A-120 Cognitive Function and VO2max following HIIT Exercise Intervention

Abstract Objective: To determine if an 8-week HIIT exercise intervention would improve VO2max and cognitive function in older sedentary women. Method: Eleven women between the ages of 60 75 participated intervention. At baseline, participants were administered a test neuropsychological battery, which assessed both global functioning as well specific domains processing speed, visual memory, attention, language executive function. Composite scores for each domain calculated using average z-scores. Procedures performed at baseline conducted again following Results: Following intervention, there was mean increase 3.89 ml/kg/min (p<.0001) compared to baseline. Cognitive data showed total composite z-score significantly improved from (M=-0.71, SD=0.58) follow-up (M=0.20, SD=0.61). Visual memory (M=-0.37, SD=1.97) also significant (M=0.27, SD=0.83) along with improvement (M=-0.04, SD=0.60) (M=0.25, SD=0.59), all p <.05. In addition, correlated (r= 0.65; p< .05) (r=.66; p<.05). Conclusions: We found that 8-weeks sufficient Total z-scores after VO2max. These findings highlight need explore further mechanisms drive effects on cognition across diverse populations.
