Adequate development of Fundamental Motor Skills (FMS) at a young age benefit holistic development and positive health outcomes. This study determined age and sex developmental differences in the state and the relationships between process and product assessments of four fundamental-motor skills (FMS) in five to eight-year-olds. An availability sample of 636 children; 291 boys, 345 girls, mean age of 6.8 ± 0.97 years in the North West Province of South Africa participated in the study. Spearman rank order correlations analyzed relationships between assessments, while sex and age differences were examined using independent t-testing and one-way ANOVA. Age showed significant developmental trajectories in all FMS. Older children were found to be more at risk for not learning FMS to mastery, while unique developmental patterns were also established compared to international trends. Strong to moderate significant practical associations (p < 0.05) emerged between process and product assessments in catching (r = 0.79), jumping (r = 0.40) running (r = −0.33) and kicking (r = 0.20), while also confirming that the strength of the associations varies depending upon the skill type. Associations strengthened with increasing age, were higher in girls in all FMS, while associations between behavioral criteria in all FMS also differed between FMS and sexes. These strong associations, need to be taken into consideration during the development of FMS towards obtaining full mastery.

Background: Developmental coordination disorder (DCD) affects motor skills and consequently has an impact on the performance in daily living activities of learners with this impairment.Aim: The aim of this study was to determine the prevalence of possible DCD in Grade 1 (Gr. 1) learners in a low socio-economic environment in Mangaung, South Africa.Setting: The study was conducted in the Mangaung Metro, Motheo District, Free State Province. Gr. 1 learners, 6–8 years old (n = 242), from a low socio-economic environment attending Quintile 1–3 schools were randomly selected for assessment.Methods: The Movement Assessment Battery for Children-2nd edition (MABC-2) was used to identify learners with possible DCD. Furthermore, results were compared with regard to gender.Results: Of the 242 learners, 9.9% were identified with possible DCD. With regard to gender, 10.5% of boys and 9.3% of girls showed signs of possible DCD. No significant difference (p = 0.9439) has been found between boys and girls.Conclusion: The prevalence of possible DCD among Gr. 1 learners in this setting was higher than that in previously reported studies in other low and high socio-economic environments of South Africa. Further research is required to establish the full extent of possible DCD within learners living in low socio-economic environments.

Background: Early identification of learners in low socio-economic environments with possible developmental coordination disorder (DCD) is important. Although various screening tools are available, it is unclear whether teachers can use the movement assessment battery for children - second edition checklist (MABC-2 checklist) to identify learners with possible DCD.Aim: To establish teachers’ ability to identify Grade 1 learners in low socio-economic environments with possible DCD.Setting: The study was conducted in the Mangaung Metro, Motheo District of the Free State Province, South Africa. Grade 1 learners aged 6–8 years (n = 200) from a low socio-economic environment attending quintile one to three schools were randomly selected for assessment. Twenty-nine teachers participated in the study.Methods: Kinderkineticists identified learners with possible DCD (displaying motor skills far below the child’s age) by means of the MABC-2 performance test. The teachers used the MABC-2 checklist to identify possible DCD. The convergent validity of the MABC-2 performance test and checklist was compared.Results: The convergent validity between the MABC-2 performance test and the MABC-2 checklist indicated a kappa (k) coefficient of 0.17, indicating a slight agreement between the performance test and the checklist. Overall, the specificity was 58% (105/180), and the sensitivity was 85% (17/20).Conclusion: Teachers could effectively identify learners with possible DCD. However, they demonstrated a low ability to identify learners without possible DCD when using the MABC-2 checklist. It is therefore recommended that the performance test should be used in conjunction with the checklist to obtain the most reliable results.
