We investigated the effect of kurozu, a brewed vinegar, on the NK cell activity and peripheral blood cells in 18 university student cyclists. They were assigned to two groups, one of 11 drinking kurozu, and the other of 7 cyclists not drinking it. The drinking group was given 30 ml of kurozu a day for 80 days. Both groups performed an equal amount of training for 80 days. The NK cell activity was significantly decreased by 80 days of training in the non-drinking group (from 71.9 ± 15.9% to 61.9 ± 11.3%) (p < 0.05), but not in the drinking group. Kurozu therefore prevent the degradation of NK cell activity by intense training, suggesting its contribution to the physical condition of student bicycle racers.

There have so far been no studies examining the physical fitness and physical activity (PA), measured using objective measures, in homebound elderly people. The purpose of this study was to examine physical fitness levels and PA patterns and evaluate their relationships in homebound elderly people. In 2004, a total of 3964 community-dwelling elderly aged 65 years and over participated in a base line survey. The subject data were directly collected by in-home interviewer. Subjects were defined as being homebound if they went outdoors less than once a week. However, the subjects who could not go out without assistance due to sickness and/or disability were excluded from the analysis. In 2005, 38 homebound (22 men, 16 women) and 70 non-homebound (33 men, 37 women) older adults who participated in the base line survey were selected. Measurements of physical fitness levels and PA patterns measured using an accelerometer, were taken in 2005. The total steps per day did not significantly differ between homebound and non-homebound men and women. The time spent in 1.8 METs activity (corresponding to activity level 1 of the accelerometer) was significantly higher in women than in men for non-homebound and homebound, respectively. The time spent in lower-, moderate-, and high-intensity PA did not significantly differ between homebound and non-homebound men and women, respectively. Handgrip strength, knee extensor strength, leg extensor power, stepping and maximum walking speed were significantly higher in non-homebound than in homebound men and women. These results suggest that the physical fitness levels of homebound were lower than those of non-homebound, but no difference was observed in the PA levels between homebound and non-homebound.
