Humans respond to painful exercise by "not moving at all (excessive avoidance behavior)", "moving while avoiding pain (pain suppression behavior)", "continuing to move without avoiding pain (pain behavior)", etc. Can take action.
While avoidance behavior for pain has short-term benefits of protecting the body from injury, if it continues after the wound has healed, it can be a factor in prolonging the pain.Yuki Nishi and Shu Morioka, Ph.D. students at Kio University Graduate School, conducted research to clarify the details of each behavioral characteristic for painful exercise and what kind of personality causes each behavior. rice field.
In the experiment in this study, we created and used the original task "Exercise gives pain and you can choose the action for pain by your own will".A pain stimulus is given while the subject fills the touch panel, and there is a mechanism that the pain stimulus is weakened when the subject fills the touch panel at a specific speed in a specific direction of movement.As a result, "people who take excessive avoidance behavior" who are overly afraid of pain and stop painting behavior, "people who take pain suppression behavior" who do painting behavior while avoiding pain, and "people who continue painting behavior without fear of pain" It can be divided into "people who take painful behavior".
As a result of the experiment, it is said that those who take excessive avoidance behavior take a long time to start exercising, that is, "hesitation of exercising" was observed.In addition, in those who take pain-suppressing behavior and those who take pain behavior, the fear reaction disappears at the same time as the pain stimulus disappears, whereas in those who take excessive avoidance behavior, even if the pain stimulus is stopped, they hesitate to exercise. The horror reaction remained.In addition, these individuals were found to have a high degree of damage avoidance temperament and trait anxiety, suggesting that the cautious type of personality, which tends to cause anxiety, may be a factor in the tendency to take excessive avoidance behavior.
This result can be said to show the importance of considering individual characteristics when evaluating human pain and the importance of evaluating avoidance behavior in detail.
