The study showed that both experimental groups presented favorable results for BMD, strength, FA and QoL. However, the RT3 showed the best results compared to other groups after 13 months of intervention.

Objetivo: evaluar el efecto de un programa de educación física adaptado en escolares con discapacidad auditiva sobre el cociente motor. Método: el diseño del estudio fue cuasiexperimental, con muestreo por conveniencia, participando treinta y ocho niños con una edad promedio de 7.4±0.9 años, diagnosticados con debilidad o pérdida auditiva, de dos escuelas de la ciudad de Mexicali, Baja California. México. Los participantes fueron divididos aleatoriamente en un grupo experimental (n=23) y otro control (n=15), a los cuales se les evaluó el cociente motor mediante el test de coordinación corporal para niños KTK (Körperkoordinationstest für Kinder de Kiphard y Schiling), por sus siglas en alemán, mediante las pruebas: desplazamientos en equilibrio de espaldas, saltos monopódales, saltos laterales y transposición sobre plataforma. El programa se realizó durante 4 meses, 5 veces por semana, con una duración de 50 minutos por sesión, comunicándose con los alumnos mediante el lenguaje de señas mexicano y realizando una serie de tareas que enfatizaran la coordinación motora. Resultados: al comparar los resultados entre grupos de la variable cociente motor, con el análisis de varianza (ANOVA) mixtas 2 x 2 se observó una interacción doblemente significativa entre los grupos y las mediciones (p = 0.01), los porcentajes de cambio (Δ %) fueron 26 % del grupo experimental y 6.5 %. del grupo control (Δ %). Conclusión: se establece que la aplicación de un programa de educación física adaptado durante cuatro meses, mejora la coordinación motora en niños con discapacidad auditiva.

The purpose of this research was to determine the somatotype profile and body composition of team members of Soles de Mexicali from the Mexican professional basketball league season 2012. A descriptive cross-sectional study in which 10 members of that team are evaluated to determine the somatotype and body composition, they were assessed with anthropometric variables in accordance with ISAK (International Society for the Advancement of Kinanthropometry was performed) the equipment used was the Tom Kit Rosscraft Inc. The somatotype and body composition were determined through measurements of body weight (cm), height (cm), eight skinfolds (mm) triceps, sub scapular, biceps, iliac crest, supra spinal, abdominal, front thigh, medial calf, eleven circumferences (cm) arm relaxed, flexed arm, forearm, wrist, chest, low waist, high hip, thigh, buttock 1 cm, mid-thigh, calf and ankle, and two bone diameters (cm) humeral and femur. The data were processed or through Life Size Software Sports Scientific Reynolds. The following data are reported in the first reference of the Mexican league players assessed a somatotype 2.94-6.35-2.06 average and the percentage of body fat of the subjects tested was 14.46%. The values found in this study indicate a significant an optimal state of body fat percentage and somatotype similar when is compared with existing studies on national teams and international basketball.

SUMMARY:Physical function declines in efficiency with advancing age, contributing to disability. Furthermore, metabolic syndrome is a common illness in elderly populations, somatotayping is a technique for description of the physique and can establish a relation with performance and pathology. The aim of this work was to compare the agility, dynamic balance in elderly women with endomorphic mesomorph somatotype with presence or absence of metabolic syndrome. A sample of 18 volunteers was obtained (age 66.5±4.7 years old), all were elderly sedentary women. They were assessed whit anthropometric variables in accordance with ISAK protocol in order to determine Heath & Carter somatotype; presence of metabolic syndrome they were evaluated according with the NCEP ATP-III, the agility and dynamic balance was assessed with the functional test Time Up and Go (TUGT). Mean of somatotype in subjects with absence or presence of metabolic syndrome was 6.2-7.9-0.2 and 6.5-8.7-0.1 respectively; Shapiro-Wilk test checked the normality of the distribution in the functional test Time Up and Go, in the group with absence or presence of metabolic syndrome, based on its normality distribution for the intergroup comparison, the Student t test was applied, the significance level, utilized was 95% (P≤ , 0.05) for the sample assessed without metabolic syndrome, the execution time of the functional test TUGT was better in spite of the same somatotype intergroup. The pathological components of metabolic syndrome can be related whit dysfunctional mobility in elderly women.

Background: Our objective was to establish a sustainable educational partnership and clinical exchange between the trauma services at Vancouver General Hospital (VGH) and the Mexican Red Cross hospital in Mexico City (Hospital Central de la Cruz Roja [HCCR] Polanco). Methods: In 2017, a general surgery resident in postgraduate year 4 travelled from VGH to HCCR Polanco for the initial exchange, followed by a trauma fellow. The surgical case volumes in a month at VGH and a month at HCCR Polanco were compared. At the end of the exchange, a 36-item Likert style questionnaire was administered to the Mexican surgeons and residents who interacted with the Canadian resident and fellow during the exchange. Results: The most commonly performed procedures on the VGH acute care surgery service were laparoscopic cholecystectomy (35%) and laparoscopic appendectomy (17%). The most commonly performed procedures on the VGH trauma service were chest tube insertions (24%) and tracheostomies (24%). The most commonly performed procedures at HCCR Polanco were surgery for penetrating abdominal trauma (19%) and extremity trauma (13%). The survey results indicated that the costs of travel and accommodation were obstacles to future exchanges. All survey respondents wanted to continue collaborating with Canadians on clinical and research endeavours, felt that hosting Canadian residents was a valuable experience and felt that visiting VGH would also be valuable. Conclusion: Canadian surgical trainees gained valuable exposure to operative trauma during the exchange. The mix of operations performed at VGH and HCCR Polanco was vastly different; therefore, the exchange broadened the trainees' surgical experience. There was a unanimously positive response to the exchange among the Mexican survey respondents. This exchange is part of a long-term collaboration between our surgical centres. Contexte : Notre objectif était d'établir un partenariat pédagogique et un échange clinique durables entre les services de traumatologie de l'Hôpital général de Vancouver

