Upper back discomfort following a running session often stems from biomechanical imbalances or insufficient core strength. This soreness manifests as aching or stiffness in the region between the shoulder blades and the base of the neck. An example includes feeling tightness when attempting to rotate the torso after a run.
Addressing this issue is beneficial for maintaining proper posture and efficient running form. A strong and stable upper back supports the shoulders and allows for optimal arm swing. Historically, runners may have overlooked upper body conditioning, focusing primarily on lower body strength and cardiovascular endurance. However, modern training methodologies emphasize the interconnectedness of the entire musculoskeletal system.
