Outline of Final Research Achievements

When it performed a control condition and cooling condition after exercise, a big difference was seen in T1 value in MRI.It is speculated that the change of T1 value might be feasible to represent a temperature change and proved that it is said the T1 value is one of factors related deeply to temperature.
This method is expected to be useful to evaluate the effectiveness of rehabilitation or training in sports where cooling is very common and in heavy usage. However, the T1 value is not able to demonstrate the absolute temperature, therefore to obtain real temperature, further study to know relationship between T1 value and real temperature using a needle temperature sensor will be needed.
