November Research Round-Up: Gluteus Medius Edition

Every month, Chris and I write the S&C Research review service. In this article, Chris has written a preview of the November 2014 edition. This edition comes out on Saturday and covers a range of brand-new research but has a special theme of the gluteus medius. This should be of great interest to the physical therapists!

Does hip angle affect gluteus medius muscle activity in the clamshell and side-lying hip abduction?

The study: Examining the effects of altering hip orientation on gluteus medius and tensor fasciae latae interplay during common non-weight-bearing hip rehabilitation exercises, by Sidorkewicz, Cambridge and McGill in Clinical Biomechanics, 2014

What did the researchers find?

The researchers found that hip flexion angle did not affect the ratio of gluteus medius EMG activity to tensor fasciae latae muscle activity during the clamshell exercise. They also found that hip rotation angle did not affect the ratio of gluteus medius muscle activity to tensor fasciae latae muscle activity during the side-lying hip abduction exercise. Finally, they reported that side-lying clamshell appears to be a superior exercise for achieving minimal tensor fasciae latae muscle activity while still maintaining high levels of gluteus medius activity.

10 Training Tips for the Ladies

It’s no secret that I primarily train women. At the new Glute Lab, there are around 10 ladies who regularly train with me throughout the week, and only 4 men (I try very hard to resist taking on new clients at the moment so I can focus on my PhD). Since I focus on women, I tend to see a lot of things that other trainers might not see. In fact, you’ll be hard-pressed to find anyone out there who pays closer attention to the nuances between gender differences in strength training. Many of the tips below can apply to either sex, but they’re generally more suited for women than men. Here are ten training tips for the ladies, in no particular order of importance.

What’s All the Fuss About EMG?

What’s All the Fuss About EMG?

By Bret Contreras and Andrew Vigotsky

In recent months, the subject of electromyography (EMG) has become somewhat controversial in the online fitness community. In fact, some fitness writers have even gone so far as to call EMG worthless and inherently flawed, but we completely disagree. The backlash against EMG is predictable if you understand the nature of the fitness industry. When new topics, methods, exercises, or systems gain rapid popularity, they tend to get scrutinized to a much greater degree. Several online authors including Bret Contreras and Brad Schoenfeld have been heavily promoting their EMG research and experiments over the past few years, and this has caused various fitness enthusiasts to question the validity of EMG. Questioning is always a good thing, so we encourage discussion pertaining to EMG. However, it is important to be scientifically grounded or else we won’t reach a consensus.
