A person can purchase a helmet in the colors of the Pittsburgh Steelers from the following online stores; NFL Shop, FansEdge, Football Fanatics, and TheFind.
A (gridiron) football helmet typically weighs between two and four kilograms (four to eight pounds) according to various gridiron helmet manufacturers.In this weight is included the face masks which are compulsory at all levels of organised gridiron football. The face mask can account for as much as half of the total mass of a gridiron football helmet, but more typically accounts for around a third of the total.On average, gridiron football helmets are the heaviest form of head protection apart from helmets for such purposes as deep-sea diving. This is because of the thick shells necessary to absorb the energy of the impact such that the headform acceleration exceeds 300g. The shell must also resist penetration of a falling 60 degree conical anvil with specific dimension.
Studies of concussion in contact sports have shown that the risk of sustaining a second concussion is even greater than it was for the first if the person continues to engage in the sport.
A bludgeoning weapon was intended to injure or kill by shock. If it was used properly, it would kill a person in heavy armor by concussion or breaking bones. A blow to a helmet, for example, could break a person's neck without doing much to the helmet itself. If such a weapon had spikes or other sharp protrusions, it could penetrate armor, but often the intention of this was as much to rip the armor off a person as it was to stab the person in it. Clubs, cudgels, maces, morning stars, and flails were all types of bludgeoning weapons.
Concussion.
Due to the potential brain damage incurred from a concussion, concussion victims are kept awake primarily to observe and ensure no brain damage has occured. In situations where it has, death may result from a person sleeping.
If you have concussion, you will have such concussion symptoms as repeated vomiting, rapid breathing, slowing or quickening of the pulse. But all these figures will soon normalize. For most people, blood pressure, quickly getting back to normal, although there are times when it sharply and persistently increased. This is due to not only the trauma, but also high-stress feelings. The body temperature does not change. When a person regains consciousness after concussion it's typical for him such complaints as headache, insomnia, tinnitus, flushing, discomfort, feeling of stuffiness. Note that concussion symptoms can vary in individual cases; it all depends on the structure of the human body. Concussion is largely determined by age-related factors. In infants and young children concussion often occurs without impairment of consciousness. In children younger (preschool) age concussion can occur without loss of consciousness. The general condition improved within 2-3 days.
No, I am very sorry, but it is best not to ice skate when you have a concussion. One person's confusion can mislead them on the ice, and can cause serious injuries to one already with a concussion and those around him or her. This can also damage the actual rink, leading to costly bills and expenses. Unless you want mild injuries, I suggest you avoid ice skating if you have a concussion.
A concussion
The first person to design a bar face mask on a helmet was a sporting goods shop owner named Vernon McMillen in the mid 1930s. It was a rubber covered wire mask that was used with the leather helmets of the day. The sporting goods company Riddell designed the first plastic face mask in 1940 to be used with a plastic helmet that they also designed.
Swedish Ice Hockey champion, Sven Tumba invented the first hockey helmet, called the SPAPS-helmet
A grade 1 concussion can usually be treated with rest and continued observation alone. The person may return to sports activities that same day, but only after examination by a trained professional
