Abstract
Introduction
Golf is a recommended form of physical activity for older adults. However, clinicians have no evidence-based research regarding the demands on the hips of older adults during golf. The purpose of our in vivoobservational study was to quantify the hip biomechanics of older adult golfers.
Methods
Seventeen healthy older male golfers(62.2±8.8 years, handicap 8.7±4.9) free from orthopaedic injuries and surgeries volunteered for participation in this IRB-approved study. A 10-camera motion capture system recorded kinematics, and two force plates collected kinetic data. Participants performed eight shots using their own driver. Data processing was performed in Visual3D. The overall range of excursion and three-dimensional net joint moments normalized to body weight for the lead and trail hips were extracted.
Results
Kinematics (mean excursion and range) of lead and trail hips in all three planes during a golf swing are presented in Table 1. The trail leg experiences higher excursion in the sagittal plane, while the lead leg has more frontal plane movement. Average maximum net joint moments of the lead and trail hips were 1.2 ± 0.2 and 1.7 ± 0.3 Nm/kg, respectively.
Conclusion
Our study is the first to quantify the kinematics and kinetics of the hip joint in healthy older male golfers. While the golf swing is often considered to be a predominant transverse plane motion, our results indicate considerable excursion at the hip joints in all three planes. Furthermore, the trail leg experiences 40% greater loading than the lead leg throughout the swing, suggesting that the trail leg may have a larger impact on golf performance while also leaving it more susceptible to overuse injury. For clinicians with patients who experience osteoarthritis of the hip or who have recently undergone hip surgery, this study may provide novel insight into the demands of golf on the hips.
