Stretching

As a seasoned Sports Massage Therapist, I regularly find myself in the role of a wellness guide, emphasizing the often underestimated power of stretching. Whether my clients are aiming for peak athletic performance or simply seeking improved flexibility, the message remains consistent. And if you've ever experienced the discomfort of lower back pain after hours at a computer, you're far from alone. It's a familiar scenario for many office warriors. This is where I step in, suggesting a straightforward yet profoundly effective solution: targeting those glutes and hamstrings. In this exploration, I provide a closer look at the importance of these movements and their potential to enhance your well-being.

Typically, athletes engage in stretching before and after physical activities to mitigate the risk of injuries such as muscle strains and tears. However, do these stretching routines genuinely prevent such issues, and if so, how long do the benefits of stretching endure? To address these inquiries, we must delve into the physiological processes that occur within the body during stretching. Broadly speaking, athletes may undertake two types of stretches. Dynamic stretches involve controlled movements that engage various muscles throughout the motion and are typically performed before exercise. On the other hand, static stretches require the individual to maintain a specific position, thus sustaining particular muscles at a fixed length and tension. These stretches are generally carried out post-exercise. Our athlete, for instance, is currently executing a static hamstring stretch, holding the position for a 30-second interval to extend the hamstring beyond its usual range of motion.

Despite the analogy of muscles being stretched like rubber bands, the reality is more intricate. Muscles comprise diverse tissue types that interact to create a complex material. Unlike rubber, which is elastic and reverts to its original shape, muscles exhibit viscoelastic properties. This means that muscle properties change when subjected to stretching. Consider this process in action. During the hamstring stretch, layers of protective tissue encompassing muscle fibers, as well as the tendons linking the muscle to adjacent bones, are tugged. These tissues contain elastic proteins, such as collagen and elastin, enabling slight elongation during the stretching period. At a microscopic level, skeletal muscle fibers consist of millions of sarcomeres— the smallest functional units responsible for muscle contraction. These fibrous proteins can either relax, elongating muscle fibers, or contract, shortening them. This action pulls on tendons and protective tissue, generating the force propelling the body. As these tissues are stretched, their strength is maintained even at extended lengths, enabling the athlete to fully utilise their enhanced range of motion.

In contrast to a rubber band, a muscle's resistance to stretching lessens with each 30-second stretch, allowing athletes to progressively elongate their hamstrings. This heightened flexibility likely reduces the likelihood of specific muscle injuries. However, due to the muscle's elastic nature, this effect dissipates within just 10 minutes without further activity. If exercise follows dynamic stretching (which isn't universally recommended and depends on the sport and individual), it should raise the muscle's temperature and continue elongating it, sustaining the increased flexibility throughout the workout. Yet, once the muscles are at rest, they revert to their prior state. This underscores why static stretching before exercise could sometimes be counterproductive. Furthermore, assuming that stretching for extended durations, such as 20 or 30 minutes, will yield miraculous flexibility is a misconception. Similar to training for a sport, consistent practice is vital for substantial, enduring enhancements.

So, how can you achieve lasting flexibility? In skeletal muscles, improved flexibility stems from the addition of sarcomeres, which enable sustained strength at even greater lengths. The number of sarcomeres in muscles fluctuates based on their frequency of use, making a comprehensive stretching regimen and consistent practice necessary for boosting overall flexibility. Research currently suggests dedicating at least 10 minutes daily for about two months. Because holding a stretch for prolonged periods is unsafe, it's advisable to divide your stretching into multiple sessions. Moreover, frequent stretching induces enduring alterations in the brain. Consistent stretching heightens your pain threshold, enabling progressively greater stretches. Long-term improvements in flexibility translate to enhanced joint range of motion, potentially reducing the risk of short- and long-term muscle injuries.

However, overstretching is possible, as excessively flexible individuals may inadvertently strain their joints. Additionally, stretching isn't universally advantageous for all types of movements, especially those with low incidences of muscle injuries. For instance, long-distance running involves limited joint motion, rendering pre-run stretching unlikely to prevent prevalent running-related injuries. Nevertheless, post-activity stretching, as with running, can aid in the recovery process, minimising muscle soreness and facilitating more consistent training or aiding relaxation after intense sessions.

Ultimately, diverse lifestyles necessitate distinct forms of mobility. A one-size-fits-all stretching regimen remains inadequate to accommodate every scenario.
