Investigation of non-contact injuries prediction by parameters related to internal and external loads in a Premier League team

Training loads are one of the important indicators for improving performance and injury prevention, so the present study aimed to investigate the prediction of non-contact injuries by parameters related to internal and external loads in a Premier League team during a season.In this quasi-experimental study ۲۳ players of the Foulad Mobarakeh Sepahan football team participated in the present study. The internal load was collected through Borg’s questionnaire. A GPS device was used to record the data. The parameters of acute load, chronic load, internal load, acute to chronic load ratio, monotony, strain, and the number of non-contact injuries were calculated and collected. Spearman and Pearson’s statistical tests were used to examine the relationship between variables and multiple linear regression was used to evaluate the predictability of injury through load-related parameters.The results showed that acute load, monotony, and strain were directly and moderately related to non-contact injuries. However, these parameters do not have the ability to predict these injuries. No significant relationship was observed between the other parameters and the number of non-contact injuries.Internal and external training loads have many derivatives that can be used to improve performance and prevent non-contact injuries. The results of this study showed that strain, monotony, and acute load can be better predictors of injury. It seems that paying attention to these parameters can help coaches to reduce injury. However, more data is needed to conclusively prove this claim and more considerations are needed in this regard.
