Description

  The present invention relates to an exercise device used when a user exercises a body.

  In recent years, many people exercise their bodies using exercise devices for various purposes. Here, “exercise” refers not only to strength training but also to exercise in general, including stretching (flexible gymnastics to stretch muscles and joints), exercise to promote blood / lymph fluid flow and calorie consumption, and the like.

  As a conventional exercise apparatus, there is an apparatus disclosed in Patent Document 1, for example. In this apparatus, a weight, an elastic body (spring, rubber), etc. are mentioned as a load means. The effect and nature of exercise differ depending on the type of loading means.

  For example, in general, when considering stretching and exercise for maintaining and improving the health of the general public rather than strength training by professional athletes, in terms of preventing excessive load and individual differences in body, It is preferable to use an elastic body rather than a weight. The reason is that, in the case of the weight, the magnitude of the load is the same throughout the exercise, but in the case of the elastic body, the magnitude of the elongation of the elastic body is proportional to the magnitude of the load.

  Further, the spring 81 has a spiral spring body 811 that expands and contracts, and grooves that are screwed into both ends of the spring body 811, and two end portions (end portion 812, end portion 813) that do not change in shape, With the structure having, the possibility of breakage (rupture, deformation, etc.) due to metal fatigue can be reduced as compared with the conventional spring. In addition, the conventional spring is configured by, for example, deforming both ends of a spring body that expands and contracts in a spiral shape into a hook shape, and the hook-shaped portion may be damaged (ruptured, deformed, etc.) by metal fatigue. There were many.

  Further, by adopting a structure in which the spring 81 and the plate 71 can be used in combination, a flexible load setting can be made by taking advantage of the advantages of the spring 81 and the plate 71.

  And, with such an exercise device 1, it is possible to realize an exercise in which stretch and strength training are fused and developed. In other words, for the exercise apparatus 1, the spring 81 and the plate 71 can be used together, and the number of the springs 81 used as a load can be easily changed, so that athletes who perform strength training, health maintenance, constitution improvement, The exercise device 1 can be realized that is suitable for any of a wide range of people, such as general people who prevent physical strength and athletic ability from being lowered, or disabled persons and elderly people who perform physical function recovery and health management. Further, the use of the spring 81 that is unlikely to be damaged by metal fatigue at the end portion can reduce the maintenance effort and cost of the exercise apparatus 1.

  In addition, the effects on the user U who performed such exercise with the exercise apparatus 1 include increased metabolism, prevention of aging, fat removal, acquisition of muscle viscoelasticity, promotion of neuromuscular coordination, joints, Expansion of range of motion, improvement of peripheral circulation by stable physiological response, early recovery from musculoskeletal diseases such as ligament damage and fractures, recovery after cerebrovascular disorder, prevention and improvement of lifestyle-related diseases, tension of the exchange nervous system It can be expected to improve sleep disorders by relaxation, to train inner muscles, to prevent or reduce stiff shoulders and back pain.

Although description of this embodiment is finished above, the aspect of the present invention is not limited to these.
