In 1989, the NCAA banned the kicking tee, requiring kicks from the ground. During the 2011 NFL season, a record 90 field goals of 50 yards or longer were made. During the 2012 NFL season, this record was increased to 92 field goals of 50 yards or longer.
Caloric Burn. Both body weight and level of intensity impact just how much caloric burn you will experience. Harvard Heart Letter notes that an individual riding the stationary bike at a moderate level for 30 minutes will burn an average of 210 calories at 125 pounds, 260 calories at 155 pounds and 311 calories at 185 pounds.
Obviously it'll be different for everyone, but my own stats from back in January say that I burned around 34 calories a mile cycling, whereas I burn around 100 calories a mile on foot. However, my bike rides would have me doing 2 miles in 15 minutes, whilst I covered 1 mile in 20 mins when walking. So, I could walk for an hour and burn 300 calories, or I could cycle for an hour and burn 272 calories. Not all that much different, at that level.
