Biomechanics is the general topic that will be discussed throughout the presentation and includes a brief discussion of water resistance, propulsion, and buoyancy. As part of the rescue, the appropriate techniques and shot choice for the Timed Tow will be analyzed and justified. The science of incorporating the internal and external forces acting on the human body and the types of effects produced by these forces. By researching biomechanics you gain an understanding of endurance and propulsion and can apply it to your performance. When analyzing your own swimming techniques in water or those of others, you need to consider a number of aspects, such as body position, coordination of arms and legs, breathing technique and position of arms and legs. Skin resistance, wave resistance and turbulence resistance. There are three main types of resistance related to humans and water. A layer of fluid (boundary layer) forms on the skin that is in direct contact with the water; when the swimmer moves in one direction the boundary layer interacts with the previous layer of water, squeezing it tightly. This creates a frictional force that prevents forward movement without further propulsion, consequently called "Skin Drag". Wave drag is a buildup of fluid in front of the swimmer that creates a high pressure zone, the faster the swimmer can travel, the greater the pressure in front of them. This pressure can be reduced using appropriate streamlining techniques that result in less laminar flow displacement. Turbulence resistance is the displacement of laminar flow, when swimming it creates an area of ​​high and low pressure causing a suction effect. Using efficient optimization techniques, water displacement is minimized and fewer vortices... in the center of the paper... time with the pitch to avoid increased drag. Minimal errors occur when I lose coordination with my arms and legs causing my feet to drop creating more resistance, overall my technique in most cases proves to be effective and efficient. This is an ineffective tow due to the patient not being on top of the swimmer, my stepping technique is correct. However, if I were to properly align my center of buoyancy with the patient, it would be a more effective tow. In this way further drag and resistance would be avoided, the amount of water displaced would cause the formation of more vortices creating a suction effect. Overall my performance for the timed tow proved to be inefficient causing the patient to be submerged under water at some stages, the positive aspects of the tow are the correct grip and steps. This concludes the overall technique and biomechanics of my performance.
