Exercise provides individuals with various physical benefits, improving cardiovascular health, strengthening bones and muscles, and increasing flexibility and mobility. Additionally, exercise promotes numerous mental benefits, reducing stress, improving mood, and enhancing cognitive function. Unfortunately, with various types of exercise, ranging from strength training to interval training, it's difficult for individuals to choose the one that will provide the best results. In this study, we decided to examine the cognitive effects of interval training compared to a prescribed fitness plan amongst UWEC's Community Fitness Program (CFP) members. To do this, participants of the interval training and the control group were asked to commit to 2-3 workouts a week and took a baseline test, examining their cognitive abilities. After 4 weeks, the two groups were retested, took a week-long break, and resumed training. Through this experiment, our group hoped to discover if interval training, compared to a prescribed fitness plan, had a greater impact on cognitive function, providing more insight into the vast world of exercise, potentially directing new exercising individuals looking to seek higher cognitive function or redirecting veteran exercisers to help them realign their goals.
