摘要
摘要:研究目的:确定患有和不患有慢性腰痛(LBP)的男性撑杆跳运动员在跳高过程中肩、髋和躯干关节角度(上肢和下肢角度)的差异,并研究所有参与者在跳高过程中运动范围(ROM)与同一关节最大角度之间的关系。材料和方法:本横断面研究包括17名男子跳马运动员。根据问卷调查结果将参与者分为两组(慢性腰痛组和对照组)。4台高速摄像机以240赫兹的频率记录了从最后一步着陆到极点直线阶段的过程。这位跳马运动员跳过了蹦极,达到了他个人最好纪录的90%。测量髋关节屈伸、肩部屈伸和直腿抬高的ROM。结果:慢性腰痛组与对照组关节角度无明显差异。相比之下,ROM与髋关节伸展时最大关节角度呈正相关(p = 0.01, r = 0.58)。结论:髋关节活动度不足可能导致撑杆跳时腰椎伸展时的代偿性运动。
Differences in joint angles during pole vaulting between male pole vaulters with and without chronic low back pain
Abstract Study aim: To determine the difference in joint angles of the shoulder, hip, and trunk (angle of the upper torso and lower torso) during vaulting between male pole vaulters with and without chronic low back pain (LBP) and to examine the relationship between the range of motion (ROM) and maximum angle of the same joint during vaulting in all participants. Material and methods: This cross-sectional study included 17 male vaulters. The participants were divided into two groups (chronic LBP and control) based on their questionnaire results. Four high-speed cameras were used to record at 240 Hz from the touchdown of the last step on the run-up to the pole straight phase. The vaulter cleared the bungee bars that were set at 90% of their personal best record. The ROM of hip flexion and extension, shoulder flexion, and straight leg raise were measured. Results: There was no difference in the joint angles between the chronic LBP group and control group. In contrast, there was a significantly positive correlation between ROM and the maximum joint angle during hip extension (p = 0.01, r = 0.58). Conclusions: Insufficient hip ROM may result in compensatory motion in lumbar extension during pole vaulting.
