It occurs about 100 times a game title in the Nfl: a bone-jarring tackle that slams a person to the lawn. On the play shown in the photo above, Seattle Seahawks defensive back again Marcus Trufant (23) drilled Philadelphia Silver eagles receiver Greg Lewis (83) with these kinds of force that Lewis could hardly hang on for the ball. (Seattle won the Dec. a few, 2005, game at Philadelphia 42-0 in the most lopsided shutout ever broadcast upon Monday Night time Football. ) Incompletions and fumbles aren't the only effects of such tackles. Much more than 100 pourriture are noted each period in the NATIONAL FOOTBALL LEAGUE. Given the size and speed of present athletes, it can surprising more gridiron players aren't carried off the discipline on their glasses. For that, they will thank high-tech gear that protects these people from the physics at play in the sport's fearsome collisions.
HALF A BUNCH OF HURT
At a few ft. 14 in. and 199 pounds, Marcus Trufant is a great average-size NFL defensive again (DB). Those stats avoid stand out within a league where more than 500 players weighed 300-plus pounds at the 06\ training camps. But a DB's mass combined with his speed -- on average, some. 56 just a few seconds for the 40-yard dashboard -- will produce up to 1600 pounds of tackling power, according to Timothy Gay and lesbian, a physics professor on the University of Nebraska and author with the Physics of Football.
HITTING THE DECK
Researchers charge a field's shock absorbency with a metric called G-Max. To evaluate it, an object that approximates a human neck and head (about twenty sq . in. and 20 pounds) is dropped by a elevation of 2 ft. A low G-Max means the field absorbs more strength than the gamer. Trufant and Lewis landed on lawn in Philly's new arena, which has a cushy G-Max of just over 60. Synthetic areas have G-Max ratings up to 120. The toughest turf: freezing grass.
LUGGING THE G-LOAD
Most of the people associate excessive g-forces with fighter aviators or astronauts. But common earthbound incidents can also improve g's. Few things complements the g-load of...
