Kinematic differences between front crawl sprint and distance swimmers at a distance pace

Area of Science:

• Sports Science
• Biomechanics
• Swimming Performance

Background:

• Front crawl swimming involves complex kinematics.
• Distinguishing between sprint and distance specialists is crucial for training.
• Understanding kinematic differences informs coaching strategies.

Purpose of the Study:

• To investigate kinematic variations between sprint and distance front crawl swimmers.
• To compare swimming techniques at a consistent distance pace with a six-beat kick.
• To determine if specialized techniques are necessary for different swimming disciplines.

Main Methods:

• Seven sprint and eight distance male swimmers performed a maximal 400m swim.
• Kinematic variables were captured using six gen-locked cameras in a calibrated space.
• Statistical analysis included independent t-tests and effect size calculations.

Main Results:

• Distance swimmers exhibited significantly greater average swim velocity.
• Moderate effect sizes were observed for elbow angle range and hip roll magnitude.
• No significant differences in most kinematic variables were found between groups.

Conclusions:

• Sprint and distance front crawl swimmers demonstrate similar techniques at a distance pace.
• Coaches should not promote distinct techniques for these groups.
• Focusing on velocity may be more beneficial than technique differentiation.
