Introduction: Athletic groin pain (AGP) is one of the most common injuries among soccer players (Mansourizadeh et al., 2019). This study aimed to determine whether AGP changes the rate of force development (RFD) during a cutting maneuver in soccer players.
Methods:Twenty-eight soccer players (14 healthy, 14 with AGP) who took part in the second division league participated in the current study. The RFD related to the peak of force was evaluated during cross-cutting maneuvers via force plate with a 1000 Hz sampling rate. The subjects did these maneuvers 3-times with a 1-minute rest between trials (Shirzad Araghi et al., 2021). MATLAB and ORIGIN Pro software version 2021 were used to filter and process the force plate data. The data were processed using SPSS version 25. The Shapiro-Wilk test was used to check the normality distribution of data. An independent t-test was used to compare the results between healthy and AGP groups. The data were analyzed at a significance level of 0.05.
Results: The results indicated that AGP group in comparison with healthy one has significant higher RFD in medial-lateral direction (p=0.031). There were no significant differences in the anterior-posterior and vertical directions.
Conclusion:According to the result of this study, it seems that pain changes the RFD characteristic which put the athletes at the risk of further injuries. Due to the fact that body tissues are viscoelastic, their loading response is time-dependent; damage decreased at lower loads. In other words, at a lower load, a certain force is applied to the tissue for a longer period of time and the probability of tissue damage is reduced. It seems that the increase in RFD of the medial-lateral direction in the groin pain group increases the risk of the ankle lateral ligament injuries due to the consequent supination torque (Naserpour et al., 2020).
