Which of the following is a critical factor for managing low back pain, according to exercise physiology?

Core muscle endurance is recognized as a critical factor in managing low back pain because it plays a vital role in stabilizing the spine and maintaining proper posture during daily activities. The core muscles, which include the abdominals, obliques, and lower back muscles, help support the spinal column and absorb forces during movement. When these muscles are weak or fatigued, there is an increased risk of injury and pain in the lower back. Strengthening and enhancing the endurance of these muscles can improve overall stability and reduce the likelihood of back pain episodes. This focus on core endurance is supported by research indicating that individuals with stronger core muscles generally experience less discomfort and improved functionality in relation to their lower back.

In contrast, while running daily might provide cardiovascular benefits, it may not specifically address the muscular endurance necessary for spinal support. High-intensity interval training, while effective for cardiovascular conditioning, may not prioritize core stability to the extent needed for those suffering from low back issues. Flexibility exercises can aid in maintaining range of motion but do not directly focus on the core endurance aspect that is crucial for managing low back pain effectively.
