ABSTRACT
BACKGROUND: COVID-19 confinement measures in the population affected the quality of life and sleep. AIMS: To determine if confinement is associated with a lower quality of life and sleep. SUBJECTS AND METHODS: A self-reported survey including questions about type of confinement, time spent in front of a screen, the international physical activity questionnaire (IPAQ), the Sleep Self Report questionnaire and the SF-36 quality of life survey, was answered by 621 Chilean university students. RESULTS: Confined and not confined respondents spent a great amount of time in front of a screen, in sedentary activities and sleeping > 8 or < 6 hours per day. Those who were in confinement reported having a poorer quality of sleep and quality of life compared to those who were not in confinement. Those who required mandatory confinement for suspected COVID-19 had the worst quality of sleep and quality of life. CONCLUSIONS: University students had sedentary lifestyles regardless of the type of confinement. Those who were in confinement, especially for suspected COVID-19 infection, had the worst quality of sleep and quality of life.

Body mass index (BMI) is widely used in the world, despite caveats concerning its interpretation in relation to gender, age, and race. BMI reading is normally standardized, potentially producing error in the results and classification of nutritional status. Body composition provides more relevant information than BMI: fat mass and lean mass are the main indices. This paper reviews existing equations and proposes the simplest ones and those with the lowest estimation error to replace or complement BMI and improve interpretation of nutritional status and physical activity.

The body mass index (BMI) provides one of the indices used to determine the nutritional status of the population worldwide, where despite the existence of clear recommendations for interpretation and defi ned as gender, age, race, etc. usually their classifi cation, independent of the variables is standardized, increasing the error in the result and classifi cation of nutritional status. The use of body composition through anthropometry, delivers more information than BMI, being fat mass and muscle mass leading useful results. This article presents a review of existing and proposed those equations simpler and less error estimate to be used as a tool to replace or supplement to BMI, promoting a better understanding and interpretation of nutritional status and level of physical activity in children and adolescents (AU)

El desarrollo de la resistencia cardiorrespiratoria en niños, adolescentes y jóvenes se asocia a la disminución de la prevalencia de enfermedades cardiovasculares en niños y adolescentes. La prueba de course navette o carrera de 20 metros es una prueba de aptitud cardiorrespiratoria máxima y progresiva, que mide indirectamente el consumo máximo de oxigeno. Niveles altos de capacidad aeróbica durante la niñez y la adolescencia están asociados con una salud cardiovascular actual y futura más saludable. Según la encuesta nacional de salud en Chile (2009-2010) el 17,7 por ciento de la población chilena mayor de 15 años y más, presenta un riesgo cardiovascular alto o muy alto. La población chilena presenta: un elevado nivel de morbilidad por enfermedades crónicas no transmisibles y de sus factores de riesgo. Utilizar una prueba máxima y progresiva en adolescentes, como es la prueba de course naveta, puede genera un aumento del riesgo de presentar un evento cardiovascular al evaluar el consumo máximo de oxigeno en nuestra población.
The development of cardiorespiratory endurance in children and young people is associated with decreased prevalence of cardiovascular disease in children and adolescents. The test of "course navette" or 20 meter race is a test of high cardiorespiratory fitness and progressive, which indirectly measures the maximum oxygen consumption. High levels of aerobic fitness during childhood and adolescence are associated with a current cardiovascular health and healthier future. According to the health survey in Chile, 17.7 percent of the Chilean population 15 years and over, has a high or very high cardiovascular risk. The Chilean population has: a high level of morbidity from chronic diseases and their risk factors of disease. Use a high and progressive test in adolescents, such as "proof of course navetta" can generate an increased risk of cardiovascular events in assessing the maximum oxygen consumption in our population.

OBJECTIVE: the aim of the present study was to determine the effect of training and the consequences of detraining, comparing an aerobic training (AT) protocol with a resistance training (RT) in people with type-II Diabetes Mellitus (DMII). METHODS: a total of 30 individuals participated in the study, with ages ranging from 45 to 50 years, all diagnosed with DMII and not currently receiving pharmacological treatment. Participants were divided at random into an AT group (65% of their maximum aerobic capacity) and a RT group (1 x 2 x 3 protocol at 65% of 1RM). Measurements were taken of weight, body mass index, total cholesterol, HDL-C, LDL-C, triglycerides, glycaemia in a fasted state and glycosylated haemoglobin (HbA1C) at the beginning and at the end of the 6-week training period, and after a further 6 weeks of detraining. RESULTS: the results show that both physical training protocols are capable of inducing significant modifications in lipid profile, glycaemia in a fasted state and levels of HbA1C; however, after stopping the training programme only the RT group maintained the benefits of the reduction in LDL-C, HbA1C and the increase in HDL-C. CONCLUSIONS: resistance exercise in individuals with DMII has an important influence on health and their effects could be maintained even if the training program is interrupted short-term.
Objetivo: el propósito del presente estudio fue determinar el efecto del entrenamiento y las consecuencias del desentrenamiento comparando un protocolo de entrenamiento aeróbico (E-Aer) y otro de sobrecarga (E-Sob). Métodos: participaron 30 personas entre 45-50 años de edad con diagnóstico de diabetes mellitus tipo II (DMII) sin tratamiento farmacológico. Fueron aleatorizados a un grupo de E-Aer (65% de su esfuerzo máximo) o a un grupo de E-Sob (protocolo 1 x 2 x 3 al 65% de 1RM). Se midió el peso, el índice de masa corporal, el colesterol total, HDL-C, LDL-C, triglicéridos, glucemia en ayuno y la hemoglobina glucosilada (HbA1C) al inicio, al finalizar las seis semanas de entrenamiento y tras seis semanas de desentrenamiento. Resultados: los resultados indican que ambos protocolos de entrenamiento físico son capaces de inducir modificaciones significativas en el perfil lipídico, la glicemia en ayuno y los niveles de HbA1C; sin embargo, solo el grupo E-Sob demostró mantener los beneficios logrados tras haber interrumpido el programa de entrenamiento en la reducción del LDL-C, HbA1C y en el incremento del HDL-C. Conclusiones: el ejercicio de sobrecarga en personas con DMII influye de manera importante en la salud, efecto que podría mantenerse incluso si se llega a interrumpir a corto plazo el programa de entrenamiento.

