The Effects Of Gender On The Biomechanics Of The Hip During Athletic Maneuvers, Mikaela Boham

Boise State University Theses and Dissertations

Context: Females are two to eight times more likely to sustain an ACL injury than males participating in the same sport. The primary mechanism reported for noncontact ACL injury involves landing from a jump, unanticipated change of direction, and/or deceleration activities.

Objective: The purpose of this study was to determine if adolescent female athletes perform athletic activities with decreased hip and knee flexion angles, and decreased EMG activity of the gluteus medius relative to their male counterparts.

Design: Cohort study from local club basketball teams.

Setting: University Laboratory.

Participants: Ten healthy adolescent basketball athletes (5 females, 5 males).

Interventions: Each …

The Effect Of Instruction On Jump-Landing Kinematics In Collegiate Age Female Athletes Over Time, Jena Lynne Etnoyer

Human Movement Sciences & Special Education Theses & Dissertations

The use of verbal and video instruction is a simple feedback tool that can be implemented into almost all clinical rehabilitative and prevention programs. The purpose of this study was to determine whether self or a combination of self and expert feedback will have a long term effect on box-drop jump (BDJ), running-stop jump (RS), and sidestep maneuver (SS) lower extremity kinematics (knee flexion, knee valgus, hip flexion, hip abduction) over time in healthy college age female athletes. A repeated measures design was used. Forty-three physically active females (age=21.47±1.55years; height=l.65±0.08m; weight=63.78±12kg) were randomly assigned to three groups; 15 self feedback(S), …

Coordination Of Swimbench Freestyle In Elite And Non-Elite Swimmers: A Dynamical System Approach, Tracy H. Spigelman

University of Kentucky Doctoral Dissertations

Elite swimmers can be distinguished from novice swimmers by freestyle stroke technique. Elite swimmers move through multiple coordination modes, increases in stroke lengths, stroke rates, and body roll allowing for a more symmetrical stroke and increased speed compared with novice swimmer during 100m freestyle.

Coaches strive to improve swimmers’ performance by providing feedback about stroke technique, mostly from the pool deck where view of the full stroke cycle is obstructed by the water. Tools to assess swimming are often expensive and require extra training, which does not provide a pragmatic solution. A dryland rotational swimbench would provide a means to …
