BATTLE OF THE FREE RADICALS. Some antioxidants are produced by the body and some by plants, and so they can be derived from the diet. Their job is to combat free radicals â highly reactive molecules formed as a natural by-product of cellular activity.
Grip (tennis) In tennis, a grip is a way of holding the racquet in order to hit shots during a match. The three most commonly used conventional grips are: the Continental (or Chopper), the Eastern and the Western. Most players change grips during a match depending on what shot they are hitting.
It involves a handshake-type grip, where the object being gripped rests firmly against the palm and all fingers. A strong crush grip is useful in bone-crushing handshakes or for breaking objects with pressure. In a pinch grip, the fingers are on one side of an object, and the thumb is on the other.
