how to convert accelerometer data to metabolic equivalents(METS)??

hi all i would like to ask if how do i convert accelerometer data to metabolic equivalents(METS)??

by the way I am using this formula:

[B]Total Calories Burned[/B] = Duration (in minutes) X (MET X 3.5 X weight in kg)/200

i got that formula from this site http://www.exercise4weightloss.com/calories-burned-during-exercise.html"

what i want to do is convert XYZ data to METS equivalent so that i can substitute it to METS variable in the formula above..
example if i have this data:

x: 202
y: 215
z: 5

what is the formula? I search on www but i didn't get what i need.. ;(

I knew that it is now accurate but it doesn't matter..
pls give me some idea. IM totally bad in math and physics... hehe thanks

hi.. do u have any idea with this??

helo?

The problem is that there isn't a direct equivalent. You'll just have to look up the activity you were doing on a table, and use that value.

Hi there,

Converting accelerometer data to metabolic equivalents (METS) is a complex process that requires a thorough understanding of physics, physiology, and mathematics. METS is a unit of measurement used to quantify the intensity of physical activity and is defined as the ratio of the metabolic rate during an activity to the resting metabolic rate. In order to convert accelerometer data to METS, you will need to follow these steps:

1. Collect accelerometer data: The first step is to collect accelerometer data using a device such as a fitness tracker or a smartphone app. This data will include measurements of acceleration in three directions (X, Y, and Z) and will be recorded at a specific frequency (e.g. every 1 second).

2. Calculate the magnitude of acceleration: Accelerometer data is typically recorded in the form of three-dimensional vectors (X, Y, and Z). In order to convert this data to METS, you will need to calculate the magnitude of acceleration by taking the square root of the sum of the squares of the three components (i.e. √(X^2 + Y^2 + Z^2)).

3. Convert magnitude of acceleration to METS: Once you have calculated the magnitude of acceleration, you can use it to estimate the intensity of physical activity in METS. This can be done using a calibration equation specific to your accelerometer device and the type of physical activity you are measuring. These equations can be found in research literature or provided by the manufacturer of your device.

4. Substitute METS into the formula: Once you have calculated the METS value for your activity, you can substitute it into the formula you provided in your post to calculate the total number of calories burned during the activity.

It is important to note that the accuracy of this conversion will depend on the accuracy of the calibration equation and the assumptions made about the individual performing the activity (e.g. weight, age, gender, etc.). Additionally, this process may require some level of expertise in data analysis and interpretation. If you are not confident in your understanding of the concepts and calculations involved, it may be best to seek the help of a trained professional.
