a. 12*6=72
b. 220-21=199
c. 129-150 range.
2. Aerobic metabolism, uses fats, proteins and carbohydrates that are oxidized and turned into carbon dioxide and water. Anaerobic metabolism, uses only carbohydrates and enters the fluid, or cytoplasm, of the cell and is turned into lactic acid. Aerobic exercises are running, biking, and swimming, whereas anaerobic exercises are sprinting, jumping, weight training.
3. My activity is considered lower intensity because it is less than 75% of my max heart rate. Whereas this activity is high intensity for my friend because their heart rate is higher than 75% of their max heart rate.
4. I would be relying more on carbohydrates than fats
where as my friend would be relying more on fats instead of carbohydrates. Fat is higher than carbohydrates, so my friend is needs more calories because her body is working harder whereas my body is not working as hard, so I am using more carbohydrates, instead of fats.
5. A deficit in energy balance lead to weight loss because that number of calories used is more than the number calories that are being consumed so the body has to find the energy from somewhere else in the body. If you are consuming less calories your body is going to use stored fat to compensate for not having enough calories.
6. At a running pace of 6 mph the person would burn 227 calories and at 10 mph would burn 363 calories. The running at the faster pace would be a higher intensity and the slower pace would burn more fat as the energy source, but the fast pace burns the most calories total.
7. Wendy needs to eat about 930-1085 grams of carbohydrates and 186-217 grams of protein. And Elsa needs to eat 1644-1781 grams of carbohydrates and 219.2-232.9 grams of protein. Carbohydrates provide whereas protein are for repairs in our body so strength athlete don’t have as much need for energy and repair as endurance athletes need. That is why there is a difference between the power and endurance athletes.
