Effects of Lumbosacral Chiropractic on the Olympic Style Weightlifting Athletes

Athletic Injuries Clinical Trial

Official title: Effects of Lumbosacral Chiropractic Spinal Manipulative Therapy on Muscle Strength, Range of Motion, Balance and Pain in Olympic Style Weightlifting Athletes

Status Completed

Clinical Trial Summary

It is known that low back injuries experienced by weightlifting athletes cause a decrease in performance. The effects of spinal manipulative therapy, which has been found to positively affect performance in various sports, are not known in the Olympic style weightlifting athletes. This study is aimed to investigate the effects of lumbosacral chiropractic spinal manipulative therapy on muscle strength, range of motion, balance, and pain in Olympic style weightlifting athletes.

In this research, 40 male Olympic style weightlifting athletes are planned to take place. Male athletes will be randomly divided into two groups as a control and a treatment group. To the individuals in the treatment group; lumbal region chiropractic high-speed, low amplitude (High Velocity, Low amplitude: HVLA) spinal manipulation and sacroiliac joint chiropractic HVLA manipulation are planned to perform once a week for a total of three weeks. No manipulation will be made to individuals in the treatment group. Before and after the manipulation; the maximum isometric muscular force, the lumbar spine range of motion, balance performance and pain intensity will be evaluated by a back dynamometer, hand finger-ground distance test (HFGD), and Modified Schober test, flamingo balance test, and visual analog scale. SPPS 25 (IBM Corp. Released 2017. IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp.) version will be used to analyze the data.

Clinical Trial Description

There are studies in the literature regarding the positive effect of chiropractic treatment on musculoskeletal injuries. In a study, it is found that the group that received cervical chiropractic manipulation on judo athletes showed a statistically significant (p <0.05) increase in grip strength compared to those who received sham practice. In another study, it is found that a single lumbar spinal manipulation reduced the relative strength difference between the limbs for knee and hip flexion (p <0.05). In another study, it is shown that a single spinal manipulation session increased the muscle strength of the ankle plantar flexor muscles and corticospinal excitability (p <0.05) in elite Taekwondo athletes. Likewise, according to another study, lumbopelvic joint manipulation increased quadriceps activation and strength.

A study claims that young female athletes with talocrural joint dysfunction showed a statistically significant (p <0.05) improvement in vertical jump height after chiropractic manipulation. In addition, in a study investigating the effect of pelvic manipulation on vertical jump height in female university students with functional leg length inequality, it was found that after the intervention, jump height improved significantly only in the pelvic manipulation group compared to pre-intervention height, while improvement in female university students with functional leg length inequality was found to be statistically significant (p <0.05) in both manipulation and stretching groups after the manipulation.

A study showed that chiropractic spinal manipulative therapy can increase hip extension ability in young running athletes (p <0.05). According to a study conducted on football players, it was shown that combined manipulative interventions caused significantly (p <0.05) increases in the range of motion in the lumbar region and sacroiliac joint flexion. In addition, it was reported that the group who received chiropractic manipulation (compared to the group that received sham manipulation) caused a significant increase in kick speed (p <0.05) after the manipulation.

Again, in another research, it is found that an increase in cervical range of motion and a decrease in neck pain with a single cervical HVLA (High Velocity, Low amplitude: HVLA) manipulation (p <0.05) and stated that HVLA manipulation was more effective than mobilization. ;
