Research Reveals Insights on Gluteus Maximus and Health

Sometimes, it’s the less noticed areas of our bodies that can provide significant health insights. A group of researchers from the University of Westminster in the UK has found that the shape of the gluteus maximus muscle in your buttocks can change due to factors like age, gender, lifestyle choices, and certain conditions, including osteoporosis and type 2 diabetes.

They employed advanced MRI technology to create 3D images and identified a distinctive pattern in the gluteus maximus muscle associated with type 2 diabetes. This indicates that muscle shape might actually reflect metabolic differences, rather than just size, as emphasized in their findings.

These revelations were shared at the Radiological Society of North America’s annual meeting in Chicago last December.

What adds depth to this study is that, unlike earlier research focused on muscle size and fat, the 3D imaging specified where changes in muscle occurred.

The gluteus maximus, one of our largest muscles, is essential for metabolic health, according to E. Louise Thomas, Ph.D., a professor of metabolic imaging at the University of Westminster.

Researchers analyzed over 61,000 MRI scans from a substantial health database in the UK, aiming to understand muscle structure further. This data included participants’ physical attributes, demographics, disease markers, medical histories, and lifestyle habits to investigate their correlation with muscle shape over time.

Interestingly, the researchers found that individuals with higher health indicators, such as engaging in vigorous exercise and better hand grip strength, exhibited a healthier shape of the gluteus maximus. Conversely, factors like aging, frailty, and excessive sitting were linked to muscle thinning.

The study concluded that shifts in buttock shape could signal an early decline in function and a drop in metabolism, particularly in people with type 2 diabetes.

Notably, the study found distinct differences between genders: men with type 2 diabetes experienced muscle shrinking, while women had hypertrophy—likely due to fat infiltration in the muscles. This observation indicates that men and women may respond biologically quite differently to the same disease.

Furthermore, men categorized as ‘frail’ demonstrated a more generalized contraction throughout the gluteus maximus, while women experienced a limited impact of frailty.

Importance of Strong Glutes for Overall Health

Tanya Becker, co-founder of Physique 57 in New York, reiterates the importance of strengthening your glutes as an investment in long-term health. While full-body strength training is critical, she points out that the glutes, being the largest muscle group, deserve special focus.

Becker describes the glutes as the body’s “shock absorbers,” protecting the hips, knees, and lower back from undue stress. She notes that larger muscle groups burn more calories and help regulate blood sugar, which is crucial for general health—these muscles often being referred to as the “organ of longevity.”

Strengthening the glutes not only protects major joints but also enhances posture and balance, thereby reducing fall risks and improving mobility.

Becker recommends traditional exercises like squats, lunges, and bridges but acknowledges these may not suit everyone, especially older adults with joint issues. For those cases, she suggests Pilates and barre classes as effective bodyweight training alternatives, accessible to beginners before advancing to weights.

Among her recommended exercises are:

1. Quadruped Leg Lift (strengthens the core and glutes)

Start on your hands and knees, engage your core, and lift one bent or straight leg off the ground. Pulse up and down for 30 to 60 seconds, then switch legs.

2. Clamshell (strengthens gluteus medius)

Lie on your side with knees bent at 90 degrees, raise your top knee away from the lower knee, then lower it back. For a tougher challenge, lift both feet, keeping heels together, and repeat for 30 to 60 seconds on each side.

3. Glute Bridge (strengthens lower back and glutes)

Lie on your back with knees bent and feet flat on the floor a few inches from your hips. Engage your abs, squeeze your glutes, lift your hips to knee height, then lower back down. Avoid straining your neck; aim for 30-60 seconds. Complete three sets with 30 seconds of rest in between.

Anyone starting a new fitness routine should consult a healthcare provider first.
