Biomechanical, Anthropometric, and Psychological Determinants of Barbell Back Squat Strength

Abstract: Previous investigations of strength have only focused on biomechanical or psychological determinants, while ignoring the potential interplay and relative contributions of these variables. The purpose of this study was to investigate the relative contributions of biomechanical, anthropometric, and psychological variables to the prediction of maximum parallel barbell back squat strength. Twenty-one college-aged participants (male = 14; female = 7; age = 23 ± 3 years) reported to the laboratory for two visits. Th… Show more

“…Recent research serves to support our findings in context of the BBS exercise. For example, Vigotsky et al (2019), recently reported no relationship between BBS 1RM and isometric spinal extension strength. In their discussion, Vigotsky et al suggested that, during a BBS exercise, ‘the spinal erectors need only resist the net joint moment as well as a small abdominal co-contraction, which does not necessarily increase with load’.…”

“…Longer lower extremity lever arms have been associated with higher joint loads. 49 Furthermore, studies have shown moderate positive correlations between thigh segment length and knee extension moment 62 as well as between stature and knee extensor strength in male adults. 56 Thus, a longer period of growth resulting in greater stature and longer thigh segment lengths may manifest as greater quadriceps strength and thus a tendency toward greater extension during landing.…”

“…This study and its discussion have focused primarily on single muscle group hypertrophy and single-joint isometric strength gain. The larger question of multi-joint and dynamic strength gain is perhaps more relevant, but unfortunately much more complex (Vigotsky et al 2018).…”
