Cover Story: Gastrocnemius medialis muscle architecture and ankle joint range of motion were compared between flexibility-trained and not-trained female child athletes aged 8–10 years. At rest, the two groups displayed similar gastrocnemius medialis architecture; during stretching, flexibility-trained athletes displayed greater fascicle elongation at the middle and the distal part of the muscle, and greater muscle–tendon junction displacement compared with athletes not trained in flexibility. Ankle joint range of motion during dorsiflexion was correlated with fascicle elongation at the distal part of gastrocnemius medialis, and muscle–tendon junction displacement. These findings indicate that from an early age, non-uniform adaptations occur along the gastrocnemius muscle length that depend on training history and are evident only during stretching.