Objective: To compare the moderate-to-vigorous physical activity of physical education classes taught by teachers and their students during recess. Method: In order to determine the physical activity intensity the system for observing fitness instruction time (SOFIT) was used, a descriptive cross-sectional comparative methodological design was used, 63 physical education classes were evaluated selecting randomly four students from each class (2 men and 2 women), the same procedure was followed to evaluate the same 4 students during the 30 minutes of recess. Results: The equality of variance was calculated using the Student t test for independent samples resulting a P-value=.001 α≤ less than 0.05, with a percentage time of moderate-to-vigorous physical activity in physical education classes taught by teachers of 41%±17.7 and performed by students during recess of 50%±10.3, the percentage of difference (Δ%) was of 18% between the variables. Conclusion: The intensity of physical activity during recess was higher without teacher instruction in relation to physical education classes evaluated, due is important a feedback for the teachers in strategies for involving the students in moderate to vigorous physical activity as established by the World Health Organization. Resumen. Objetivo: Comparar la actividad física moderada a vigorosa de clases de educación física impartidas por profesores y la intensidad de la actividad física de sus estudiantes durante el recreo. Método: Se utilizó como instrumento de evaluación el sistema para observar el tiempo de instrucción de actividad física (SOFIT), el diseño metodológico fue transversal descriptivo comparativo, evaluando 63 clases de educación física seleccionado al azar cuatro estudiantes de cada clase (2 hombres y 2 mujeres), el mismo procedimiento se siguió, evaluando a los mismos 4 estudiantes durante los 30 minutos del recreo. Resultados: La igualdad de la varianza se calculó mediante la prueba t Student para muestras independientes resultando una P-Valor=.001 menor a α≤ 0.05, el porcentaje de tiempo de actividad física moderada a vigorosa en las clases de educación física impartidas por profesores fue de 41%±17.7 y la realizada por los estudiantes durante el recreo resulto en 50%±10.3 y un porcentaje de diferencia (Δ%) de 18%. Conclusión: La intensidad de actividad física durante el recreo fue mayor sin instrucción docente en relación a las clases de educación física evaluadas, por lo anterior es importante retroalimentar de manera constructiva la manera de impartir la clase de los profesores mediante capacitación con estrategias didácticas para involucrar al alumno en actividad física moderada a vigorosa como lo establece la Organización Mundial de la Salud.

SUMMARY:The aim of this study was to evaluate the effect of a hydrogymnastics training program on Body fat and Fatfree mass in elderly women. The subjects were randomly divided in experimental groups that participated in the hydrogymnastics training program and control group that was not involved in the training and remained sedentary. They were assessed with anthropometric variables in accordance with ISAK protocol in order to determine Body fat (Kg), Fat-free mass (Kg), the training protocol consisted of hydrogymnastics sessions 5 times per week during 12 weeks of intervention, executed in a pool of 1.3 meters divided into three phases: a 10 minute warm-up, 30 minutes of aerobic exercise at 50-60% of maximum heart rate (monitored by heart rate monitor) and a 10 minute cool down. As a statistical method to compare the results between groups of variables pre and post training, the analysis of variance (ANOVA) mixed 2 X 2 (group X measurement) test was done using SPSS version 17. The findings showed no significant increase in measurements of muscle body composition component; no significant changes in fatty tissue of body composition were observed. These results were similar and congruent with studies carried out previously in elderly adults, where physical exercise programs, during which the subjects are active for less than 30 minutes, three times a week, lead to small or no changes in body mass and body composition.

Abstract. Objective: To compare the levels of physical activity in university athletes before and during the confinement due to pandemic associated with COVID-19. Method: thirty-two university student athletes enrolled in the Sports Faculty of the Autonomous University of Baja California. The average age of the participating subjects was 21.4 ± 3.6 years (17 men and 15 women). To assess the physical activity level, the international physical activity questionnaire (IPAQ) was used; measurements were carried out before and during confinement by COVID-19. Results: To determine equality of variance, the Student's t-test for independent samples was applied, with less physical activity (-33.6 Δ%), MET-minutes/week during confinement by COVID-19 (p=.005). Conclusions: Despite decreasing physical activity, the university athlete performed physical activity at home during confinement by COVID-19, harmonizing the time in the learning processes in their future profession.  Resumen.
