Claim:
1. A method for analyzing a golf swing, comprising: measuring movement of a subject performing a golf swing using sensor elements; communicating the movement measurements to a computer-based analysis system; and using the computer-based analysis system to calculate values for at least three of the following parameters: upper torso rotation at impact, upper torso rotational velocity at impact, peak upper torso rotation, peak upper torso rotational velocity, pelvic rotation at impact, pelvic rotational velocity at impact, peak pelvic rotation, and peak pelvic rotational velocity, and at least three of the following additional parameters: clubhead speed at impact, clubhead height, peak free moment/mass, peak X-factor, X-factor at impact, peak S-factor, S-factor at impact, peak O-factor and O-factor at impact, wherein X-factor is the relative difference between the rotation of the hips and the shoulders, S-factor is the obliquity or tilt of the shoulders in relation to the horizontal, and O-factor is the pelvic obliquity or tilt of the hips in relation to the horizontal.
