A TypeScript library with useful functions for health and fitness tracking applications.

Features

This library provides essential functions for processing health and fitness data:

• Heart rate variability (HRV) calculation
• Resting heart rate determination
• Calorie burn estimation
• VO2 Max estimation
• Sleep quality scoring
• Training load calculation
• Abnormal heart rhythm detection
• Recovery score calculation

Installation

npm install

Usage

Build the library:

npm run build

Import functions in your project:

import { 
  calculateHRV,
  calculateRestingHeartRate,
  calculateCaloriesBurned 
} from 'healthtracker';

// Calculate HRV from RR intervals
const hrvValue = calculateHRV([800, 820, 790, 810, 800]);

// Calculate resting heart rate from heart rate data
const restingHeartRate = calculateRestingHeartRate([65, 70, 68, 72, 80, 85, 78]);

// Calculate calories burned during exercise
const caloriesBurned = calculateCaloriesBurned(140, 35, 70, 'male', 45);
