“…Important issues to consider include light refraction and the effect of water turbulence such as bubbles and splash that are generated by a swimmers movements. 20,22 Refraction can result in the distortion of an image when light passes from a fast medium (air) to a slow medium (water). An additional concern for underwater recording is water clarity and its effect on image quality.…”

“…A central theme of this criticism is the time required to carry out video based procedures. 13,20,89 This is certainly limiting the frequency of quantitative video analysis performed in applied settings but is likely to also decrease qualitative video practices, given that video editing for multiple swimmers can be very labour intensive in its own right. It is unsurprising therefore that much research attention is currently focused on reducing the time taken to obtain pertinent information using video and on the automation of many of the laborious manual procedures involved.…”

“…Additionally, with a concurrent growth in interest in alternative methods of quantifying swimming performance, some have argued that more suitable solutions are starting to emerge, such as the use of low cost Micro-Electro-Mechanical Systems (MEMS) inertial sensor devices. 20,93,95 What is more likely is that integrated systems will Figure 9: Flowchart detailing recommendations for the key steps to be followed and decisions to be made when undertaking video analysis in swimming.…”

This paper explores the application of video-based methods for the analysis of competitive swimming performance. A systematic search of the existing literature was conducted using the following keywords: swim*, performance, analysis, quantitative, qualitative, camera, video on studies published in the last five years, in the electronic databases ISI Web of Knowledge, PubMed, Science Direct, Scopus and SPORT discus. Of the 384 number of records initially identified, 30 articles were fully reviewed and their outcome measures were analysed and categorised according to (i) the processes involved, (ii) the application of video for technical analysis of swimming performance and (iii) emerging advances in video technology. Results showed that video is one of the most common methods used to gather data for analysing performance in swimming. The process of using video in aquatic settings is complex, with little consensus amongst coaches regarding a best-practice approach, potentially hindering usage and effectiveness. Different methodologies were assessed and recommendations for coaches, sport scientists and clinicians are provided. Video is an extremely versatile tool. In addition to providing a visual record, it can be used for qualitative and quantitative analysis and is used in both training and competition settings. Cameras can be positioned to gather images both above and below the water. Ongoing advances in automation of video processing techniques and the integration of video with other analysis tools suggest that video analysis will continue to remain central to the preparation of elite swimmers.

Controlling swimming speed, i.e. the intensity of physical activity, is an important factor in swimming training. The aim of this study was to validate the new "Swimming Pace Control System" (SPCS) for the control of swimming speed in real time using visual information. Submerged at the bottom of the pool was a system equipped with LEDs and software that informed the swimmer of the appropriate distance and swimming speed. A validation test was completed with an accuracy of ±200ms which compared the predetermined time for the beam of light emitted by the SPCS and the times achieved and recorded by the electronic starting system; "Colorado Time System" (Colorado Time, USA). The average time required to move the beam simulated by the SPCS at fixed distances (150 m, 100 m, 50 m) was within the assumed error of measurement (500 ms). SPCS was proven to be useful for control of swimming speed in real-time with the aid of visual information. The system gives an objective indication of swimming speed, thus it can be used in swimming training and during empirical research. Key words visual information, swimming speed, speed control system, device validation IntroductıonObjective assessment of the achievements of athletes is a popular topic (Toussaint, Truijens, 2005). With scientific and technological progress there comes the growing possibility of obtaining feedback in order to assess technical capacity and endurance. This then leads to improvements in the performance of athletes across a range of different disciplines.The need for measuring and evaluating numerous technical parameters and physiological forces is a means of creating improved diagnostic methods and measuring devices. The focal parameters where improvements are highly sought-after are diagnostic evaluation, technique, and stamina. A multitude of methods for recording and quantifying technical data and movement provides trainers and researchers with many possibilities, which in turn results in improved athletic performance.
