Core Strength Training, Anthropometry, and Postural Control in Youth Optimist Sailors

31. August 2026 aktualisiert von: Anna Antonia Valenzano, University of Foggia

Core Strength Training Influences Anthropometric Profile And Postural Control In Optimist Sailors

Optimist dinghy sailing is a highly demanding youth watersport characterized by prolonged, high-intensity isometric hiking postures and rapid dynamic weight shifts required to preserve boat trim, balance, and sail power output. The core (lumbar-pelvic-hip complex) functions as the central dynamic link in transferring kinetic forces between the lower limbs and trunk during continuous open-water maneuvers. This study is designed as a 12-week randomized controlled interventional trial to evaluate the effects of a periodized, circuit-based Core Strength Training (CST) program integrated into routine Technical Sailing Training (TST) compared to TST alone. Primary endpoints evaluate adaptations in the anthropometric profile (skinfold thickness, circumferences, muscle mass percentage) and postural control parameters (Center of Pressure displacement and sway velocity measured via computerized force platform posturography) in competitive youth Optimist sailors.

Detaillierte Beschreibung

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.
