Abstract
Abstract Aims: This study aimed to present a technical evaluation proposal for the crawl stroke that can be used with large groups of swimmers, based on an observation sheet. Methods: Fifteen healthy university students aged between 18 and 30 years were chosen to participate in the study. The subjects were recorded swimming at a distance of 50 meters using the crawl technique at a comfortable and self-determined speed. The recordings simulated docent observation capacity. Five swimming teachers were selected to evaluate the proposed checklist and the subjects’ technique. An observation sheet was created based on references present in literature containing ten items that are considered fundamental for swimming movements. The study was divided into (i) checklist validation, (ii) intra-evaluator consistency, and (iii) inter-evaluator consistency. Results: The proposed checklist fulfilled the validity criteria, with intra-evaluator consistency varying between reasonable and substantial, with k varying between 0.36 and 0.73 respectively, while inter-evaluator consistency was deemed reasonable (k = 0.24). Conclusion: According to the results that were obtained, the suggested list is valid and adequate for what it proposes to do.
Highlights
The vast amount of literature available regarding swimming technique evaluation in different circumstances demonstrates its relevance in learning and practicing swimming.[1,2,3,4,5] many proposals require sophisticated equipment and a large amount of time for the testing and evaluation processes to occur and for the feedback to return to the swimmer and the teacher
The subjects swam 50 meters using the crawl technique at a comfortable, self-determined speed in a pool measuring 25 meters in length. Their swimming movements were recorded by the researcher, who accompanied the movement from a two-meter distance using a lateral and superior viewpoint, simulating docent observation capacity
Regarding content description clarity on the observation sheet, three evaluators considered it very easy to understand and two deemed it easy to understand; 4 evaluators rated the technical pertinence of the movements present on the sheet as very adequate and one judged it adequate
Summary
The vast amount of literature available regarding swimming technique evaluation in different circumstances demonstrates its relevance in learning and practicing swimming.[1,2,3,4,5] many proposals require sophisticated equipment and a large amount of time for the testing and evaluation processes to occur and for the feedback to return to the swimmer and the teacher. Knudson and Morrison[6] suggest that the studies should involve simpler proposals, especially for beginners, which highlight the movement's basic characteristics. Aside from being scarce in the literature, evaluation proposals of this type mostly deal with adaptation to the water environment[7,8] and general abilities in the water.[9] they are extensive, focused on non-essential characteristics, or are directed towards young high-performance swimmers.[6,10,11] As such, little has been devised for beginning swimmers of various ages, whose swimming movement patterns require refinement
