The flush run
It’s so commonplace for baseball pitchers to go on their “flush run” the day after they throw, believing this slow continuous activity, usually a long jog, will alleviate soreness. Another example is intermittent sports like hockey, soccer, and rugby that perform this sustained exercise in a mythical attempt to recover from their games. The best this activity can offer is a slower athletic performance and a greater injury risk. In order to efficiently perform an exercise for a long period of time, the body must use a shorter and stiffer range of motion. It is why you see a marathon runner using a shorter cycle than the longer stride of a 100 meter sprinter. Yet, this smaller range of motion does nothing to stretch the tight muscles from the preceding game or match. In fact, such shortened movements serve to further impede recovery, specifically through tightening the fascia. Fascia is a thin layer of soft tissue that provides support and protection for muscle, serving as a web that creates the framework for the entire body. Irritation of this fascia causes inflammation, which causes pain and even greater muscle tension. As mentioned previously (see Sparta Point 10/16/09), the most widely used AND effective fascial treatment is to release your IT band, the muscle running down the side of your leg. A cheaper, longer lasting solution to a foam roller, is a thick PVC pipe. Ten repetitions down each leg for this muscle, and others such as the calf, will go a long way to relieving soreness and tightness. Of course the easiest solution to help your fascia is to limit the amount this tissue is irritated outside of your sport. An equally important reason to avoid flush runs is the stimulus of this sustained exercise to your slow twitch fibers. Your body responds to the nature of the challenge; explosive movements recruit fast twitch muscles and slow movements activate the lower force muscles known as slow twitch fibers. Think of your body’s muscles like a pie chart with a certain composition of fast and slow twitch muscles. Every movement you do will target one of these categories more than the other, so choosing the correct recovery exercise is crucial to ensure fast twitch muscle improvement. While we don’t want to be performing too demanding workouts to recover after games, there is a happy medium that allows a full range of motion to alleviate fascia tightness and still stimulate fast twitch muscles. Just grab a barbell and go through a normal resistance training workout, such as squats and overhead presses, but with less weight. An old baseball coach once remarked to me, “that sitting on the couch was probably better than jogging for his players’ speed and pitching velocity.” Maybe he’s right.

  1. Good point about exercise-induced tightening of the fascia, but I’d caution against using PVC pipe or other extra-hard rollers on a regular basis. They’re less effective overall because their smooth hard surface can’t get down in around the muscle attachments where adhesions tends to accumulate, and they can also cause inflammation and tissue damage if you roll too close to bony areas of the body. In my opinion, a high-quality foam roller is your best option. And for the most effective myofascial release, get a RumbleRoller. It costs more, but is definitely worth it.

  2. For someone such as a sprinter would you say that a spin on the road bike would also tighten this Fascia? Or is the extended range of motion actually going to alleviate tightness and help with recovery?

    I’ve gotten into foam rolling and stretching quite a bit this year and find it to be very effective in keeping me loose but questioning the spin as something I could be spending my time on a workout that is more beneficial.

  3. A spin would be detrimental as well, especially due to the tightening of the hip joint from repetitive flexion. If you’re really serious about sprinting, keep your efforts focused there and rolling.
