Over the past two decades children's fitness levels may have declined (Ross and Pate, 1987; Ignico, 1990; Leung, 1995). Currently, attention is being directed to young children's gross motor performance, assessment procedures and program planning issues. This paper will present findings of a study which investigates the gross motor proficiency of young children in Hong Kong. The Bruininks-Oseretsky Test of Motor Proficiency (Subtests 1-5) was used to assess the gross motor proficiency of 320 children aged 5 to 6 years. Gross motor proficiency was measured in terms of their performance on running speed and agility, balance, bilateral coordination, strength and upper-limb coordination.
