We assessed the caregiver's burden in the family and examined the factors which increase the care burden. For the assessment of the care burden we used the Japanese Version of the Zarit Caregiver Burden Interview (J-ZBI) and compared it with the caregiver's age, relationship, care term and the number of usage items of care insurance service. Analyzing the total score of J-ZBI and subscales in J-ZBI, correlations between the total score and subscales, and between subscales were found (p<0.05). The factors which increase the care burden could be extracted from the subscales. Being incapable of leading a former life greatly influenced the increase of care burden.

[Purpose] The aim of this study was to develop a conversion equation for the work load of the sit-tostand exercise (STSE) to the work rate of a cycle ergometer. [Subjects and Method] The conversion equation was derived using thirty-one healthy young male subjects, and verified with twelve healthy young male subjects. Both exercise methods were graded protocols. The items measuring work load were oxygen uptake and heart rate. The conversion equation was derived using multiple regression analysis. The object variable was the cycle ergometer work rate needed to generate the same oxygen uptake at each standing frequency. The explanatory variable were height, body weight etc. The conversion equation was verified at the same work rates for both exercise methods.[Results] The conversion equation was dependent on standing frequency, height, and body weight. The same work rates were used in both exercise methods, therefore oxygen uptake correlated with both methods.[Conclusion] The conversion equation can be used for young males.
