Lack of physical activity is a global public health problem causing not only morbidity and premature mortality, but it is also a major economic burden worldwide. One of the cornerstones of a physically active lifestyle is Motor Competence (MC). MC is a complex biocultural attribute and therefore, its study requires a multi-sectoral, multi-, inter- and transdisciplinary approach. MC is a growing area of research, especially in children and adolescents due to its positive association with a plethora of health and developmental outcomes. Many questions, however, remain to be answered in this field of research, with regard to: (i) Health and Developmental-related Associations of MC; (ii) Assessment of MC; (iii) Prevalence and Trends of MC; (iv) Correlates and Determinants of MC; (v) MC Interventions, and (vi) Translating MC Research into Practice and Policy. This paper presents a narrative review of the literature, summarizing current knowledge, identifying key research gaps and presenting questions for future investigation on MC in children and adolescents. This is a collaborative effort from the International Motor Competence Network (IMCNetwork) a network of academics and researchers aiming to promote international collaborative research and knowledge translation in the expansive field of MC. The knowledge and deliverables generated by addressing and answering the aforementioned research questions on MC presented in this review have the potential to shape the ways in which researchers and practitioners promote MC and physical activity in children and adolescents across the world.

Results of the Test of Gross Motor Development-2 (TGMD-2) consistently show acceptable validity and reliability for children/adolescents who are sighted and those who have visual impairments. Results of the Test of Gross Motor Development-3 (TGMD-3) are often valid and reliable for children who are sighted, but its psychometric properties are unknown for children with visual impairments. Participants (N = 66; M = 12.93, SD = 2.40) with visual impairments completed the TGMD-2 and TGMD-3. The TGMD-3 results from this sample revealed high internal consistency (ω = .89-.95), strong interrater reliability (ICC = .91-.92), convergence with the TGMD-2 (r = .96), and good model fit, χ(63) = 80.10, p = .072, χ/df ratio = 1.27, RMSEA = .06, CFI = .97. Researchers and practitioners can use the TGMD-3 to assess the motor skill performance for children/adolescents with visual impairments and most likely produce results that are valid and reliable.

Introduction: Children with CHARGE syndrome often show delays in balance and motor skills due to multisensory impairments. Research also suggests that children with CHARGE syndrome have fewer opportunities to engage in physical activity. However, little research has examined the relationship among all of these variables. Thus, the purpose of this study was to examine the relationship between balance, motor skills, and physical activity. Methods: Participants consisted of 37 children with CHARGE syndrome aged 3–16 years who could walk independently. Parents of each child with CHARGE syndrome completed a demographics questionnaire and the Physical Activity Questionnaire for Children or Adolescents. Their child completed the Mini-BEST balance test and five motor skills (run, jump, slide, kick, and throw) from the Test of Gross Motor Development II. Results: Results indicate that anticipatory control had significant positive correlations with all five motor skills, sensory orientation with three motor skills, and reactive postural control and dynamic gait with two motor skills. Running was the only variable that had a significant positive correlation with physical activity. Discussion: The findings indicate that balance, especially anticipatory control, plays an important role in fundamental motor skills of children with CHARGE syndrome. There is also a strong connection between physical activity and running competence for this population; however, since this is based on a correlational analysis, the direction of the relationship is unclear. Implications for practitioners: Physical education teachers should work with students with CHARGE syndrome on increasing balance and motor skill performance to give them the competence and confidence to engage in physical activity. Moreover, parents can help by engaging in physical activity with their child at an early age and seeking out additional physical activity opportunities for their child outside of the physical education and school setting.

Youth with visual impairments are more likely to be overweight than peers without visual impairments and often struggle with their locomotor skills. Locomotor development can combat unhealthy body weight statuses by supporting physical activity behaviors. There are no longitudinal investigations concerning the locomotor skill and body mass index (BMI) developmental trajectories of youth with visual impairments. The purpose of this study was to examine the 3-year developmental trajectory of the locomotor skills and BMI of youth with visual impairments including differential effects of self-reported gender and degree of vision. Participants (N = 34, Mage = 11.75 years, 47% female) showed severely delayed and arrested locomotor development with increases in BMI across 3 years regardless of self-reported gender or degree of vision. Participants failed to breech a proficiency barrier of motor competence to combat against increases in BMI across time. Additional longitudinal inquiries are needed.
