Abstract text THE EFFECTS OF A COMPUTERIZED BIOMECHANICAL ANALYSIS AS A TEACHING STRATEGY ON THE RECOVERY SHOULDER OF THE FRONT CRAWL SWIMMING Introduction This study was computed to test for significance of the effects of three teaching strategies on the humerus of rotation and linear displacement of the breathing and non-breathing recovery arms of the front crawl swimming. Methods Seventy registered Iran Swimming boys and girls between the ages of 8 through 12 years were given “intact groups” assignment. The participants were selected from Shiraz Swimming teams. The study included 25 participants for each of the following four groups: (1) control, (2) traditional teaching strategy, (3) traditional and videotape teaching strategy, and (4) traditional and System computerized biomechanical analysis teaching strategy. Participants were individually videotaped while swimming 25 meters of the front crawl swimming. Measurements from the radius of rotation and linear displacement of the radia and glenohumeral joint segment were calculated by the NEAT System software. Results It was determined that all treatments effected increase in radius of rotation and linear displacement. Therefore, all of the teaching strategies caused significant improvement in the radius of rotation and linear displacement for the breathing recovery arm of front crawl swimming. Discussion Physiological benefits included enhanced awareness of correct shoulder elevation that could improve swimming skill and swimming times. Psychological benefits might have included increased self-concept. Benefits also included knowledge of better teaching strategies such as computerized biomechanical analysis to enhance motor learning. References Craig A.B., Pendergast D.R.
