Principal Technique Components for Young Swimmers Evaluation. Enhancing the Free Observation Method

Area of Science:

• Sports Science
• Biomechanics
• Motor Learning

Background:

• Accurate assessment of swimming technique is crucial for young athletes' development.
• Existing evaluation methods may lack objectivity or be overly complex.
• A need exists for a practical tool to quantify technical proficiency in competitive swimmers.

Purpose of the Study:

• To develop and validate a technique evaluation tool for young swimmers.
• To identify, weight, and highlight common errors across the four major swimming strokes.
• To establish a reliable method for calculating swimming technique scores.

Main Methods:

• Utilized the Technique Papadimitriou (Tec Pa) tool for evaluation.
• Involved 86 regional-level young swimmers (8-12 years old).
• Applied Principal Component Analysis for Categorical Data (CATPCA) to determine the significance of 12 technical points per stroke.

Main Results:

• The Tec Pa tool demonstrated high reliability (Cronbach's Alpha: 0.87-0.92) across all four strokes.
• Weighting of technical points varied across strokes, providing stroke-specific insights.
• Established objective scoring ranges for key technical elements in butterfly, backstroke, breaststroke, and front crawl.

Conclusions:

• The Technique Papadimitriou tool offers a valid and reliable method for assessing swimming technique in young athletes.
• Coaches can effectively use this tool for technique evaluation without specialized equipment or software.
• The findings facilitate targeted feedback and improved training strategies for young swimmers.
