Resistance exercise has been shown to be an effective modality in eliciting significant physiological changes, such as central and peripheral fatigue. We hypothesized that the chemical and electrical changes associated with central fatigue will result in impaired cognitive function. This study recruited 10 recreationally trained men who served as their own control. The participants underwent two weeks of testing, including one baseline visit and one test visit. During the test visit, participants completed the Automated Neuropsychological Assessment Metrics (ANAM), an assessment of cognitive function before and after six sets of ten repetitions of a back squat. Analysis determined that the back squat protocol elicited fatigue and influenced cognition. Significant decreases were observed in mean reaction time and mean reaction time for correct answers compared to pre exercise values, p = 0.006 and p = 0.004, respectively, for the coded substitution (delay) (CDD). Spearman correlation analysis indicated a relationship between the change score for the mean reaction time of correct answers and the total time spent working, r (9) = 0.742, p = 0.014. For the go/no go (GNG) test, significant decreases were observed in mean reaction time and mean reaction time for correct answers from pre to post test, (p = 0.004, p = 0.004, respectively). For the mathematical processing (MTH) test, a significant decrease was overserved in mean reaction time and mean reaction time for correct answersiiifrom pre to post exercise values, (p = 0.004, p = 0.004, respectively). CCD throughput significantly decreased from pre to post exercise protocol (p = 0.006), while throughput for MTH significantly increased from pre to post, (p=0.004). These results support both the transient hypofontrality hypothesis through declined performance in a complex cognitive task while improved performance in simpler cognitive task. These results also support the inverted-U hypothesis, with a decline in cognition occurring in the beginning of the cognitive assessment and an improved cognitive performance towards the end. Future research using advanced imaging techniques such as EEG and fMRI should be conducted to determine whether the effects of fatigue were task or time dependent. 2018-09-04 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1523634769121426 http://rave.ohiolink.edu/etdc/view?acc_num=osu1523634769121426 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
