What is a hammer throw in Ultimate Frisbee?
A hammer is an advanced frisbee throw that goes upside down and is thrown overhand. Hammers are bending throws which means the aim has to be adjusted for, so it bends into the target just like all other bending throws.
What muscles are used in hammer throw?
Hammer throw demands excess strength of hamstrings, thighs, and hips.
What is a throwing circle made of?
Historically throwing circles have been constructed of standard concrete mix which has been the same as the mix used to set the throwing rim. This has ultimately led to a wide range of differing throwing surfaces which has created problems for throwers when dry as they are too grippy and when the top surface has been worn shiny pebbles are exposed causing the circle to become slippery and lethal when wet.
How to mount a circle in a concrete hole?
This provides an easy method of aligning and shuttering the hole in preparation for pouring the concrete. The corners of the square should be aligned through the centre line of the sector this also forms the centre line of the circle perpendicular to the centre line of the sector on which the boundary lines marking the front half of the circle can be painted. The size of the square hole should be 2.8 m minimum across the sides this allows for 25mm shuttering boards and maintains 100mm distance between the rim of the circle and the edge of the concrete at its minimum points. 1.7
How to make a shutter for a circle?
Shuttering for circle should be constructed using solid planks of wood. This provides a clean edge to tarmac or pave up to once the shuttering is removed. Two lengths of the timber should be cut to 2.7m in length and two lengths should be slightly longer around 2.8m. The 2.7m planks can then be nailed inside the longer planks leaving a slight overhang at each end of the longer planks. This allows for a stake to be driven into the ground in the corner to provide a solid fixing and a stable shuttering. Ensure the shuttering is square before mounting in the hole. This can be achieved using the 3:4:5 rule. Measure from one corner 90cm and mark the top edge of the shuttering. Measure from the same corner along the adjoining plank 120cm the distance between the two marks across the diagonal should be 150cm. Adjust the box until this is achieved. Nail a lathe across the corners to hold the box square. Leave the nail heads protruding slightly to allow easy removal once the shuttering is located in position. A further check of squareness can be achieved by measuring corner to corner across the diagonal, these two lengths should be the same distance approx 3.82m.
What happens if you have poor circle quality?
Poor circle quality produces substandard performance but also increases risk of athletes falling and injuring themselves, aborted throws increasing risk to officials, and long term skeletal joint damage caused by the increased torque produced on knees, hips and lower back of the athletes.

Diameter
A high school discus ring has a diameter of 2.5 m, which translates to 8 feet and 2.5 inches. This is larger than a shot-put ring, which is 7 feet in diameter. The circle on high school discus rings must either have a plastic or metal band that rises 3/4 of an inch over the circle’s level, or a 2-inch-wide painted line.
Throwing Sector
The throwing sector size for the discus ring is 34.92 degrees. Prior to 2006, the National Federation of State High School Associations allowed the throwing sector to measure up to 40 degrees. Tighter sectors require athletes to have more control during their throws.
Cage
Starting in 1993, the National Federation of High Schools required that discus rings have a fenced discus cage positioned over them. Typical fences are 10 to 14 feet tall, with a maximum front opening of 24 feet. In college, the fence must be a minimum of 13.12 feet high, and the front opening 26.8 feet wide.
Slope
The percentage of slope from the throwing sector can be no more than 1 percent. College rules are stricter, allowing only 0.1 percent slope.
What is a throwing circle made of?
The throwing circle is made of band iron, steel or other suitable material, the top of which is flush with the ground outside or the synthetic surface or concrete surround. The interior of the circle is constructed of concrete and must not be slippery.
What is the difference between a discus throw and a hammer throw?
The facility for discus throw, near the 1500m start, is usually combined with a facility for hammer throw.Discus-throw-circle-facility The only difference is the diameter of the throwing circle is 2.50m for discus throw and 2.135m for hammer throw. The protective cage must meet the more stringent requirements for hammer throwing. If two separate discus and hammer circles are placed within the hammer protective cage then the discus throw circle is the circle closer to the landing sector.
Why do you throw hammer and discus from cages?
Hammer and discus must only be thrown from an enclosure or cage to ensure the safety of spectators, officials and athletes. Cages specified in the manual are intended for use in major stadia in high class competition when the event takes place outside the arena with spectators present or when the event takes place in the arena and other events are taking place at the same time. Simpler and smaller cages may be adequate for competition of lower standard and for well regulated training facilities. Further information is available from section 6.3.2 of the Manual.
How far apart are sector lines?
The length of the sector is 100m. At this distance the inner edges of the sector lines are 50m apart. The marking of the sector lines extends to a distance appropriate to the competition.
How wide is a runway throwing arc?
If not marked with paint, it must be installed flush with the surface of the runway.#N#The throwing arc is 0.07m wide, white and curved with a radius of 8m from the centre point in the middle of the runway, in the throwing direction. It is advisable that the centre point is marked with a synthetic plug of a different colour to the surface, with a diameter and surface thickness of 20mm‑30mm. Lines are drawn from the extremities of the arc at right angles to the parallel lines marking the runway. These lines are white, 0.75m in length and 0.07m wide.
Is a concrete circle smoother than a discus?
The circle for the hammer throw is slightly smaller than the discus throw. The surface finish to the concrete circle is slightly smoother for hammer throwing than for discus throwing. When a circle is used for both discus and hammer throwing a compromise finish is required. See section 2.4.2.2 of the Manual for further information.
Can you throw a discus and hammer from a cage?
Frequently discus and hammer are thrown from a combined facility. In those instances the higher standards required for hammer throwing apply to the protective cage design. To provide greater safety it is desirable to extend the netting on the side of the cage nearer to the track further than 7m from the centre of the circle and/or increase the height of the netting for the last 2m.
