The RC4 pedagogical accompaniment model is a process that allows innovative didactic and methodological strategies to strengthen the performance of teachers. The objective of this article was to propose the RC4 accompaniment model for the strengthening of teaching performance. As a methodology, a bibliographic review was carried out to identify the strategies of pedagogical accompaniment, and also through a survey of the teachers to identify through the diagnosis the perspective of the same. The results were obtained the RC4 pedagogical accompaniment model developed in four phases: awareness- diagnosis, elaboration of the accompaniment plan, verification, teaching performance. The model was based on the contribution of some authors who refer to the importance of pedagogical accompaniment to strengthen teaching performance. In conclusion, the RC4 pedagogical accompaniment model was designed to strengthen teaching performance according to the needs detected.

The objective of the study was to determine to what extent the model of active methodologies developed computational thinking in the infants of the Futuros Navegantes institution, Guayaquil 2021. Applied research was used with the quasi-experimental design, considering two groups of infants from the initial level 2, the first called control group with 30 children and the second 31 students for the experimental group. Applying an observation guide with 20 items, with a polytomous response option. The descriptive results revealed in the pre-test of the experimental group that the infants were at the beginning level with 96.77%, differing in the post-test with 61.29% in process and 19.35% reached achievement. Admitting the affirmative hypothesis and rejecting the null hypothesis, concluding that the active methodologies model made a significant difference in computational thinking, as well as in logical thinking, problem solving and creative thinking.

Introduction: Soccer is a complex acyclic discipline, which is particularly demanding of very high physical aptitudes. Aim: To determine the anthropometric characteristics, body composition, and somatotype to unveil the morphological profile of professional Ecuadoran soccer players, and compare them according to the game positions. Materials and methods: An observational-descriptive study was conducted. A number of 73 Ecuadoran professional soccer players were evaluated, including seven goalkeepers, 25 defenders, 29 wingers, and 12 attackers. The international ISAK protocol was performed for measurements, with optimally calibrated equipment. An ANOVA was performed to describe the information, and a Student-T test was conducted to verify the significant differences (p<0.05) by game position. Results: Significant differences (p<0.05) were observed among the different game positions, especially between the goalkeepers and the other players. Compared to the international players, the Ecuadorans differed in terms of basic measurements and muscle mass. The other variables were similar. Conclusions: The anthropometric characteristics, body composition, and somatotype of professional Ecuadoran soccer players by position and overall average were determined. There were significant differences among the variables studied by game position. The Ecuadoran soccer players have different basic metrics from the group of international players, with lower muscle mass. Concerning fat, sum of 6 skinfold thickness, muscle-bone index, and somatotype, the similarities were remarkable.

Introduction: Spinal cord injury could be considered as any alteration of the spinal cord that can lead to changes in movement, sensitivity, or autonomous functions below the level of the injury. Among the main limitations are gait loss, which, in most cases constitutes the major recovery priority for patients. Aim: To evaluate the progress of patients with spinal cord injury at the International Center for Neurological Restoration. Materials and methods: From a total of 60 patients, a sample of 30 patients was selected at random for a study that took place between 2017 and 2019. The individuals met the inclusion criteria, and performed gait actions measured with the gait scale for spinal cord injury, version II. The data collected were processed using SPSS 28. Results: The results showed statistically significant changes in the sample analyzed by sex, region injured, gait rehabilitation time, and overall status. Conclusions: The evaluation of gait showed that the related actions taken at the International Center for Neurological Restoration were effective, and led to significant changes in the patients' gait abilities.

Introduction: Judo is a martial art whose practice is done under an atmosphere of respect, discipline, and strictness; hence every physical capacity must be enhanced through several different methods.Aim: To design a program for judo teaching and learning of the basic techniques by the students of the Pedagogic Degree of Physical Activity and Sports in the University of Guayaquil.Methods: An experimental study was conducted in the form of pedagogic pre-experiment, which showed significant changes in the performance of basic judo techniques. A total of 26 subjects in the sixth term of the program were included, all belonging to the University of Guayaquil. The methods used were measurements and the results of three basic judo technique tests, such as Tachi waza, Osae-Komi-Waza, and Kwansetsu-Waza. Results: The main results consisted of a program with the following structure: introduction, content rationale, contribution to the graduate profile, theme or analysis units, and learning assessment, which were closely linked to the system and contents. Conclusions: The feasibility of the judo program was confirmed in the Pedagogic Degree of Physical Activity, which brought about substantial improvements and significant contrasts in the implementation of the basic techniques during the post-test, with increases over 50 % in the results of the tests performed.

Introduction: Biomechanics is one of the most demanding activities, when human movements are studied in sports, as the proper scenario to improve research skills with the comprehensive preparation of university students and society. In Cuba, research is done to implement changes in the existence of inequalities between men and women, as several studies deal with the gender approach in the sports context. Aim: To study the flexibility of junior female karate athletes in Cienfuegos, with a gender approach, to enhance student research skills as part of the scientific group of students at the Bachelor Degree of Physical Culture and Sports. Methods: This research study was conducted with a qualitative approach, using theoretical methods like the historical-logical and documentary analysis; the empirical method used was structured interview of female athletes engaged in combat sports. Results: This work showed an improvement in research skills. The students played a key role in the enhancement of kicking techniques, and greater flexibility of junior karate athletes in the study. Conclusions: The biomechanical analysis conducted by the members of the scientific group of students showed enhanced research skills in Sports Biomechanics.

Introduction: The practice of basic motor skills during infant learning helps articulate and enhance the basic motion abilities through Physical Education. These actions are then conceptualized and strengthened into more complex motor skills, such as movements, jumps, balances, throwing, and catching. Aim: to conduct an analysis of didactic strategies used in Physical Education to tackle basic motor skills. Materials and methods: the main method used was systematic review, under the PRISM method design, and the practical guide for systematic reviews regardless of meta-analysis. Results: The most outstanding results were observed in 4 studies, using a version of theoretical and empirical methods suggested by other authors. Conclusions: Physical Education is the main axis to build infant motor skills, used as the denominator of motor and cognitive development. It lies within the body concepts in favor of anatomical gesture movement during their life cycle.
