Erector spinae IMF (left)
Bone and muscle healthIntramuscular fat percentage in the left erector spinae, a group of muscles that straighten and rotate the back.
Increased IMF is associated with muscle quality deterioration and potential functional decline.
Why this matters
Higher levels of intramuscular fat in lower back muscles (erector spinae) indicate deterioration in muscle quality, which can reduce spine stability, increase the risk of injury and correlates with chronic lower back pain. Fat infiltration often develops from prolonged inactivity, lack of exercise, or previous muscle injuries. Unlike subcutaneous fat you can lose through diet, reducing intramuscular fat requires targeted exercise to rebuild muscle quality. This is a research-based wellness measurement for tracking muscle health.
