COMPARISON OF GOLF SWINGS

SWING I is that of an ordinary golfer.
SWING II is mine,

"a" gn each swing indicates path of backswing and
"Bl!" the topmost hand position in the backswing.

The following points are of interest:

(1) The are of the backswing in II is much
wider than in I. This is brought about by a more com-
plete extension of the left arm,

(2) This extension plus a more effective
wind-up of the hips brings the hands at 'B" noticeably
higher in II than in I. The position in II is one of
greater potential power.

(3) The loop in the path of the club head
as the swing changes direction is apparent in II and
absent in I. In II the plane of the downswing has
dropped away from the camera so that the club head
may be brought upon the ball from inside the Line of
flight. The radius of the downswing has been further
shortened by the retention of almost the full angle
of wristcock during the early stages.

(4) In the second half of the downswing, in
swing II the intervals between successive club posi-
tions are greater than in sewing I because the uncock-
ing of the wrists in this area contributes to contin-
ually increasing club head speed,

(5) In II the player has relaxed after mak-
ing the hitting effort and has allowed the momentum of
his swing to carry his club well around his neck at the
finish, Swing I, being much shorter after impact indi-
cates that this player is still feeling tension.
