Some people are more flexible than others as defined by individual body flexibility score; this includes sex differences where females are generally more flexible than males.[citation needed] Stretching may not increase range of motion,[citation needed] but rather increase individual stretch tolerance, becoming detrimental to athletic performance.[citation needed] Among the factors these studies measure are capsular mobility, FlexiScore and joint-muscle compliance. Results of research by Witrouw et al.[11] found that: each of which has a different consideration based on individual activity: In activities where stretch-shortening cycles (SSC) are more prevalent, such as sprinting and jumping, the muscle-tendon units need to store and use more elastic energy In activities which do not require as much SSC such as jogging, a more elastic muscle-tendon unit is not needed.[clarification needed] The reason behind conflicting data is claimed to be due to the different levels of observed sports activity. |
