PDF Exercise Prescription for Aged Men and Women in Water

【Supercategory:7. DESCENTE SPORTS SCIENCE Subcategory:7.15 Vol.15

 Treadmill (flowmill) walking in water is a potentially useful therapeutic modality. Since energy costs of this activity were unknown, we evaluated oxygen intake (Vo₂), heart rate and blood lactate of flowmill walking in water at speeds of 20 to 50 meters/min (m/min) in 10 m/min increments in 15 old aged subjects.
 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 1.6 to 3.9 and 8.1 to 33.4 mg/dl, respectively.
 Flowmill walking in water could increase the enengy expenditure of movement depending on the speed, and the response to increasing was exponential.

  x : walking speed (m/min)
  y : energy expenditure (×⁻¹⁰⁰kcal/kg/min)
