Method for measuring golf swing efficiency
First Claim
1. A method for comparing the dynamic characteristics of a golfer'"'"'s body with the dynamic characteristics of the golfer'"'"'s swing, comprising:
- determining force components of the golfer'"'"'s body by measuring forces transmitted through each of the golfer'"'"'s feet during the golfer'"'"'s swing;
determining a resultant force based on the force components;
determining the club head velocity of a golf club swung by the golfer; and
comparing the resultant force with the club head velocity.

Abstract
A method and apparatus for determining the efficiency of an athlete'"'"'s body movement is disclosed. With particular reference to the sport of golf, the present invention relates to measuring the ground reaction forces of a golfer during a golf swing. The ground reaction forces may be resolved into a single value. At the same time, the dynamic characteristics of the golf club are also measured, including the golf club head velocity. Comparing the single value to the club head velocity allows the golfer'"'"'s efficiency to be determined. The efficiency may be used for a wide variety of purposes, including fitting golf equipment, technique improvement, and fitness assessment.
