Increased physical activity, along with the achievement and maintenance of energy balance, has emerged as important personal health goal for the 21st century. It is well understood by fitness and health professionals that many leading health problems are caused or aggravated by physical inactivity and the consequences of consuming more calories than are expended. The obesity epidemic and its associated problems are testimony to the fact that a sedentary lifestyle and being overweight contribute to a poor quality of life, and in many cases, premature death.
Healthcare professionals and physically inactive individuals all acknowledge the need to improve and sustain exercise and eating behaviors. These individuals have also noted the lack of tools to assist in the accurate and objective measurement of total energy expenditure and physical activity durations. For example, in order to lose weight, you must first be able to accurately quantify levels of activity, total energy expenditure and daily caloric intake. Only then can you begin to implement the proper changes necessary to your daily routines to help you increase activity levels and manage your caloric intake.
Until recently, there was not an easy-to-use, accurate device to routinely assess metabolic physical activity and energy expenditure outside of the laboratory. However, researchers are now using integrated systems that deliver information on energy expenditure and broad, lifestyle data. Today, multi-sensor devices are being used that can accurately and reliably measure various physiological signals and states – including: physical activity, steps, energy expenditure, and the wearer’s activities (e.g. running, walking, sleep, etc) – which has significant potential in making lifestyle changes to improve health.
These systems collect physiological data which is transferred to a computer. Data is stored in a central location and/or posted on a secure website that is accessible to participants and fitness instructors. This provides a means for individuals to visualize energy balance in a real-world environment. It is well-recognized that regular and accurate self-monitoring in the free-living environment can provide important feedback that increases self-awareness – the prerequisite for healthy decision-making and long-term lifestyle change.
These new devices on the market can revitalize health clubs and give new life to member programs. For club members, it’s a simple and effective way to manage their weight. For club owners, it’s a cost-effective way to increase member compliance and results, as well as a new revenue stream from current and new members. These new, innovative systems are being embraced by consumers, fitness professionals and the country’s leading experts.
