Correct stride length and less knee-lift can increase running efficiency

The most efficient runners have the longest stride length, the least vertical "bounce," and the least deceleration at footstrike. Coaches Peter Coe and David Martin offer this advice: Increase your stride length by improving the strength and flexibility of your legs and hips. A low knee-lift and practice can reduce up-and-down motion. Finally, you will decelerate the least at footstrike by making sure you don't overstride.

Too much calcium?
With so many foods enriched with calcium now on the market, you can unwittingly exceed the limit of 2,500 milligrams recommended by the National Academy of Sciences. Too much calcium on a daily basis can cause headaches, irritability, and kidney problems. While calcium is essential to maintain bone density, use regular exercise rather than excess supplementation to enhance its benefits.

Farm-raised fish may be healthier
Farm-raised freshwater fish contain lower levels of pesticides than fish caught in the wild, according to recent research published in the Journal of Food Science, because fish-farm ponds are cleaner than natural lakes. A good seafood store should be able to tell you where their fish came from, and most fish served in restaurants is farm-raised.
