While working on our project, we found this article in the Journal of Sports Science and Medicine:
Although the title may make this project at first seem simple, it actually included a detailed, 9 page research report, written by 7 professors from Portugal, all with PhD (doctorate) degrees. They also determined formulas such as this: We soon realized that applying the necessary number of these complex formulas to determine the overall "perfect stroke" technique was far too complex to complete during a 6 month period, having the limited knowledge of two high school juniors. (Who have never taken a formal calculus or a physics class) Although, throughout the process of completing this project, we did teach ourselves a considerable amount in both subjects. With this in mind, we decided to take a different approach. We applied the principles, along with demonstrations of these techniques, to make |
estimate the most efficient stroke techniques for general use.(The difference between these hypotheses is that the principles are based more upon previously determined research in fluid dynamics (hydrodynamics) and physics, as opposed to equations, which provide more mathematical accuracy.)
- Knowledgeable coaches will be better able to assist their swimmers in becoming more efficient in the pool.
- Research can develop better swimmers, and the scientific approach is preferable to the trial-and-error method of coaching.
- Knowledge will not allow swimmers to be fooled by every new fad that comes along.
| What we covered in our research: - Basic accepted stroke techniques
- Most efficient streamline, justified by equations
- Buoyancy in swimming, explained through Archimedes' Principle and other equations
- Newton's Laws of Motion, justifying resistance and propulsion forces while swimming through a fluid
- Drag and resistance, reducing these basic forces as much as possible for faster strokes
- Other applications, branching out from basic knowledge for application in new research fields
- In our research, we worked with these principles to analyze general aspects of swimming, and ways to make it more efficient, combining previous research and data, including graphs, empirical theories, etc.
This video shows one type of 2D underwater motion analysis software that researchers use to view basic movements in swimming. Programs like this allow them to analyze the swimmer's kick movements, and to estimate the efficiency of each individualized movement. |
