Shoulder Pads/Equiptment

The shoulder pads consist of a hard plastic outer shell with shock-absorbing foam padding underneath. The pads fit over the shoulders and the chest and rib area, and are secured with various snaps and buckles. Shoulder pads give football players their typical "broad-shouldered" look, and are fitted to an adult player by measuring across the player's back from shoulder blade to shoulder blade with a soft cloth measuring tape and then adding 1/2 inch. For comfort, shoulder pads are sometimes worn in conjunction with a shoulder pads cushion of foam rubber over a cotton half-tee. Shoulder pads accomplish two things for a football player: (1) they absorb some of the shock of impact through deformation. The pads at the shoulders are strung on tight webbing and deform on impact, and (2) they distribute the shock through a larger area so there is less pressure at the point of impact. Various styles exist for different positions played. Pads for a quarterback are lightweight and offer freedom of movement. Pads for linemen are designed with few flaps and epaulets, thus reducing the opportunity for being grabbed by the opposition. Some football teams stock as many as 12 different styles (essentially one style for every position), with four different sizes per style. A number of custom fitting and padding options are also available, depending on each player's body type and injuries. At the discretion of the player, team physician, or equipment manager, Velcro is sometimes used to attach additional pads to build up protection or to take pressure off an injury by bridging over it. Attachments include spine protectors and rib protectors. A player may have a preference for vinyl straps and metal buckles or elastic straps as closures. Adult shoulder pads typically start at $90.00 and may reach $350.00 or more. Researchers at the University of Florida's College of Medicine have developed a way to air condition shoulder pads that is designed to regulate players' body temperatures during games and practice

When, in the judgment of the Referee, the level of crowd noise prevents the offense from hearing its signals, he can institute a series of procedures which can result in a loss of team time outs or a five-yard penalty against the defensive team.

1st and 10 sysytem technology

The first down line usually comes in orange and yellow. But most people take it for granted. It takes at least up to four people and a truck load full of equipment to provide this simple line that is drawn out on the field. The first down line originated from a company based out of New York called sports vision. Sports vision debuted its first and ten system during a game between the Bengals and the ravens. This game was broadcast on ESPN on September 27, 1998. Since that first game, sports vision has continued to provide ESPN, ABC and Fox sports with the ability to enhance their football telecast with this technology. So much more goes into the first down system than most people would realize. The orientation of the field with respect to the camera is very important so that they can paint the first down line with the correct perspective from that cameras point of view. The framework is very important because they need to know exactly where the yard lines on the field are. The system has to be able to sense the cameras movement such as tilt, pan, zoom, and focus to understand the perspective change that results from that movement. The system also has to be able to recalculate the perspective at a rate of thirty frames per second as the camera moves. A football field is not flat we all know that. A-line calculated by the system has to appropriately follow the curb of the field. A football game is filmed by multiple cameras at different places in the stadium, so the system has to do all this work for several cameras. The system has to be able to sense when players, referees or the ball crosses the first down line so it does not paint the line right on top of them. The system also has to be aware of superimpose graphics that the network might overlay on the screen so that they don't interfere with each other. All of these factors have to be taken into consideration. There are definitely some other key pieces such as special camera mount that holds the television cameras. This mount encodes all of the cameras Movement. Also the data mount produces and helps the computers understand what each camera is doing in real time. Finally a very big portion of all of this comes from a 3-D model of the field that helps everything tie itself into each other because it is an exact replica of the field. So the next time you see that 1st down line dont take it for granted.

Helmets

My idea for my video is to go around the locker room and ask teammates on the football team questions about their helmet and face mask. I am really going to focus on the face masks for the particular positions. I am going to ask them what they like about their face mask and how it is good for their position. Also I'm going to ask what they like about it personally. My project is definitely going to focus on helmet safety and the evolution of the helmet and football equipment.

History/Equiptment Overview

I am doing my blog on NFL football. Not only am I doing it on NFL football but I
am going to go over the basic rules and the equipment as well. I'm going To go
into depth about some of the rules and some of the individual equipment. I
think that the rules over time have changed for the good of the game. I also
believe the implementation of new equipment has made the game safer as well. I
will have a video segment on the helmet. I'm going to go over each individual
players by position and their helmet. I'm going to interview different Players
at each position and talk with them about their helmet and why they like or
dislike their face masks. Each position has different face mask for different
reasons and I am going into detail about why are why not they have a certain
face mask.These explorations should be very interesting because they are coming 
from football players point of view.
