✦ Synopsis

This study examined the influence of a generalized physical fitness training program\ on manual material handling (MMH) capability. Thirteen healthy women trained for 14 weeks, 'prforming progressive resistance training three days per week and running with interval training two days per week. Subjects attended 85316% of the sessions. Compared to values obtained before training, subjects increased the maximum mass they could lift from floor to knuckle height by 19% (68-81 kg, p qO.001) and from floor to chest height by 16% (49-57 kg, p ~0.001). They improved by 17% their ability to lift 15 kg as many times as possible in lOmin(167-195 lifts, p < O.OOl), while perception of effort (measured with the Borg Rating of Perceived Exertion) did not change. Total body mass did not change, but body fat mass was reduced by 9% (18.8-17.2 kg, p = 0.036) and fat-free mass increased by 6% (48.2-51.0 kg, p < 0.001). A short-term physical fitness program, conducted about 1 h per day, five days per week, can substantially improve women's MMH capability and provide favorable changes in body composition (increased fat-free mass and decreased body fat).
