The following equations estimate the calories burned when exercising (source):
Men: Calories = [(Age x 0.2017) - (Weight x 0.09036) + (Heart Rate x 0.6309) - 55.0969] x Time / 4.184
Women: Calories = [(Age x 0.074) - (Weight x 0.05741) + (Heart Rate x 0.4472) - 20.4022] x Time / 4.184
Given age (years), weight (pounds), heart rate (beats per minute), and time (minutes), output calories burned for men and women. If the input is 49 155 148 60, the output is:
Men: 489.777 calories
Women: 580.94 calories
