RESUMO
As exigências fisiológicas em desportos aquáticos têm vindo a ser estudadas a fim de possibilitar,
melhor e maior conhecimento das respostas orgânicas, por forma a auxiliar os atletas e
praticantes das diversas atividades, na sua preparação física. O objetivo deste estudo foi
identificar as exigências fisiológicas impostas pela modalidade de kitesurf.
Para tal, dez indivíduos de elite realizaram um teste máximo em passadeira e um teste em água
com percurso delineado, com a duração de 30 min e com uma velocidade de vento entre os 16-25 nós. O consumo de oxigênio (VO
2
) foi calculado a partir da frequência cardíaca (FC) registada
durante o teste em água usando a relação individual FC-VO2
determinada durante o teste
máximo de esforço. A média de valores da FC e o VO2
estimado representam, respetivamente,
80,31±3,19% da frequência cardíaca máxima e 67,64±5,00% de consumo máximo de oxigênio
para velocidades de bordo que variam de 16 e 25 nós.
Este estudo sobre Kitesurf sugere que a exigência energética é principalmente sustentada pelo
metabolismo aeróbio durante uma condição de vento moderado.
ABSTRACT The physiological demands of water sports have been studied so as to enable and improve the knowledge of organic responses to help prepare athletes and practitioners of different activities. The aim of this study was to identify the physiological demands of kite surf. To do so, ten individuals did a test on a treadmill and another test in the water with an outlined course, taking 30 minutes and with wind velocity between 16 and 25 knots. Oxygen consumption (VO 2 ) was calculated from heart frequency that was registered during the test in the water using the individual relation heart frequency –oxygen consumption. This was determined during the maximum stress test. The estimated average of heart frequency and oxygen consumption values represent 80,31±3,19% of maximum heart frequency and 67,64±5,00% of maximum oxygen consumption for onboard velocities that vary from 16 to 25 knots. This study about kite surf suggests that energy demand is mainly sustained by aerobic metabolism during moderate wind condition.
