Objective:The purpose of this study is to confirm the exercise effect when combining wearable exercise assist robot, Bot fit's resist mode (Samsung Electronics) and stair climbing. Design: Cross-section study Methods: Targeting 53 adults and seniors, foot pressure and muscle activity were measured when climbing 3-story stairs using foot pressure measurement equipment (W-insole Science System) and surface muscle activity measurement equipment (sEMG; FreeEMG, BTS Bioengineering, Italy) using Bot Fit's resist mode. All subjects were measured without wearing Bot Fit, and the data between the two conditions were compared and analyzed. Results: The front area(p 0.01) and middle area( < p 0.05) foot pressures of adults significantly increased when wearing the Bot < fit. Frontal area foot pressure significantly increased in elderly people with knee arthritis and obesity(p 0.05). The gastrocnemius < activity in all subjects significantly decreased after wearing Bot Fit(p 0.01). In elderly people with knee arthritis, the muscle < activity of the rectus femoris was significantly reduced(p 0.05)., and in obese elderly people, the muscle activity of the < gastrocnemius muscle was significantly reduced(p 0.05).< Conclusions: Based on the results of this study, it is possible to induce correct stair climbing posture when climbing stairs using Bot fit resistance mode. In particular, it is expected to be an effective exercise for strengthening muscle endurance by increasing the activity of the rectus femoris muscle.
