  Figure 2. (A) Following 8 weeks of aerobic-exercise training, the results indicate an improvement in cognitive function as there is decrease in trend in P300-latency (latency). (B) Following 8 weeks of aerobic-exercise training, the results indicate an improvement in cognitive function as there is an increase in trend in P300-amplitude (amplitude). (C) Following 8 weeks of aerobic-exercise training, the results indicate an improvement in cognitive function as there is decrease in trend in trail making test part-A (TMTA). (D) Following 8 weeks of aerobic-exercise training, the results indicate an improvement in cognitive function as there is a decrease in trend in trail making test part-B (TMTB). (E) Following 8 weeks of aerobic-exercise training, the results indicate an improvement in cognitive function as there is increase in trend in mini mental status examination (MMSE) score. (F) Following 8 weeks of aerobic-exercise training, the results indicate an improvement in cognitive function as there is decrease in trend in everyday cognition questionnaire (ECog) scores.
