiness for professional activity are well acquainted with the use of recreational and health-improving means. They are thoroughly and consciously conversant in modern technologies of recreational activity, with a creative approach they use the acquired knowledge to solve the given tasks.

Socioeconomic information was collected using an instrument, CD4+ lymphocyte count and HIV viral load were collected from the patients' medical records. Stress level was assessed using Lipp's Stress Symptom Inventory (ISSL), and Baecke's questionnaire was used to classify physical activity level. The Man-Whitney test was used to compare the variables and the Spearman test to verify the relationship between the variables adopting p < 0.05 as the significance level. As a result, the study showed that 26.9% of the individuals are in the stress exhaustion phase, in relation to the level of physical activity, 28.2% were identified as \"active\", 23.1% as \"very active\", 23.1% as \"insufficiently active\", and 24.1% as \"sedentary\".

Inherited arrhythmogenic syndromes are a group of cardiac pathologies associated with malignant arrhythmias and sudden cardiac death, sometimes the first manifestation of the pathology. These syndromes usually manifest in the population under 35 years of age, causing arrhythmogenic episodes during sports practice. For this reason, carrying out exhaustive cardiological studies on athletes, regardless of the sport practiced, level of demand, age or gender, is essential to prevent these malignant episodes. The main entities included in this group are Long QT syndrome, Brugada syndrome, Short QT syndrome and Catecholaminergic Polymorphic Ventricular Tachycardia. A large part of the mechanisms that predispose to inherited cardiac arrhythmias continue to be one of the challenges to be resolved by biomedical research, since some of the complications in arrhythmias only occur when there is a perfect interaction between environmental and genetic factors. Advances in the study of the genome have made it possible to identify a multitude of variants in numerous genes, being these genetic alterations responsible for the predisposition to arrhythmias.

The objective of the research is to understand the meanings of the experience during the professional practices carried out by normal students of the last semesters of the Bachelor's Degree in Physical Education, during the COVID-19 pandemic of the 2020-2021 and 2021-2022 school cycles. A qualitative approach and the interpretive paradigm with a phenomenological-logical perspective were used to analyze the content of the interviews carried out, taking as a reference the principles of experience stated by Jorge Larrosa, understood as what happens to me. Four principles of experience were found to be most evident. Principle of exteriority, by recognizing the event in which the experience occurs. Principle of reflexivity, noticing the effects of experience. Beginning of passion and passage, when identifying the marks left by experiencing said event. Principle of singularity and plurality, given that, in the face of the same event, the meaning given has different scopes and interpretations. The principles reveal that most of the meanings are not focused on the teaching and learning processes, but rather are configured in interactions with authority figures, such as academic accompaniment, bureaucratic practices and assertive communication.
