What is the outcome of chronic, long-term stretching protocols according to moderate evidence?

The outcome of chronic, long-term stretching protocols is primarily associated with increased joint range of motion. Regular, consistent stretching helps improve flexibility by elongating the muscle fibers and the connective tissues around the joints. This increase in range of motion can lead to enhanced functional movements and activities, allowing individuals to perform a greater variety of physical tasks with improved efficiency.

While enhanced muscle recovery, improved athletic performance, and time efficiency in injury management might also be benefits associated with stretching in specific contexts, the primary goal and well-documented effect of long-term stretching is the increase in joint range of motion. Therefore, the evidence supports that regular stretching significantly contributes to flexibility improvements over time, making it a foundational practice for athletes and fitness enthusiasts alike.
