A pair of new studies from the University of Michigan offers an interesting take on how to prevent knee injuries like the ever-common ACL (anterior cruciate ligament) tears. What they’ve found is that the “wrong move” that leads to the injury may result as much from fatigue in your central nervous system as from physical fatigue in the knee or joint itself. That means we may want to change the kinds of preventive exercises we do to focus more on our brains and reflexes. Continue reading “Preventing knee injuries with mental training”

Last year, I had an interesting conversation with Dr. Reed Ferber, who runs the Running Injury Clinic at the University of Calgary. He’s a big believer in the role of hip strength in promoting proper biomechanics — in one seven-month study he performed, 92 percent of the injured runners who reported to his clinic had abnormally weak hip muscles, and 89 percent of them improved with a four- to six-week hip strengthening program. (Read more about his research, and the exercises he recommends, in this Jockology column.)

I mention this in light of a study that researchers at Rush University Medical Center in Chicago are conducting, trying to see if strengthening hip muscles can relieve pain and slow the progression of arthritis in the knees.

The exercises focus on strengthening the hip abductor muscles, such as the gluteus medius, a broad, thick, radiating muscle that helps to stabilize the pelvis during ambulation. In patients with osteoarthritis in the knees, these muscles tend to be weak, causing the pelvis to tilt toward the side of the swing leg when walking, instead of remaining level with the ground, which increases the load on the knee joints. Strengthening these muscles helps the pelvis and the knee remain in better alignment, and thereby lessens the load.

Sounds like the same principles at work — I’m sure Dr. Ferber will be watching carefully to see the results of this study.

[updated to include pictures of how to do the exercise]

The annual meeting of the American Orthopaedic Society for Sports Medicine is taking place right now in Colorado. Among the research being presented is a new approach to “tennis elbow,” which apparently affects three percent of the population. The study took 21 patients and gave them both the standard conservative treatment (stretching, ultrasound, massage, heat and ice), and then split them into two groups for wrist strengthening exercises:

The eccentric training group performed isolated eccentric wrist extensor strengthening using the rubber bar (Flexbar, Akron OH) while the standard treatment group performed isotonic wrist strengthening exercises.

Apparently the fancy rubber bar worked so well that they halted the trial early to let the controls get the good stuff, which is generally a sign that the researchers are seeing a very strong effect. Given how much of a nuisance tennis elbow can be, this seems like good news. The only problem is that I have no idea what an isolated eccentric wrist exercise with a rubber bar looks like. I’ve asked for some further description or diagrams to help clarify, and I’ll post them here when I get them.

Update: I just received a copy of the research paper, along with some pictures to illustrate the exercises. Continue reading “Fixing tennis elbow with a “rubber bar” [updated with pics]”

The July-August issue of Canadian Running is on newsstands now, which means the latest “Science of Running” column is available online. Topics covered: why mental fatigue can slow you down as much as physical fatigue; how a supplement called beta-alanine can boost your sprint finish even at the end of a long race; how running compares to cycling and weight-lifting for building bone strength; what types of music boost performance; and the best pacing strategies for racing in the heat.

Of course, there’s lots of other good stuff in the issue, including (pardon the self-promotion) a feature I wrote on how running has influenced human evolution, and what it means for our current attempts to avoid injury. To whet your appetite, here are the first few paragraphs: Continue reading “Tired brains, sprint supplements, and tunes that make you faster”

Exercise for back pain

The biggest conference in sports science, the annual meeting of the American College of Sports Medicine, wrapped up last week in Seattle. It’ll take a few weeks to sort through the rubble and pull out the worthy new studies, but I figured I’d start with a University of Alberta study on back pain, since it’s something that will afflict about 80 percent of North Americans at some point in their lives.

Researchers took 240 people with chronic lower-back pain, and had them exercise with weights two, three or four days a week, or else not at all. The verdict:

“While it could be assumed that someone with back pain should not be exercising frequently, our findings show that working with weights four days a week provides the greatest amount of pain relief and quality of life,” said Robert Kell, lead author of the study…

Over the course of the 16-week study, the four-a-week group reduced pain by 28 percent, the three-a-week by 18 percent, and the two-a-week by 14 percent. Obviously we’ll need some more details of what, exactly, the exercise program consisted of — but it seems to jive with the general trend towards active recovery rather than immobilization.
