Resumo
O surf é um desporto de participação em massa em todo o mundo, apreciado por ambos os sexos e de uma ampla idade demográfica. Contudo, apesar da sua audiência global, existem poucos dados relacionados às características fisiológicas e de desempenho dos praticantes desta modalidade. Para se poder melhorar a performance competitiva dos praticantes de surf e ao mesmo tempo tentar prevenir as lesões, principalmente as não traumáticas, é necessário primeiro uma caracterização do tipo de esforços, das características físicas dos praticantes. Desta forma, o objetivo desse trabalho foi medir a força isocinética dos músculos rotadores internos e externos do ombro, dos extensores e flexores do joelho e o equilíbrio em praticantes de surf do estado do Ceará. 15 praticantes recreacionais experientes de surf com uma idade compreendida entre os 18 e 37 anos, com uma massa corporal de 71,66±5,69 kg, uma estatura média de 173,80±4,16 cm e com tempo de prática de 13,27±6,38 anos, viram o seu equilíbrio corporal avaliado por uma Biodex Balance System, e força isocinética avaliada por uma Biodex System 4 Pro. Nos dados recolhidos no presente estudo, foi verificado que o surf praticado recreacionalmente parece não causar desequilíbrios significativos entre a musculatura extensora e flexora dos joelhos. Igualmente, parece que não acentua dentro dos valores normais o desequilíbrio entre a musculatura rotadora interna e externa do ombro. O equilíbrio parece, igualmente, não ser potenciado com a prática do surf.
Surfing is a mass participation sport around the world enjoyed by both sexes and a broad demographic age. However, despite its global audience, there are few data related to the physiological and performance characteristics of the practitioners of this modality. In order to be able to improve the competitive performance of surfers and at the same time to try to prevent injuries, especially nontraumatic ones. Primarily it is necessary a characterization of the type of efforts of the physical characteristics of the practitioners. Thus, the objective of this study was to measure the isokinetic strength of the internal and external rotator muscles of the shoulder, the extensors and flexors of the knee and the balance of surfers in the state of Ceará. 15 experienced recreational surfers aged between 18 and 37 years with a body mass of 71.66 ± 5.69 kg, a mean height of 173.80 ± 4.16 cm and a time of practice of 13, 27 ± 6.38 years. Body balance assessed by a Biodex Balance System, and isokinetic strength evaluated by a Biodex System 4 Pro. In the data collected in the present study, it was verified that recreationally practiced surfing does not seem to cause significant imbalances between extensor and flexor muscles of the knees. Likewise, Surf does not appear to accentuate within the normal values the imbalance between the internal and external rotator muscles of the shoulder. The balance also seems not to be enhanced by surfing.
