The purpose of this study was to investigate the effect of a course of aerobic exercise and vitamin D supplementation on the psychomotor function of elderly women with sleep disorders. Based on this, 42 people were selected in an accessible and targeted manner with an age range of 60-70 years. They all suffered from insomnia. Subjects were randomly divided into four groups: aerobic exercise, aerobic exercise-vitamin D supplement, vitamin D supplement and control group. Vitamin D intake in both groups was taken as 2000 units daily. The Physical Activity Readiness Diagnostic Questionnaire (PARQ) was used to know the level of physical fitness of the subjects and the Gibson 24-hour diet recall questionnaire the day before the pre-test and post-test. The Pittsburgh Sleep Quality Scale was used to extract the sleep profile. COG psychomotor test was also used to assess cognitive and mental components and information processing. The results showed that the aerobic, supplement and aerobic-supplement groups had a significant improvement in selective attention and reaction time. Also, the aerobic-supplement group had a significant improvement in selective attention and reaction time compared to the aerobic group and the supplement group. Aerobic exercise along with vitamin D supplementation seems to improve the motor and motor function of older women. Therefore, vitamin D supplementation and aerobic exercise in interaction are recommended for older women.
