Resumo
Este trabalho teve por objetivo determinar e analisar as razões obtidas pela força de reação vertical e pelo impulso, gerados pelo exercício de hidroginástica Lagosta I, praticado fora d'água, e na profundidade de água na altura do processo xifóide em relação ao peso corporal das amostras, e também determinar e analisar as freqüências médias do exercício. O outro objetivo proposto foi determinar e analisar as razões obtidas pela força de reação vertical e pelo impulso, para este mesmo tipo de exercício, adicionando-se pesos de 5,0 N e 10 N, assim como determinar e analisar as freqüências médias. A amostra foi composta por dez (10) indivíduos, sendo cinco (05) do sexo masculino e cinco (05) do sexo feminino, com idade média de (22 2,13) anos, todos alunos de Educação Física e não praticantes de hidroginástica. O exercício Lagosta I foi escolhido por ser o mais utilizado nas aulas de hidroginástica no Brasil, de acordo com Morais (1998). O tempo de execução do exercício foi de 1 minuto, e o tempo de recuperação entre uma execução e outra foi de 3 minutos. Este experimento foi realizado no Laboratório de Biomecânica da FEG, onde o tanque de hidroginástica e a plataforma de força foram projetados e construídos. Através de softwares específicos, Catman 3.1 e do Excel, foram determinadas e analisadas as três (03) variáveis biomecânicas: a força de reação vertical; o impulso e a freqüência, provenientes do exercício Lagosta I, praticado no solo e na água, e com influência do peso. As forças médias de reação vertical registraram valores entre 2 a 3 vezes o peso corporal, enquanto na água, estes valores ficaram próximos do peso corporal no solo. As freqüências médias no solo ficaram entre 2,22 Hz e 2,81 Hz, e na água entre 1,36 Hz e 2,19 Hz. Os impulsos médios no solo foram superiores aos impulsos médios obtidos na água....
The aim of this paper was to determine and analyse the ratios got from the vertical reaction power and from the impulse, produced by the hydrogymnastics exercise Lobster I, performed out of water and in the water, around the process xifóide, regarding the sample physical weight, and also to determine and analyse the average frequencies the exercise. Another aim was to determine and analyse the ratios got from the vertical reaction power and from the impulse, to the same kind of exercise, addition weight the 5,0 N and 10 N, as well as to determine and analyse the average frequency. The sample was formed by tem (10) people, five (5) men and five (5) women. The average age was (22 l 2,13) years old. All of them were Physical Education (P.E.) students and didn't practice hydrogymnastics. The Lobster I exercise was chosen because it was the most used in the hydrogymnastic classes, in Brazil, in agreement with Morais (1998). The exercise performance time was one minute and the resting time between the perfoemances was three minutes. This experiment was carried out in the Biomechanic Laboratory, at FEG, where the hidrogymnastics tank and the power plataform were drawn and built. Through specific softwares, Catman 3.1 and Excel, the three (3) biomechanical variables were determined and analysed: the vertical reaction power; the impulse and the frequency, which came from the Lobster I exercise, performed on the ground and in the water, with the influence of the water weight. The average powers of the vertical reaction registered values between two or three times the body weight, while, in the water, those values got near the body weight on the ground. The average frequencies on the ground were between 2,22 Hz and 2,81 Hz and, in the water they were between 1,36 Hz and 2,19 Hz. The average impulses on the ground were higher than the average impulses in the water ...(Complete abstract, click electronic address below).
