Everyone who's physically active knows that it's part of a good workout regimen. It's also very important to stretch properly if you're trying to improve your posture. Unfortunately, most people stretch improperly. Have you been stretching for a long time - years maybe - but seem to be getting less flexible? You'd think that since you've been stretching for so long, you'd be getting more flexible, not tighter. I'll explain why this is happening in the following few pages. 4 Understanding Flexibility Flexibility can be described as the range of motion (ROM) through which a joint moves. It primarily involves the connective tissue surrounding the joints and adjacent musculature. These connective tissues include the joint capsule, ligaments and tendons. It is important to note that the muscle itself is not the primary concern for ROM. Rather, it's the connective tissue which surrounds the individual muscle fiber units (myofibrils). Why be flexible? Because: * a stretched, or elongated muscle is an efficient muscle (you'll have better performance and be less likely to suffer chronic pain) * the tightness of a muscle must be overcome by an earlier and increased contraction of the opposite muscle (example: when running, the quadriceps would have to begin contracting sooner and with more force in order to move a tight hamstring through a complete ROM) 5 * inflexible muscles can, and will, change basic movement mechanics Therefore: * a more efficient muscle is less likely to be injured * less strength is needed to overcome internal resistance; more strength is available for additional work (this results in increased strength and endurance - you'll run faster and jump higher) * abnormal mechanics will strain supporting structures, which can result in injury (example: tight calf muscles will cause the foot to roll in or pronate excessively; this is one of the causes of shin splints) Too often, the attainment of flexibility has been limited to the demonstration of various stretching positions with limited instructions. For example, you'll see a chart with a series of stretching positions illustrated, with instructions to perform these stretches for "30 seconds, relax, then repeat." 6 To more fully understand specific stretching procedures and how to perform them properly, some background information is in order. Once grasped, you'll understand exactly what flexibility is, what specific tissues are involved, and what needs to be accomplished physiologically so that you'll have more permanently flexible muscles. A Breakdown of Stretching Connective tissue is the ultimate concern of any flexibility program. It is the connective tissue that is primarily responsible for the limitations in ROM around a joint. Connective tissue is fibrous protein material that is organized into: * * * * ligaments tendons joint capsules fascial sheaths A muscle is surrounded by an extensive array of connective tissue. The connective tissue (fascial sheath) contributes to limiting joint ROM. 7 The muscle itself is not of primary concern. Muscle is extremely flexible. It's the connective tissue holding the muscle together that needs to be stretched. So what happens when a stretch position is assumed and the tissue is thus put under stress? And what should the goal be in order to increase flexibility? Some background about connective tissue properties will aid your understanding. Specifically, there are two basic properties of connective tissue. They are the elastic property and the plastic property. Elastic Property The elastic property of connective tissue can be likened to a rubber band. When you stretch a rubber band and let go, the rubber band snaps back to its original shape. The same thing happens in the elastic portion of the connective tissue. The change in shape (length) of 8 the tissue is only temporary, since it returns to its original shape after the stretch is removed. Plastic Property The plastic property of connective tissue refers to the elements in the connective tissue that do not recover their original shape after a stretch is removed. This can be compared to what happens when you stretch putty - the shape obtained during stretching becomes a permanent alteration. Connective tissue does not exhibit elastic or plastic properties exclusively. Instead, there is a combination of the two. The ratio of plastic-elastic elements differ according to the type of connective tissue and its function. This combination of properties is referred to as its viscoelastic properties (the flexibility of your tissue is largely inherited; that's why some people don't stretch and are very flexible, while others need to stretch all of the time). So what types of connective tissue property changes are desired - elastic or plastic? 9 Let's review. Elastic properties are temporary; flexibility under this property are only obtained during a stretch. Plastic properties are permanent; flexibility under this property continues after the stretch. Since you want increased flexibility to extend beyond your stretching regimen, you have to increase the plastic property of the connective tissues your stretching. So what protocol will bring about the greatest amount of plastic change? Well there are three elements to consider: * * * the amount of force of your stretch the duration of this force the temperature of the tissue to be stretched In medical annals, it is generally accepted that a slow, steady, even stretch (called static) is much more conducive to gaining flexibility (improving the plastic property) than a short, intense stretch (called ballistic). A short, intense, bouncy stretch applied to a cold, 10 stiff muscle is counterproductive. It can: * strain or tear a muscle and/or connective tissue * initiate "stretch reflex," where a muscle quickly contracts as a result of a violent stretch (often causing a muscle spasm) Structural damage results from any type of stretching, but maximal damage occurs when a large force is applied to a "cold" muscle. Therefore, it make sense to follow a program that will give maximal optimal results and minimal negative results. With all this in mind, what you want to do is apply low tension force over a long period of time to a warmed up muscle. This results in plastic changes with minimal structural damage. Now that a proper protocol has been established, I anticipate you have the following questions: Q: What is low tension? How do you know when to stop pushing? 11 A: Well, any force that causes pain is too much. The body uses pain as an indicator that the affected area has reached its physiological limits. Pain indicates that damage is being done. Therefore, you should feel tension during your stretch, but no pain. Q: How long is a long period of time? A: A stretching period of three to five minutes per muscle or muscle group should be sufficient. Some individuals may require a little more, while some a little less (when recovering from an injury, stretching several times a day may be necessary). What is a warmed-up muscle? A: A working muscle generates heat. As heat increases, so does the temperature in the muscle. Sub-maximal exercise (enough to break a sweat) should be done prior to stretching (a brief jog, calisthenics, a few minutes on a stationary bike, etc.). Increased muscle temperature enhances plastic changes. 12 Summary to Increasing Flexibility 1. Do some light warm-up exercises to increase tissue temperature before stretching - warm muscles stretch better. 2. Assume a comfortable position that can be maintained for the duration of the stretch. 3. There should be no pain in the muscle being stretched - pain=injury (forget "no pain, no gain" - it doesn't apply here). 4. Hold the stretch position for a minimum of three minutes (preferably five) continuously. 5. Individuals with specific flexibility problems should stretch before and after their activity. That's it! If you follow this stretching protocol, you'll definitely improve your flexibility. As a result, you'll have better performance and a lower risk of injury and headaches- in other words you'll more fully enjoy your workout activity and workaday life. *** One final note. Yes, three to five minutes per stretch will seem like a long time, especially at first. 13 However, you can find comfort in the fact that after you obtain increased flexibility, you won't have to stretch as often. 14
