Traveler's thrombosis has posed a severe problem around the world. Much research has been conducted to find effective approaches to traveler's thrombosis. We examined a proto-type ankle exerciser equipped on a plane seat in order to assess its effectiveness. The purpose of the first study is to determine a suitable exercise tempo. Three tempos of 30, 60, and 90 times per minute were examined with young male and female subjects by measuring heart rate and blood pressure during five-minute exercise. Heart rates at 90 times per minute were higher than those of other tempos. Blood pressure did not show any differences among the three tempos. We determined 60 times to be the suitable tempo because of the mildness and smoothness of the exercise. The second study is on changes of calf circumference during two-hour sitting and five-minute exercise. Calf circumference after two-hour sitting showed an increase of 1.4% in young male subjects, and 2.2% in young female subjects. The five-minute exercise made for a 0.5% decrease in men and a 1.3% decrease in women. There was a 0.9% improvement by each the exercise. Middle-aged men and women, however, did not show any improvement after exercise. The third study was on skin temperature and blood flow in the foot during two-hour sitting and five-minute exercise. Three of all six subjects showed a clear decrease in foot temperature during sitting and an increase during exercise. The results of two subjects, however, were contrary to the above-mentioned results. The temperature of another subject fluctuated up and down during sitting, and then steeply increased during exercise. Blood flow during exercise increased three to ten times in comparison with sitting. These results lead to the conclusion that the proto-type ankle exerciser connected to a plane seat might serve to prevent traveler's thrombosis.
