“…Este dato contrasta con investigaciones previas que no han conseguido, con una intervención de entrenamiento en circuito mejorar esta variable (Poehlman y col., 2002). Incluso en intervenciones más recientes el entrenamiento con cargas ha disminuido significativamente esta variable (Hunter y col., 2008).…”

“…Morgan y colaboradores encontraron al 85% y 100% de 8 RM respectivamente (10-12 Kj/min) ó 2,4-2,88 kcal/min (Morgan, Woodruff, y Tiidus, 2003 para la pérdida de peso, sobre todo en poblaciones que no pueden realizar actividades cardiodinámicas de mayor gasto. La controversia suscitada en cuanto a la utilidad del entrenamiento con cargas como tratamiento en los programas de pérdida de peso sin combinación con dieta (American College of Sports Medicine, 2009) sigue en pie, ya que las evidencias sugieren que cualquier programa de ejercicio que no se combine con restricción calórica no obtiene los resultados deseados (Bouchard y col., 2009;Del Corral y col., 2009;Hunter y col., 2008;Poehlman y col., 2002).…”

“…para que haya cualquier cambio (American College of Sports Medicine y Thompson, 2010;Beckham y Earnest, 2000). Tan sólo el entrenamiento aeróbico ha sido capaz de mejorar este parámetro (Hunter y col., 2008;Poehlman y col., 2002) y aunque el EC puede provocar aumentos en el gasto energético total diario de hasta un 4% (Hunter, Wetzstein, D Benito, P. J.;. Gasto energético aeróbico y anaeróbico en un circuito con cargas a seis intensidades diferentes.…”

ResumenEl entrenamiento con cargas es una actividad anaeróbica glucolítica intensa y se ha comprobado que el error en las estimaciones del gasto energético en esta actividad varía entre un 13 y un 30%. El principal objetivo de este trabajo es describir la contribución anaeróbica de energía en un circuito con cargas. Doce hombres (20-26 años) y diecisiete mujeres (18-29 años) estudiantes de Ciencias de la Actividad Física y del Deporte realizaron un entrenamiento en circuito de cargas a 6 intensidades diferentes (entre el 30% y 80% de su 15RM). Durante la totalidad de los circuitos se registró el gasto energético aeróbico por calorimetría indirecta, la frecuencia cardiaca con pulsómetro Polar® y la concentración de lactato en sangre capilar para medir la contribución anaeróbica. El incremento que produjo la energía anaeróbica se situó entre el 5,1% y un máximo del 13,5%, lo que hace evidente que medir o no la contribución anaeróbica en el entrenamiento en circuito puede provocar un error medio del 9,65%. Existen diferencias significativas (P< 0,05) entre el gasto energético aeróbico y total (aeróbi-co+anaeróbico) en todas las intensidades, en un circuito de entrenamiento con cargas a intensidades progresivas.Palabras clave: entrenamiento con cargas; gasto energético; lactato; circuito. AbstractResistance training is an intense anaerobic glycolytic activity and has been shown that estimates of energy expenditure in this activity turn out into an error that varies between 13 and 30%. The main aim of this paper is to describe the anaerobic energy contribution in circuit weight training. Twelve men (20-26 years) and seventeen women (18-29 years) students in Science of Physical Activity and Sport performed a circuit training at six different intensities (between 30% and 80% of 15RM). During all the circuits aerobic energy expenditure was registered by indirect calorimetry, heart rate with Polar® monitors and lactate concentration in capillary blood to measure the anaerobic contribution. The increased due to anaerobic energy was between 5,1%, and a maximum of 13,5% which clearly means that to measure or not the anaerobic contribution in circuit training can lead to an average error of 9,65%. There are significant differences (P <0,05) between aerobic energy expenditure and total (aerobic+anaerobic) at all the intensities, in a circuit weight training with progressive loads.

“…[30][31][32][33] As the obese people have a greater BW and FFM, the energy cost of all of their physical activities is bigger than from the overweight people, resulting in a major BW loss. So, we suggest that any weight loss program should pursue the maintenance of the FFM, with exercise sessions at an intensity about 65-80% of the 1RM, (Hunter, 2008) contributing to the body's overall energy expenditure rate (Ravussin et al, 1986). …”

Sport Exerc., 10(4), pp.883-890. Aim. To evaluate the effect of the initial Body Mass Index (BMI) and sex on the velocity of the body weight loss. Methods. The methods used included 180 overweight and obese participants (18 -50 years; Body Mass Index (BMI) >25 and <34.9 kg/m2). Training groups exercised three times per week, and participants from only diet group respected the recommendations about physical activity from American College of Sports Medicine (ACSM), during twenty-four weeks while having 25-30% calorie restriction. Two-way repeated-measures ANOVA was employed to analyze the initial and final body composition by sex and initial BMI. Results. The main finding of this study is that the BW loss is affected by the initial BMI and sex. Conclusion. Body weight loss is affected by the initial BMI and sex, being greater for the obese people than for the overweight one, showing differences between sexes only in the overweight condition. Registered in Clinical Trials Gov.: number NCT01116856.

“…Among its benefits are increased muscular strength and endurance, and reduced blood pressure (Kelley and Kelley 2000). In addition, since resistance exercise raises energy expenditure (EE), it could help prevent weight gain after its loss (Hunter et al 2008). It could, therefore, be of valué during weight loss or weight loss maintenance programs when combined with energy intake restriction and endurance exercise (Kraemer et al 1999).…”

Validation of the SenseWear armband in circuit resistance training with different loads

The use of the SenseWear 1M armband (SWA), an objective monitor of physical activity, is a relatively new device used by researchers to measure energy expenditure. These monitors are practical, relatively inexpensive and easy-to-use. The aim of the present study was to assess the validity of SWAs for the measurement of energy expenditure (EE) in circuit resistance training (CRT) at three different intensities in moderately active, healthy subjects. The study subjects (17 females, 12 males) undertook CRT at 30, 50 and 70% of the 15 repetition máximum for each exercise component wearing an SWA as well as an Oxycon Mobile (OM) portable metabolic system (a gold standard method for measuring EE). The EE rose as exercise intensity increased, but was underestimated by the SWAs. For women, Bland-Altman plots showed a bias of 1.13 ± 1.48 METs and 32.1 ± 34.0 kcal in favour of the OM system, while for men valúes of 2.33 ± 1.82 METs and 75.8 ± 50.8 kcal were recorded.Communicated by Klaas R Westerterp.
