Sports bio-mechanics, analyzes sports practice to improve its performance, develop training techniques and design accessories, materials and equipment of high performance. The general objective of sports bio-mechanical research is to develop a detailed understanding of specific mechanical sports and their performance variables to improve performance and reduce the incidence of injuries. This results in the investigation of the specific techniques of the sport, to better design the sports equipment, clothing, and to identify the practices that predispose to an injury. Given the increasing complexity of training and performance at all levels of competitive sport, it is not surprising that athletes and coaches are turning to aspects of their sport in the bio-mechanics research literature for a competitive advantage.

"It is the part of Physics that studies the state of rest or movement of bodies under the action of forces." Barbero, J.

"It has to do with the principles and methods of mechanics applied to the study of the structure and functions of biological systems." Espinoza, M.

  • Analyze each exercise or sports activity and then point out the muscle groups that are basically involved in the activity and that develop.
  • Examine and evaluate the quality of the movements involved in physical activities and sports skills.
  • Evaluate the different techniques that can be used in a given case, that is, determine the quality of a movement.
  • Improve the execution of any movement pattern and develop new techniques, that is, improve the execution of modern skills in order to contribute to the successful participation in the different physical activities.
  • Locate and correct defects in the athlete's performance.
  • Choose appropriate performance techniques optimal athletic
  • Discover the fundamental principles of body movements.
  • Discover the anatomical and mechanical basis for training in the area of ‚Äč‚Äčeducation and physical therapy.
  • Deduce the implications of movement for bones, joints, and muscles.
  • Recognize potentially dangerous activities.
  • Establish the bio-mechanical principles that should be used in the initial guide for teaching skills.

A qualitative Bio-mechanical analysis of the start, turns, butterfly style, back, chest and crawl through a Video-recording with two types of cameras: a high-speed camera and another sub-aquatic camera with four angles of Filming, to then be analyzed technically and perform the Feedback of the technical strengths and weaknesses in the execution of each natatorial skill. This report is structured in chapters, which are described as follows:


Objectives and functions of Sports Bio-mechanics
