A la luz de la importancia de la actividad física regular como un elemento clave en la prevención de muchas enfermedades, se reportan a continuación los resultados del estudio realizado con un aparato para ejercitarse en la casa. 22 estudiantes universitarios jóvenes, aparentemente saludables, participaron en el estudio. Se midió el efecto agudo de 10 minutos de ejercicio con el dispositivo sobre la frecuencia cardíaca, el costo energético y la circulación periférica en las piernas. Se contrastan los resultados obtenidos con las afirmaciones que se hacen en distintas versiones de publicidad del aparato en cuestión. No se obtuvieron efectos fisiológicos agudos significativos de la utilización del dispositivo durante 10 minutos continuos: la frecuencia cardíaca aumentó apenas 8 latidos por minuto con respecto al reposo y la temperatura cutánea no varió o más bien disminuyó. El costo energético no fue significativamente mayor mientras se usaba el dispositivo en comparación con la condición de reposo. Estos resultados sugieren que aquellas personas que utilicen este dispositivo en sustitución de la actividad física regular estarán sacrificando beneficios importantes para su salud.  Abstract. The importance of doing regular physical activity (exercise) as a key element in the prevention of several diseases is well known. The following experiment was performed to evaluate the acute physiological effects of a home-exercise machine on 22 young, apparently healthy, university students. While the individuals exercised in the machine for ten (10) minutes, measures of heart rate, energy expenditure and peripheral circulation to the legs were taken and recorded. The results were contrasted against the claims made in different ads promoting the selected apparatus. There were no significant acute physiological effects resulting from the utilization of the machine during a 10-minute period. Heart rate increased only 8 beats per minute (bpm) from baseline and the temperature measured on the legs showed no variation or was even reduced. Energy expenditure was not significantly higher while using the device in comparison with the resting condition. These results suggest that consumers using this home-exercise equipment as a substitute of performing regular physical activity will be sacrificing important health benefits.

INTRODUCTION The use of home exercise equipment is increasing and treadmills are becoming more popular. This has brought with it an emerging but preventable problem. We present our experience, highlight the importance and promote public awareness of this type of injury. To our knowledge this has not been reported previously in the UK. METHODS A retrospective review was conducted of the medical records at two regional burn units of children who sustained treadmill-related injuries between July 2003 and July 2009. Data on patient demographics, mechanism of injury, management, surgical intervention and outcome were recorded. RESULTS Twenty-nine children (15 boys, 14 girls) sustained treadmill-related injuries. The mean age was 3.8 years (range: 1–13 years). All injuries occurred at home and the majority of children trapped their hand under the running belt when an adult was using the machine. Most of the injuries were to the upper limb (97%) with less than 1% of the total body surface area burnt. More than two-thirds of patients had deep burns and 17 (58%) required surgical intervention. Five patients developed hypertrophic scars. All patients achieved a good functional outcome. CONCLUSIONS Treadmills can pose a significant danger to children. These injuries are preventable. Regulatory authorities, manufacturers and parents should take steps to prevent this emerging health problem.

The current paper describes research that is aimed at elucidating our understanding of media technology factors that may help users of exercise equipment to stay motivated for doing regular workouts. In particular, we investigated the effects of immersion and coaching by a virtual agent on intrinsic motivation and the sense of presence of participants cycling on a stationary home exercise bike. A basic two-by-two within-subjects experimental design was employed whereby participants were presented with a virtual racetrack with two levels of immersion (high vs. low) and two levels of a virtual coach (with vs. without). Results indicate a clear positive effect of immersion on both motivation and presence. The virtual coach significantly lowered the perceived control and pressure/tension dimensions of intrinsic motivation, but did not affect the enjoyment dimension. The presence of the virtual coach also reduced negative effects associated with VEs, such as feeling dizzy or nauseated.
