Summary:
This study focuses on the effects of physical activity in schools on the cognitive function and physical fitness of children with and without developmental coordination disorder (DCD). Methods: 58 children with DCD participated in an 8-week exercise program. Children's standing broad jump (SBJ), 50m dash, 50m\*8 shuttle run, mental rotation and executive functions were assessed before and after training. A mixed-design analysis of variance (ANOVA) was conducted separately for each performance variable.

Primary Outcome Measures: Reaction time (RT) of mental rotation tasks, The experiment involved simultaneously presenting children with two pictures of "giraffes". The image on the left was fixed as the target, and the image on the right showed angle or mirror differences. The angular disparities were 0°, 60°, 120° or 180°. Through rotation, the children were asked to determine, as quickly and accurately as possible, whether the two images were identical., 8 weeks|Reaction time (RT) of modified Stroop task, The computerized modified Stroop task includes the following two conditions: a naming (non-execution) and execution condition. In the naming condition, the screen will display a colored "XXX" and the children need to press the key corresponding to the color. In the execution condition, the stimulus will show a distracting-colored word, similar to the classic Stroop, showing Chinese characters in either blue or red; in this test, the children need to press the key corresponding to the color of the word, rather than the meaning of the Chinese character. When the color of the word is consistent with its meaning, the condition is congruent; when the color of the word is inconsistent with its meaning, it is the condition is incongruent., 8 weeks|Standing broad jump, The SBJ test, which is completed on a flat surface, is used to evaluate the explosive strength of the lower limbs., 8 weeks|50m sprint, The 50m sprint test requires students to start in a standing position and complete a 50m sprint with all their strength. The test is conducted twice, and the fastest result is recorded., 8 weeks|50m*8 shuttle run, children are required to run back and forth between two points as quickly as possible., 8 weeks|Safety and Tolerability, There were no safety and adverse events, 8 weeks
Secondary Outcome Measures: Height, Height was measured to the nearest 0.1 cm (Shanghe SH-200G, China), 8 weeks|Weight, weight was measured to the nearest 0.1 kg using a portable stadiometer (Shanghe SH-200G, China)., 8 weeks
Other Outcome Measures: Safety and Tolerability, Number of participants with adverse events, From enrollment until at least 12 weeks after completion of study treatment
