概要	The purpose of this study was to examine how water movements and carrying distances affect physical exertion, tiredness, and trunk movements of elderly females carrying 3-liters of water in water bags with different capacities on their backs. The participants were 15 early elderly females (median age 71, range 67-74). The cardio vascular responses and the trunk movements of four different carrying conditions were measured for the distance of 500 meters in an indoor hallway. Three of the four conditions were carrying 3 liters of water in bags with different capacities (3-liter, 6-liter, and 10-liter), and the fourth condition was carrying nothing. The average carrying speed for all conditions turned out to be 1.4 meters/second and the ratings of perceived exertion on the Borg scale was 11 (fairly light). However, the relative heart rates varied from 77.1 to 80.3 (%HRmax), which we considered to be a little intense. For the 10-liter water bag, the trunk movements from the starting point to the 35-meter point was significantly less than the other water bags (p<0.05). What affected the physical exertion and the tiredness was the carrying distance. It was clear that the differences in capacity of water bags affect the trunk balances right after people start walking.
