Effects of plyometric training in Colombian soccer players (17-18 years old) according to their position in the field of play

Abstract

Soccer as a sport demands a series of situations where explosive strength is determinant. The objective of the present research was to determine the effects generated on the explosive strength of the lower body when applying a training program based on the plyometric method, in soccer players between 17 and 18 years old of the Academia Iguarán Fútbol Club, according to their positioning within the field of play. The study included 32 players, grouped in control group (n:16) and experimental group (n:16), which were associated by position, central defenders (DC n=6), lateral defenders (DL n=6), midfielders (VOL n=12) and forwards (DEL n=8). The study had a quantitative approach, descriptive and quasi-experimental design. The statistical treatment was performed using the statistical software ® version 4.1.0. The results show that the jumping capacity reflects differences between positions, for the flyers there were significant differences (p=0.03) on the variables of flight time, jumping height and speed peaks, with the forwards being very close to these values. This may respond to the demands and/or specific requirements of the game positioning, mainly for the development of actions where strength is a protagonist. The application time of the plyometric program generates different adaptations at a muscular level, taking into account that the data obtained for the different positions showed that in some positions changes are evidenced on variables such as height and speed, while in others there are changes on strength and power.
