Sports equipment

For instance, the use of a football dates back to ancient China, between the Warring States period (476–221 BC) and the Han Dynasty (220 AD).

This is due to the fact that the equipment is more efficient, lighter and stronger, thus forming a biomechanical system that is interacting with the athlete.

[7] Since the massive adoption of wearable, new sport equipment tend to be electronics and connected to deliver data performances.

Standards and monitoring processes apply in certain industries aimed at the elimination of child labour in the manufacturing of sports goods.

One example would be the Atlanta Agreement of 1997 in relation to child labour in the football-making industry in Pakistan.

In some games, such as association football, hockey and water polo, the object is to pass the ball or puck between the posts below the crossbar.

Athletes wear ice skates in most ice-based sports, although there are exceptions such as broomball and curling.

Athletes with limb differences (such as those in the Paralympics) may use extremity prostheses, such as the Flex-Foot Cheetah running blade.

As part of the uniform, athletes may wear jerseys; they may also be called shirts, sweaters in ice hockey or guernseys in Australian rules football.

Small vehicles with flatbeds are often used to carry injured athletes off the field, most commonly in American football.
