The Benefits Of Stretching

In P.E. class you probably learned to stretch before engaging in physical activity. People stretch for different reasons, most common of all to reduce injury. Currently, most experts agree that flexibility should be considered a vital component to a well-rounded, healthy lifestyle. Stretching is defined as the application of force to musculotendinous structures in order to achieve change in length, usually for improving range of motion (ROM), and reducing stiffness or soreness. Lots of debate surrounds the significant benefits of stretching or lack thereof. Arguments for stretching cite postural benefits leading to better general health and in addition better form when performing in the gym. However, studies have found a decrease in performance

Stretching may also help manage stress of daily living. Adequate ROM is considered to be important because it may be involved in long-term injury prevention. Those with poor flexibility may risk exceeding the extensibility limits of the musculoskeletal unit. Stretching could also play an important role in maintaining flexibility, which declines with age. One study found joint ROM is improved transiently and chronically after flexibility exercise after approximately 3-4 weeks of stretching 2-3 times per week. Unfortunately, stretching may be lacking in too many ways. Stretching is contraindicated in the recovery process and found to decrease blood flow, capillary region oxygenation, and velocity of red blood cells contrary to popular belief. Research has found no positive effect on muscle soreness relief (DOMS). Furthermore, stretching, whether conducted before, after, or before and after exercise, does not produce clinically important reductions in muscle soreness. No studies have been able to consistently link regular flexibility exercise and reduction in musuclotendinous injuries, or prevention of lower back pain. Additionally, muscle strength and muscle power have been shown to decrease by 5.5% and 2%, respectively, when holding a stretch longer than 30 seconds. Therefore, static stretching before a workout may be counterproductive. There is no agreement in the scientific literature on whether static stretching prior to endurance exercise is helpful, though, it’s theorized that greater flexibility does impair performance in sports where a high degree of flexibility isn’t required. In conclusion, more evidence is needed to analyze the effect of stretching duration, and how different stretches affect muscle performance. Current consensus states major flexibility exercise programs should come after resistance
