Research On The Influence Of Situational Exercise Training On Children’s Intelligence And Motor Development

Objective: This research probes into the influence of situational exercise training on intellectual and motor development of full-term and preterm infants aged below 18 months,providing a basis for child health care and early intervention.Methods: A total of 220 infants who were born at DALIAN WOMEN AND CHILDREN’S Medical Group from July 2020 to July 2021 were researched.Among them,112 infants were classified into the full-term group and 108 infants were classified into the preterm group based on the gestational age.The full-term group was further divided into full-term group with exercise training consisting of 55 infants and the fullterm group without exercise training consisting of 57 infants;and the pre-term group was further divided into the pre-term group with exercise training and the pre-term group without exercise training.Both groups were subject to health guidance and management in accordance with the National Child Health Care Standards(Trial Implementation),the Eight Technical Specifications for Child Health Care,and the Standards for Health Care for Preterm Infants(2017).The infants in exercise training group received individualized situational exercise training in addition to the same guidance and management for those in the conventional guidance group.CDCC scale was used for to measure the mental development index(MDI)and psychomotive development index(PDI)at the age of 6 months,12 months and 18 months respectively for full-term infants or at the corrected age of 6 months,12 months and 18 months respectively for preterm infants.The intellectual and motor development of all infants were evaluated.Then,the intellectual and motor development at the age of 6 months,12 months and 18 months were compared between the full-term group with exercise training and full-term group with conventional guidance,between the preterm group with exercise training and preterm group with conventional guidance,between preterm group with exercise training and full-term group with conventional guidance,and between preterm group with excise training and full-term group with exercise training.Results: At the age of 6 months,there was different interaction effect between the preterm group and the full-term group.The MDI and PDI varied significantly between the two preterm groups with higher MDI and PDI in preterm group with exercise training,and there was statistical significance(P<0.05);the MDI did not vary significantly between the preterm group with exercise training and the full-term group with conventional guidance or between the preterm group with exercise training and the fullterm group with exercise training,and there was no statistical significance(P>0.05)between the two full-term groups;the PDI varied significantly between the two preterm groups,between the preterm group with exercise training and full-term group with conventional guidance and between preterm group with exercise training and full-term group with exercise training,with statistical significance(P<0.05),but there was no statistical significance(P>0.05)between the two full-term groups;At the age of 12 months,there was different interaction effect among the four groups in terms of MDI.The MDI varied significantly between the two preterm groups with statistical significance(P<0.05),where the MDI in preterm group with exercise training was higher than that in the preterm group with conventional guidance.However,there was no such significant difference between the two preterm groups,or between the preterm group with exercise training and full-term group with conventional guidance,or between the preterm group with exercise training and full-term group with exercise training,without statistical significance(P > 0.05);there was no interaction effect between the preterm groups and the full-term groups in terms of PDI;At the age of 18 months,there was different interaction effect among the four groups in terms of MDI.The MDI varied significantly between the two preterm groups with statistical significance(P<0.05)but not between the preterm group with exercise training and full-term group with conventional guidance,or between the preterm group with exercise training and full-term group with exercise training,or between the two fullterm groups,and there was not statistical significance(P>0.05);there was no interaction effect among the four groups in terms of PDI.The PDI did not vary significantly between the preterm group with exercise training and the full-term group with conventional guidance,and there was no statistical significance(P>0.05).Conclusion: After situational exercise training,the intellectual and motor development of preterm infants at corrected ages of 6 months can be significantly improved;their intellectual development is significantly improved compared with those with conventional guidance at the corrected ages of 12 and 18 months;the intellectual and motor development of preterm infants at corrected age of 18 months reach the same level of full-term infants with conventional guidance at the age of 18 months.
