The prevalence of knee osteoarthritis in a group of 50 former top-level football players was studied. The impact of knee osteoarthritis on joint function and joint structure was also assessed in the group of <a href=”http://www.watchxfootballonline.com/”> football players </a> compared to a control group.
Study participants in the football player group were male, over 45 years old, with no previous history of knee trauma, arthritis, arthropathy or surgery.
Study participants in the control group were non-sporting males who were otherwise well-matched (in terms of age, weight, height, and dominant foot) to the football group.
The two groups were compared for frequency of knee osteoarthritis, severity of pain and disability, and severity of structural impairment. Initially, it was noted that 40 of the 50 former football players were overweight. Half of the football group had played in more than 200 games. Results of the study showed that knee osteoarthritis, determined by x-ray and clinical examination, was more common in the football players (80%) than nonsporting group (68%). The difference was not considered statistically significant though. Here’s what was most interesting:
Pain was noted in only 6 of the football players, but was observed in 50% of the nonsporting control group.
Disability was noted in 6 football players and 23 nonsporting participants. Not only was disability more frequent, disability was more intense in the nonsporting group.
Over 57% of football players showed high levels of damage on x-ray compared to 29% of the nonsporting control group.
Interestingly, researchers concluded that knee osteoarthritis is common in male football players, yet the condition is generally less painful and less disabling than for nonsportsmen — in spite of being more destructive.
Walter Camp was born April 17, 1859, in New Haven, Connecticut. He attended Yale from 1876 to 1882, where he studied medicine and business. Walter Camp was an author, athletic director, chairman of the board of the New Haven Clock Company, and director of the Peck Brothers Company. He was general athletic director and head advisory football coach at Yale University from 1888-1914, and chairman of the Yale football committee from 1888-1912. Camp played football at Yale and helped evolve the rules of the game away from Rugby and Soccer rules into the rules of American Football as we know them today.
One precursor to Walter Camp’s influence was William Ebb Ellis, a student at the Rugby School in England. In 1823, Ellis was the first person noted for picking up the ball during the soccer game and running with it, thereby breaking and changing the rules. In 1876, at the Massosoit convention, the the first attempts at writing down the rules of American football were made. Walter Camp edited every American Football rulebook until his death in 1925.
Walter Camp contibuted the following changes from Rugby and Soccer to American football:
one side retained undisputed possession of the ball, until that side gives up the ball as a result of its own violations
the line of scrimmage
11 on a team instead of 15
created the quarter-back and center positions
standardized the scoring system, numerical scoring
created the safety, interference, penalties, and the neutral zone
tackling as low as the knee was permitted – 1888
a touchdown increased in value to six points and field goals went down to three points – 1912
The NFL or the National Football League, was formed in 1920.
