Which technology would you prefer to use in your club?
Technology A is Bio Impedance. Technology B is Near infrared. Bio inpedance measures body water level using electrical conductivity. Based on the premise that lean body mass contains more water than fat mass, the more water you have in your body at the time of measurement, the greater the conductivity of the electrical current and the leaner you will test. A major concern with the technology is that a persons body water level fluctuates hourly based on the foods they eat, their activity, and other biological factors including a woman's menstruation, illness and disease.
The day of Jane's follow up test, she, like many people on the road to fitness, exercised for 30 minutes on the tread mill, drank a cup of coffee for breakfast, and had a drink of tea during lunch. Additionally, she was experiencing her menstrual cycle. Each of these factors, independently, will affect the accuracy of bio impedance measurement because they directly influence a persons hydration level. Jane is not only demotivated by her bio impedance results, she is upset.
Near infrared, opposite to bio impedance directly measures body fat, not body water. Jane's results in her follow up test accurately illustrate her achievement in attaining her fitness goals. Her motivation and excitement continue and spread throughout the health club and everyone she meets
