![]() ![]() Analysis of variance designs with repeated measures indicated a significant increase in ammonia (P0.01). Three-dimensional data, ground reaction forces (GRFs) and segmental moments were measured during the kick while blood lactate and ammonia concentrations were monitored throughout the protocol. Ten male amateur soccer players performed maximal instep kicks prior to, in the middle and after the implementation of a 90 min intermittent exercise protocol. The purpose of this study was to examine the effects of fatigue on biomechanical indices of soccer kick performance. The knowledge of details regarding kinematic parameters of impact phase would be helpful to the coach and the player in obtaining better performances. For the inside foot kick, the result showed that there are significant mean differences among ankle, knee, and the hipjoint angle at impact phase. Whereas there is no significant mean difference found between ankle and knee joint angle for instep kicks. The result also revealed that hip joint showed significant difference with ankle and knee joint angle. The findings of the study have confirmed that the angle of ankle and hip joints are insignificant between instep and inside foot kick at impact phase, whereas the angle of the knee joint is differed significantly between instep and inside foot kick of university players. For statistical analysis IBM SPSS was used to determine descriptive analysis, analysis of variance and t-test to detect a mean difference between joints (Ankle, Knee, and Hip) of instep and inside of foot kicks. ![]() The identified trails were played with the Kinovea Software to get the angular movement of lower extremity joints. The best trail kicks were identified and edited for analysis. For identification purposes, a number was given for each trail. The sampling rates of the cameras were 60 frames per second. Two video cameras were used for this study. Each player executed three trails of each kicks with a stationary ball. Participants delivered instep and inside of the foot kick with their dominant (right) foot. Twenty male soccer players were recruited for this study from Lautoka campus of Fiji National University, Fiji. The purpose of this research was to determine and enlighten the kinematical determinants of soccer instep and inside foot kick at impact phase. The kicking skills in soccer have a complex motor movement with assisted by of whole body segments and joints. ![]()
