The purpose of this study was to examine the effect of the walking in water which removed the buoyant force (buoyant force removal walking: B.F.R.W.) on respiratory and circulatory systems. Ten healthy college students wore a load weight equivalent to their own buoyant force and were ordered to walk in water of the water level of patella. In case of walking of 2.16 km per hour, oxygen uptake during walking in water or B.F.R.W. was significantly (p<0.01) greater than that during land walking. No significant changes in O2 pulse, heart rate and the double product were observed among walking in water, B.F.R.W. and land walking. These results suggest that B.F.R.W. can induce various degrees of exercise intensity in the closing movement chain reaction by changing walking speed and water level, and is applicable to muscle strengthening exercise for lower limbs and to physical endurance strengthening exercise.
