Physical Activity and the Adolescent Brain

Effects on the Brain- Improves structure, function, and connectivity of your brain [6]- Inceases blood flow whichimproves cardiovascular health [6]- Releases neurotrophic factors like BDNF witch stimulates growth of new neurons [6]

Good Physical Brain Excercises- Aerobic 3 days a week [2]- Muscle Strength 3 days a week [2]-Bone Strength 3 days a week [2]- Running on a treadmill increases problem solving skills [3]- Dancing can help maximize cognitive function and muscle memory through practice [6]

How Much?-CDC ( Center for Disease Control) [2] recomends that adolescents get at least 60 minutes of physical activity each day.-The Daily Beast [4] recomends that children and adolescents get 30 minutes of physical activity each day- Fit.Web [3] recomends that children and teens get at least 30 minutes of physical activity a day

ProblemCan I increase my brain health by getting 30 minutes of physical activity each day?

HypothesisIf I get 30 minutes of physical activity each day, then my brain health will improve.

ExperimentDay without gymnastics or gym class:1. Go through day normally and go outside at some point during the day2. Record data at end of dayDay I have gym class or gymnastics:1. Go through day normally 2. Go to gym class or gymnastics at normal time3. Record data at end of dayDo every day for 13 days

Research

AnalysisDuring my experiment I met my goal of 30 minutes of physical activity each day. On some days I got a lot of physical activity while on some other days I just barely did it. From my first test to my final test my test scores improved a pretty decent amount. For my 2nd test my scores went down from 43 to 26 in fact recall and level 9 to 7 in memory. I don't really know why my scores went down that day because everything was normal. From the first test to the second test my amount of physical activity each day was 5.5 hours, 1 hour, and 2.5 hours. I noticed that if we tested the day after I had gymnastics my scores went up more than they did if we tested on a day that I didn't have gymnastics. I also saw that after my 2nd test my scores kept steadily going up.

ConclusionI was trying to answer the problem "Can I improve my brain health if I get 30 minutes of physical activity each day?" My hypothesis was that if I get 30 minutes of physical activity each day, then my brain health will improve. My experiment supported my hypothesis. My data shows thaton the first baseline test my fact recall was 43 and my memory was 9. For the final test my fact recall was 55 and my memory was 12. This shows that both my fact recall and my memory increased. Based on this data, yes, I can improve my brain health if I get 30 minutes of physical activity each day. On the 2nd test my scores went down to 26 in fact recall and 7 in memory. This was most likely caused by distractions in the room and that I didn't get much sleep the night before. Next time I will try to make sure to keep my sleep, stress, and nutrition levels normal so that I can focus on how physical activity affects the brain without a bunch of other things being abnormal. In the future I want to see if my scores improve if I increase all 4. I want to do physical activity , stress, sleep, and nutrition at the same time. Overall I think that my experiment went well without many errors to throw my data off and my brain health did improve which is a really good thing.
