The following Wednesday Workout comes from Dr. Zuzana Rogers, PT, ScD, SCS, COMT, of Anchorage, Alaska. Rogers has been the go-to physical therapist for the U.S. Cross Country Ski Team since 2013 and Alaska Pacific University (APU) Nordic team since 2011.

You are probably training hard…but is your recovery optimal?

As you transition from summer to fall training and the intensity increases, you may start noticing certain tweaks that are happening to your body and the fatigue sets in. But you want to train more than your competitors… Intense training is only a part of the picture. As you get better and training at the edge of human capabilities, what will set you apart for your competition is appropriate recovery. Your body gets stronger and more fit AFTER THE WORKOUT, when it is able to absorb the load you just put it through.

During the past years, literature has been all over the place when recommending the most effective method of recovery after an intense exercise. Recent systematic analysis (Dupuy et al. 2018) places active recovery, massage, compression garments, cold water immersion, contrast water therapy, and cryotherapy as effective methods in reducing exercise-induced DOMS (delayed onset muscle soreness) and fatigue.

So let’s look at them one by one:

1. Active recovery:

Considered a pretty good method to recover after exercise, it helps to clear CK (creatine kinase) after approximately seven minutes of low-intensity exercise, such as a jog or a spin. It does not seem to make you feel less fatigued, but the physiological benefits are there. The effect of active recovery may be explained through enhanced blood flow in muscle tissue, which facilitates the removal of metabolic waste, and may contribute to a reduction in muscle lesions and pain.

How about stretching? If done aggressively, stretching has no positive impact on DOMS. Moreover, some results at <6 h after exercise indicated that aggressive stretching might even produce DOMS. However, if done with the right goal in mind, it can improve the functional range of motion of your joints and optimize the length of the muscles. The muscles work the best when used in their optimal range (this is sport-specific). Overstretched muscles become less efficient in their contractibility, therefore the performance goes down.

Here are my favorite mobility exercises, done to improve crucial areas of restrictions found in cross-country skiers and runners:

2. Massage therapy:  

Massage is a very traditional way to improve recovery after physical exercise both in sports and rehabilitation contexts. It seems to be the most effective method for reducing DOMS and perceived fatigue. It appears to be effective in reducing micro-inflammation of the muscle by decreasing intramuscular edema after exercise. A 20- to 30-minute massage that is performed immediately following or up to two hours after exercise has been shown to effectively reduce DOMS for 24 hours after exercise. It also reduces circulating Cortisol (stress hormone) and increases blood concentration of beta-endorphins (it makes you feel good!).

3. Compression garments:

They are shown to also reduce DOMS when worn after exercise, but to lesser effect than massage therapy. The use of compression garments during exercise as means of preventing DOMS and injuries is still up in the air.

4. Cold water immersion:

Overall fatigue after high intensity training and competition can be improved through the use of cold water immersion (cold water bath). Exposure of 11–15°C over 11–15 min was considered to be the optimal circumstance to obtain a positive impact after exercise to reduce DOMS, but this all depends on the type of exercise and its intensity. Both the level of immersion and the cold temperature of the water may reduce the formation of edema and pain sensation after exhaustive physical exercise.

5. Whole-body cryotherapy:

So far, the evidence in longer term DOMS reduction and post-workout recovery is limited. Cryochambers are cumbersome and costly.

Of course, we cannot forget appropriate rehydration, refuel, nutrition and sleep, but that may be a topic for another piece.

In general, if you are not injured, your training and recovery is straightforward.

Happy training and recovering!
