The joint force calculation section generates a double pendulum model that includes a first link that corresponds to an upper part of a body of a golfer, a second link that corresponds to a golf club, and a joint that links the first link and the second link, and calculates a joint force applied to the joint along with a swing motion using an acceleration measured by an inertial sensor attached to the golf club. The torque extraction section extracts a torque that causes the second link to make a rotational motion around a first axis from the joint force."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Golf swing analysis device and golf swing analysis method","description":"A golf swing analysis device includes a joint force calculation section and a torque extraction section.
