Relação entre a progressão do escore do functional movement screen e lesão em atletas futebol / Relationship between progression of functional movement screen test and injury in athletes of football

O futebol é uma modalidade de grande exigência física com movimentos de potência e velocidade com mudança de direção. Devido à alta intensidade, ocorre uma maior predisposição às lesões. O Functional Movement Screen (FMS) é um modelo de avaliação para identificar assimetrias e desequilíbrios musculoesqueléticos. O objetivo deste trabalho foi comparar os efeitos de do is m eses de pré-temporada na progressão do escore do teste FMS e sua relação com as lesões ao longo da competição. Participaram deste estudo 28 atletas profissionais de futebol, com idade média de 25,1 ± 6,5. Foi realizado o FMS antes e após a pré-temporada e durante o período competitivo foi verificada a ocorrência de lesões. Houve uma melhora (p<0,01) dos escores do FMS da avaliação pré (15,61 ± 1,39) para a avaliação pós pré-temporada (17,29 ± 1,24) entre todo o elenco, porém, quando considerado o tamanho do efeito, os atletas que não se lesionaram tiveram um efeito maior na progressão do escore (d=1,17) do que os que se lesionaram (d=0,35). Conclui-se que os atletas que não se lesionaram durante a competição, foram os que mais progrediram no FMS durante a pré-temporada, sendo, provavelmente, a progressão do escore do s atletas mais interessante do que o atendimento ao ponto de corte sugerido pela literatura...(AU)

Football is a modality that demands high physical fitness, with intense movements and rapid direction changing. Due to the high intensity demanded, athletes are more susceptible t o in juries. The Functional Movement Screen (FMS) test it is a method to evaluate asymmetries and muscle im balance. The objective was to compared the effects of two months of preseason, on the score of the FMS t est and their relationship with the injuries resulting from the competitive period. Participated o f th is study 28 professional football players (25.1 ± 6.5 years). FMS was performed before and after the p reseason and during the competitive period the occurrence of injuries was verified. There was a significant improvement of the FMS score after the preseason (p<0.01) for the all athletes. When considering the size effect, athletes who were not injured during the competitive period had a greater effect (d=1.17) than those who injured (d=0.35). The athletes who progressed the most during the evaluation were the athletes who were exempted from injury during the competitive period. Perhaps the progression of the athlete's score was more interesting than the attendance to the cut-off point suggested by the literature...(AU)

The validity of Keiser-M3 stationary bicycle with standard ergometer for physiological measurements associated with maximum effort

Abstract Aim: This study aims to investigate the concordance between two cycle ergometers for variables measured in the test of maximum incremental effort. Methods: This correlation study enrolled 15 inactive women (19,2 ± 4,0 years old). At random, the participants performed two maximal effort incremental tests (MEIT), using cycle ergometers (Keiser-M3 and Ergo-167) on different days with a minimum interval of 72 hours. The test had stages of two minutes, and two-step increments were carried out at the end of each stage. Lactate concentration ([LAC]), and rated perceived exertion (RPE) were collected, in addition to monitoring oxygen uptake (VO2) and heart rate (HR). The Paired t-test was carried out to compare physiologic variables, Lin's test was used for correlation, and Bland Altman was used to measuring concordances among variables. Results: The correlations between physiologic parameters were considered strong for HR on the anaerobic threshold (Keiser M3 = 146 ± 14 bpm; Ergo-167 = 149 ± 9 bpm; r = 0.762), greater blood lactate value (Keiser M3 = 9,97 ± 2,51 mmol/L; Ergo-167 = 9.71 ± 2.56 mmol/L; r = 0.820), VO2max (Keiser M3 = 38,37 ± 6,97 mL/kg/min; Ergo-167 = 36.06 ± 8.4 mL/kg/min; r = 0,806) and HRmax (Keiser M3 = 186 ± 53 bpm; Ergo-167 = 188 ± 11 bpm; r = 0.716). Conclusion: The results show the feasibility of using the cycle ergometer Keiser, model M3, to perform the maximal effort incremental test, whereas there was high concordance in the physiologic responses in both ergometers for inactive women.

Psychophysiological profile and prediction equations for technical performance of football players / Perfil psicofisiológico e equações preditivas de desempenho técnico em jogadores de futebol / Perfil psicofisiológico y ecuaciones predictivas de rendimiento técnico de jugadores de fútbol

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.

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.

Resumen El objetivo fue correlacionar habilidades técnicas específicas (STS) con evaluaciones psicofisiológicas. Las STS de 15 jugadores de fútbol se recogieron mediante técnica de scouting de dos partidos. Salto contramovimiento, concentración sanguínea de creatina-cinasa, variabilidad de la frecuencia cardíaca y las puntuaciones de DALDA y POMS se obtuvieron 24 h después de ambos partidos. Se elaboraron ecuaciones predictivas y POMS y DALDA se ajustaron a los modelos con alto coeficiente de determinación (r2) para finalización (r2 = 0,85), interceptación (r2 = 0,73), pase correcto (r2 = 0,32), quite de balón (r2 = 0,69) y pérdida de balón (r2 = 0,35). Las variables psicológicas identificadas a través de POMS y DALDA han mostrado gran influencia en las STS.
