A super-aging society will be realized in 2020, when one in four persons will be a senior citizen. Exercise is associated with a decrease in morbidity and mortality rates, and, in this study, the results of biochemical blood tests and physical features were compared before and after intervention involving health classes, with a focus on changes in pain-related complaints. There was a total of 43 participants (17 men [ages: 67.0± 6.7] and 26 women [age: 62.9± 7.3]), in whom the results of biochemical blood tests, physical features, the number of steps taken as measured by a pedometer, and pain-related complaints written in the comment field of the training diary were compared before and after the classes. There was a significant improvement in the body weight, waist circumference, systolic blood pressure, total cholesterol, and neutral fat after the intervention. The number of steps taken was significantly greater after the intervention, and the frequency of pain showed a tendency to increase during the intervention and decrease there after. It was estimated that intervention involving health classes is associated with an increase in the physical activity level, improvement in values of biochemical blood tests, and pain relief.
