“…Although generally acknowledged in anatomical texts (Williams et al, ; Sinnatamby, ), the fascial attachment has not previously been quantified. Fascicles attaching to the TLF are located in the region in which EMG activity of GMax is typically recorded (Noe et al, ; Mooney et al, ; Souza et al, ; Hungerford et al, ) and their level corresponds with that at which pelvic belts are placed (Vleeming et al, ) to brace the SIJ for relief of pregnancy‐related pelvic girdle pain (Mens et al, ).…”

Anatomy and biomechanics of gluteus maximus and the thoracolumbar fascia at the sacroiliac joint

Biomechanical models predict that recruitment of gluteus maximus (GMax) will exert a compressive force across the sacroiliac joint (SIJ), yet this muscle requires morphologic assessment. The aims of this study were to document GMax's proximal attachments and assess their capacity to generate forces including compressive force at the SIJ. In 11 embalmed cadaver limbs, attachments of GMax crossing the SIJ were dissected and their fascicle orientation, length and attachment volume documented. The physiological cross-sectional area (PCSA) of each attachment was calculated along with its estimated maximum force at the SIJ and lumbar spine. GMax fascicles originated from the gluteus medius fascia, ilium, thoracolumbar fascia, erector spinae aponeurosis, sacrum, coccyx, dorsal sacroiliac and sacrotuberous ligaments in all specimens. Their mean fascicle orientation ranged from 32 to 45° below horizontal and mean length from 11 to 18 cm. The mean total PCSA of GMax was 26 cm(2) (range 16-36), of which 70% crossed the SIJ. The average maximum force predicted to be generated by GMax's total attachments crossing each SIJ was 891 N (range 572-1,215), of which 70% (702 N: range 450-1,009) could act perpendicular to the plane of the SIJ. The capacity of GMax to generate an extensor moment at lower lumbar segments was estimated at 4 Nm (range 2-9.5). GMax may generate compressive forces at the SIJ through its bony and fibrous attachments. These may assist effective load transfer between lower limbs and trunk.

SUMMARY The human gluteus maximus is a distinctive muscle in terms of size, anatomy and function compared to apes and other non-human primates. Here we employ electromyographic and kinematic analyses of human subjects to test the hypothesis that the human gluteus maximus plays a more important role in running than walking. The results indicate that the gluteus maximus is mostly quiescent with low levels of activity during level and uphill walking, but increases substantially in activity and alters its timing with respect to speed during running. The major functions of the gluteus maximus during running are to control flexion of the trunk on the stance-side and to decelerate the swing leg; contractions of the stance-side gluteus maximus may also help to control flexion of the hip and to extend the thigh. Evidence for when the gluteus maximus became enlarged in human evolution is equivocal, but the muscle's minimal functional role during walking supports the hypothesis that enlargement of the gluteus maximus was likely important in the evolution of hominid running capabilities.

“…The findings of trunk electromyographic (EMG) amplitudes during the flexion and extension movements used daily in standing positions have been reported in a healthy population (Bankoff et al, 2000;Dickey et al, 2003;Gupta, 2001;Kaigle et al, 1998;Kuriyama and Ito, 2005;Larivière et al, 2000;Leinonen et al, 2000;Mathieu and Fortin, 2000;Marras and Mirka, 1992;Mirka et al, 1997;Neblett et al, 2003;Olson et al, 2004;Olson et al, 2006;Paquet et al, 1994;Shirado et al, 1995;Takahashi et al, 2006;Wolf et al, 1979). Extensive research was also performed on muscle fatigability (Kankaanpää et al, 2005;Kankaanpää et al, 1997;Lee et al, 1996;Roy et al, 1989;Sparto et al, 1999;Van Dieën et al, 2003) and muscle activation during different lifting movements (Arjmand and Shirazi-Adl, 2005;Bonato et al, 2003;Cresswell and Thorstensson, 1994;Gagnon et al, 2001;Granata and Marras, 1995;Kingma et al, 2004;Lee and Lee, 2002;Noe et al, 1992;Potvin et al, 1991;Roy et al, 1998;Takahashi et al, 2006). In training exercises, muscle function was analyzed in a standing position using loads in the hands (Arjmand and Shirazi-Adl, 2006;Peach et al, 1998) and resistance from a device …”
