Kinesiological analysis of crawl. A case study

Abstract

With the evolution of swimming in recent years, the front crawl has become very fast, requiring the best physical performance of the athlete. But today, the difference between victory and defeat at world level has become technical details, that is, more efficient strokes, faster and lower breaths, stronger kicks with less knee amplitude. The objective of this study was to perform a kinesiological study, with emphasis on the needs of body adjustments and technical changes necessary in three phases of the front crawl, providing improvements in the performance of the movements to improve the efficiency and performance of the athlete. The sample consisted of a male swimming athlete, in training and competition at the national level. The data were collected through an analogue waterproof camera (ISEC brand, Chinese) with sagittal plane filming and analyzed using Windows Movie Maker 2.1.426.0 and Adobe Photoshop CS6 13.0.1.3. The result, we describe the main agonist muscles required, the performance and the efficiency of the athlete in each phase of the movement. We verified the need for adjustments to adapt technically and kinesiologically each phase. We conclude that this study will be of great value as a basis for analysis, correction and improvement of the technique, thus improving the performance of athletes.
