![]() GM assumes three basic functions, to act as both a local and global stabilizer and to exert force (to perform global movement at the lumbopelvic region) as a global mobilizer. 9 The muscle runs inferiorly and laterally, splitting into two portions, with the superior portion inserting into the iliotibial tract of the fascia lata and the inferior portion inserting at the gluteal tuberosity of the femur. 7, 8 Recent authors have also suggested attachments originating from the gluteus medius fascia, ilium, thoracolumbar fascia, erector spinae aponeurosis, dorsal sacroiliac and sacrotuberous ligaments, as well as the more traditionally known attachments at the sacrum and coccyx. 6 Traditionally, GM was thought to originate at the posterior quarter of the iliac crest, the posterior surface of the sacrum and coccyx, and to the fascia of the lumbar spine. GM is the largest muscle in the human body, 5 accounting for 16% of the total cross-sectional area. This can be used as part of rehabilitation or injury prevention practices as well as athletic performance training.ĪNATOMY AND FUNCTION OF GLUTEUS MAXIMUS MUSCLE AND ITS IMPLICATIONS IN INJURY RISK AND CHRONIC PAIN ![]() This clinical commentary discusses the importance of GM for athletic performance and injury risk factors which contribute to GM dysfunction and then provides evidenced informed approaches to assess and treat GM dysfunction. Despite GMs considerable importance there is little research attempting to translate evidence into practice to support practitioners when faced with ‘sleepy glutes’. ![]() As such, understanding how to assess and treat GM dysfunction is an important aspect of sports science and medicine, as it has relevance for injury prevention, rehabilitation and performance enhancement. It is however, prone to inhibition and weakness which contributes to chronic pain, injury and athletic under-performance. It plays an important role in optimal functioning of the human movement system as well as athletic performance. ![]() The Gluteus Maximus (GM) muscle is the largest and most powerful in the human body. ![]()
