“…A procedure employed in a previous study (13) was used for biomechanical analysis. The video for motion analysis was recorded from four directions with the planting box at the center using four high-speed cameras (GC-LJ20B, JVC, Kanagawa, Japan), recording at a rate of 240 fields/s.…”

Background: Large maximum hip flexion and extension range of motion is considered effective in preventing injury in pole vaulters. Nonetheless, whether the improvement in hip flexion and extension range of motion changes their hip joint angle during pole vaulting remains unclear. Objectives: The present study aimed to clarify the acute effects of intervention for hip flexion and extension range of motion in pole vaulters on the maximum hip joint angle during pole vaulting. Methods: Seventeen male pole vaulters who underwent the same intervention for hip range of motion were included. The maximum hip joint angle during the pole vault from the touchdown of the last step of the run-up to the pole straightening was calculated from videos taken pre- and post-intervention and was subsequently compared. The pole vaulters cleared bungee bars that were set at the height of 90% of their personal best record. Three types of self-massages were used to improve the hip flexion and extension range of motion, and an active straight leg raise exercise was also performed. All intervention programs were completed in approximately 25 min on an experimental day, and all interventions were monitored by the examiner. Results: No significant improvements were observed between pre and post-intervention hip range of motion. The magnitude of change in the range of motion of active hip flexion was significantly correlated with the magnitude of change in the maximum hip flexion angle during pole vaulting pre-and post-intervention (P = 0.002, r = 0.687). Conclusions: Athletes should find ways to improve their active range of motion to prevent injuries and improve their performance. Coaches and athletic trainers should adopt an active range of motion as an indicator to control athlete conditioning.

“…For the experimental trials, the vaulter performed on bungee bars that were set at 90% of their personal best record until the vaulter was able to jump over the bar three times, and those three trials were used for the analytical trials. In this study, a bungee bar was used to ensure safety and reduce the burden on the participant [9]. The mean of the three analyzed trials was used for statistical analysis.…”

“…Motion factors (such as differences in skill level and vaulting) may cause chronic LBP [1], which has not been previously studied. A previous study reported that the maximum hip flexion angle on the TO leg during pole vaulting in the vaulters with lumbar disc degeneration was significantly smaller than that in the vaulters without lumbar disc degeneration [9]. Therefore, if the joint angles of the joints adjacent (such as shoulder or hip) to the lumbar region during pole vaulting are small, there may be increased mobility in the lumbar region.…”

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.
