Relationships between motor performance and body composition of school adolescents

Abstract

Introduction:Motor coordination is a result of interactions between many body systems, producing accurate and balanced kinetic actions. The evaluation of motor performance levels in children and teenagers may conserve and improve health and life qualities. Body composition may interfere considerably in motor coordination, particularly in overweight and obese conditions. Objective: To analyse the relationships between motor performance and body composition in children. Methods:Motor coordination was evaluated through the Körperkoordinations test für Kinder (KTK test), considering the motor quotient (MQ) and body composition using the body fat percentage (BF%) and body mass index (BMI).Results: BMI (38% and 36%) and BF% (28% and 22%), from boys and girls respectively, demonstrated that body composition is above the recommended. Girls presented MQ values lower than those observed in boys (p < 0.001). The groups with BFPs below the recommended value showed higher values of MQ than the normal group (p<0.05) and than children above the recommended ideal (p < 0.05). A reverse correlation was observed between MQ with BF% (r = -0.432) or BMI (r = -0.254). Conclusion:There are relationships between body composition and motor coordination in teenagers between 11 and 14 years old, related or not to gender and age. Why was this study done?This study was part of the master's dissertation of Prof. Giliard Mores in the Graduate Program in Physical Education at UFMT (Federal University of Mato Grosso). The theme was the result of the author's observation, as an active teacher of the State Basic Education Network, of disinterest in the practice of physical activities, increase of obesity and decrease in the motor capacity of students in the last decade. What did the researchers do and find?Using KTK (Körperkoordinationstest für Kinder), the evaluation of body mass index and body fat percentage, in 105 students, the aim was to investigate the relationship between motor performance and body composition in schoolchildren. Through this study, according to the tests applied, there was a high incidence of students with performance deficits to perform motor tasks, elevated rates of overweight and obesity, and a strong relationship between the increase in adiposity levels and a decrease in motor performance in the study population. What do these findings mean?They mean the need for greater care with the factors that trigger obesity, especially sedentary lifestyle, in children and adolescents, since they are related to the level of motor performance, which may reflect in the practice of physical activity and the health of these individuals at the moment current and adult life.

Association Between Motor Competence and Body Mass Index in Children Aged 10-13

“…Previously, similar findings were observed for non-athletic but healthyweight children. 20,24 On the other hand, various former examinations reported relatively higher values for the athletic population. 32,33 In their study, for instance, Vandorpe et al found 133.7 (±4.3) for elite female gymnast.…”

“…Previous research into gender differences is equivocal. [23][24][25][26]31 For example, Lopes et al examined the KTK performances of children aged 6-14 and noted the superiority of boys across all ages. 23 Notwithstanding, in line with the findings of the present study, Söğüt reported no significant gender effect in children between the ages of 6-14.…”

“…Some studies indicated that boys outperform girls in MC. 23,24 On the contrary, some others asserted comparable results. 25,26 Given the aforementioned evidence, more research is needed to gain greater insight into these interactions and differences.…”

Perfil motor de adolescentes do ensino fundamental de Macapá, estado do Amapá

“…A esse respeito, a Organização Mundial da Saúde -OMS (2016) alerta sobre a prevalência de disfunções motoras, também conhecidas por dispraxias, estimada entre 5 e 6% da população mundial e apresentadas pela Classificação Internacional de Doenças (CID-11) como 'Transtorno do Desenvolvimento da Coordenação Motora (ORGANIZAÇÃO, 2022). No Brasil, estudos evidenciam a preocupação acerca desta temática em crianças e adolescentes, onde o perfil motor (PM) identificado tem sido abaixo do esperado e a falta de vivências motoras agrava ainda mais essa realidade (GONÇALVES et al, 2021;MORES et al, 2019;RE et al, 2018;LUZ et al, 2018).…”

Comparative Study of Student Leadership Attitudes and Discipline Attitudes

“…These students participated in activities based on their interest in joining the organization to develop their talents and hoped to gain more knowledge and experience and more friends (Mandey & Sahangggamu, 2014) [15]. Students who participate in school organization activities should not only be involved in activities because organizing requires seriousness and activeness from students so that students can actually learn democratic in organizing (Susanty & Baskoro, 2013), (Moraes et al, 2019) [16,17]. With the involvement of students in school organization activities are expected to provide significant benefits that produce students who are characteristic and leadership spirit such as courageous to lead, dare to make decisions, dare to express opinions, be willing to accept criticism, have a chivalrous attitude, advice, open, honest, responsible, respect opinions, maintain and appreciate togetherness, trust, fairness, discipline, and so forth (Sari et al, 2012) (Syahrial, Asrial, Husni Sabil, 2020) [18,19].…”
