New mode of exercise (flowmill) in water is a potentially useful therapeutic modality. Science energy cost of this activity were unknown, we evaluated oxygen intake, heart rate, and blood lactate of flowmill walking in water. Twenty male subjects were paticipated in this study; their age, stature, body weight, and %fat were 48.5±4.7 years old, 167.1±4.8cm, 59.8±7.3kg, 16.7±3.4%, respectively. Velocity of walking and water were 30, 40, 50, and 60m/min. Walking were performed 15 minutes. The relationship between heart rate and oxygen intake was linear, and relationship between walking speed and oxygen intake was exponential in flowmill walking. Mets and blood lactate to flowmill walking were 2.2 to 6.2 and 7.7 to 33.4 mg/dl, respectively. Flowmill walking in water could increase the energy expenditure of movement depending on the speed, and the response to increasing speed was exponential. y = 1.34 · e(0.03x), r=0.9997, (p<0.001), x: walking speed (m/min), y: energy expenditure (x100 Kcal/kg · min).
