How to Use
TheoricalMaxHeartRate: Returns a number that is the person's maximum theoretical number of beats per minute
const { TheoricalMaxHeartRate } = require('lthrmodule')
console.log(TheoricalMaxHeartRate(23, 'm'))
// Should return 197LTHRZones: Returns a JSON object with the upper bounds heart zones for the user characteristics.
const { LTHRZones } = require('lthrmodule')
console.log(LTHRZones(23, 'm'))HeartRateExtractor: Returns an array of numbers with the heart rate for each iteration of time.
const fs = require('fs')
const { HeartRateExtractor } = require('lthrmodule')
const data = fs.readFileSync('./file.fit', 'UTF-8');
console.log(HeartRateExtractor(data))
// Should return a JSON array of numbers SpeedExtractor: Returns an array of numbers with the speed for each time iteration.
const fs = require('fs')
const { SpeedExtractor } = require('lthrmodule')
const data = fs.readFileSync('./file.fit', 'UTF-8');
console.log(SpeedExtractor(data))
// Should return a JSON array of numbers LTHRZone: Returns a string with the heart zone in which the person is located for the given data.
const { LTHRZone } = require('lthrmodule')
console.log(LTHRZone(23, 'm', 184))
// Should return zone4LTHRZonesPercentage: Returns a JSON object with the heart zones and the percentage of time the user has been in.
const fs = require('fs')
const { LTHRZonesPercentage, HeartRateExtractor } = require('lthrmodule')
const data = fs.readFileSync('./file.fit', 'UTF-8')
console.log(LTHRZonesPercentage(23, 'm', HeartRateExtractor(data)))At this time the only devices compatible are Decathlon HR Dual Band and systems that use the same data names.
And only cycling and running are available as sports.
