Level of motor performance and its relationship with physical fitness in adolescents

This research was characterized as a quantitative cross-sectional descriptive. During the motor development process, a series of physical and mechanical changes occur, where the factors of physical growth, maturation, development of physical fitness, physical activity, age and experience are interrelated. The general objective of this study was to study the different effects of physical fitness on the motor performance of adolescents aged 13 to 16 years in the city of Itaituba / Pará. Methodology developed was with the n = sample of 102 students of both genders aged between 13 and 16 years old from the city of Itaituba / PA. All guardians signed the ICF and were released by the doctor for the tests, the instruments used were MABC-2, 6/9 walk / run, TG Lohman protocol, Wells Bank, Medicinibol Pitch, Sargent Jump Test, Impulse Test Horizontal, Anthropometric Scale. The statistics used were descriptive and inferential through the SPSS program that evaluated the relationship and or association of the results. Results: when compared between genders, boys showed an index of 85.4% and girls 72.2% within normal limits. For the Physical Fitness variable, only the values of the Medicinibol Throw, Horizontal Impulse and Flexibility tests showed above-average rates. When compared between genders, boys did not outperform girls in the abdominal, horizontal push and fat percentage test. In the analysis of the maturational state, performed through the Peak Growth Speed test, girls reached this state at around 12.9 years of age, while boys at 14.6 years of age. In the analysis of motor performance, only 38.9% of the girls are in the green zone, presenting 40.7% with indicative of BDD, in boys, 50% are in the green zone and only 18.8% have indicative of BDD. In the association of motor performance between age, physical fitness and nutritional status, the results point to significance only for the association between motor performance and an item of physical fitness, flexibility. We conclude that the process of acquisition of motor skills emerges due to environmental and socioeconomic influences, of course, without forgetting, mainly, the interaction between genotype and phenotype on motor performance. Nowadays we observe a huge decline in the provision of motor opportunities for children and adolescents, generating less stimulus and, therefore, few motor experiences.
