| Outline of Final Research Achievements |
There is large Individual variations in physical activity. This may be associated with differences in the environmental, genetic and trait, and fatigue and infectious factors. Our studies indicated that 1) high-intensity physical activity was associated with a plurality of SNPs in chromosome 4 and 8, 2) mitochondrial DNA polymorphism was associated with the strength and agility, 3) shopping and living environments were associated with walking and physical activity, and 4) the interaction of intestinal immunity and intestinal flora were associated to changes in physical activity. These findings suggest that the variability of physical activity may be affected by some internal and external factors, moreover immunity and infection.
