2D analysis

Purpose: The Purpose of this study was to investigate ball velocity of instep and inside foot kicks of university level soccer players. Method: The participants sample consisted twenty university soccer players from Fiji National University, Fiji. All participants have minimum of four years playing experience. The participants delivered instep and inside foot kicks using the right leg. Participants wore a complete soccer kit. Two cameras were used for this study. The cameras intersected each other perpendicularly on sagittal and frontal plans. Motion Analysis Tools (MAT) software was used to determine the ball velocity and IBM SPSS 30 was used to calculate pair t-test involving two tail tests to determine the significant difference of the ball velocity of university soccer players. Results: The results of the study indicate that the mean velocity of instep soccer kick is higher than the mean velocity of the inside foot soccer kicks. A significant difference also exists at the .05 level between the instep and the inside foot soccer kicks of the participants. Conclusion: It can be concluded that the inside foot kick resulted in a lower ball velocity than the instep kick on the part of the university level players.

The kicking skills in soccer have a complex motor movement with assisted by of whole body segments
and joints. The purpose of this research was to determine and enlighten the kinematical determinants of soccer
instep  and  inside  foot  kick  at  impact  phase.  Twenty  male  soccer  players  were  recruited  for  this  study  from Lautoka campus of Fiji National University, Fiji. Participants delivered instep and inside of the foot kick with their dominant (right) foot. Each player executed three trails of each kicks with a stationary ball.  Two video
cameras  were  used  for  this  study.  The  sampling  rates  of  the  cameras  were  60  frames  per  second.  For
identification purposes, a number was given for each trail. The best trail kicks were identified and edited for
analysis.  The identified  trails  were played  with the  Kinovea  Software  to  get the  angular  movement  of lower extremity  joints.  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 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.  The  result  also  revealed  that  hip  joint  showed  significant difference with ankle and knee joint angle. Whereas there is no significant mean difference found between ankle and knee joint angle for instep kicks.  For the inside foot kick, the result showed that there are significant mean differences  among  ankle,  knee,  and  the  hipjoint  angle  at  impact  phase.  The  knowledge  of  details  regarding kinematic  parameters  of  impact  phase  would  be  helpful  to  the  coach  and  the  player  in  obtaining  better performances.
