What does Your Activ8rlives Body Analyser Measure?
Bone Mass %
Similar to Muscle Mass percentage, understanding changes in our Bone Mass % can be useful, especially during
weight reduction programme.
Body Mass Index (BMI)
BMI is an index of weight-for-height that is routinely used to classify underweight, overweight and obesity in adults.
The Activ8rlives Body Analyser Smart Scales calculates our BMI value for us. The BMI categories shown in the chart
on Page 10 are recognized by the WHO (World Health Organization) and can be used to interpret our BMI value.
The Body Analyser is not calibrated to determine the BMI for children, pregnant women or professional athletes.
Basal metabolic rate (BMR)
BMR is the amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive
state (meaning that the digestive system is inactive, which requires about twelve hours of fasting).
The release of energy in this state is sufficient only for the functioning of the vital organs, such as the heart, lungs,
brain and the rest of the nervous system, liver, kidneys, sex organs, muscles and skin. BMR decreases with age and
with the loss of lean body mass. Increasing muscle mass increases BMR.
Water or Hydration
Total Body Water (TBW) as a percentage gives us an understanding of our hydration level. Water is a vital element
in the majority of the body's functions and can be found in every cell, tissue, and organ.
A healthy TBW% needs to be maintained to ensure that we are operating at maximum efficiency. Hydration levels
fluctuate throughout the day, so use this measurement as a guide and not your absolute. Note that eating large
meals, drinking alcohol, menstruation, illness, exercising and bathing may cause variations in your hydration level.
When starting a diet or exercise programme, it is important to stay hydrated to maximise the positive effects.
Optimal hydration levels based on population data are:
Female 45-60% Male 50-65%
