Abstract

The purpose of this study was to compare the effect of six weeks of strength and plyometric exercises on some of the kinematic parameters of the lower extremities in the impact on female football players aged 20 to 25 years. 30 female soccer players were divided into 3 groups: strength training, plyometric and control group with mean (10 persons, age 23.69 ± 2.39, height 163.66 ± 6.45, mass 61.15 ± 5.53) / 61, BMI: 24/51 ± 4/72). During the 6-week period, the players completed strength training protocols of 3 sessions and plyometric exercises 2 sessions per week and each session for 35 minutes, and the control group went to normal football practice. Each of the groups performed 5 hits in the pre-test and post-test. The data were filtered through a marker on the anatomical landmarks of the joints and subjected to low-pass filtering of low frequency 8-Hz cut-offs and recorded by a 240-Hz camera and analyzed with the software Skew Spector 2.3.1. The findings were analyzed by one-way ANOVA and Tukey's post hoc test. The results showed that strength and plyometric training on the kinematic parameters of the lower limb in the impact on the foot of female football players included: ball speed, angular velocity of the knee and thigh in the impact increase and a significant effect (P <0.05), as well as There was no significant effect on the hip, knee, ankle joint angle and angular velocity of the ankle joint (P> 0.05). The findings show that 6-week strength and plyometric exercises can significantly improve the speed parameters of the ball, the angular velocity of the knee joint and the angular velocity of the hip in the impact performance on the foot of female soccer players. Therefore, a strength training and plyometric training period for women's football is recommended.
