Abstract(s)
Um dos maiores desafios que os jogadores profissionais de futebol enfrentam ao longo
das suas carreiras são as lesões desportivas. Níveis excessivos ou insuficientes de carga
de trabalho podem levar a fadiga crónica e aumentar o risco de lesões musculares. O
objetivo deste estudo foi analisar a relação entre a ocorrência de lesões musculares e as
variáveis locomotoras em termos de volume e intensidade durante a pré-época e a
primeira fase competitiva, considerando duas épocas desportivas diferentes dentro de
uma mesma equipa. Participaram neste estudo 53 jogadores de futebol masculino (25,0 ±
4,3 anos; 180,5 ± 5,8 cm; 76,2 ± 6,9 kg) de um clube profissional da Primeira Liga
Portuguesa. Os resultados mostraram uma interação significativa entre as duas épocas e
os dois momentos da época para a distância total [.65, F (1, 51) = 28.1, p < .001], corrida
em alta velocidade [.91, F (1, 51) = 5.92, p = .026], acelerações [.75, F (1, 51) = 16.8, p
< .001], desacelerações [.87, F (1, 51) = 7.8, p = .007], metros percorridos por minuto
[.43, F (1, 51) = 67.7, p < .001], metros máximos percorridos por minuto [.49, F (1, 51)
= 52.4, p < .001] e tempo total de todas as sessões semanais de treino [.74, F (1, 51) =
17.9, p < .001]. Os nossos resultados indicam que quanto maior o volume e a intensidade
dos níveis de carga de trabalho, menor é a probabilidade de os jogadores sofrerem lesões
musculares nas duas primeiras fases de uma época desportiva. Investigações futuras
poderão beneficiar da inclusão de mais variáveis e da integração de outros clubes no
estudo.
One of the major challenges that professional football players must overcome during their careers is sports injuries. Excessive or insufficient workload levels can lead to chronic fatigue and increase muscle injury risk. The aim of this study was to analyze the relationship between the occurrence of muscle injuries and locomotor variables in terms of volume and intensity during the pre-season and first competitive phase, considering two different sporting seasons within one team. 53 male football players (25.0 4.3 years old; 180.5 5.8 cm; 76.2 6.9 kg) from a professional football club of the First Portuguese League participated in this study. Our results showed a significant interaction between the two seasons and the two moments of the season in total distance [.65, F (1, 51) = 28.1, p <.001], high-speed running [.91, F (1, 51) = 5.92, p =.026], accelerations [.75, F (1, 51) = 16.8, p < .001], decelerations [.87, F (1, 51) = 7.8, p = .007], meters covered per minute [.43, F (1, 51) = 67.7, p < .001], maximum meters covered per minute [.49, F (1, 51) = 52.4, p < .001], and total time of weekly training sessions [.74, F (1, 51) = 17.9, p < .001]. Our findings showed that the larger the volume and intensity of workload levels are, the less likely the players are to suffer muscle injuries in the first two stages of a sporting season. Future research could benefit from considering more variables and integrating other clubs.
