Perfil antropométrico del estudiante de primer año de la carrera de educación física de la Universidad Andrés Bello generación 2015

Tesis (Profesor de Educación Física, Licenciado en Educación)Realizamos este estudio para conocer el perfil antropométrico con el que ingresan los alumnos de primer año a la carrera de Educación Física de la Universidad Andrés Bello, por lo que se evaluó a un total de 109 estudiantes, de los cuales 63 corresponden al género masculino (68,67%) y 46 al género femenino (50,14%) entre 18 y 25 años. El objetivo principal de esta investigación esta centrado en descubrir cual es el perfil con el que ingresan los estudiantes a la carrera de Educación Física, es por esto que se realizó una medición antropométrica exhaustiva a cada alumno, considerando diferentes métodos de medición. Para obtener el somatotipo utilizamos el método antropométrico descrito por Heath & Carter, realizando también la clasificación del IMC según las normas establecidas. Se espera obtener la mayor información física del sujeto y así identificar el estado en que se encuentran los estudiantes al ingresar a la carrera, y de esta manera ver si tienen un perfil antropométrico saludable, toda la información fue tabulada y analizada con diferentes fórmulas, que arrojaron resultados de IMC, porcentaje de grasa, somatotipo de los sujetos entre otros. Luego de un arduo análisis se llegaron a los resultados, esto indica que la relación de IMC, porcentaje de grasa y somatotipo no concuerdan entre sí con el resultado obtenido, y que no necesariamente los sujetos ingresan con un perfil antropométrico saludable apto para la carrera de Educación Física, se le recomienda a la Universidad realizar test físico transversal, un seguimiento de los sujetos para futuras investigaciones, y de esta forma dar pie para mejorar el nivel de ingreso de sujetos y mantener un perfil adecuado para cada estudiante de la carrera de Educación Física de la Universidad Andrés Bello

Variation in Physical-Chemical Parameters and Phenolic Compounds in Fruits of Four Calafate Clones

Calafate (Berberis microphylla G. Forst) is an evergreen shrub with blue berries that grows naturally in Patagonia, in South America. It has beneficial nutraceutical characteristics for human health. The objective of the research was to evaluate the effect of different harvest dates of calafate clones in the south-central zone of Chile on the polyphenolic content, antioxidant capacity, quality parameters and fruit yield. To meet this objective, during three consecutive years, four wild calafate clones located in the town of San Ignacio, Chile, were selected. Where a harvest period was established from 110 to 140 days after full bloom (DAFBs), each of the harvests carried out were used for the following measurements: antioxidant capacity, determination of anthocyanin content, concentration of polyphenols, phenolic compounds, soluble solids, total titratable acidity, pH, fruit yield and quality. Among the main results, it can be highlighted that clone 2 was the one that obtained the highest concentration of soluble solids, with 38.0 °Brix at 140 DAFBs. Together, it was the one that obtained the highest content of total polyphenols and concentration of anthocyanins, with 1121 g GAE kg−1 fw and 714 g cy-3-glu 100 g−1 fw, respectively

The Use of Compost Increases Bioactive Compounds and Fruit Yield in Calafate Grown in the Central South of Chile

Different concentrations of compost applied as organic fertilizer can modify productive, quality, and chemical parameters in several fruit tree species. The objective of this study was to determine the effect of increasing applications of compost on physiological, productive, and quality parameters in calafate fruit during the seasons of 2018–2019 and 2019–2020. The study was conducted on a commercial calafate orchard using a randomized complete block design with four treatments (CK: no compost application, T1: 5 Ton ha−1, T2: 10 Ton ha−1, and T3: 15 Ton ha−1), each with four repetitions. The results did not show statistical significance for stomatal conductance (Gs), quantum yield of PSII, or photosynthetic active radiation (PAR) within treatments. As for fruit yield, a statistical difference was found between the control treatment and T1, which were lower than T2 and T3 in both seasons. The trees reached a higher leaf area index with T2 in both seasons. The highest antioxidant capacity was obtained with T3 and T2 for the first and second season, respectively. Polyphenols and total anthocyanin production showed statistical significance, with a higher content at the second season with T2. It is concluded that the dose under which yield, quality, and nutraceutical content of calafate fruit are optimized is the one used in T2, 10 Ton ha−1
