Key result
A 47-week swim season links to ~23% faster breaststroke times in youth, driven by kinematics.
Why the study?
Understanding fluctuations and associations between swimming performance-related variables provides strategic insights into a swimmer's preparation program.
Does a 47-week swimming training season improve anthropometrics, maturation, and kinematics in 12-year-old and under age-group swimmers?

A 47-week swimming training season in young swimmers significantly improved performance and kinematics, with network analysis highlighting the complex interplay between stroke rate, stroke length, and arm span.
Fiori et al. (2022) conducted an observational in Healthy age-group swimmers (n=20). Swimming training season vs. Baseline (before training season) was evaluated on 25-m breaststroke (BREAST) swimming performance (T25) in seconds (Hedges' g 1.26, p=<0.001). A 47-week swimming training season significantly improved 25-m breaststroke and butterfly performance in 12-year-old and under swimmers, with improvements driven more by kinematics than anthropometrics.
