Cardiorespiratory response during sandy beach walking
Lack of exercise is one of the main factor of life style disease. It is known that aerobic exercise is effective for preserve and promote of health. In the recent years, aerobic exercises is performed by many people for awareness to health. Walking was selected as exercise for health in many cases, to walking technique is easy to practice even for beginners. Improved exercise intensity of walking was reported various researcher, but there was no verification of walking effect of sandy beach. The purpose of this study was investigate to cardiorespiratory response during sandy beach walking. Healthy eleven men and women participated in this study after informed consent. There physical characteristic were follows; age, 23.1 ± 5.7years, height, 169.9 ± 9.3 cm; body weight, 63.6 ± 7.5 kg. Participants were walked sandy beach and asphalt road for 15 minutes. Average walking speed were adjusted 3 and 4 km per hours by speed mater. Heart rate response was measured every 5seconds. In addition, oxygen uptake and heart rate response during treadmill walking were measured at 10 second intervals, and to determine the relationship between oxygen uptake and heart rate. Oxygen uptake of sandy beach and asphalt road walking were estimated by the relationship of oxygen uptake and heart rate. Statistical processing was used one way repeated measures of analysis of valiance. Statistical significance was accepted at p < 0.05. The result of this study, Heart rate response and oxygen uptake of sandy beach walking were significant higher than asphalt road in both speed. Consequently, it was clear that sandy beach walking was benefit as health exercise than asphalt road walking.
