Overview

Analysis reveals pitch kinematics influence performance in youth swimmers, suggesting optimized techniques improve alignment.

Key Points

  • This research investigates the relationship between upper-body pitch control and sprint butterfly performance in youth swimmers.
  • 41 competitive swimmers aged 9-11 performed two maximal 25-m butterfly trials
  • Head, shoulder, and hip pitch kinematics assessed using inertial measurement units
  • Independent t-tests compared groups based on speed
  • Pearson correlations examined performance associations
  • Faster swimmers showed smaller head pitch angles during the Breath phase
  • Greater shoulder pitch velocities and frequencies correlated with speed
  • Shorter pitch times and lower pitch deviation indices in faster swimmers
  • Moderate correlations between certain head and shoulder metrics and sprint time
