Although static stretches were commonly recommended in the past, there is overwhelming evidence to refute the use of static stretches as part of your warm-up activity. Previously, static stretches were thought to increase the actual length of muscle fibers, improve athletic performance, and reduce the risk of injuries if they were performed prior to vigorous activity, but evidence does not support these long-standing claims. Despite the current claims regarding problems associated with these types of stretches, static stretching continues to be incorporated into many warm-up regimens, and they are still recommended by many sports and health professionals to help prevent injuries. This leads to the next question—when are static stretches useful, and how are they helpful?
Understanding When to Perform Static Stretches
Static stretches can be useful as part of your cool-down routine or part of a rehabilitation program to improve recovery from an injury or enhance your flexibility. If you are dealing with an injury, the stimulation from a static stretch may help smoothen rough scar tissue and promote heightened tensile strength in tissues as they heal. In addition, static stretching may assist recovery from a specific injury by allowing you to tolerate greater ranges of movement over time. The same improvement may occur if you are trying to increase your flexibility. Interestingly, although it may feel like you are increasing the length of your muscle fibers and tendons when you hold a position statically, current evidence suggests that this may not be the case. The improvement in range of motion that is often observed over time is not actually due to increased muscle fiber length but may be attributed to a newfound ability to tolerate the stretch sensation at further end points.
Here are some important points to remember when performing static stretches:
- If the purpose of stretching is to increase flexibility, be sure to stretch while your muscles are still warm.
- Slowly stretch your muscles to the end of their range of motion. You will feel slight resistance in your muscles, but you should never feel pain during a stretch.
- Hold the stretch in a static position. Do not bounce.
- Maintain each stretch for about 20-30 seconds. Repeat each stretch 2-3 times.
Another key point to remember is that static stretching after exercise has not been shown to prevent the post-exercise soreness that may develop 1-2 days after an intense exercise session. Warming up as recommended may have a small effect on how sore you feel after a couple of days, but the best way to reduce this soreness is to perform static stretches slowly and progressively. This means that you should gradually increase your workout intensity over a specific time frame and maintain a good intensity to prevent fluctuations from occurring, as this may lead to recurring muscle soreness.
