Brief 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.

Outcome Measures

Primary Outcomes (5)

• Muscle Strength

  Muscle Strength: In measuring the muscle strength of the back area, the participant will be provided to take the starting position for the test on the dynamometer (Takkei-Japon) while the knees are flexed. Then, while his/her arms are in extension, his/her back is straight, and his/her body is slightly flexed, he/she will be asked to pull up the dynamometer bar he grasped with his/her hands vertically using his legs at the maximum level. This traction will be repeated three times. The best result will be recorded.

  3 weeks

• Lumbal Area Joint Range of Motion: Hand Finger-Ground Distance (HFGD)

  Hand Finger-Ground Distance (HFGD): Participants will lean forward as much as they can, standing, hands-free, without bending their knees. Lumbar joint range of motion will be found by measuring the distance between the participants' third finger and the ground.

  3 weeks

• Lumbal Area Joint Range of Motion: Modified Schober Test

  Modified Schober Test: With the participants standing in an upright position, a line will be drawn joining the right and left posterior superior iliac spine. From the midpoint of this line, 10 cm up and 5 cm below will be marked, the participants will be asked to lean forward as much as possible without bending their knees, and the distance between the two will be measured again. Lumbal joint range of motion will be obtained by recording the measured value above 15 cm as a result of the modified Schober test.

  3 weeks

• Balance Performance

  Flamingo balance test: Specially prepared balance bench (fifty cm long, four cm high, three cm wide) and timekeeper will be used in the test. The participant will be placed on the balance bench with his dominant foot. Then, the participant will be asked to flex the other knee, pull it towards the hip and hold it with the same hand. After the participant takes the correct position, s/he will get help from the test manager by holding on to the test manager until he/she stabilizes, and the time will start from the moment he/she stabilizes and quits the support. The time will be stopped when the participant's balance is disrupted, that is, when s/he leaves his/her foot, falls from the bench, any part of the body touches the ground, and so on. The total time will be a minute. The number of times the participants are unbalanced during the test (falling etc.) will be counted and recorded as the athletes' scores at the end of the test. Low scores mean better, higher scores mean worse outcome.

  3 weeks

• Pain Intensity

  Pain Intensity: It will be evaluated with a visual analog scale (VAS) numbered equal intervals from 0 to 10 on a 10 cm line, which is used to digitize some values that cannot be measured numerically. 0 means no pain and 10 means unbearable pain. Thus, participants will be asked to mark the intensity of pain they perceive.

Study Arms (2)

Control group

NO INTERVENTION

20 people will be included in the control group. 3 measurements will be taken one week apart in total. Measurements will consist of maximum isometric muscle strength, lumbar range of motion, balance performance, and pain intensity. And it will be evaluated respectively by back dynamometer, hand finger-to-ground distance (HFGD) and Modified Schober test, flamingo balance test, and visual analog scale.

Chiropractic group

EXPERIMENTAL

20 people will be included in the experimental group. Lumbal chiropractic HVLA (High Velocity, Low amplitude: HVLA) spinal manipulation and sacroiliac joint chiropractic HVLA manipulation will be applied 3 times in total with a weekly interval. The maximum isometric muscle strength before and immediately after the application, lumbar joint range of motion, balance performance, and pain intensity will be evaluated respectively by back dynamometer, hand finger-to-ground distance (HFGD), and Modified Schober test, flamingo balance test, and visual analog scale.

Other: Chiropractic Manipulation

Interventions

Chiropractic Manipulation OTHER

Lumbar vertebrae and sacroiliac joints of the participants that have lost their normal joint motion will be detected by static and dynamic palpation techniques. Lumbal Chiropractic HVLA Spinal Manipulation: HVLA manipulation will be applied in the left transverse process of the lumbar vertebra (mammillary process) of the participants whose problem is to the left of the lumbar vertebra. Sacroiliac Chiropractic HVLA Manipulation: Participants who lost normal joint motion in the anterior and superior directions in the left sacroiliac joint will be treated with HVLA manipulation in the left PSIS (Posterior Superior Iliac Spine: PSIS). Participants who have lost normal joint motion in the left sacroiliac joint in the posterior and inferior directions will be applied HVLA manipulation in the left ischial tuberosity. For both applications, it will be positioned in the opposite position for the problems on the right and the application will be made in the opposite position.