Body composition is a non-invasive method, which gives us information about the distribution of tissues in the body structure, it is also an indicator of the risk of mortality in patients with chronic obstructive pulmonary disease. The heart rate variability is a technique that gives us information of autonomic physiological condition, being recognized as an indicator which is decreased in a number of diseases. The purpose of this study was to assess body composition and heart rate variability. The methodology used is that of Debora Kerr (1988) endorsed by the International Society for advances in Cineantropometría for body composition and heart rate variability of the guidelines described by the American Heart Association (1996). Roscraff equipment, caliper Slimguide and watch Polar RS 800CX was used. , BMI 26.7 ± 3.9 kg / m²; Muscle Mass 26.1 ± 6.3 kg ; Bone Mass 1.3 kg ± 8.1 76 ± 9.9 years Age : 14 candidates for pulmonary rehabilitation patients were evaluated , Adipose mass 16.4 ± 3.6 kg ; FEV1 54 ± 14%. Increased waist circumference and waist hip ratio was associated with a lower overall heart rate variability. The bone component was positively related to the variability of heart rate and patients with higher forced expiratory volume in one second had lower high frequency component in heart rate variability. In these patients, the heart rate variability is reduced globally and is associated with cardiovascular risk parameters.

La variabilidad del ritmo cardiaco es una técnica que nos entrega información de la condición fisiológica autonómica, siendo reconocida como un indicador que se encuentra disminuido en una serie de enfermedades. El propósito de este estudio fue evaluar la composición corporal y la Variabilidad del ritmo cardiaco. La metodología utilizada es la de Debora Kerr (1988) avalada por Sociedad Internacional para avances en Cineantropometría para composición corporal y para Variabilidad del ritmo cardiaco los lineamientos descritos por la American Heart Association (1996). Se empleó equipamiento Roscraff, caliper Slimguide y reloj Polar RS 800CX. Se evaluaron 14 pacientes candidatos a rehabilitación respiratoria: Edad 76 ± 9,9 años; IMC 26,7 ± 3,9 kg/m²; Masa Muscular 26,1 ± 6,3 kg; Masa Ósea 8,1 ± 1,3 kg; Masa Adiposa 16,4 ± 3,6 kg; VEF1 54 ± 14 %. Un mayor perímetro de cintura e índice Cintura Cadera se asoció a una menor Variabilidad del ritmo cardiaca global. El componente óseo se relacionó positivamente con la Variabilidad del ritmo cardiaco y los pacientes con un mayor Volumen espiratorio forzado en el primer segundo presentaron un menor componente de alta frecuencia en la Variabilidad del ritmo cardiaco. En estos pacientes, la Variabilidad del ritmo cardiaco en forma global se encuentra reducida y se asocia con parámetros de riesgo cardiovascular.

En nuestro país y en el mundo se han realizado una serie de investigaciones en el área de la morfoestructura humana, pero pocos trabajos que describan el perfil antropométrico de personas jóvenes saludables. Se evaluaron a 100 hombres y 79 mujeres de entre 20 y 29 años de edad, sin factores de riesgo a la salud. Se evaluó de acuerdo a un protocolo de ISAK con variables que permite estimar la composición corporal y el somatotipo de los individuos. De esta manera se presentan las tablas de resultados como una forma de usarlas de referencia. Nuestro grupo de referencia evaluado (CHIREF) con sus resultados de composición corporal, somatotipo e índices corporales, aporta una nueva fuente de información de la V Región y actualizada para Chile, la cual favorecerá las comparaciones para distintos grupos de edades, condiciones de salud, deportes y etnias, considerando la necesidad de aumentar el grupo etario y la cantidad de variables antropométricas para ampliar el universo de comparación y mejorar la referencia comparativa.
In our country and worldwide, extensive research has been carried out in the human morphostructure, however there is limited work that describes the anthropometric profile of young healthy individuals. One hundred men and seventy nine women were evaluated between 20 and 29 years of age without health risk factors. The evaluation was in accordance with ISAK protocol and variables in body composition estimate and somatotype. Reference tables of the results are also included. Reference group (CHIREF) with the results of body composition, somatotype and other corporal indexes contribute as a source of information from Chile, which will aid in comparison studies for different age groups, health conditions, sports and ethnicity, considering the need to increase the age group and the amount of anthropometric variables so as to expand the range of comparison and improve comparative referentes.
