In an ergonomic study involving a group of 41 male students from the University of Hong Kong, each student was asked to exert maximum upward force on a horizontal bar which was close to floor level, with his feet 400mm away from the bar. The force, averaged over a 5-second period, is called the 'maximum voluntary isometric strength' (MVIS) and is recorded in kilograms.
