Background In this study, kinematics and kinetics of the lower extremity joint and the lumbar
lordosis during two different symmetrical lifting techniques (squat and stoop) were examined …

barbell load on relative muscular effort in squatting. J Strength Cond Res 26 (10): 2820 …

Background. Knowledge of the musculoskeletal loading conditions during strength training
is essential for performance monitoring, injury prevention, rehabilitation, and training design …

The aims of this study were (1) to assess the relationship between joint position (JPS) and
force sense (FS) and muscle strength (MS) and (2) to evaluate the impact of long‐term …

Hip extensor strategy, specifically relative contribution of gluteus maximus versus
hamstrings, will influence quadriceps effort required during squat exercise, as hamstrings …

Walking after stroke is often described as requiring excessive muscle co-contraction, yet,
evidence that co-contraction is a ubiquitous motor control strategy for this population …

After spinal cord injury (SCI), the reorganization of the neuromuscular system leads to
increased antagonist muscles' co‐activation—that is, increased antagonist vs. agonist …

Introduction: We examined generalized versus joint‐specific influences on muscle
coactivation. Methods: Muscle coactivation was assessed during maximal isometric and …

The purpose of this study was to examine load-dependent differences in lower-extremity
biomechanics between the back squat (BS) and front squat (FS) exercises. Eleven NCAA …
