Confiabilidade das variáveis dinâmicas mensuradas no Campusboard em escaladores esportivos

Abstract

The Campusboard is built in wood with holds placed vertically equipment where climbers supporting hands, and without the help of the lower limbs moving the body mass on the vertical axis. This equipment has been empirically associated with improved performance in sport climbing. Although widely used, there is lack of studies that investigate the reasons for these supposed improvements in performance as a result of the use of Campusboard. The aim of this study was to examine the reliability of dynamic variables measured in Campusboard in sport climbers. Data collection was performed in Moquiwa climbing gym in the city of Belo Horizonte, Minas Gerais. The sample consisted of 22 male sport climbers, aged (31,7 ± 6.1 years), body mass (69,7 ± 7,2) kg , height (176,0 ± 7,4) centimeters and without musculoskeletal upper limb injury in the last 6 months. The volunteers had a minimum of three years experience in sport climbing and already use the Campusboard in your training routine more than a year. The volunteers underwent two exercises called without countermovement and with countermovement; conducted over two days with an interval of 48 hours by a single evaluator. For each exercise five maximum runs with one minute of interval were performed. To measure the dynamic variables, two load cells were adapted in Campusboard. The reliability estimated for total maximum force CCI(2,1) 0,91; IC95% 0,8440,957 and of total momentum CCI(2,1) 0,90; IC95% 0,8280,952, indicated good reliability. The values estimated by the standard error of measurement of total maximum force 38,78 N IC95% ± 76,0 N and total momentum 11,92 N·s IC95%± 23,3 N·s were reliable. It was concluded that dynamic variables measured in Campusboard in sport climbers are reliable.
