The project aimed to systematically investigate the biomechanical characteristics as well as the acute and mid-term effects of eccentric quasi-isometric (EQI) muscle actions, a training approach increasingly used in sport and rehabilitation practice but previously only sparsely examined in scientific literature.<\/p>\n The project included controlled experimental studies focusing on the knee and ankle joints. The research addressed the temporal structure of EQI contractions, torque development, mechanical impulse, fatigue responses, and comparisons with isokinetic and traditional eccentric loading protocols. Measurements were conducted using an isokinetic dynamometer, standardized mechanical assessment protocols, and ultrasound-based evaluation of the muscle\u2013tendon unit.<\/p>\n The findings provided a more precise biomechanical characterization of EQI muscle actions and contributed to understanding their acute responses and adaptive effects compared to other forms of resistance exercise. Project results were published in international peer-reviewed journals indexed in WoS and Scopus and presented at scientific conferences. Several open-access publications have already received initial citations in the international research community.<\/p>\n The project also contributed substantially to postgraduate education, as it was directly linked to doctoral research training. The developed methodological approaches and research findings have been integrated into undergraduate and postgraduate teaching in the fields of kinesiology, biomechanics, and rehabilitation sciences.<\/p>\n [\/et_pb_text][et_pb_toggle title=”Publications” _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n Li\u010den, U., Oranchuk, D.

The simplest way to describe EQI contractions is holding a position until isometric subsequent eccentric phase. The theoretical basis for the use of EQI is well established, and some short-term (e.g., less muscle soreness and lower impairment in neuromuscular performance) have been demonstrated. However, remain unexplored: what are the kinematic and kinetic characteristics of EQI multi-joint exercises? How do the term effects of EQI training compare to the effects of comparable eccentric training? This project will establish be used for further intervention research and practical application. Thus, the overarching purpose of this project objectives of this project are to a) assess the kinetic and kinematic characteristics of selected EQI exercises and long-term effects of EQI with comparable isometric and eccentric exercise protocols on muscle architecture, neuromuscular<\/span> [\/et_pb_toggle][et_pb_text _builder_version=”4.27.5″ custom_padding=”||3px|||” global_colors_info=”{}”]<\/p>\n \n \u00bbThe authors acknowledge the project EQI-TRAIN Establishing scientific foundations for eccentric quasi-isometric resistance training<\/strong> was finacially supported by the Slovenian Research and Innovation Agency.\u00ab<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":" DURATION OF THE PROJECT: 1. 9. 2023 – 31. 8. 2025 LEAD PARTNER:University of Primorska, Faculty of Health SciencesPOSTDOC RESEARCHERAssoc.
