This study aimed to explore the interplay of neuromuscular characteristics of handgrip and morphological characteristics, along with personality traits, in well-trained and elite athletes. The research involved a sample of 155 well-trained and elite athletes. A cross-sectional design was employed. A sliding device that measures isometric finger flexor force was used to assess handgrip neuromuscular characteristics. Key morphological characteristics, including body height, body mass and body mass index, were measured using a portable stadiometer and the InBody 720 device. Personality traits were evaluated using the Big Five plus Two Questionnaire. The study found numerous significant correlations, among which the positive association of positive valence and maximum force of the dominant (r=0.77) and non-dominant (r=0.82) hand in a group of female elite athletes stand out. The results revealed gender-specific patterns in the relationships examined. Canonical discriminant analysis indicated the presence of statistically significant discriminant functions for all variables assessed, both in female (Wilks’s Λ=0.44, χ²(22)=37.67) and male samples (Wilks’s Λ=0.59, χ²(20)=41.18), with 90% accuracy for females and 80% accuracy for males when discriminating between elite and well-trained athletes. The results support the need for further research in this area to enhance our understanding of the identified correlations.
