Objectification, comparison, and degree of association of maladaptive indicators in athletes Aim: The aim of this study was to identify bilateral and unilateral asymmetries in different components of neuromuscular testing among young athletes, and compare these asymmetries with respect to sport type, age group, performance level, and gender. The secondary aim was to assess the degree of association between types of asymmetry (morphological, balance, strength, and running asymmetry). Methods: The sample population consisted of young male and female athletes aged 10 to 19 with various sports specializations. The participants were grouped by various factors: predominant characteristic of the sport (symmetrical (SY), asymmetrical (ASY), hybrid (HY)); chronological age (10-12 years, 13-15 years, 16-18 years); performance level (elite, sub-elite), and gender. Asymmetry was assessed from morphology and various neuromuscular assessments: distribution of muscle mass on the lower limbs (MA), bilateral differences in the size of the center of pressure path length (APS), maximum active (APF) and impact peak force (IPF) and force impulse (FI) at initial (Z) and final (K) running speed, bilateral asymmetry of knee extensors (Q:Q) and flexors (H:H), and H:Q ratio (unilateral asymmetry) at three angular velocities...
