Hammer throw

 ( Individual Sports ) 

While the men's hammer throw has been part of the Olympics since 1900, the International Association of Athletics Federations did not start ratifying women's marks until 1995. Women's hammer throw was first included in the Olympics at the 2000 summer games in Sydney, Australia, after having been included in the World Championships a year earlier.

The throwing motion starts with the thrower swinging the hammer back-and-forth about two times to generate momentum. The thrower then makes three, four or (rarely) five full rotations using a complex heel-toe foot movement, spinning the hammer in a circular path and increasing its angular velocity with each rotation. Rather than spinning the hammer horizontally, it is instead spun in a plane that angles up towards the direction in which it will be launched. The thrower releases the hammer as its velocity is upward and toward the target.

Throws are made from a throwing circle. The thrower is not allowed to step outside the throwing circle before the hammer has landed and may only enter and exit from the rear of the throwing circle. The hammer must land within a 34.92º throwing circular sector that is centered on the throwing circle. The sector angle was chosen because it provides a sector whose bounds are easy to measure and lay out on a field (10 metres out from the center of the ring, 6 metres across). A violation of the rules results in a foul and the throw not being counted.

the men's hammer world record is held by [[Yuriy Sedykh]], who threw  at the 1986 European Athletics Championships in [[Stuttgart]], [[West Germany]] on 30 August.  The world record for the women's hammer is held by Anita Włodarczyk, who threw  during the Kamila Skolimowska Memorial on 28 August 2016. Sedykh's 1986 world record has been noted for its longevity, and for dating from "a time when track and field was starting to realize the scale of performance-enhancing drug use" (AP). According to Russian doping whistleblower Grigory Rodchenkov, Sedykh was a heavy user of [[steroids|Steroid]], which Sedykh denied.
     

The throwing distance depends on the velocity and height at which the hammer is released, but also on other factors that are not under the athlete's control. In particular, Earth's rotation affects it via the location's latitude (due to the centrifugal force, the hammer will fly a bit further in a location closer to the equator) and to a lesser extent also via the throw's azimuth (i.e. its compass direction, due to Coriolis force). According to a 2023 study, such effects are large enough that the top 20 world-record rankings for both men and women at the time could somewhat change if they were adjusted for latitude and azimuth.
