Purpose The purpose of this study was to determine the impact of cognitive fatigue on aerobic output during a 6‐minute walk test (6MWT) in older adults. Methods Healthy older adults (N=9, age= 67.39±4.58 yrs, height=168.01±55.82 cm, weight=60.80±12.41 kg) were involved in 2 days of testing. One day was a 2‐hour protocol of cognitively fatiguing tasks (S3 and S7, continuous performance task (CPT), rapid visual input processing (RVIP),) after which they were tasked to complete a 6MWT at their normal speed and VO2 was measured using the Cosmed Fitmate Pro. The other day, a baseline 6MWT was performed and VO2 were measured. A One‐Sample Kolmogorov‐Smirnov Test to determine distribution of peak VO2 scores prior to performing an independent sample T‐test to determine differences between cognitive fatigue and non‐cognitive fatigue days. Results Results yielded a normal distribution (Mean=871,33, SD=265.89) and T‐test analysis yielded no significant differences (p=.734) between cognitive fatigue and non‐cognitive fatigue days. Conclusion Although analysis yielded no difference in peak VO2 scores between days, it should be noted that 6 out of the 9 subjects had lower peak VO2 on cognitive fatigue days than on non‐cognitive fatigue days. Further research needs to be conducted to determine whether cognitive fatigue does decrease aerobic performance in older adults. This abstract is from the Experimental Biology 2018 Meeting.
