Perfil fisiológico e cinemático de cadeirantes basquetebolistas durante um teste intermitente incremental

Abstract

Wheelchair Basketball (BCR) is a sport aimed at people with permanent disabilities in the lower limbs, presenting a functional classification system that allows the inclusion of various levels of injury, a factor that depends on performing physiological assessments and analyzes. and cinematic. The study aims to analyze the physiological and cinematic profile of basketball players in a wheelchair during the incremental intermittent physical test. The sample consisted of 10 male players aged (37.44 ± 7.32), body mass index (BMI) (24.99 ± 5.84), all with more than three years of gaming experience. Players perform the YoYo Test - IR1 incremental field test. Peak Oxygen Uptake (VO2peak), blood lactate concentration [La-] pre, immediately after and three minutes after the test, heart rate (HR), ventilatory thresholds (LV1 and LV2), cycle time, contact time, recovery time, elbow flexion, internal and external rotation of the shoulder and trunk flexion and extension, average speed and propulsive frequency were measured. The normality of the data was verified using the Shapiro-Wilk test (p < 0.05). Pearson's correlation between VO2peak, HR, LV1 and LV2 with the functional classification was performed. Comparison between moments based on LV1, LV2 and VO2peak was performed by ANOVA one-way repeated measures (parametric data) and the Friedman’s 2-way ANOVA test (non-parametric data). There were changes between the different intensities zones at all times of the physiological variables during the test (p = 0.001), except for [La-] immediately after the test (p = 0.899), with effect size (0.86, 0.86 and 0.60 respectively, p < 0.05). In the kinematic variables, there was a difference in recovery time (p = 0.003), flexion of the right elbow (p = 0.001), internal rotation of the right shoulder (p = 0.001) and trunk flexion (p = 0.001), with effect size (0.19, 0.31, 0.40 and 0.21 respectively, p < 0.05). There was a moderate correlation between HR, VO2peak, LV1 and LV2 measurements (r = 0.528 and 0.674, 0.62 and 0.67, p < 0.05) between the functional classification, respectively. There were kinematic changes in recovery time, elbow flexion, external shoulder rotation and trunk flexion, as well as movement compensation in the angular variables, as there was a difference between the moments only on one side of the upper limbs. An analysis of an incremental intermittent test in the field, besides being more feasible for the athlete (according to the situation closest to a game), presents greater feasibility to a prescription of individual training according to the legibility that the athlete presents and according to physiological and kinematic response.
