Have you ever run or walked in a marathon, half marathon, or other endurance race and become so tense that your stride length became shorter than normal?
This stride shortening comes from being too tense. And it can be very frustrating because you must increase your cadence to maintain the same pace. But increasing your cadence can make you tenser, which can lead to further shortening of your stride.
In contrast, have you ever watched a track race -- say, a 100-meter sprint -- in slow motion and noticed this about the winner of the race?
- The winner's face was relaxed and pliable, almost fluttering in the wind.
- The winner's head was erect and relaxed, with no tension in the neck -- at least not until perhaps the very end of the race, when the winner may have had to stretch his or her neck across the finish line.
- The winner's hands were relaxed, not tense or tight.
If this degree of relaxation is important for elite sprinters, who race for under ten seconds at a time, then it should make sense to you that this degree of relaxation -- in other words, lack of tenseness -- is important, too, for endurance runners and walkers, who race for up to several hours at a time.
A 1999 study of sub-elite endurance runners published by researchers at University of Otago, Dunedin, New Zealand, in Medicine and Science in Sports and Exercise concluded that these runners could improve their running economy by using relaxation techniques involving biofeedback of heart rate, ventilation, and VO2 -- all while running at VO2submax.
- "Running economy" is measured by how much oxygen is required to run at a given speed, with a decreasing requirement for oxygen indicating an increasing running economy.
- "Heart rate" (HR) is measured in beats per minute and can be obtained while racing in a couple of ways: by wearing a heart-rate monitor (such as a strap around the chest that wirelessly communicates with a wrist unit that displays heart rate), or by counting the number of beats in six seconds at the pulse point on the wrist and then multiplying by ten.
- "Ventilation" -- also known by physiologists as "ventilatory volume" (VE) -- actually refers to a ventilation rate, usually measured in liters per minute, and equals the product of "ventilatory frequency" (Vf), measured in breaths per minute, and "tidal volume" (TV), usually measured in liters per breath.
- "VO2" is the measure of the volume of oxygen uptake by the body in one minute.
- "VO2max" refers to the maximal volume of oxygen that can be consumed in one minute during maximal effort (exhaustive exercise), and it can be increased with the right kind of training.
- "VO2submax" refers to a rate of oxygen consumption that is less than VO2max.
Given that the New Zealand study was performed on a treadmill in a lab on runners with gear attached to them to measure heart rate, etc., how can you apply the results of this study -- as well as your own slow-motion analysis of sprinters -- to your own running or walking out on the road or trail in an endurance race?
First, recognize that you can use your mind to relax during an endurance race.
Second, appreciate that you must pay attention to certain physiological factors that are indicative of your degree of relaxation:
- Heart rate
- Breathing
- Tenseness in face, neck, and hands
Third, monitor these physiological factors in your endurance race so that you can mentally drive them in the direction of greater relaxation. And you can become good at this by learning and practicing biofeedback-based relaxation while stationary.
