Mike Boyle describes foam roller work best:
Ready to Roll
Training & Conditioning, 16.9, December 2006, http://www.momentummedia.com/articles/tc/tc1609/readyroll.htm
A decade ago, strength coaches and athletic trainers would have looked quizzically at a 36-inch long cylindrical piece of foam and wondered, “What is that for?” Today, nearly every athletic training room and most strength and conditioning facilities contain an array of foam rollers of different lengths and consistencies.
What happened to bring foam rollers into prominence? The change has been in our attitude toward massage therapy. We have been slowly moving away from an injury care mode of isokinetics and electronics to more European-inspired processes that focus on hands-on soft tissue care. We now realize that techniques like massage, Muscle Activation (MAT), and Active Release Therapy (ART) can work wonders for sore or injured athlete.
What does all this have to do with foam rollers? As coaches and athletic trainers watched elite-level athletes experience success from various soft tissue techniques, the obvious question arose: How can I make massage available to large groups of athletes at a reasonable cost? Enter the foam roller.
Essentially, foam rollers are the poor man’s massage therapist. They provide soft tissue work to the masses in any setting. But you need to know their nuances to get the most out of them.
What, How & When
A foam roller is simply a cylindrical piece of extruded hard-celled foam. Think swimming pool noodles, but a little more dense and larger in diameter. They usually come in one-foot or three-foot lengths. I find the three-foot model works better, but it obviously takes up more space.
The use of foam rollers has progressed in many circles from an accupressure approach to self-massage, which I’ve found to be more effective. The roller is now usually used to apply longer more sweeping strokes to the long muscle groups like the calves, adductors, and quadriceps, and small directed force to areas like the TFL, hip rotators, and glute medius, as well as back, lats, and shoulders.
Athletes are instructed to use the roller to search for tender areas or trigger points and to roll these areas to decrease density and over-activity of the muscle. With a little direction on where to look, most athletes easily find the tender spots on their own. However, they may need some instruction on the positioning of the roller, such as parallel, perpendicular, or 45 degrees, depending on the muscle.
The feel of the roller and intensity of the self-massage should be properly geared to the age, comfort, and fitness level of the athlete. This is one of the plusses of having the athlete roll themselves-they can control the intensity with their own body weight.
There is no universal agreement on when to roll, how often to roll, or how long to roll, but generally, techniques are used both before and after a workout. Foam rolling prior to a workout can help decrease muscle density and promote a better warmup. Rolling after a workout may help muscles recover from strenuous exercise.
I prefer that my individuals roll both before and after exercise, due to the benefits of the roller.
One of the nice things about using the foam roller is that it can be done on a daily basis. In fact, in their book, The Trigger Point Therapy Workbook, Clair Davies and Amber Davies recommend trigger point work up to 12 times a day in situations of acute pain.
So, if you are curious about foam rolling, here is a video guideline for a basic foam rolling routine.
