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.
Defining Grip Strength. Grip strength is usually defined using a right-handed playerâs left hand or a left-handed playerâs right hand. A neutral grip centers the thumb on top of the clubâs grip; the V formed by the thumb and forefinger point toward the playerâs chin. In a weak grip, the hand is rotated so that the thumb is turned toward the target. In a strong grip, the hand is rotated so that the thumb is turned away from the target.
