O tema do presente estudo é a motivação à prática regular de atividades físicas de atletas de Basquetebol de 13 a 16 anos. Trata-se de uma investigação com uma abordagem focada na perspectiva da Pedagogia do Treinamento Desportivo. Parte-se do pressuposto de que é importante para o treinador/professor conhecer os principais fatores que motivam os atletas para que o plano de atividades seja conduzido da melhor forma possível. O objetivo central da pesquisa foi explorar os níveis de seis dimensões motivacionais associadas à prática regular de atividades físicas (Controle de estresse, Saúde, Sociabilidade, Competitividade, Estética e Prazer), que melhor descrevem os atletas de Basquetebol da faixa etária de 13 a 16 anos. Todos participam de Competições Institucionalizadas (Campeonatos Escolares, Campeonatos Inter-Clubes, JERGS, dentre outros). Mais especificamente, o estudo procurou descrever os níveis destas seis dimensões motivacionais das seguintes variáveis: Sexo; Categorias (“até 14 anos” e “até 16 anos”); Tempo de participação em competições (“1º ano” e “mais de 1 ano”). Foi verificado, também, se houve diferenças estatisticamente significativas entre as dimensões motivacionais e as variáveis controladas. Para tanto, foi aplicado o Inventário de Motivação à Prática Regular de Atividades Físicas (IMPRAF-54; BALBINOTTI e BARBOSA, 2006). As respostas aos itens do IMPRAF-54 são dadas conforme uma escala de tipo Likert, bidirecional graduada em 5 pontos, partindo de “isto me motiva pouquíssimo” (1) a “isto me motiva muitíssimo” (5). O IMPRAF-54 foi aplicado em 441 atletas de Basquetebol infanto-juvenis de 13 e 16 anos, vinculados as Instituições esportivas dos estados do Rio Grande do Sul e Santa Catarina. Constatou-se que a dimensão que mais motiva os atletas de Basquetebol infantojuvenis é o Prazer (1º); seguida, respectivamente, pelas dimensões Competitividade e a Saúde (estatisticamente indissociáveis) (2º); Sociabilidade (3º), Estética (4º); e, por último, Controle de Estresse (5º). Com relação às variáveis controladas, percebe-se que a dimensão Sociabilidade é a que mais motiva os atletas de basquetebol que estão no seu “1º ano” de competição, quando comparados àqueles que estão a “mais de 1 ano” competindo. Outro resultado dessa pesquisa aponta que os atletas de Basquetebol da categoria “até 14 anos” são mais motivados pela Competitividade do que os atletas da categoria (“até 16 anos”). Ao compararmos as diferenças entre o sexo “masculino e feminino”, as dimensões Competitividade e Estética se destacam como aquelas que mais motivam os atletas do sexo masculino. Portanto, os resultados indicam que os atletas de Basquetebol infanto-juvenis de 13 a 16 anos praticam o esporte por motivos intrínsecos. Recomenda-se que outros estudos sejam realizados para que se possa aprofundar ainda mais os conhecimentos sobre esta temática. / The present study has as its subject the motivation regarding the regular practice of sports and physical activities in Basketball athletes from 13 to 16 years old. It is an inquiry focused in the perspective of the pedagogy of the sports training. It is an assumption that it is important for the coach or teacher to know the main factors that motivate the athletes having the plan of activities prepared in the best possible way. The main reason of this study was to explore six dimensions of motivation associated to the practice of sports and regular physical activities (Stress Control, Health, Sociability, Competitiveness, Esthetics And Pleasure), that best describe the athletes that practice Basketball with ages ranging from 13 to 16 years old. All athletes participate to institutionalized competitions (school competitions, inter-clubs competitions, JERGS, among others). More specifically, this study tries to describe the levels of these six motivational dimensions of the following variables: gender; categories (“up to 14” and “up to 16 years of age”); time of competition (“one year” and “more than one year”). It was also verified if there were any significant statistical differences between the motivational dimensions and the controllable variables. In order to obtain all this answers, it was applied an inventory called “Inventario de Motivação à Pratica Regular de Atividades Físicas” (IMPRAF-54; BALBINOTTI e BARBOSA, 2006). The IMPRAF-54 is a test that rates the answers in a Likert scale form of 5 points (1 – It’s not very motivating to 5 – It’s very motivating) verifying in nominal values, the dimensions that motivate most Basketball players to the practice of sports and physical activities on a regular basis. The IMPRAF–54, surveyed a sample of 441 young Basketball players of both genders, ages between 13 and 16 years old, tied by States of Rio Grande do Sul and Santa Catarina, Brazil. It was verified that the dimensions that most motivates young Basketball players to practice regularly is Pleasure; followed to Competitiveness and Health (indivisible statistically); Sociability; Esthetics; and, finally, Stress Control. In the relation to controlled variable it was observed that the Sociability was the dimension that most motivates the young Basketball athletes when they are in their first year as competitors. Another result that this study shows is that the athletes of the category “up to 14” are significantly more motivated by Competitiveness than the “up to 16”. When we compare the differences between “males and females”, the dimensions Competitiveness and Esthetics were prominence significantly more motivating to males athletes. Therefore, the results indicate that young Basketball athletes from 13 to 16 years old practice sports by intrinsic motives. It is recommended that further studies be conducted in order to deepen the knowledge on this topic.

Basketball is one of the most injury-risk team sports. Taking into consideration high frequency of knee joint injuries in both young and professional basketball-players and especially issues of overloads of locomotor apparatus in adult basketball, it is crucially important to develop and propose an effective prevention programs to avoid acute injuries and traumas of knee joints. The proposed study was focused on the development of special training prescriptions and recommendations for coaches and physical trainers aimed to implement prevention methods in the training process. The study was conducted in the Ural Federal University Sports Technologies Research Lab. Twenty young athletes born in 2002 from basketball youth sport schools (Yekaterinburg, Russia) were recruited for the study. The significant interrelations between functional state, oxygen transport and utilization systems and power of working muscles were established for the first time. A novel prevention program of knee joint injuries was introduced, effectiveness of which was proved during the study. / Баскетбол входит в пятерку самых травмоопасных командных, контактных видов спорта. Актуальность исследования обусловлена высокой частотой травматизма коленного сустава, как у молодых, так и у профессиональных баскетболистов. В особенности это грозит игрокам молодежных составов, так как при переходе в профессиональную команду растёт объем интенсивности нагрузки на опорно-двигательный аппарат и зачастую отсутствуют программы профилактики травматизма. Данная работа посвящена разработке рекомендаций по построению тренировочного процесса и внедрение в него программы профилактики травматизма для снижения степени риска повреждения коленного сустава. Исследование проводилось на базе лаборатории «Технологии восстановления и отбора в спорте» ЦКП ФГАОУ ВО УрФУ имени первого Президента России Б.Н. Ельцина. В исследовании приняли участие 20 юных спортсменов 2002 года рождения, воспитанники детско-юношеских спортивных школ (г. Екатеринбург). Впервые была установлена связь между общим функциональным состоянием организма спортсмена, системой транспорта и утилизации кислорода работающими мышцами и силой мышц нижних конечностей. Была разработана и внедрена в тренировочный процесс программа профилактики травматизма коленного сустава, эффективность которой была доказана в ходе исследования.
