Working out can sometimes be a pain, you have to fit it in between classes, or after work, or trek across campus to even get to one that works best for you. To top things off, finding time during mid-terms or finals makes it 10 times harder to exercise, but what if I told you that working out can help get you better scores on your tests?
A 2009 experimental study showed that there were significant improvements with memory function with rodents (either rats or mice). Along with that, several other functions that were discovered within the nervous system which had improvements as well. Not only were the benefits displayed with the animals, they were also discovered with humans as well. The link between cardiovascular work outs (running, walking, etc.) and positive brain function were apparent. The information was collected as mean of an MRI’s. After the subjects were asked to perform cardiovascular they then were put through a series of mental test.
In other words, your cognitive ability to learn and apply knowledge is increased when you work out. However, there are limitations of the study such as the age range at which the participants are at the time of the study. The study uses children from ages 9-10 all of different fitness levels. looking at that alone, you could ask numerous questions about how the study was conducted. For example, How does a child compare to a college student in terms of cognitive ability. Another questions could be, Since college students have more schooling, could their adaption to studying habits cause them to have different results over what the children might do? Could there be a correlation to a child’s brain verse a college brain that is being over looked? Though the study make be a bit of a leap using children to compare to the entire population, further research is also showing links to the brains connection with fitness and grades. What about a Confounding variable, Could it be that, students who care more about their physical appearance are more likely to also care more about their grades? This is a variable that was not mentioned however, when it comes to the study, this could effect the data!
Further research however does provide evidence that fitness levels in college students correlates to their grades! in an article from Purdue University published in 2013, it gives credible data supporting grades and physical fitness. Not only was the GPA higher in those who worked out in comparison to those who did not, it also went on to test the amount of time spent in the gym and how it effected the GPA as well. Even students that only went a few times in the semester, those students overall had better GPS than students that had not worked out at all. Time management was also factored into the data testing which helped eliminate any type of unseen 3rd variables.
In closing, based off the studiess talked about, the chances that your grades are directly linked to fitness could be due to chance, but evidence provides strong instances where working out could lead to better GPA’s.
