Purpose The overall purpose/hypothesis of the article, was it to find out how physical activity is linked to the preservation of neurocognition, but more specifically to address the fundamental question-- “does exercise improve cognition?” (Masley et al., 2009). The secondary reason for this study is to use a technological method to determine the field of cognitive domains, in relation to memory, mental speed, reaction time, attention, and cognitive flexibility. Subjects The subjects from this study were volunteers from the Carillon Wellness Center, St Anthony’s Hospital, St. Petersburg, Florida. There were 91 male and female subjects who were between the ages of 18-70. No subjects have a history of elevated heart levels or any major…show more content…
Findings and Statistics The comparison between demographic and physiological data was found on Table 1. The statistics showed that there was no significant difference between both the control group and the combined intervention group in relation it age, BMI, years of education, and VO2max fitness. The only shown difference was gender, a higher percentage of women were added onto the study. The study showed that there was no statistical significant change in VO2max levels. “VO2max levels had increased by 6.5% in the control group, 12% in the moderate intervention group, 17.3 % in the combined intervention group, and 21.3 % in the high exercise intervention group” (Masley et al., 2009). The independent t-test showed the comparison between the control group and the high exercise group was rather significant, with a p value of 0.53. Also, the Spearman rank correlation coefficient compared the change from the control, to the moderate, to the high exercise groups, with a coefficient of 0.23 and a VO2 max p value of 0.06. Neurocognitive data that was analyzed by MANOVA, was collected in Table 2. For this study, there was a high significant difference is the observes psychomotor speed, attention and cognitive flexibility, with a p value of 0.03. When t-test compared the change in the combined intervention group with the controlled group, only cognitive flexibility
