          Abstract

          Introducción: La acelerometría, se muestra como una de las técnicas más fiables, en el registro y almacenamiento de la cantidad y el nivel de actividad física, realizada por cada persona y en un periodo de tiempo determinado. Objetivo: Esta revisión tiene como objetivo describir y analizar los principales artículos que utilizan este método para valorar la actividad física. Método: Los artículos seleccionados para ser incluidos en esta revisión se identificaron a través de los siguientes motores de búsqueda especializados: SCOPUS, PUBMED, GOOGLE SCHOLAR; con un total de 56 artículos. La validez de los artículos estuvo dada por el grado de evidencias demostrado, por las recomendaciones que describen y por la aplicabilidad a nuestro contexto. Esta revisión ha considerado los estudios que evalúan la actividad física a través de acelerómetros. Resultados: Los resultados demuestran que este método se puede utilizar en edades comprendidas entre 3 y 90 años. También se puede utilizar en personas con sobrepeso/obesidad, con lesiones articulares, niños con síndrome de Down, autistas, así como personas con problemas psicológicos. Los estudios en mujeres embarazadas muestran datos fiables. Conclusión: La literatura analizada establece la acelerometría como un método eficaz para valorar la actividad física.

          Introduction: The accelerometer is shown as one of the most accurate techniques in recording and saving the amount and level of physical activity, by each person in a given period of time. Aims: This review aims to describe and analyze the main items that use this method to assess physical activity. Methods: The review articles were identified through the following specialized Internet browser: SCOPUS, PUBMED, GOOGLE SCHOLAR, those were selected for inclusion with a total of 56 items. The validity of the articles was given by the degree of evidence demonstrated by describing the recommendations and the applicability to our context. This review has considered studies evaluating physical activity through accelerometers. Results: The results show that this method can be used in ages 3 to 90 years. It can also be used in subjects with overweight/obesity, articulation injuries, Down syndrome (just children), autism and people with psychological problems. Studies in pregnant women show satisfactory results. Conclusion: The literature reviewed provides the accelerometer as a reliable and effective method to assess physical activity.

          Compendium of physical activities: an update of activity codes and MET intensities.

          We provide an updated version of the Compendium of Physical Activities, a coding scheme that classifies specific physical activity (PA) by rate of energy expenditure. It was developed to enhance the comparability of results across studies using self-reports of PA. The Compendium coding scheme links a five-digit code that describes physical activities by major headings (e.g., occupation, transportation, etc.) and specific activities within each major heading with its intensity, defined as the ratio of work metabolic rate to a standard resting metabolic rate (MET). Energy expenditure in MET-minutes, MET-hours, kcal, or kcal per kilogram body weight can be estimated for specific activities by type or MET intensity. Additions to the Compendium were obtained from studies describing daily PA patterns of adults and studies measuring the energy cost of specific physical activities in field settings. The updated version includes two new major headings of volunteer and religious activities, extends the number of specific activities from 477 to 605, and provides updated MET intensity levels for selected activities.

            Physical activity of Canadian children and youth: accelerometer results from the 2007 to 2009 Canadian Health Measures Survey.

            Physical activity is an important determinant of health and fitness. This study provides contemporary estimates of the physical activity levels of Canadians aged 6 to 19 years. Data are from the 2007 to 2009 Canadian Health Measures Survey. The physical activity of a nationally representative sample was measured using accelerometers. Data are presented as time spent in sedentary, light, moderate and vigorous intensity movement, and in steps accumulated per day. An estimated 9% of boys and 4% of girls accumulate 60 minutes of moderate-to-vigorous physical activity on at least 6 days a week. Regardless of age group, boys are more active than girls. Canadian children and youth spend 8.6 hours per day-62% of their waking hours-in sedentary pursuits. Daily step counts average 12,100 for boys and 10,300 for girls. Based on objective and robust measures, physical activity levels of Canadian children and youth are low.

              The reliability of MinimaxX accelerometers for measuring physical activity in Australian football.

              To assess the reliability of triaxial accelerometers as a measure of physical activity in team sports. Eight accelerometers (MinimaxX 2.0, Catapult, Australia) were attached to a hydraulic universal testing machine (Instron 8501) and oscillated over two protocols (0.5 g and 3.0 g) to assess within- and between device reliability. A static assessment was also conducted. Secondly, 10 players were instrumented with two accelerometers during Australian football matches. The vector magnitude was calculated, expressed as Player load and assessed for reliability using typical error (TE) ± 90% confidence intervals (CI), and expressed as a coefficient of variation (CV%). The smallest worthwhile difference (SWD) in Player load was calculated to determine if the device was capable of detecting differences in physical activity. Laboratory: Within- (Dynamic: CV 0.91 to 1.05%; Static: CV 1.01%) and between-device (Dynamic: CV 1.02 to 1.04%; Static: CV 1.10%) reliability was acceptable across each test. Field: The between-device reliability of accelerometers during Australian football matches was also acceptable (CV 1.9%). The SWD was 5.88%. The reliability of the MinimaxX accelerometer is acceptable both within and between devices under controlled laboratory conditions, and between devices during field testing. MinimaxX accelerometers can be confidently utilized as a reliable tool to measure physical activity in team sports across multiple players and repeated bouts of activity. The noise (CV%) of Player load was lower than the signal (SWD), suggesting that accelerometers can detect changes or differences in physical activity during Australian football.
