There is a risk of hip injury in dives to the side by soccer goalkeepers. In this study, we assessed hip loading in goalkeepers when performing such dives. The experiments were conducted in a laboratory setting using an in-ground force plate as well as on a grass surface when the athletes were equipped with force sensors. The forces acting on the hip were measured and high-speed video analysis was performed, allowing the investigation of the dive characteristics and techniques. The peak force values recorded in the laboratory setting ranged from 3 to 8 kN, which corresponded to 4.2-8.6 times body weight. The vertical impact velocities reached 3.25 m . s(-1). In the field experiments, a hip loading of 87-183 N . cm(-2) was determined. We found that goalkeepers who perform a rolling motion reduce their hip loading. The data provided by this study add to the biomechanics database and contribute to the establishment of injury criteria. Such information is necessary to develop and implement strategies to help prevent hip injuries.
足球守门员向侧面扑救时存在髋部受伤的风险。在本研究中，我们评估了守门员进行此类扑救时的髋部负荷情况。实验在实验室环境中使用地面测力板进行，同时当运动员配备力传感器时也在草地表面进行。测量了作用在髋部的力，并进行了高速视频分析，从而能够研究扑救的特征和技术。在实验室环境中记录的峰值力值范围为3至8千牛，这相当于体重的4.2至8.6倍。垂直冲击速度达到3.25米·秒⁻¹。在现场实验中，确定髋部负荷为87至183牛·厘米⁻²。我们发现进行滚动动作的守门员会降低其髋部负荷。本研究提供的数据补充了生物力学数据库，并有助于制定损伤标准。此类信息对于制定和实施有助于预防髋部损伤的策略是必要的。
