Effects of running on intervertebral disc height

|January 1, 1990
Summary
Long distance running significantly decreases vertebral column height. Elite runners lost more height during a 9-mile run than during 7.5 hours of static activity, indicating running increases disc fluid loss.
Area of Science:
- Orthopedics
- Sports Medicine
- Biomechanics
Background:
- Vertebral column height naturally decreases daily due to fluid loss from intervertebral discs under compressive loading.
- Varying physical activities alter the rate of disc shrinkage throughout the day.
Purpose of the Study:
- To investigate the correlation between long distance running and increased loss of vertebral column height.
- To quantify the impact of running on spinal disc fluid dynamics.
Main Methods:
- Thirty elite male runners (ages 17-29) participated.
- Vertebral column height was measured morning, pre-run, and post-run after a 9-mile run.
- Paired t-tests were used for statistical analysis.
Main Results:
- Vertebral column height was significantly reduced after the running session.
- A greater amount of height loss occurred during 1 hour of running compared to 7.5 hours of static activity.
- This suggests running accelerates intervertebral disc fluid loss.
Conclusions:
- Long distance running is associated with a significant increase in vertebral column height loss.
- Running imposes a greater compressive load leading to more rapid fluid extrusion from intervertebral discs than static activities.
- These findings highlight the biomechanical impact of high-impact endurance activities on spinal health.

01:27Degenerative Disc Disease I: Introduction
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...
01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
01:23Degenerative Disc Disease ll: Pathophysiology
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
01:17Structural Joints: Cartilaginous Joints
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary or...
