Introduction: Walking is the active movement of the body with alternating motions of the lower limbs, usually resulting in transferring the body from one place to another. Walking on stairs represents a physically more demanding activity compared to walking on a flat surface. Specifically, during this activity, the muscle system of the lower extremities must exert additional force to overcome the variable heights and depths of each step. Objectives: The aim of this research was to examine the initial contact (with fingers or full foot) during stair ascent both without and with a load, and to identify the most commonly used types of initial foot contact with the step in the participants' sample. Subjects and methods: The study involved 30 participants aged between 19 and 23 years. Data was collected by recording using a mobile phone and then imported into the biomechanical software Kinovea. The obtained results were analyzed using Excel. Data analysis included descriptive statistics and a chi-square test for dependent samples at a significance level of p<0.05. Results: During stair ascent without resistance, a greater number of participants had initial contact with their toes, while during stair ascent with resistance, an equal number of participants had initial contact with their toes and the full foot. The results indicated that the types of initial contacts with the step during stair ascent in younger individuals were approximately the same, both with and without a load. Additionally, during stair ascent with a load, additional resistance did not have any impact on athletes but only affected non-athletes. Conclusion: Resistance certainly affects the position of the foot during the initial contact with the step, but to some extent.
