Introduction
This research study aimed to demonstrate the effects of strengthening the lumbar extensor muscles through full range-of-motion exercises. The study included several subjects who participated in the tests throughout the duration of the study.
Summary
Low back pain is an incredibly common complaint seen by medical professionals and has been for ages. The origin of most low back pain is from a weakness in the muscles in the lumbar area of the spine. Due to the muscular origin of the issue, medical professionals are emphasizing the importance of muscle strengthening through resistance training. By prioritizing good muscular health initially, patients can reduce and prevent pain and injury altogether.
One hundred thirty-six (136) subjects were included in this study. Every subject was healthy and had no history of back problems or other injuries. The subjects tested on 3 different days with a few days in between each test day to allow subjects to rest. Isometric lumbar extension strength was measured during each test day. The tests were conducted using the MedX Lumbar Extension machine. In order to strengthen the lumbar extensor muscles, the pelvis must be stabilized throughout testing. By the end of the study, researchers were able to make an accurate conclusion with the support of their data.
After the three days of testing, researchers were able to conclude that isometric torque increased for the subjects. This demonstrates the efficacy of using resistance training through full range of motion exercises to increase strength in the lumbar extensor muscles. The success of the MedX Lumbar Extension machine also proves the importance of pelvic stabilization when strengthening the lumbar region of the spine. The isometric torque for males and females increased at varying degrees of flexion concluding that the study was accurate.
