BioTrainer™ Activity Monitor
The BioTrainer is not a Gadget or Pedometer!
Unquestionably, the BioTrainer is the most unique, advanced, and affordable exercise monitor available today. This compact and personal companion contains a powerful microcomputer and a tri-axial motion sensor called an accelerometer. It is this accelerometer that sets the BioTrainer apart from the rest of the crowd.
How is the Biotrainer better than a pedometer?
Although pedometers are very cost effective, their main disadvantages are that they do not record the intensity (how hard) or velocity of your body movements, nor do they have memory storage, which restricts their use to simply counting steps. Some pedometers attempt to measure calories burned, but this is only an estimate, which most often gives inaccurate results.
A simple pedometer only counts the number of times a person moves up and down. Most pedometers use a simple spring suspended lever arm (sensor) that moves up and down and makes contact as you walk. As the pedometer moves up, it reports a value of 1. As it moves down, it reports a value of 1, and so on. These are the “steps”. Because a pedometer only measures how many times a person goes up and down, this means that it cannot tell the difference between someone who is standing up and down on their tippy toes and someone who is doing jumping jacks! As you can tell, this can lead to huge variations and possible misreporting of actual energy expenditure.
Unlike pedometers, the BioTrainer utilizes a tri-axial accelerometer that calculates actual intensity of movement, not just “steps”. A tri-axial accelerometer measures intensity of movement in three planes; up and down – front to back and side to side. This allows the BioTrainer to capture activity and movements in every direction a person moves!
The BioTrainer stores this intensity data and accurately computes your physical motion into activity counts; and, secondly, converts the energy you expend into actual calories burned. Whether you’re sitting at your desk, puttering around the house or exercising, each and every movement of your body is captured by the BioTrainer's accelerometer.
So for those who want an accurate account of all their daily physical activity, the BioTrainer is in a class by itself. Whether you’re sitting at your desk, puttering around the house, or exercising, each and every movement of your body is captured, recorded, and reported back by the BioTrainer.
The BioTrainer in Action
The following will recount a recent comparison test between a pedometer and a BioTrainer user:
Two people were instructed to walk; one with a pedometer set to measure calories burned and the other wearing a BioTrainer. After comparing the results of a 1/2 hour walk, at a pace of about 4 mph, the walkers both had their respective monitors clipped to the same position at their waist.
At the end of the workout, the pedometer walker read that she had burned over 1,000 calories, but the BioTrainer walker reported 201 calories burned. As both walkers were about the same height and weight (150 lbs), published calorie burn charts indicate that for this walking speed and distance, the average calories burned should be in the range of 190 to 202. Obviously, while the BioTrainer was right on the money, the pedometer was not counting correctly or was incorrectly adjusted or programmed thus producing an 80% error.
This type of recording error highlights the advantages and precision of the BioTrainer monitor. It never needs programming or adjustments and each unit is built and tested to a factory standard.
