The Relationship of Dorsiflexion Angle with Leg Volume, Balance, Speed, and Change of Direction Performance in Amateur Soccer Players

The aim of this study is to examine the relationship between dorsiflexion angles, leg volume, dynamic balance, speed performance, and change of direction performances depending on agility in athletes aged 14–15 who were raised in the infrastructure of various sports clubs and exposed to various training loads during the basic training period. 76 male football players who play football in the amateur league participated in our research at the Cizre Hamit Özalp Stadium, which is under the Cizre Youth and Sports District Services Directorate. Height, weight, body mass index, leg volume, 30 meter speed, Y-balance test, and Illinois test were applied to the performance of changing the direction of the athletes participating in the research. The SPSS package program was used for the analysis of the data obtained in the research. The Kolmogorov-Smirnov test was performed to determine whether the data obtained in the study showed a normal distribution. Spearman Rank Differences the correlation test, which is one of the non-parametric tests, was used to reveal whether there is a relationship between the right and left region measurement values of the athletes participating in the research. In the research findings, the relationship among dorsiflexion and muscle volume (r=0.301, p0.01), (r=0.427, p0.01), dorsiflexion and dynamic balance anterior (r=0.497, p0.01), posterolateral (r=0.331), p0.01), posteromedial (r=0.324, p0.01), muscle volume and dynamic balance anterior (r=0.390, p0.01), posteromedial (r=0.305, p0.01), posteromedial (r=0.365, p0.01) and balance anterior (r=-0.493, p0.01), posterolateral (r=-0.382, p0.01), posteromedial and deflection (r=-0.336, p=.01) performances were examined. As a result of the research, it has been determined that the muscle volume of the athletes with good dorsiflexion angles is also good, the dynamic balance performance of the athletes with good dorsiflexion angles is also good, the dynamic balance performance of the athletes with good calf volumes is also good, and the direction change performance of the athletes with good speed performance is also good.Keywords: Change of Direction, Dorsiflexion, Football, Range of Motion, Speed
