Descrizione dettagliata
During upwind sailing ("hiking"), Optimist sailors suspend their torso over the windward gunwale, secured only by foot straps over their feet and ankles. This exertion demands sustained isometric contractions of the anterior core, rectus abdominis, quadriceps, and pelvic stabilisers. Inadequate core muscle endurance and deficient postural control compromise boat handling efficiency, accelerate central and peripheral fatigue, and elevate the risk of chronic lower back disorders in young athletes.
Participants will be randomly assigned (1:1 ratio) to either:
Experimental Group (CST+TST): Participating in a 12-week standardized CST program (3 sessions per week) in addition to regular Technical Sailing Training (TST).
Active Control Group (TST Alone): Participating exclusively in the standardized Technical Sailing Training (TST) program (3-4 hours per session, 3 sessions per week).
The CST program progresses systematically across four 2-week meso-blocks, transitioning from foundational bodyweight stability (Weeks 1-6) to advanced dynamic overload and multi-planar surface instability using small fitness tools (Weeks 7-12), such as fit balls, dumbbells, weight discs, resistance bands, Bosu balance trainers, TRX suspension straps, kettlebells, and ankle/wrist weights.
