A sports glove includes an index finger portion, a middle finger portion, a ring finger portion, and a little finger portion, as well as a back portion and a first resistance portion. The back portion is connected to the index finger portion, the middle finger portion, the ring finger portion, and the little finger portion. The back portion covers a back of the wearer's hand. The first resistance portion has flexibility. The first resistance portion is disposed on at least one selected from the group consisting of the back portion, the ring finger portion, and the little finger portion such that when the index finger, the middle finger, the ring finger, and the little finger are bent, a magnitude of bending resistance applied to the little finger or the ring finger is greater than that applied to the middle finger or the index finger.

A calculating unit of a swing analyzer calculates, assuming that a golf club is in a uniform circular motion about a virtual center of rotation O during a swing, a virtual speed Vh at a central point R of a golf club head, based on a distance between first and second acceleration sensors, a distance between the first acceleration sensor and the central point R of a golf club head and outputs from the first and second acceleration sensors, and calculates the speed of central point R of a golf club head utilizing the virtual speed Vh.

Swing analyzer

A measuring device includes a strain gauge, a processing unit calculating an expected bending point value corresponding to a bending point position, and a display unit capable of displaying an output value from the processing unit. The processing unit calculates the expected bending point value based on a measured value of strain gauge at a first time point during a swing of the user and a measured value of strain gauge at a second time point closer to an impact time point than the first time point. The processing unit stores in advance conversion data for converting the expected bending point value to recommended kick point output value indicating kick point, and the processing unit outputs the recommended kick point output value corresponding to the calculated expected bending point value to the display unit.

A glove of the present invention includes a stretchable member and protective members arranged on a side corresponding to a back of a hand, and when the glove is placed in a stationary state and viewed from the back side, the stretchable member forms two or more separate curve surfaces, and upper end portions thereof are located somewhere in lower half parts of finger covering parts, each of the curve surfaces formed with the stretchable member extends toward a wrist part, crossing a center line of at least one finger covering part selected from a second finger (forefinger) covering part, a third finger (middle finger) covering part, a fourth finger (ring finger) covering part, and a fifth finger (little finger) covering part, at least twice in a region from the upper end portions to a normal to the center line of the third finger (middle finger) covering part that passes an interdigit part between the first finger (thumb) covering part and the second finger (forefinger) covering part, and in regions between the curve surfaces of the stretchable member, the protective members are provided. This configuration makes it possible to provide a glove that is capable of following changes in shape caused by a gripping action of the hand, providing both of the feeling of fitting and the feeling of support, and having a high-level protection function and a high-level mobility function.

Glove

In a glove having finger covering parts, a finger covering part corresponding to at least one finger selected from the third finger (middle finger), the fourth finger (ring finger), and the fifth finger (little finger) is configured by arranging protective members (to) on anterior and posterior sides of the same, and arranging stretchable members (to) on both lateral sides of the same. An inner perimeter of each finger covering part is substantially equal to an outer perimeter of the finger corresponding thereto. The stretchable members on the lateral sides of each finger have stretching forces such that a stretching force of the stretchable member on the lateral side on the first finger (thumb) side is higher than a stretching force of the stretchable member on the other lateral side on the fifth finger (little finger) side. When the glove is bent from an opened state to a gripping state, the finger covering part is bent with a twist at a gripping angle toward the first finger (thumb) side. Thus, a glove is provided that is capable of following changes in shape caused by a gripping action of a hand, providing both of the feeling of fitting and the feeling of support, and having a high-level protection function and a high-level of mobility function.

A golf club head ( ) has an ellipsoid of inertia ( ) with its center at a center of gravity G. When the ellipsoid of inertia ( ) is virtually cut with a plane passing through the center of gravity of the golf club head ( ) and being parallel to a face surface ( ), a major axis of a plane ellipse ( ) appearing on its cut surface forms an angle of &thgr; with an intersecting line ( ) of the cut surface and a ground surface ( ). The major axis extends upward and away from the ground surface ( ) as it approaches a toe part ( ). The angle &thgr; is not smaller than 0.5&deg; and not larger than 9.5&deg;. An aspect ratio a/b defined by a ratio of the length a of the major axis ( ) to the length b of a minor axis ( ) of the plane ellipse ( ) is not smaller than 1 and not larger than 4.
