Studies about the benefits of stretching have had mixed results. Some show that stretching helps, while others show that stretching has little if any benefit. The main benefits of stretching are thought to be:
- Improving athletic performance
- Decreasing the risk of activity-based injuries
Stretching can help improve flexibility. And better flexibility may improve your performance in physical activities or decrease your risk of injuries by helping your joints move through their full range of motion. For instance, say your Achilles tendon is tight and lacks flexibility. If you do a lot of hill walking, your foot may not move through its full range of motion. Over time, this can increase your risk of tendinitis or tendinopathy in your Achilles tendon. Stretching your Achilles tendon, though, may improve the range of motion in your ankle. This, in turn, can decrease the risk of microtrauma to your tendon that can lead to overload and injury.
