Anterior cruciate ligament (ACL) injuries remain a significant, season-ending injury in youth soccer, with young female athletes exhibiting higher incidence rates compared to young male athletes. ACL injury rates increase with older ages, with female soccer players 15 years or older being at an almost twofold increased rate of injury compared to young female soccer players. Several biomechanical and neuromuscular changes occur during the maturation process, becoming more prevalent in young females, that can place them at an increased risk for ACL injury. These biomechanical and neuromuscular changes can affect how efficient young females are when completing high-risk, dynamic tasks …

Developmental dysplasia of the hip (DDH) is characterized by abnormal bony anatomy, causes pain and functional limitations, and is a prominent risk factor for premature hip osteoarthritis. Although the pathology of DDH is believed to be mechanically-induced, little is known about how DDH anatomy alters hip biomechanics during activities of daily living, partly due to the difficulties with measuring hip muscle and joint forces. Musculoskeletal models (MSMs) are useful for dynamic simulations of joint mechanics, but the reliability of MSMs for DDH research is limited by an accurate model representation of the unique hip anatomy. To address such challenges, this …

Biomechanics Of The Lower Back During Repetitive Deadlifts, With And Without Body Armor, Vanessa J. Ramirez
Theses and Dissertations--Kinesiology and Health Promotion
Background: Low back pain is a significant problem and one of the primary musculoskeletal-related conditions affecting active-duty service members [1]. Since more than two-thirds of U.S. soldier occupational tasks involve lifting from floor level to waist height [2], increasing individual lifting capacity is strongly correlated with performance with these tasks [3]. Training for the first Army Combat Fitness Test event (3RM deadlift) to improve lifting capacity directly relates to performing carrying/lifting military tasks. One training modality that can be used in training programs to improve lifting capacity is repetitions-to-failure (RTF) or repetitive lifting to volitional failure [4-8]. RTF is widely …
