Knee Biomechanics Of Older Adults During Common Recreational And Daily Activities, Julie Lynn Pfeiffer
Knee Biomechanics Of Older Adults During Common Recreational And Daily Activities, Julie Lynn Pfeiffer
Masters Theses
Among older adults, socialization is a key motivating factor for participation in physical activity. In order to develop evidence-based physical activity recommendations for older adults with knee pathologies a better understanding of knee biomechanics during social recreational activities is needed. The purpose of this study was to determine knee joint kinematics and kinetics in healthy older adults during golf and bowling. Knee biomechanics during these recreational activities were also compared to those experienced during activities of daily living. Motion analysis data were collected as subjects performed walking, stair ascent, stair descent, and either golf or bowling. Knee angles, peak knee …

Purpose: To determine if any kinematic differences exist between two common sprint drills (A- and B-drills) and maximal sprinting. Methods: 12 collegiate sprinters (19.17±1.11 y/o) granted informed consent were filmed performing two 40-meter sprints, A-skips, and B-skips. Three-dimensional motion analysis tracked the coordinates of 24 reflective markers and resulting joint kinematics were computed. Results: Statistical analysis revealed that sprinting yielded a significantly lower maximum hip flexion (p=0.015) but a significantly higher minimum ankle angular velocity (p=0.012) and step rate (p=0.000) value than A-drills. When compared to B-drills, sprinting values were significantly lower in maximum hip flexion (p=0.047), minimum knee flexion …
