Estimation of vertical displacement during ascending evacuation

摘要：

　　This paper describes an ascending evacuation model based on physical work capacity, when exhaustion may play a key role during evacuation.The experiment was carried out on a stair machine (Stair Master, SM5,USA) which involved 13 male and 12 female subjects.Individual climbing speeds at 50% and 70% of their maximal aerobic capacity (% VO2max) level (L1 and L2) were selected for 3 minutes, and 90 %, the last level (L3)was up to 5 minutes or until exhaustion for the model development on the first 19 subjects.The model was then validated on the last 6 subjects with intended exercise levels at their 60%, 75% and 90 % of their maximal aerobic capacity corresponding up to 120, 15 and 5 minutes of continuous work, respectively.The maximum vertical displacement (hvert, in m/min) can be calculated according to: hvert =-21.7727 + 0.4024 * VO2max + 0.2658 * % VO2max.
