Exercise and cardiorespiratory fitness on subjective memory complaints

ABSTRACT The purpose of this study was to examine the association between exercise and estimated cardiorespiratory fitness on subjective memory complaints in young adults. Four-hundred and 64 young adult college students (18–35 yrs) completed an online survey. Exercise behavior was assessed from the Physical Activity Vital Signs Questionnaire. Cardiorespiratory fitness was evaluated from an algorithm that included an assessment of age, gender, body mass index, waist circumference, resting heart rate, habitual physical activity behavior, and smoking status. Subjective memory complaints were assessed using the Prospective-Retrospective Memory Questionnaire. Subjective memory complaints were common among this young adult sample. However, exercise was not statistically significantly associated with prospective (β = −0.002, P = 0.25) or retrospective (β = −0.001, P = 0.26) memory complaints. Results were similar for cardiorespiratory fitness. In conclusion, we did not observe an association between exercise and estimated cardiorespiratory fitness on subjective memory complaints in young adults.
