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.
Flexibility is the range of motion possible around a specific joint or series of articulations. Flexibility is specific to a given joint or movement. A person may not be able to function normally if a joint lacks normal movement. The ability to move a joint through an adequate range of movement is important for daily activities in general as well a sports performance. For example, a sprinter may be handicapped by tight, inelastic hamstring muscles since the ability to flex the hip joint will be limited, thus shortening stride length.
