What is kyphosis characterized by?

Kyphosis is characterized by a posterior curve of the spine, specifically an exaggerated rounding in the upper back, which can give the appearance of a hunchback. This condition results in a forward head posture and can lead to discomfort or pain in some individuals. Recognizing the distinct curvature is essential in understanding how it affects posture and biomechanics, which can influence running form and performance.

In contrast, the other options describe different spinal conditions: an anterior curve typically refers to lordosis, where the lumbar region has an abnormal inward curve; having no curve at all suggests a neutral or straight spine, which is not indicative of kyphosis; and a lateral curve describes scoliosis, another spinal deformity characterized by a sideways curvature. Understanding the definition and implications of kyphosis is crucial for coaches, especially when addressing posture-related concerns in runners.
