2026-06-22 Comparative Study on Human Stepping Friction Between Different Age and Gender Groups doi:10.57760/sciencedb.39894 en To investigate the effects of age and gender on gait characteristics and tribological mechanisms during human walking, a study was conducted on the walking gait of individuals of various ages and genders on horizontal roadways. A total of 207 volunteers, including 103 males and 104 females, were recruited and divided into three age groups: 41-50 years, 51-60 years, and 61-70 years. Static plantar parameters, velocity, acceleration, contact forces were measured using plantar pressure plates, three-dimensional force platforms, and three-dimensional motion capture systems. Additionally, the required coefficient of friction (RCOF) was calculated. The results indicated that as age increased, male participants exhibited decreased asymmetry in foot lift height, total step length, step length asymmetry, and asymmetry in lateral heel load, while static load asymmetry between the left and right feet increased. The peak values of walking speed and acceleration gradually decreased. Females had higher Fx and Fy values than males, while males had higher Fz values than females in the 60-70 age group. With increasing age, the RCOF gradually decreased. In the 41-60 age range, males had higher peak RCOF values than females, with an earlier occurrence of RCOF1 and a later occurrence of RCOF2 compared to females. However, in the 61-70 age range, males had lower peak RCOF values than females, with both RCOF1 and RCOF2 occurring later than in females. The study found that gait stability gradually decreased in older adults, and there were differences in gait tendencies between males and females as they aged. Furthermore, the ways and mechanisms by which male and female elderly individuals regulate gait stability also differed. stepping friction; age; gender; gait parameters; required coefficient of friction Yang Xiaoxuan Pang Xianjuan Yue Yun He Tiantian Liu Zeyuan Zhang Yongzhen PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset Science Data Bank
