Effects of plyometric and mixed-methods power training on ball velocity and kinematic parameters of instep kick after muscle fatigue in amateur futsal players

Abstract

The purpose of this study was to compare the effects of plyometric training and mixed-methods power training on the ball velocity and kinematic parameters of the instep kick after muscle fatigue in university futsal players. The study recruited 42 futsal players with an average age of 20.2 years, weight of 66.04 kg, and height of 172.7 cm. The subjects were divided into three groups comprising a control group (regular futsal training), a plyometric training group, and a mixed-methods training group. The training program was conducted for 8 consecutive weeks, with two training sessions per week. The researchers measured ball and ankle velocities, as well as hip and knee angular velocities, before the training program, after 8 weeks of training, and after inducing muscle fatigue. Collected data were analyzed using multivariate analysis of variance (MANOVA). The results showed that after the 8-week training program, both the plyometric training group and the mixed-methods training group showed an increase in mean ball and ankle velocities, as well as hip and knee angular velocities. However, there was no significant difference between the plyometric and mixed-methods training groups. Both training groups exhibited significantly higher values compared to the control group (p < .05). Similarly, the study found no significant differences between the plyometric training group and the mixed-methods training group in these variables after inducing muscle fatigue. However, both training groups had significantly higher values compared to the control group (p < .05). In summary, the study suggests that both plyometric training and mixed-methods power training can improve the ball velocity and kinematic parameters of the instep kick in foot athletes after muscle fatigue. The findings of this study have implications for training programs aimed at enhancing the performance of futsal players.
