Effects of a Minimalistic Approach in Supramaximal Accentuated Eccentric Loading

This preregistered randomized controlled trial investigates the effects of a 6-week, low-volume accentuated eccentric load (AEL) squat training compared with traditional resistance training and a non-training control in healthy, strength-trained men. Primary outcomes are changes in concentric and eccentric maximal squat strength. Secondary outcomes include muscle morphology and stiffness assessed by ultrasound, neuromuscular activation (EMG), and functional performance (jump and force–time measures). Participants are randomly allocated to one of three groups and complete identical pre- and post-intervention testing under standardized laboratory conditions. The study aims to determine whether eccentric overload can induce meaningful neuromuscular and morphological adaptations with minimal training volume.
