Brief 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.

Outcome Measures

Primary Outcomes (6)

• 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

All children received a series of 90-minute sessions 3 times a week for 8 weeks of after-school physical training. Each session began with a warm-up (20 min), three or four tasks related to the skill to be developed (aerobic training, resistance training, other activities designed to improve motor skills and balance, stretching and flexibility activities and core strength and posture exercises; 60 min) and a cool-down (10 min). Children were divided into six groups, with the number of children in each group ranging from eight to twelve.
