PURPOSE : Stairwell walking is frequently used as a vehicle to move the human body along with flat walking, and because of its horizontal move ment and vertical climb, the strength of walking on a level surface is gr eater. Therefore, it is prepared to examine the activity of the lower mu scles and provide basic data for comparison with the level of ground wal king for more efficient operation when walking on stairs.
METHOD : In this study, 30 adults with no neurological or neurometric problems were surveyed, and the experimental stairs were used (height = 15 cm, width = 23 cm, angle = 30°). Also, the flat ground was mea sured by selecting three or four of the five meters for four walking.
RESULT : We selected 15 men and women and compared the muscle ac tivity of walking on stairs and level ground. The result is as follows. 1. As a whole, the number of Bicepsfemoris and Gastrocannemius incr eased statistically when Rectusfemoris and Tibialisanterior steps down fr om level ground. 2. There was no statistically significant difference between men and w omen. 3. There was no statistically significant difference between overweight and underweight based on BMI23.
CONCLUSIONS : Compared to flat-land walking and up stair walking, re sult of walkers who climbed the stairs increased overall, particularly in t he normal weight, with a statistically significant value. Compared to flat -land walking and down stair walking, For women, only Bicepsfemoris w as statistically significant; the rest was not significant. For men, only Ga strocannemius was statistically significant; the rest was not significant. For Overwight, only Tibialisanterior was statistically significant; the rest was not significant. For normal weight only Gastrocannemius was statisti cally significant; the rest was not significant.
