Often times after a big meal, we may find ourselves considering how much we need to exercise to work off what we just ate. In this exercise we will actually compute it. 1) Oxygen consumption (VO2) can be used as an indicator of exercise intensity, which is closely tied to energy expenditure. In other words, VO2 can be used to approximate how many calories are burned during an activity. The approximate VO2 for walking (on flat land) at a given speed (mph) can be computed as: VO, for walking = 2.68224 x speed + 3.5 The approximate VO, for running (on flat land) at a given speed (mph) can be computed as: VO, for running = 5.36448 x speed + 3.5 2) The calorie burn rate (CBR) is the number of calories burned per minute when doing a certain activity. A simplified way to compute the CBR from VO, and a person's weight (Ibs) is given by the formula: CBR = (2.268 x 10) x VO2 x weight %3D You need to write three (3) versions of a program that calculates how many minutes one needs to exercise to burn off a given amount of food they ate. To calculate the number of minutes required to burn off a given number of calories, simply divide the total calories by the calorie burn rate. In the descriptions for PART A, PART B, and PART C, I use "chicken nuggets" as the food of choice. Assume that chicken nugget has 47 calories each. However, in your program you may use whatever type of food you want. Be sure to look up the amount of calories for that food type (you may try: www.calorieking.com). Disclaimer: Note that these calculations are simple approximations and do not account for all the different individual factors for each person. This exercise (pardon the pun) is intended to help students learn how to write computer programs, not to inform their decisions on how to take care of their physical health. Therefore, do not base any real-life health or fitness program (pun intended) on these calculations. PART C. Make a copy of the previous program and rename the class to FitnessPlanner_3. This time, instead of asking the user how many chicken nuggets he/she ate, ask for how much time the user will have to run or walk. Your program should then tell the user how many chicken nuggets he/she is allowed to eat without accumulating surplus calories, assuming they follow through with their exercise commitment. Also display how many calories will be burned. *** This Fitness Planner program will calculate how much food *** you can eat and how many calories you need to burn off. *** *** What is your weight in pounds? 115 Do you prefer walking or running (W or R)? R What is your average RUNNING speed in mph (6 is typical, a 10-min/mi pace)? 8. How many minutes will you run? Congratulations, you are allowed to eat 7 chicken nuggets. You will burn off 363 calories later.
