This study seeks to replicate and extend research on the stress proces
s by examining the relationships among stress, social support, physica
l exercise, and depressive symptoms with data provided by a recent nat
ionwide survey of older adults in Japan. The findings reveal that more
frequent physical exercise is associated with less psychological dist
ress. Moreover, the data suggest that some (but not all) types of stre
ssors tend to diminish the frequency of physical activity. Finally, an
d perhaps most important, the results reveal that social support tends
to promote more frequent exercise. This can occur in two ways. First,
more emotional support was related to better exercise habits. In addi
tion, negative interaction was also associated with more frequent exer
cise, suggesting that informal social sanctions can foster positive he
alth behaviors.
