Abstract Delayed-onset muscle soreness (DOMS) is induced by unaccustomed and/or strenuous repetitive eccentric or isometric contractions. However, the exact mechanism of DOMS far from entirely known for more than 120 years. A recent neurocentric theory proposes that a non-contact acute compression axonopathy initiated on intrafusal proprioceptive Type Ia terminal, in form an autonomously acquired transient Piezo2 channelopathy under eccentric/isometric contractions and allostatic stress. The current study was executed seventeen young male handball players Hungarian National Handball Academy. dynamometer-based exercise protocol used order to induce stabilometry measure postural sway before right after aforementioned inducing protocol. findings this contrast fatigue related ones, namely it decreased with open eyes.
