摘要: Conocer la relacion entre capacidad aerobica, fuerza muscular y factores de riesgo enfermedad cardiovascular en ninos adolescentes es interes cientifico sanitario. Ademas, para poder interpretar una manera mas precisa estas asociaciones necesario disponer metodologia sencilla fiable. Esto puede ayudar a crear estrategias prevencion primaria desde las edades tempranas. El objetivo general esta memoria Tesis Doctoral estudiar condicion fisica (especialmente aerobica muscular) jovenes, asi como desarrollar nuevos metodos estimacion adolescentes. Un total 873 9 10 anos 971 12 19 conforman poblaciones que han participado los tres estudios cohortes incluidos presente Tesis: estudio AVENA (Alimentacion Valoracion del Estado Nutricional Adolescentes Espanoles), el EYHS (European Youth Heart Study), HELENA (Healthy Lifestyle in Europe by Nutrition Adolescence). Los principales resultados sugieren que: a) La se relaciona con parametros salud b) asocia inversamente tradicionales anos. c) un factor novel tal homocisteina ninas adolescentes, esto tras ajustar por distintas variables confusion incluido genotipo MTHFR 677C>T. d) proteinas inflamacion aguda tales proteina C reactiva e) Se ha desarrollado validado nueva formula consumo maximo oxigeno partir resultado obtenido test ida vuelta 20 metros, sexo, edad, peso talla adolescente. f) Hay tamano agarre optimo deberia ser ajustado dinamometro cuando evalue prension manual muestran particular constituyen importante marcador al igual ya habia mostrado adultos. Estos datos confirman necesidad incluir este tipo mediciones sistemas educativos publica. desarrollo evaluacion aplicados epidemiologicos ayudara mejorar calidad rigor mismos. Abstract For public health strategies and preventive purposes, it is of interest to understand the associations between cardiorespiratory fitness, muscle strength disease risk factors children adolescents. Development new more accurate methodology assess fitness may help better elucidate links from on early ages. The overall objective this thesis was examine association physical (focused strength) both traditional young populations, develop methods estimate adolescents.A (aged years), adolescents years) three different studies were involved present work: study Adolescence) Study. main outcomes were: Physical associated myriad parameters people. Cardiorespiratory inversely with children. factor, such as homocysteine levels female after controlling for potential confounders including 677C>T genotype. Muscle inflammatory proteins, reactive protein, A equation maximum oxygen consumption 20m shuttle run performance (last half stage completed), sex, age, weight height has been developed cross-validated. There anoptimal grip span which dynamometer should be adjusted when measuring handgrip results show that especially an important marker also people, shown adults. Health information systems include monitoring among individuals. ofefficient large-scale collection data improve quality accuracy outcome.
