Under Mourinho, Chelsea became the fifth English team to win back-to-back league championships since the Second World War (2004â05 and 2005â06), in addition to winning an FA Cup (2007) and two League Cups (2005 and 2007).
The Fosbury flop, the most widely used high-jump technique, requires lots of flexibility so the jumper can stay as close to the bar as possible to clear the greatest height. A big back arch allows the jumper to literally wrap herself around the bar before flipping her legs and feet clear.
It is therefore no surprise that this type of stretching is used to improvedynamic flexibility which is what you use when you run and jump. If you do not have sufficient dynamic flexibility to movefreely in those movements then your performance will suffer and you will increase the chances of injury.
