This study analyzed the effects of motor function and cognitive function on self-perceived fatigue among older worker. Participants were 157 members（133 men and 24 women）of the Silver Human Resources Center in “A” City, Tokyo, who were in charge of outdoor work（weeding and park cleaning）, aged 63-86 years（mean age: 74.2 ± 5.3 years）. The following variables were measured: self-perceived fatigue, motor function, cognitive function, age, sleep duration, air temperature during working hours, physical activity and job control.
It was suggested that motor function and cognitive function were not significantly related to change self-perceived fatigue, but interaction term between both functions was significantly related to change of self-perceived fatigue.（β=-0.07, p=0.004）. Fatigue management methods should be developed to functioning of older workers.
