1. Technological Influences on Human Performance 12.1 Ergonomics

2. study of human-factors engineering, attempts to make the interactions of humans and mechanical objects (desks, chairs, etc.) as efficient as possible and to reduce the strain placed on the user. An ergonomist determines how to alter a mechanical object to fit humans in general and the specific user. Many technological breakthroughs in sport are based on ergonomics. Many sports injuries are a result of repetitive stress (RSI) or cumulative trauma (CTD). Can you name any RSI’s?

9. Speed skating Clap skate invented by Dutch scientists A longer stride is achieved Mocked at first than in Nagano (1998) records were shattered Caused controversy, but the clap skate is now widely accepted

10. Swimming http://www.youtube.com/watch?v=wLBscMz3O5Y FINA banned all body-length swimsuits. The decision was made during the 2009 World Aquatics Championships. The new policy states that men's swimsuits may maximally cover the area from the waist to the knee, and women's counterparts from the shoulder to the knee. They also ruled that the fabric used must be a "textile" or a woven material and that a suit may not have any fastening devices such as a zipper (drawstrings on male jammers are allowed). FINA did not specify what they meant by "textile." The new regulations took effect in January 2010. http://www.youtube.com/watch?v=aTCA9JI5354 Do you agree that these suits are now banned?
