The purpose of this study was to investigate the physiological and psychological effects of sit to stand exercise using a video game. Twelve young male adults performed sit to stand exercise with a video game and without a video game. Heart rate, oxygen consumption (VO₂), electromyogram of lower limbs (%MVC) and perceived exertion (RPE) were measured during exercise. Mood states (POMS) were measured before and after exercise. There were no significant differences in physiological measurements between the two conditions. On the other hand, depression scale was significantly decreased after exercise only in the game condition. These results suggest that sit to stand exercise with a video game may have positive psychological effects without change in physiological load compared to the same exercise without a video game.

A case of chylorrhea arising after median sternotomy for treatment of atrial septal defect was reported. The patient was a 55-year-old male, who had visited our outpatient clinic with a complaint of edema in the bilateral lower legs in June 1990. Under a diagnosis of atrial septal defect, a patch closure was performed in November. On the 5th postoperative day, a full liquid diet was started. Two hours and a half after the food intake, the drainage from a tube inserted into the anterior mediastinum turned milky white. Chylorrhea was diagnosed. The patient was placed in N.P.O. and maintained by an intravenous hyperalimentation. Drainage of 250-350ml/day milky white fluid persisted until the 14th postoperative day, when a 5cm removal of the mediastinal tube resulted in dramatic decrease in drainage. Thus chylorrhea in this case was cured by conservative treatment.
