A toned gluteus muscle is no doubt one of the hallmarks of fitness and sexiness. But how does having a nice butt help us in movements such as running?
Frédéric Delavier explains in his book Women’s Strength Training Anatomy that in the human being, the gluteus maximus, one of the muscles that makes up the hip extensor muscles, does not play a significant role in gait. But as soon as the effort increases to walking fast or running, the gluteus maximus becomes engaged to extend the hip energetically and straighten the torso.
How much do we need the gluteus muscle when you want to sprint? A lot!
A study “Effect of Running Speed on Lower Limb Joint Kinetics,” published in the Medicine & Science in Sports & Exercise Journal showed the hip extensors and knee flexor muscles (gluteus and hamstrings) demonstrated the most increase in biomechanical load with faster running.
