SUMMARY:

Motor development (DM) can be defined as the continuous changes in motor behavior throughout life, it is multicausal and inseparable from genetic and environmental factors. It can be divided into phases, among them, the fundamental movement phase in which the fundamental motor skills (HMFs) of stability, locomotion and manipulation are developed. The HMFs are the basis of the motor repertoire that leads in sequences to specialized movements and that, therefore, will be used to participate efficiently in organized and unorganized physical activities throughout life, and therefore, increases the chances of those who develop them. proficiently, to have a physically active lifestyle preventing the emergence of chronic non-communicable diseases. The objective of this research was to investigate the impact of the period of social isolation due to the Covid-19 pandemic on the development of HMFs of schoolchildren aged 7 to 10 years. This is a longitudinal study that observed the performance of students in HMFs. The study procedures were carried out in two stages, the first being before the beginning of social isolation due to the pandemic, in March 2020 (T1) and the second after the easing of social isolation and the return to face-toface classes in the educational system of Minas Gerais, in August 2021 (T2). The students were weighed and measured, the parents/guardians responded to an adapted anamnesis to identify the socioeconomic class of the family and inform the daily routine of the participants in T1 and T2, considering the social restrictions of isolation. To test the motor performance, the Test of Gross Motor Development – 3 (TGMD-3) was used. This test assesses 13 fundamental motor skills divided into the locomotion and ball skills subtests. The first study, which evaluated the DM and HMFs of schoolchildren in general and compared by sex, showed DM below what was expected for their age, especially in ball skills. Emphasis on the girls who were even worse than the boys, more specifically on the skills of bouncing and kicking the ball. It was concluded that the stimuli received by children throughout their lives, especially regarding manipulation skills, including in physical education classes, were not enough to develop the children's fundamental motor skills. Stratifying the participants, only those who were 10 years old were evaluated in terms of TGMD – 3 and routine in T1, as it is expected that at this age they would be proficient in DM as well as in HMFs. The results showed DM below the expected for the age. Most played at home (84.2%), had more than two hours a day to do whatever they wanted (73.7%) and did not participate in guided activity outside the context of physical education classes (68.4%) . They then showed better performance on the locomotion subtest (47.4% on average) than on the ball skills subtest (5.3% on average) (Chi-square X2 = 10.5; p = 0.04) . Therefore, it is possible to assume that the opportunities to perform tasks throughout life were more focused on the performance of locomotion activities than ball skills. However, due to low global motor performance, it is possible to infer that physical education classes alone are not enough for good performance in fundamental motor skills, both for boys and girls. The second study evaluated the impact of the period of social isolation on the development of schoolchildren's HMFs. According to the theory of human development, considering the maturational aspects, no type of worsening in performance from T1 to T2 was expected. And more than 60% of the students remained stable or got worse in the locomotion subtest, and 71.4 presented the same results in the ball skills subtest. Most participants increased the time spent with technological devices such as cell phones, computers and tablets, considered sedentary activities, also increased the time they slept and began to play more at home, which was statistically significant and has a negative association with the performance of children. fundamental motor skills. The proportion of participants who started to perform housework increased significantly, and this had a positive association with improved performance of locomotion skills. However, motor development is multicausal and inseparable from environmental factors, so an isolated fact does not explain the phenomenon as a whole. Therefore, it is concluded that the factors 10 associated with changes in the school's routine, together, influenced the development of HMFs, since this development is multicausal and is inextricably modified by genetic and environmental factors. And the findings reinforce this theory, that of dynamical systems.
