The results thus obtained indicate that the Kinovea software is a valid and reliable tool that is able to measure accurately at distances up to 5 m from the object and at an angle range of 90°–45°. To evaluate Kinovea reliability and validity a multiple approach was applied involving the following analysis: -systematic error with a two-way ANOVA 2x4 -relative reliability with ICC and CV (95% confidence interval) -absolute reliability with Standard Error. For each export data item, 20 angles and 20 distance variables were calculated, with intra- and inter-observer reliability also analysed. Each frame was examined by three observers who each made two attempts. For this purpose, a figure with 29 points was designed (in AutoCAD) and 24 frames analysed. The main objective of this study was to determine the validity and reliability of the Kinovea software in obtaining angular and distance data at different perspectives of 90°, 75°, 60° and 45°. Although it has been validated as a tool with which to assess time-related variables, this is not yet the case regarding angular and distance variables. This low-cost technology has been used in sports sciences, as well as clinical field and research work.

Kinovea © is a free 2D motion analysis software that enables the establishment of kinematics parameters. For kinematic analysis, athletes were recorded as they passed through halfway (4550 m) at back straight on the 400 m track by using two standard digital HD camcorders (Nikon B700, 60Hz) mounted 90 angles on two rigid tripods 4 m away from the track inside & outside where reference volume was 5 m long and 1.5 m high. A recommendation can be formulated that the contribution of straddle foot placement during take-off can significantly increase the value of power measurement especially when the evaluation requires a complex movement structure with the division on the left and right legs, for example, sprint start from block.Clinical rehabilitation and sports performance analysis both require the objectification of movement. The contribution (EMG activation) made by the 6 muscles were almost the same during all phases for the 2 jumps however, some differences can be found, in either unilateral (single leg) or sums of both legs (bilateral) measurements. The take-off angles on the COM trajectory also showed differences (69.87 and 66.8°, respectively) between each other. The take-off velocity with 90° knee initial angle initiation of take-off was not different (1.18 and 1.17 m Average standing long jump performances with straddle foot placement were 13.58 cm (5.18%) above that from parallel feet placement.

Using kinematic and kinetic data, the knee joint angle, the trajectories of center of mass (COM), magnitude of take-off peak force, and impulse during take-off phase were calculated.

Six high caliber sprinters (100 m: 10.87 ± 0.38 seconds and 400 m: 46.75 ± 1.05 seconds) performed a series of jumps from parallel and straddle foot placement at take-off on a 2 force platform (Kistler model 9286B) to determine if a different pattern of take-off improves jumping distance. The purpose of this study was (a) to investigate the effect of the different foot movement (placement) during take-off and the initial knee joint angle used in standing long jump by the ground reaction forces analysis and 3-dimensional motion analysis (BTS SMART motion) and (b) investigate how the jump performances of different foot placement is related to the electromyography (EMG) activity (Noraxon) of 3 selected muscle groups (m.
