“…After that the ascent speed remains a constant of around 0.52 m/s. Lam et al [14] studied the ascent velocity of student with the age of around 10-20 years old in Hong Kong and found that the ascent speed decreases with the participants ascending to a higher level. The highest velocity on the first three levels by Lam et al l [14] is in the range of 0.5 m/s to 0.55 m/s, which is slower than our observation.…”

The highest velocity on the first three levels by Lam et al l [14] is in the range of 0.5 m/s to 0.55 m/s, which is slower than our observation. Choi et al [15] studied the individual ascent speeds of student with an average age of 23.4 years old in Korean and they found that the fastest ascent speed is 1.5 m/s on the first two levels, and the average ascent speed over the first five floors is 1.1 m/s for the males and 0.8 m/s for the females.…”

“…Serious concerns in evacuation research include the physiological limitations, maximum capacities and durations in climbing stairs. Nonstop prolonged ascending can be required in an emergency evacuation to reach a safe refuge level from deep underground structures, such as subways and in high-rise buildings (Lam et al 2014;Ronchi et al 2015;Delin et al 2016). From both the performance and evacuation perspectives, it is impossible for a person to continue ascending with the same maximum speed for a long duration.…”

“…Several field and laboratory studies have assessed ascending capacity by measuring heart rate (HR) and blood pressure and oxygen uptake (VO 2 ) and have estimated energy costs in preferred and prescribed speeds on different stair machines (O'Connell et al 1986;Butts, Dodge, and McAlpine 1993;Bassett et al 1997;Teh and Aziz 2002;Lam et al 2014). On a step mill, the relative VO 2 values observed were 26, 32, 38 and 46 mLÁmin À1 Ákg À1 during ascending for 5 min at 60, 77, 95 and 112 stepsÁmin À1 , respectively (Butts, Dodge, and McAlpine 1993).…”
