Abstract


The study aimed at identying the effect of visual and verbal feedback on some kinematics variables in breaststroke swimming on a sample of 20 students of swimming course (2) in the first semester of the academic year 2012/2013. The sample was divided into two groups; the first group includes (10) students which received visual feedback, and a group of (10) students which received literal feedback. Two video filming cameras (Sony) (25-Hz) were used with Kenova analytical software order to find the value of kinematics parameters. The components of study parameters consisted of: (Time of first 25 meters of swimming; time of last 25 meters of swimming; time of 50 meters of swimming, number of arms strokes in the first 25 meters; number of arms strokes in the last 25 meters, number of arms strokes in the 50 meters; stroke length of arms; stroke rate of arms; speed in 50 meters breaststroke swimming; and coefficient of efficiency). The results of the study suggested that visual and verbal-based kinetic analysis feedback has a role in improving the level of kinetic parameters study in the 50 meters breaststroke swimming in the (2) second category of the group of sample students. These are statistically significant differences between the groups of visual and verbal feedback in improving the parameters of (time of swimming in the last 25 meters, time of swimming in the overall 50 meters, speed of 50 meters of breaststroke swimming) in favor of the members of the visual feedback group. The researchers recommended that it is necessary to use of the results of kinematics analysis to evaluate students' performance when giving the feedback in order to detect the points of weak performance for further modification.
