Propulsion and symmetry within the stroke cycle: a comparison between tethered and free swimming

Key Points

• The research aims to analyze propulsion and symmetry during the swimming stroke cycle in tethered versus free conditions.
• Comparison of hand force during tethered and free swimming
• Analysis of entry and catch phases in stroke cycle
• Hand force is significantly greater in tethered swimming than in free swimming
• Differences in the entry to catch phase explain the variation in hand force
