Sports such wrestling, track-and-field events or weightlifting often require use of maximal muscular strength production in its performance (Siff, 2001). Sport scientists and practitioners are unable to change athlete’s genetic characteristics through sport training, while muscular strength can be improved, especially through resistance training, which gives support to future researches in this type of training (Suchomel et al., 2016). If the main goal (i.e. improving muscular strength) of resistance training is put aside, its benefits are numerous. These benefits include increase in bone mass, reduced blood pressure, increase muscle and connective tissue cross-sectional area, reduced body fat, and it may relive low back painif is used correctly (Kraemer et al., 2002). Muscle hypertrophy (grow of skeletal muscle) and gains in strength production (neuro-muscular adaptations) are fields of interest not only for athletes who wants to upgrade performance, but also for recreationalists who simply wants to promote its body composition or to increase their capacity to perform tasks which require muscular strength (Bird et al., 2005).General factors that influence production of maximal muscular strength are morphological (i.e. musclecross-sectional area, architecture and anthropometric factors) and neural factors (musculo-tendinous stiffness, motor unit recruitment, rate coding, motor unit synchronization, and neuromuscular inhibition) (Suchomel et al., 2018). Morphological factors are often neglected in importance of production of muscular strength, but they play very important role in its production. Related to this are the anthropometric factors such as body mass, height and segment lengths. An individual’s anthropometry will contribute to their capacity to produce muscular strength and force, so this needs to be considered with resistance training. Studies suggest that for strength-based resistance training sports such as powerlifting and weightlifting anthropometry plays an important role in performance (Keogh et al., 2007; Lovera and Keogh, 2015; Fry et al., 2006; Storey and Smith, 2012; Reya et al., 2019; Cholewa et al., 2019).To our knowledge studies that have examined influence of different morphological variables (derived from electrical bioimpedance, anthropometry and ultrasound diagnostics) on muscular strength are very rare, in single-joint and multi-joint exercises. With the above backdrop in mind, the present paper aims to assess the predictor contribution of different morphological variables in the manifestation of muscle strength in biceps curl and parallel squat exercises.Expectations are that the obtained experimental data could significantly contribute to the understanding of influence different morphological factorson muscular strength production, what is of the most significance for programing resistance training, either for athlete or recreationalists. https://phaidrabg.bg.ac.rs/o:26128 info:eu-repo/semantics/article
