SPEED

Speed is defined in the video below as the ability of an athlete and/or muscle fibre to produce force as rapidly as possible, which as is discussed can result in movements that visually appear "fast" (i.e. sprinting) but can also result in movements that appear "slow" (i.e. landing from a jump). Whilst there is significant overlap between the neural and muscular factors responsible for speed and strength, there are also some significant differences, such as the inclusion of tendon specific properties and the opposite relationship with pennation angle/muscle fibre length. The video below explores this content in detail, whilst also discussing the requirements for speed training.
