Are There Health Benefits to Being A Vegetarian? The perception of the effects of a vegetarian diet on health has gone through a transformation in the last 20 years. In 1980 the American Dietetic Association (ADA) had serious doubts about whether a vegetarian diet was nutritionally sound [1].
Step 1. ENTER THE TRACK SIZE (i.e., the distance covered when completing one lap - normally in Lane 1) and select the unit of measure. most outdoor tracks are either 400 meters or 440 yards (4 laps to a mile) most indoor tracks are either 200 meters or 220 yards (8 laps to a mile) See NOTE 3 for determining track size. Also note that a very small number of tracks use a lane other than Lane 1 to define the track size (see NOTE 4).
High school, college and NFL football fields are the same size. A standard football field is 120 yards long. The playing field is 100 yards (300 feet) long, and each end zone is 10 yards (30 feet) deep. The field has a uniform width of 53 1/3 yards (160 feet). If you calculate the entire area of a football field, including the end zones, it works out to 57,600 square feet (360 x 160). One acre equals 43,560 square feet, so a football field is about 1.32 acres in size. The field is marked with a yard line every 5 yards, and every 10 yards is marked by a field number.
