Discus throwing requires correct and safe techniques. This involves a distinct hurling method that involves spinning the body a number of times and letting go a plate-shaped item from the hand out into the air.
All the muscles from the feet, core and shoulders are utilized in discus throwing. Initially, preparing a throw requires using the lower body muscles to increase momentum.
The hip rotator muscles help in compellingly revolving the body together with the hamstrings, quadriceps, gastrocnemius as well as the tibialis anterior. The movement is finished by the pectorals, shoulder and upper arm muscles. The hand and wrist ligaments absorb the energy from these muscles to allow the release of the discus as forcefully as possible.
Common injuries in discus throwing
Glenoid labrum injury
The glenoid labrum is a round tissue fiber linked to the border of the glenoid. In most cases, the glenohumeral ligaments are stressed by repeated overhead throwing in discus throwing.
The strains can occur superiorly or inferiorly depending on whether the injury occur at the upper or lower part of the glenoid socket. The application of ice, rest and strengthening exercises are suggested to achieve full recovery of the injury.
Rotator cuff injury
The rotator cuff is a group of muscles that comprise the shoulder blade. It is responsible for stabilizing the joint and allowing rotational movement. These muscles are susceptible to various injuries such as tears and tendinitis.
Individuals who are regular players of discus might suffer from overuse of these muscles and ligaments which results to pain when the using the shoulder to release the discus. If tendinitis is not properly treated, it increases the risk for serious ruptures that requires extensive rest and rehabilitation.
Ankle sprains
Since discus throwers spins several times before releasing the discus, ankle sprain is likely to occur due to poor technique and putting the ankle in an abnormal position.
The ligaments comprising the ankle joint are ripped or stretched during an ankle sprain. Oftentimes, a snapping or popping sound can be heard that is followed by pain and swelling.
Labral tear of the hip
The labral is a round cartilage that lines the hip socket where the thigh bone is positioned. It is responsible for providing support and cushioning of the joint. Tears are likely to occur among individuals who place repeated strain on the hip joint or engage in movements while using the joint.
