Abstract

ABSTRACT
Objective: Purpose of this study was to compare kinematic parameters between professional and non professional swimmers. It will help in understanding of kinematic parameters in swimming.
Methodology: We took sample of 5 postgraduate students who were physically healthy and active but they were not professional swimmers. All subjects were explained about whole procedure and warm up was performed for 10 minutes. Head was reference point to take readings as all due to the differences that exists between subjects in terms of arm lengths. As a reference values for our comparisons, data obtained from 2011 Szczecin European Short course Championships men’s finals of 50, 400 and 1500m freestyle was used. We carried out Pearson’s Correlation between height, SL and SF to determine the effect of height on speed of swimming.
Result: Looking at the results, it can be said that, not unexpectedly, there are large differences between the groups, especially in the fast speed category, where all of the selected variables (stroke frequency, length and speed) are clearly higher for the professional swimmers. Additionally, professionals having similar stroke frequencies to IMPAS in the remaining two speed categories, albeit producing much higher speed and stroke length values would suggest that professionals (again, not unexpectedly) are more efficient at swimming by attaining more velocity and distance from the same number (or more precisely, frequency) of strokes.
Conclusion: There are different aspects that have to be taken into account in order to analyze the swimming competition. The stroke length is the most determinant factor and it would be related to the success. Stroke frequency, is not a significant factor that could explain the performance in swimming competition. However, it is has importance also for coaches and swimmers.

Key words: swimming, kinematic parameters, professional and non professional swimmers
