Exploring the motor skill proficiency barrier among children with intellectual disabilities: Analysis at a behavioural component level.

Models of childhood motor development began to emerge in the 1960's. Since then, numerous models have proposed the importance of obtaining a proficient level of fundamental movement skill (FMS) competence during childhood and deemed it to be critical for participation in lifelong sports and physical activity. This study examined FMS at the behavioural component level in children with intellectual disabilities (CwID) (n = 100, 60% boys, aged 5-12 years). Participants were assessed using the Test of Gross Motor Development 3rd edition (TGMD-3) and the balance subtest from Bruininks-Oseretsky Test of Motor Proficiency 2 (BOT-2). For the whole sample, 0% participants mastered all 10 FMS, 1% (n = 1) participants mastered all 4 locomotor skills while 0% (n = 100) participants mastered all ball skills. A multiple regression was carried out to investigate whether the interaction of gender and age was a predictor of FMS proficiency. Linear regressions were also carried out to investigate whether gender or age was a predictor of FMS proficiency. The results presented will help to identify weaknesses in skills at the behavioural component level and will enable researchers and practitioners to address low levels of motor skill proficiency among CwID.
