Purpose: This study aimed (1) to evaluate the test–retest reliability of a new agility test among children and (2) to determine the physical performance and anthropometric variables that may influence agility performance in this population. Methods: For aim 1, participants (n = 34) completed the Ladder Agility Test (LAT) twice, with a 2-week interval between the first and second test occasions. For aim 2, participants (n = 125) were assessed on the LAT as well as other measures thought to be necessary for agility such as motor coordination, explosive power of the lower extremity, dynamic balance, age, and body mass index. Results: Intraclass correlation coefficient of the LAT total score was.94 (95% confidence interval,.88–.97). Cronbach alpha of.85 was found between the 4 test items. An R
2 of.466 was found to represent the explained variance of the LAT total score by the predicting variables. Dynamic balance (2-legged side jumps) (P <.001), motor coordination (P <.01), and age (P <.06) were found to be the major predictors of the LAT total score. Conclusions: This study shows that the LAT is a reliable and valid field-based test that can be used to evaluate agility performance in children. Factors such as dynamic balance, motor coordination, and age may influence agility performance. [ABSTRACT FROM AUTHOR]- Published

Background: Assessment of anaerobic capacity in children with Developmental Coordination Disorder (DCD) is essential for treatment planning. However, available field-based measures have no established validity and reliability in this population. Purpose: To examine the psychometric properties of selected field-based anaerobic capacity tests in children with and without DCD. Methods: School-aged children (6–16 years) with and without DCD participated in the study. The children completed the shuttle run sub-item of the Bruninks-Oseretsky test of motor proficiency-second edition, the 10 × 5 m sprint tests (straight and slalom) and the muscle power sprint test (MPST). Results: The shuttle run test item of the Bruninks-Oseretsky test of motor proficiency-second edition and 10 × 5 m sprint tests possess good construct validity and test–retest reliability in children with DCD. The 10 × 5 m sprint test-slalom was found to be the most responsive test among children with DCD. However, the MPST was less reliable in children with DCD compared to their typically developing peers, leading to a very large Smallest Detectable Difference. Conclusions: The findings suggest that the selected anaerobic capacity measures have sound psychometric properties among children with DCD with the exception of the MPST. Clinicians working on children with DCD could use these tests in their practice, especially in situations where logistical resources are limited. Field-based anaerobic capacity tests are suitable measures for assessing anaerobic capacity in children with Developmental Coordination Disorder, particularly in situations where laboratory assessments are not feasible. The shuttle run test item of the Bruninks-Oseretsky test of motor proficiency-second edition and the 10 × 5 sprint tests (straight and slalom) have good construct validity in this population. The 10 × 5 sprint test (slalom) is the most sensitive anaerobic capacity test among children with Developmental Coordination Disorder. [ABSTRACT FROM AUTHOR]

Purpose: Children with Developmental Coordination Disorder (DCD) are known to have poor physical fitness. However, differentiating homogenous subgroups of DCD using fitness performance has not yet been established. Therefore the purpose of this study was to identify subtypes in children with and without DCD using measures of physical fitness.Method: Children (aged 6-10 years, n = 217) constituted the sample for this study. They were assessed on 1) aerobic fitness (20m Shuttle Run test), 2) anaerobic fitness (Muscle Power Sprint Test), 3) isometric muscle strength (handheld dynamometry) 4) functional upper and lower body strength (Functional Strength Measurement) and 5) motor coordination [Movement Assessment Battery for Children-2nd edition (MABC-2) test]. The Ward method was used to identify the various clusters.Results: Five subtypes emerged in the entire sample. In the typically developing (TD) children mainly 2 subtypes (number 5 and 2) were found containing 89% of the TD children (n = 55), with the largest group demonstrating above average performance on all measures (cluster 5). Children in subtype 2 had just above average motor coordination and good aerobic fitness but lower muscle strength. Subtypes 1, 3 and 4 were clearly "DCD" clusters, however they showed difference in fitness performance. Subtype 1 contained children with DCD who showed poor performance on all fitness outcomes (n = 45). Children with DCD in subtype 3 had poor aerobic but average strength and anaerobic fitness (n = 48). Subtype 4 contained children with DCD (n = 45) who had good muscle strength and anaerobic fitness. Of these, 36% were at risk of DCD while 24% had definite motor coordination problems.Conclusion: Our findings indicate that children with and without DCD demonstrate heterogeneous physical fitness profiles. The majority of the children (66%) with DCD belonged to subtypes with lower fitness performance. Further studies are needed to confirm these findings in other samples of DCD children.

Objective: Transfer of motor skills is the ultimate goal of motor training in rehabilitation practice. In children with Developmental Coordination Disorder (DCD), very little is known about how skills are transferred from training situations to real life contexts. In this study we examined the influence of two types of practice on transfer of motor skills acquired in a virtual reality (VR) environment. Method: One hundred and eleven children with DCD and their typically developing (TD) peers, aged 6–10 years (M = 8.0 SD = 1.0) were randomly assigned to either variable (n = 56) or repetitive practice (n = 55). Participants in the repetitive practice played the same exergame (ski slalom) twice weekly for 20 minutes, over a period of 5 weeks, while those in the variable group played 10 different games. Motor skills such as balance tasks (hopping), running and agility tasks, ball skills and functional activities were evaluated before and after 5 weeks of training. Results: ANOVA repeated measures indicated that both DCD and TD children demonstrated transfer effects to real life skills with identical and non-identical elements at exactly the same rate, irrespective of the type of practice they were assigned to. Conclusion: Based on these findings, we conclude that motor skills acquired in the VR environment, transfers to real world contexts in similar proportions for both TD and DCD children. The type of practice adopted does not seem to influence children’s ability to transfer skills acquired in an exergame to life situations but the number of identical elements does.

Background: Evidence on anaerobic power and sprinting performance of children with Developmental Coordination Disorder (DCD) is limited.Aims: The primary aim of this study was to investigate if the Children's Repetitive and Intermittent Sprinting Performance (CRISP) test could induce fatigue among participants. Secondly, the study examined the construct validity of the test in children with probable DCD (p-DCD) and typically developing (TD) peers.Methods and Procedures: The study was carried out in two phases. In phase 1, we compared performance of 25 children (7-12 years) on the CRISP test to their performance on the Muscle Power Sprint test (MPST). For phase 2, forty-six (n = 46) participants with p-DCD were matched with TD children (n = 46) on age, weight and sex. Anaerobic performance of participants was assessed using the CRISP test, 10 × 5 m sprints straight and slalom tests, side jumps, stepping on platform task and the ladder agility test.Outcomes and Results: Phase 1: The increase in running time on the CRISP test was greater than on the MPST, indicating that the CRISP test was more fatiguing than the MPST. Phase 2: Children with p-DCD had poorer anaerobic capacity (muscle power, muscle endurance) compared to their TD peers. However, fatigue was comparable between the two groups. The differences in performance between p-DCD and TD children were found to be greater for tests with more agility elements.Conclusions and Implications: The findings showed that CRISP test could induce fatigue in children. The CRISP test was also found to have positive construct (i.e. known-group) validity. The differences in muscle power and endurance between children with p-DCD and TD peers tend to widen when assessments are performed with tests having high agility components.
