with better motor abilities may find it easier to be physically
active and may be more likely to engage in physical activity
compared with peers with poorer motor competence. The purpose of
this study was to examine the relationship between motor
proficiency and physical activity in 8- to 10-year-old children.
Self-efficacy toward physical activity was also assessed. Sixty-
five children (34 girls and 31 boys) were studied. Children's
physical activity was assessed by the Manufacturing Technologies
Incorporated/Computer Science and Applications Incorporated
model 7164 accelerometer, and their motor proficiency was

The Children's Self-Perceptions of Adequacy in and Predilection
for Physical Activity scale measured children's self-perceptions
of adequacy in performing and desire to participate in physical
activities. Children's motor proficiency was positively
associated with activity co
