scholarly journals MOTOR AND INTELLECTUAL DEVELOPMENT IN CHILDREN: A REVIEW

Author(s):  
Milan Čoh

The aim of this narrative review article is to present the effects of physical activity on the motor and cognitive development of children. Early childhood is one of the most critical periods in a child's physical and intellectual development. As much as seventy percent of the brain's connections develop during the pre-school years, these connections form the basis and framework for the child's later abilities and characteristics. A physically stimulating and varied environment undoubtedly has a significant impact on the mental functions of children. The brain is designed to learn and solve problems, initially simple, later complex. The earliest challenges that the brain needs to solve are related to movement. Children solve these problems spontaneously, intuitively, and in an unstructured manner. Later, with more organized movements, children acquire various motor skills, abilities, and sensory experiences, thereby gaining a new understanding of themselves and their surroundings. These insights and experiences will equip the child for the challenges and problems they will face later in life. Children enter into social interactions and group dynamics through movement and acquire a sense of autonomy and independence. A stimulating and varied motor environment undoubtedly has a significant impact on children's intellectual function and, thus, on the development of their potential abilities.

Children with a visual impairment are less active than their sighted peers. Yet, they are born with the potential to match their sighted peers’ motor skill competency and levels of physical fitness. Environmental barriers are one of the main causes of inequities. This article provides insight on these issues, drawing upon a physical activity intervention called ‘First Steps’, a British Blind Sport initiative that aimed to get more children with a visual impairment more active. Physical activity packs were delivered to 53 children, aged 5–15 years, with a visual impairment. Of these participants, 62% had additional impairments or medical conditions. A mixed-methods approach was used to gather participants’ experiences of physical activity prior to receiving this pack and canvas opinion on how the pack changed their activity levels. The findings revealed inequitable experiences of physical activity. The First Steps pack made considerable progress in developing children’s physical activity levels. Participants’ motor skills, social interactions, and confidence improved. Organisations working with this population might look to adopt a similar concept. Recommendations for those wishing to do so are provided.

The article studies the connection between mental and intellectual development and regular physical exercise. The subject is considered topical due to the widespread fallacious judgements of sport and studies of its influence on various aspects of our life. The primary purpose of this article is to determine the effect of regular exercise on the brain and establish whether it is a positive one. The research methods used in this study included description, observation, literature review and summary. The article is based on the results of theoretical studies of other researchers and the author’s own observations. In the course of study, a positive effect of regular exercise on intellectual and mental activity was established. The authors can therefore conclude that physical activity does not only benefit the body, but also the brain by improving memory, concentration and reaction, helps transport oxygen minimizes the risk of anxiety, depression and stress, and develops the nervous system.

Cellular structures provide the physical foundation for the functionality of the nervous system, and their developmental trajectory can be influenced by the characteristics of the external environment that an organism interacts with. Historical and recent works have determined that sensory experiences, particularly during developmental critical periods, are crucial for information processing in the brain, which in turn profoundly influence neuronal and non-neuronal cortical structures that subsequently impact the animals’ behavioral and cognitive outputs. In this review, we focus on how altering sensory experience influences normal/healthy development of the central nervous system, particularly focusing on the cerebral cortex using the rodent whisker-to-barrel system as an illustrative model. A better understanding of structural plasticity, encompassing multiple aspects such as neuronal, glial, and extra-cellular domains, provides a more integrative view allowing for a deeper appreciation of how all aspects of the brain work together as a whole.

The purpose of this study was to investigate the effects of classroom-based Brain Breaks® Physical Activity Solution in Southeast Asia Singaporean primary school students and their attitude towards physical activity (PA) over a ten-week intervention. A total of 113 participants (8–11 years old) were randomly assigned to either an experimental (EG) or a control group (CG), with six classes to each group; the Brain Breaks® group (EG: six classes) and the Control group (CG: six classes). All EG members participated in a Brain Breaks® video intervention (three–five min) during academic classes and the CG continued their lessons as per normal. The student’s attitudes towards PA in both research conditions were evaluated using the self–reported Attitudes toward Physical Activity Scale (APAS), applied before and after intervention. The effects of the intervention on APAS scores were analysed using a mixed model analysis of variance with Time as within-subject and Group as between-subject factors. The analysis revealed evidence in support of the positive effect of classroom video interventions such as Brain Breaks® on student’s attitudes toward benefits, importance, learning, self-efficacy, fun, fitness, and trying to do their personal best in PA. The Brain Breaks® intervention provided a positive significant impact on students in Singapore. This study also revealed that interactive technology tools implemented into the school curriculum benefit students in terms of health and education.

In mammals, the reproductive function is controlled by the hypothalamic-pituitary-gonadal axis. During development, mechanisms mediated by gonadal steroids exert an imprinting at the hypothalamic-pituitary level, by establishing sexual differences in the circuits that control male and female reproduction. In rodents, the testicular production of androgens increases drastically during the fetal/neonatal stage. This process is essential for the masculinization of the reproductive tract, genitals and brain. The conversion of androgens to estrogens in the brain is crucial for the male sexual differentiation and behavior. Conversely, feminization of the brain occurs in the absence of high levels of gonadal steroids during the perinatal period in females. Potential genetic contribution to the differentiation of brain cells through direct effects of genes located on sex chromosomes is also relevant. In this review, we will focus on the phenotypic alterations that occur on the hypothalamic-pituitary-gonadal axis of transgenic mice with persistently elevated expression of the human chorionic gonadotropin hormone (hCG). Excess of endogenously synthesized gonadal steroids due to a constant hCG stimulation is able to disrupt the developmental programming of the hypothalamic-pituitary axis in both transgenic males and females. Locally produced estrogens by the hypothalamic aromatase might play a key role in the phenotype of these mice. The “four core genotypes” mouse model demonstrated a potential influence of sex chromosome genes in brain masculinization before critical periods of sex differentiation. Thus, hormonal and genetic factors interact to regulate the local production of the neurosteroids necessary for the programming of the male and female reproductive function.
