Researchers have found a correlation between lack of flexibility and performance, all due to a gene that some possess. The idea is that tight muscles, which are more prevalent in individuals with this gene (COL5A1), have an effect on speed and performance because of the physics of energy return. Tight muscles equal improved performance through improved running economy...
Not sure we can call this high quality scientific evidence (small sample size, one population, no repetition of the study, etc)...but I'll say I dislike my tight legs a little less today!
