The men's hammer weighs and the women's weighs , with the wire in either case no more than in length. 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 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, which Sedykh denied. 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 forces). 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. == Safety issues ==
