Summary of Activity

Our goal is to provide evidence-based information to solve the current social problems; global warming and advanced aging. Human beings have lived broadly on the earth by their high ability to adapt the hot/ cold environments by nature. However, the amenity that they acquired, including food and medical conditions, has deteriorated their ability and the waste of natural resources to attain the amenity has accelerated the depletion of the resources to cause the global warming. To cut the viscous circle, we would like to propose to reactivate their genetic resources to adapt the environments.

Research Subject

  • ・ To provide the strategy to prevent heat illness during exercise
  • ・ To provide the strategy to prevent lifestyle-related diseases with deterioration of physical fitness with aging
  • ・ To provide the epigenetic mechanisms for the effects of exercise training

Outlook for Research

We have developed e-Health Promotion System, composed of Interval Walking Training (IWT), portable calorimeter, and IT network system. By using the system, we have accumulated the database (DB) on the effects of 5-mo IWT in several thousand middle-aged and older people. By using the DB, we will develop a program to predict the effects of IWT to encourage the participants to continue IWT from their physical characteristics with genetic background. Thereby, we will transform medical service from treatment to prevention.
