When we talk about high performance sport, we're talking directly to overcome the limits, and in swimming, milliseconds make difference. Technical aspects such as start, swimming and turn, are the main responsible for the final result in tests of 50 and 100 meters and in these swim, the output as so important in the final result, may correspond to 10% (50 m) and 5% (100 m) of the total test time. Thus this research has developed a method of analysis of the initial phase of the swimming competitions, the start from the block to the start of the swim, individually, in order to improve their end times swim, optimizing the third stage of the (submerged phase) by means of a biomechanical analysis of the stages that comprise the start of the freestyle. Nine (9) athletes of master category participating in national competitions in 50 meters and 100 meters and have a minimum charge of five (5) workouts per week were used. For the analysis of motion images were captured by four (4) cameras, three (3) positioned perpendicularly to the test ray (2 external and 1 submerged) and one (1) positioned behind the athlete. All images were edited and analyzed by Kinovea 0.8.24 software and the velocity and acceleration data obtained were analyzed and plotted using software Microsoft Excel®. After testing and analysis of video data of each athletes was able to verify the effectiveness of the method for finding possible implementation errors in the start technic and creating correction possibilities for technical and speed events athletes (50 and 100 meters), proving to be a method of low cost and easy to handle.
