A quick trip down the sports nutrition aisle at your local grocery store quickly brings to light how many products are sold to improve sports performance and health. Each product has been specially designed to do something for your body. Some products are designed to replenish your electrolytes after a heavy workout while others are designed to help rebuild your muscles after a strenuous workout. However, have you ever wondered if the claims made by these products are accurate? This is something that you can test with your science fair project.
Protein bars are marketed to two specific demographics, people who want to lose weight and people who want to build muscles. The protein bars that are marketed to people trying to lose weight claim that they are able to curb your appetite and to provide your body with lean protein to help encourage weight loss. The protein bars that are marketed to people who are trying to build muscle claim that they provide a quality protein source that will enable the person to build more muscle.
Science Fair Topics
There are a couple of angles that you can take when developing this topic into a science fair project. The first angle is to focus on the weight loss claims and the second option is to focus on the muscle building properties of the bars. If you select the weight loss claims to test then you will need to select people to test that are trying to lose weight and if you select the muscle building claims then you will need to experiment with people who already are training to build muscle.
Testing Weight Loss Claims
The first direction that you can take in a protein bar science fair project is to see how effective it is at aiding in weight loss. To start with you will need to recruit two groups of dieters. The first group will be your control group. They will follow a healthy diet plan, like the Zone, but they will not supplement that diet with protein bars. The second group will be the test group. They will follow the same diet plan as the control group, however, they will add protein bars to their diet as a snack once a day.
To start the experiment both groups will be weighed and measured. They will then be given diet and exercise instructions. They will be given a diet journal to keep each day. This journal will include what they ate, how much they exercised and how they felt. At the end of weeks 1, 2, 3 and 4 the groups will be weighed and measured. After the 4th weigh in the data will be analyzed to determine if protein bars are aiding in the weight loss of the test group.
