Estimated Energy Expenditure

Estimation method of metabolic equivalents during short duration walking and running considering EPOC

Amount of daily physical activity is strongly associated with the prevalence of lifestyle-associated diseases, and thus maintaining a certain level of physical activity is recommended. Amount of physical activity, namely energy expenditure, is commonly estimated from linear regression analysis of oxygen uptake during steady-state exercise of different intensities. Short-duration exercise, mainly walking lasting less than 3 minutes, has been reported to account for over 90% of the daily energy expenditure of healthy adults. The estimation of energy expenditure by ACSM Metabolic Equations used well, however, is based on steady-state exercise of more than 5 minutes, and energy consumption of shorter duration exercise is not commonly considered. Oxygen consumption remains elevated for some period of time after exercise. Then, the estimation of energy expenditure for short duration exercise must include excess post-exercise oxygen consumption (EPOC). The amount of EPOC change in duration exercise. Therefore we try an estimate of the energy expenditure in consideration of EPOC.

Study on Wearing Effect of Compression Garment in Daily Living

There are many reports of effects of compression wear, mainly in the case of high intensity exercise, such as reduction of heart rate and muscle pain. There are not many reports on this effect in daily life. Purpose of this research verify effects of compression wear on daily life activity state.

Study on Motion Sickness Sensor

At present, the spread of automatic driving vehicles is expected worldwide. Since automatic driving vehicles are controlled by a machine, it is thought that a problem of motion sickness of passengers becomes serious as human's sensory feedback operation does not enter. Therefore, research and develop a motion sickness sensor that detects motion sickness.

Evaluation Method of Walking Function of Cognitive Impairment Patient

We study the method of estimating the level of disability from the degree of variation of the waveform by measuring the walking state of elderly with cognitive impairment using the acceleration / angular velocity sensor attached to the waist.

Study on Estimation of Walking State Using Foot Pressure Sensor

In recent years, list type health care devices are commercially available from each company, but it is difficult to always wearble them. If it is a system built in shoe insole, you can wear it with just wearing shoes and you will not be conscious of sensor wearing. In this research, we will study the estimation method of walking state using foot pressure sensor information built in insole.

Research on Motorcycle Rescue Robot

In order to realize the EV motorcycle type rescue robot driven by the front and rear wheels, we study the driving method, the automatic driving control, the fall prevention mechanism.
