It is proposed that the training session be conducted on the ground with controlled light-dynamic illumination to be generated by small-size laser or other light emitters fastened on the athlete’s head. For safety the emitters are to be installed so as to prevent the trainee’s eyes from direct emanation. The emitters create mobile unallowed and allowed zones seen as the figures of various shape to be used for simulation of the training modes. The figures are controlled by software and hardware system including a gyroscopic orientation system of light emitters and a system of positioning of the athlete on the playing court. The system of gyroscopic orientation of light emitters is placed together with the emitters and depending on the head rotation, neck bends and vertical movements of the athlete's head and his/her movements on the playing court during the training session. The system of gyroscopic orientation automatically adjusts the position of the figures, while maintaining their target location and movement set by the selected training programme. The training can take place outside of specially equipped athletic field, on any smooth surface. The contours of the mobile unallowed and allowed zones are clearly visible and have no shadow formations. The method of motor skills development proposed incorporates the principles and techniques of sports coaching used for training both certain athletes and sports teams. The method facilitates in personalising the training tasks, acquiring playing skills by simulating different complex game situations, improving the efficiency of training, bringing it closer to the real play conditions, developing game thinking. The method can be used for training teams of different profile specialising in football, hockey, handball, rugby, basketball and other team sports.

The traditional approach to evaluate gymnastics by subjective rating requires an experienced eye, posing challenges to teachers and coaches who may not have the necessarypersonal experience. This study presented a simple and objective method for analyzing a dynamic, asymmetrical and multi-planar gymnastics skill (cartwheel). Two studies were conducted to analyze videos of cartwheel performances by quantifying ankle, knee, hip, shoulder, and torso angles using an open source freeware. Study 1 tested whether the method could differentiate between highly trained gymnasts and novices, and assessed the reliability of the method. Study 2 evaluated whether the method could track the progression of novice learners: Performances of an experimental and a control groups were compared before and after a 20-minute intervention. Results showed excellent intra- and inter-rater reliability (intra-class correlation > 0.90, standard error of measurement < 5°). Highly trained gymnasts displayed better forms than novices at the ankle, knee, shoulder and torso (all p < 0.05).After brief practice, novel learners showed improvements at the knees (p = 0.007) and ankles (group × time p = 0.05) when performing a cartwheel. In conclusion, the proposed video analysis method demonstrated good potential for assessing the cartwheel in a simple and objective way.

Seen the Soccer Accuracy kicking is formulated based on the esteem of the player. Our interest in this study came from the reality of the means of assessment available to Algerian coaches. Where the Limitations of existing methods for evaluation of kicking success in soccer, do not allow them to judge the progress of them players. The objectives of this study are to determine the impact of vessel information on Accuracy kicking success among 20 soccer players under18 years, representing the team Sidibel abbes for year 2014-2015 in Algerian championship according to them results in the proposed situations case the Eye dominance and Binocular vision in accuracy test. Based on statistical analysis applied, we confirm: • There is a strong positive correlation relationship between the proposed visual situations (Eye dominance- Binocular). • The weakness of the research sample in binocular vison situation return to the ability of brain to judge the received images from the both eyes. • Developing estimations accuracy kicking success required that the dominant eye must provide the most of the visual input to the brain. Where the most important factors influence the Accuracy kicking success among our soccer in the frequent situation consisted in the conflict between dominant eye and weak.
