indent Abstract
The purpose of this research is the determination of a prediction model that could predict 50m and 100m fin swimming results on surface. The sample of this research consisted of 9 fin swimmers of competitive level. All participants swam 50 and 100 meters on the water surface with monofin and a snorkel with maximum intensity. In two next sessions, force of the leg extensors and ankle extensors were measured in the workout gym with a dynamometer. The results of this study concluded in a potential statistical significance of regression analysis for 50m fin swimming with snorkel on the surface of the water. Relative force values of ankle and leg extensors are better predictors of 50m fin swimming. No similar results were found for 100m fin swimming. These findings probably suggest that in shorter distance of 50m fin swimming, force variables of extensor muscles play a greater role in comparison to longer distance of 100m fin swimming. The measurement of force of legs in fin swimming is of particular interest because legs are mostly responsible for the propulsion in fin swimming and should further be studied with other force protocols, different exercises and larger sample.
