Introdução: os objetivos deste estudo foram: i) identificar os padrões motores associados à execução técnica de manobras no surf; ii) as características físicas inerentes à reprodução desses padrões motores; e, iii) analisar essas características físicas segundo o nível técnico dos surfistas. Metodologia e Resultados: partindo de uma análise qualitativa, tendo como base a divisão da técnica por fases, fez-se uma triangulação de dados, com revisão de literatura e observação, os movimentos de rotação, flexão e flexão lateral do tronco bem como de flexão e extensão dos membros inferiores foram identificados como padrões motores base (PMB) na execução de manobras no surf. Segundo os PMB e investigações precedentes, foram selecionados testes para quantificar, em dois grupos de atletas, elite (n=37) e regional (n=15), características físicas inerentes à reprodução dos PMB e execução das manobras. Atletas de elite apresentaram valores mais elevados em todos os testes, exceto na capacidade de extensão da coxa, foram encontradas diferenças estatisticamente significativas no Squat e Countermovement Jump, Seated Trunk Rotation Test e Y-Balance Test (p<0.05). Conclusões: a capacidade de flexão do tronco, coxa e tornozelo, a potência dos membros inferiores e a capacidade de equilíbrio dinâmico são características físicas integrantes da técnica de surf e parecem contribuir para uma melhor performance na modalidade. A capacidade de potência dos membros inferiores, de rotação lateral do tronco e de equilíbrio dinâmico, para além da relação com a componente técnica, são, em atletas de surf jovens, diferenciadoras segundo o nível técnico dos surfistas.
Introduction: The present study aims to: i) identify the motor patterns related to the technical execution of surf manoeuvres; ii) identify the physical characteristics associated with the execution of those patterns, and, iii) analyse those physical characteristics according to surfers' technical level. Methodology and Results: starting with a qualitative analysis, based on the triangulation of observation data, literature review and the break down of the technique into phases, rotation, flexion and lateral flexion of the trunk as well as lower limbs flexion and extension were identified as Basic Motor Patterns (BMP) in the execution of surf manoeuvres. According those BMP and prior research, specific tests were selected to analyse and quantify, the physical characteristics related to surf manoeuvres execution in two separated athlete groups, elite (n=37) and regional (n=15). Elite athletes scored higher in every test, except hip extension ability. Statistical significant differences were observed regarding Squat and Countermovement jumps, Seated Trunk Rotation Test and Y-Balance Test (p<0.05). Conclusions: Trunk, hip and ankle flexion, lower body power and dynamic balance ability are physical characteristics intrinsic to surfing technique, and, appear to contribute for a better performance in surfing. Lower body power, lateral trunk rotation and dynamic balance, beyond this relation with surfing technique are also differentiating, in young Portuguese surfers, according to their technical level.
