Objective Recording

The ActiReg® (PreMed AS, Oslo, Norway) system is unique in using combined recordings of body position and motion alone or combined with heart rate (HR) to calculate energy expenditure (EE) and express physical activity (PA). The ActiReg® has two pairs of position and motion sensors connected by cables to a battery-operated storage unit fixed to a waist belt. Each pair of sensors was attached by medical tape to the chest and to the front of the right thigh respectively. The collected data were transferred to a personal computer and processed by a dedicated program ActiCalc®. Calculation models for EE with and without HR are presented. The models were based on literature values for the energy costs of different activities and therefore require no calibration experiments. The ActiReg® system was validated against doubly labelled water (DLW) and indirect calorimetry. The DLW validation demonstrated that neither EE calculated from ActiReg® data alone (EEAR) nor from combined ActiReg® and HR data (EEAR–HR) were statistically different from DLW results. The EEAR procedure causes some underestimation of EE >11 MJ corresponding to a PA level >2·0. This underestimation is reduced by the EEAR–HR procedure. The objective recording of the time spent in different body positions and at different levels of PA may be useful in studies of PA in different groups and in studies of whether recommendations for PA are being met. The comparative ease of data collection and calculation should make ActiReg® a useful instrument to measure habitual PA level and EE.

Activity Energy

Background:The assessment of physical activity (PA) and energy expenditure (EE) in youth is complicated by inherent variability in growth and maturation during childhood and adolescence. This study provides descriptive summaries of the EE of a diverse range of activities in children ages 7 to 13.Methods:A sample of 105 7- to 13-year-old children (boys: 57%, girls: 43%, and Age: 9.9 ± 1.9) performed a series of 12 activities from a pool of 24 activities while being monitored with an indirect calorimetry system.Results:Across physical activities, averages of VO2 ml·kg·min-1, VO2 L·min-1, EE, and METs ranged from 3.3 to 53.7 ml·kg·min-1, from 0.15 to 3.2 L·min-1, from 0.7 to 15.9 kcal·min-1, 1.5 MET to 7.8 MET, respectively.Conclusions:The energy costs of the activities varied by age, sex, and BMI status reinforcing the need to consider adjustments when examining the relative intensity of PA in youth.

Manual Wheelchair

The purpose of this study was to develop a compendium of wheelchair-related physical activities. To accomplish this, we conducted a systematic review of the published energy costs of activities performed by individuals who use wheelchairs. A total of 266 studies were identified by a literature search using relevant keywords. Inclusion criteria were studies utilizing individuals who routinely use a manual wheelchair, indirect calorimetry as the criterion measurement, energy expenditure expressed as METs or VO2, and physical activities typical of wheelchair users. Eleven studies met the inclusion criteria. A total of 63 different wheelchair activities were identified with energy expenditure values ranging from 0.8 to 12.5 kcal·kg-1·hr-1. The energy requirements for some activities differed between individuals who use wheelchairs and those who do not. The compendium of wheelchair-related activities can be used to enhance scoring of physical activity surveys and to promote the benefits of activity in this population.

ABSTRACTStudies of personal training with integrated electro-stimulation or whole body devices, known in scientific literature as a Whole Body Electromyostimulation (WB-EMS) have multiplied in Spain and Central Europe. WB-EMS centers pose a series of benefits for the use or training with this type of device. One of the benefits promoted is a high-energy expenditure compared to other types of physical activity. In some cases one gets to match 20 minutes from WB-EMS with 3 or 4 hours of intense exercise. A literature review was conducted in order to make a comparison between the energy costs generated by a session of WB-EMS and other activities, methods or training devices. The results show that, at similar intensity, a session of WB-EMS as described in the baseline study, not presents be superior to other activities, methods or training devices. This publicity can change the type or frequency of activities of some users, who motivated by the advertised benefit, could leave or reduce them, with the consequent risk of not to accumulate the minimum of physical activity recommended by the American College of Sports Medicine or the World Health Organization.RESUMENEn España y Centroeuropa se han multiplicado los estudios de entrenamiento personal que cuentan con los dispositivos de electroestimulación integral o de cuerpo entero, conocido en la literatura científica como Whole Body Electromyostimulation (WB-EMS). Los centros de WB-EMS suscitan una serie de beneficios por el uso o entrenamiento con este tipo de dispositivo. Uno de los beneficios promovidos es un elevado gasto energético comparado con otro tipo de actividades físicas. En algunos casos se llega a equiparar 20 minutos de WB-EMS con 3 o 4 horas de ejercicio intenso. Se realizó una revisión bibliográfica con el fin de elaborar  una comparativa entre el gasto energético generado por una sesión de WB-EMS y otras actividades, métodos o dispositivos de entrenamiento. Los resultados muestran que, a similar intensidad, una sesión de electroestimulación integral como la descrita en el estudio de referencia, no presenta ser superior a otras actividades, métodos o dispositivos de entrenamiento. Esta publicidad puede llegar a cambiar el tipo o la frecuencia de actividades de algunos usuarios, quienes motivados por el beneficio publicitado, podrían abandonarlas o reducirlas, con el consiguiente riesgo de no acumular los mínimos de actividad física recomendados por el American College of Sports Medicine  o la Organización Mundial de la Salud.
