Effect of an 8-week technical tethered swimming program on front kinematics in adolescent swimmers

The aim of this study was to assess the effect of long-term use of technical tethered swimming on kinematics of front crawl swimming, and swimming performance. The experiment was attended by 19 girls Thirty-nine adolescent swimmers (19 girls and 20 boys, aged 13 years) participated in the study. The participants were randomly assigned to two groups. The experimental group received additional technical tethered swimming protocol. At this time, the control group performed standard technical training in free swimming. The study included an 8-week training cycle. Changes in swimming technique were assessed using a device equipped with a triaxial gyroscope and a triaxial accelerometer, with a particular focus on body roll and yaw rotationof the athletes. Significant changes were observed in yaw rotation (ω_maxY, ab_max) and body roll (A_maxR) variables. The study showed that a training protocol involving technical tethered swimming can positively affect front crawl kinematics in adolescent athletes when applied over the long term.
