RESUMO
Resumo O objetivo foi correlacionar variáveis psicofisiológicas com desempenho técnico específico (STS). As STS foram coletadas durante dois jogos amistosos através de scout técnico. Salto contramovimento, concentração sanguínea de creatina quinase ([CK]), variabilidade da frequência cardíaca (HRV) e os escores de POMS e DALDA também foram acessados. Equações preditivas foram testadas e os escores de POMS e DALDA formaram modelos de regressão com significância estatística e coeficiente de determinação (r2) expressivo para as STS de finalização (r2 = 0,85), interceptação (r2 = 0,73), passe certo (r2 = 0,32), roubada de bola (r2 = 0,69) e perda de posse de bola (r2 = 0,35). Variáveis psicológicas foram capazes de predizer o desempenho técnico em STS coletadas em scout de partidas de futebol.Abstract The objective was to correlate specific technical skills (STS) with the psychophysiological performance. STS from 15 soccer athletes were collected by technical scouting of two matches. Countermovement jump, blood concentration of creatine kinase ([CK]), heart rate variability (HRV) and the scores of DALDA and POMS were also obtained 24 h after both matches. Predictive equations were elaborated, and POMS and DALDA scores were the only variables which fits the models for STS with high coefficient of determination (r2) for finalization (r2 = 0.85), interception (r2 = 0.73), pass right (r2 = 0.32), tackling (r2 = 0.69) and loss of ball (r2 = 0.35). The psychological variables identified through POMS and DALDA have shown greater influence on the STS.
