Influence of Preschool Children's Fundamental Movement Skills, Physical Activity, and Physical Fitness on Executive Function: A Prospective Observation Study
2022年3月13日 更新者：Hong Kong Baptist University
Background: Early childhood is the most critical and rapid period of complete and healthy physical and cognitive development in human life. Executive function appears in early childhood and develops rapidly through complex coaction between environment and developmental processes. The preschool period is also characterized by a rapid growth in fundamental movement skills, physical activity and physical fitness. The scientific research on the relationship between fundamental movement skills, physical activity, physical fitness and executive function in preschoolers remains to be explored.
Objective: The purpose of this study was to examine the cross-sectional relationship between fundamental movement skills, physical activity, physical fitness and executive function in preschool children while controlling for potential confounding variables, examine the prospective influence (independent and interactive role) of preschooler's fundamental movement skills, physical activity and physical fitness on executive function, observe the preschoolers' fundamental movement skills, physical activity, physical fitness and executive function changes with age, and investigate gender and age differences in preschoolers' fundamental movement skills, physical activity, physical fitness and executive function.
Method: The proposed study consists of two phases, phase 1 is a cross-sectional study. Five hundred and five children aged 3-5 years will be recruited. The Test of Gross Motor Development Third Edition (TGMD-3) was used to assess children's fundamental movement skills. Preschool children's physical activity was monitored by accelerometer ActiGraph GT3X-BT. Physical fitness was tested using handgrip, 4*10m shuttle run, 20m shuttle run, 30s sit-ups, sit and reach, and balance beam. Executive function was tested by computer-based tasks including animal stroop, safari training and stop signal task. Phase 2 is a 12-month follow-up study. In the phase 2, all children enrolled in the baseline study will be followed up, the measurements and contents of the follow-up are the same as the baseline instrument.

Change of cardiorespiratory fitness
時間枠：through study completion, 12 months

A 20-meter shuttle run is used to assess cardiorespiratory fitness.
During the test, participants run back and forth on two running tracks 20 meters apart at an initial speed of 8.0km/h, followed by an increase of 0.5km/h per minute.
Using a compact disc (CD) to control the speed, which systematically increases during the test.
During the test, participants run back and forth, based on the timing of a beep from the CD recorder.
If the participant fails to pass the other end of the 20 meters distance before the beep (after two attempts), the test is terminated and the number of shuttle legs completed is recorded and converted to an estimate of aerobic capacity.
As we work with preschoolers, the track will be marked and the children will be led by an adult so they can master the pace of the run.

They hold the dynamometer, adjust the grip distance, grasp the dynamometer once with maximum strength, and the value is recorded.
The left and right hands are measured alternately for three times, and the maximum value is recorded.
To allow for proper rest, the interval between the three tests should be at least 15 seconds.

When participants hear the start command, they will move their feet to the finish line in turn.
The tester will give orders on the front side of the participant, start the stopwatch at the same time when the participant starts, and follow the participant to the finish line.
At the same time, the tester will pay attention to observe the movements of the participant to prevent accidents.
When either tiptoe of the participant crosses the finish line, the tester stops the clock immediately.
