Evaluating the biomechanical and performance factors of the knee joint during golf swing can provide objective and quantitative information about improving the performance and development of efficient physical training, as the legs are important for achieving an efficient swing and maximum speed of the club head in golf. In the present study, kinematic movements of the knee joint were identified during the downswing by using 3-dimensional motion analysis, and isokinetic strength was measured with driver and 5-iron clubs in 15 professional (PRO) golfers and 10 amateur (AMA) golfers. Results showed that PRO golfers had a narrower minimal angle between the thigh and lower leg in the trail knee than the AMA golfers, regardless of the club used, and the angular velocity of the lead knee was faster during the downswing with a 5-iron club in the AMA golfers than in the PRO golfers. The PRO and AMA golfers had a wider minimal angle between the thigh and lower leg, smaller total range of movement, and slower angular velocity of the trail knee when swinging a 5-iron club than when swinging a driver club. These results are expected to provide useful information to prevent golf-related injuries that usually arise in the knee joint and help improve the golf performance of amateur golfers.
评估高尔夫挥杆过程中膝关节的生物力学和性能因素，可以为改善高尔夫运动表现和制定高效体能训练提供客观和定量的信息，因为在高尔夫运动中，腿部对于实现高效挥杆和球杆头的最大速度至关重要。在本研究中，通过三维运动分析确定了下挥杆过程中膝关节的运动学动作，并在15名职业（PRO）高尔夫球手和10名业余（AMA）高尔夫球手中，使用一号木杆和5号铁杆测量了等速肌力。结果显示，无论使用何种球杆，职业高尔夫球手在后侧膝关节处大腿与小腿之间的最小角度都比业余高尔夫球手更小；在使用5号铁杆进行下挥杆时，业余高尔夫球手在前侧膝关节的角速度比职业高尔夫球手更快。与使用一号木杆挥杆相比，职业和业余高尔夫球手在使用5号铁杆挥杆时，后侧膝关节处大腿与小腿之间的最小角度更大、总运动范围更小且角速度更慢。这些结果有望为预防通常发生在膝关节的高尔夫相关损伤提供有用信息，并有助于提高业余高尔夫球手的高尔夫运动表现。
