| Popis: | 107 Background and Objectives: Developmental Coordination Disorder (DCD) is characterized by impaired motor coordination that involve difficulty in fine motor and gross motor control and interfere with academic performance and activities of daily living. Previous studies showed that health-related physical fitness and exercise tolerance were poor in children with DCD, which may be attributed to spending less time in participating in physical activities due to their poor motor coordination and inferior motor competence. However, in Taiwan, subject to relevant Laws, children with DCD are not eligible for utilizing special educational resources and professional team services in school for their special needs. Studies indicated that after receiving the motor skill training for a few months, significant improvement in motor skills could be observed in children with DCD, such as balance and object manipulation. Likewise, children with DCD exhibited progress in aerobic and anaerobic cardiopulmonary fitness, muscle strength, and muscular endurance after a couple of months of fitness program. Nevertheless, there were some limitations in previous literature. Limited investigations examined the effectiveness of the health-related physical fitness program for children with DCD. Moreover, functional muscle strength, reflecting muscle strength required for daily lives, is rarely examined in previous studies. In addition, it is unclear whether the effectiveness of treatment can be preserved after cessation of intervention because follow-up studies are sparse. Furthermore, results of previous studies indicate that those studies targeting on motor skills training report greater improvement on motor skills while others addressing on physical fitness training illustrate more favorable performance on cardiopulmonary fitness. Because physical fitness encompasses overall aspects of health and is also in line with the needs of children with DCD, it might be better that program combines physical fitness and motor skill training. Hence, the purpose of this study was to investigate whether children with DCD would improve their motor skills, health-related physical fitness, and physical activity after receiving the 8-week health-related physical fitness and motor skill training program. In addition, we also explored whether the training effect would persist after 8-week follow-up. Methods: This study was a quasi-experimental with pretest-posttest single group design. Children with suspected DCD aged 6 to 11 years were recruited. The classification of children with suspect DCD was confirmed by a score of ≦15 percentile on MABC-2 assessment. Children with DCD received 8 weeks of physical fitness and motor skill intervention. All subjects were collected for their basic data before intervention and assessed for outcome measurements at pretest, posttest, and 8-week follow-up during the study period. The outcome measures included the Bruininks-Oseretsky Test of Motor Proficiency-2(BOT-2), Weight-Length Index(WLI), 6-minute walk test(6MWT), sit and reach, one-minute sit-ups, and physical activity assessed using Actigraph® GT3 triaxial accelerometers. Basic data were presented using the descriptive statistics. Repeat measure 1-way ANOVA was used to compare the difference of outcome data at pretest, posttest and follow-up. P value was set at 0.05 and was adjusted as 0.017 by the Bonferroni correction for post-hoc tests. All statistical analysis were performed using SPSS 24.0. Results: The results revealed that there were significant improvements in motor skills (manual coordination(p |
