The present invention relates to a haptic reaction exercise device, and more particularly, is worn on the user's wrist or ankle so that the user can perform resistance exercise by calculating the magnitude and orientation change of the user's force during exercise or in the direction opposite to gravity. By applying a load to a haptic technology-based weight-increasing response exercise device, it relates to a gravity-directed weight-increasing haptic response exercise device for strengthening muscle strength, in which a user can obtain the effect of actually lifting an exercise device by using the haptic technology-based weight-increasing response exercise device.

In 2017, the World Health Organization (WHO) classified sarcopenia as a disease. ) as a disease rather than a simple concept of senescence, it is necessary to actively prevent and treat it.

However, the specificity of changes in the musculoskeletal system due to sarcopenia is not considered, and general exercise aids such as thera band and beauty dumbbells are being used. Therefore, there is a risk of injury if the exercise aid slips out of the hand or misses the device due to a decrease in muscle strength during exercise. Therefore, it is necessary to develop an ergonomically designed exercise aid that can assist the elderly who have been diagnosed with sarcopenia, not the healthy elderly.
