“…Tendon disorders are very common in sports and any anatomical district may be interested depending on the type of sport practiced (Loiacono et al, 2019). For position and role, hip and the surrounding tendons are overstressed and often overloaded, especially in athletes (Schilders et al, 2013): this could lead to the developing of several tendinopathies, among which the differential diagnosis is often complicated (Frizziero et al, 2016). The anatomy of hip is extremely complex, and several muscles interact and contribute to its functioning: flexors (iliopsoas, rectus femoris, pectineus and sartorius), extensors (gluteus maximus and hamstrings -semimembranosus, semitendinosus and biceps femorii), adductors (adductors longus, brevis and magnus, pectineus and gracilis), abductors (gluteus medius, gluteus minimus, piriformis and tensor fascia latae), external rotators (biceps femoris, gluteus maximus, piriformis, assisted by the obturators, gemilli and quadratus femoris) and internal rotators (anterior fibres of gluteus medius and minimus, tensor fascia latae) (Wilson & Furukawa, 2014).…”
