A study was carried out to confirm the present states of physical training and nutritional condition in sportsmen on the growing stage. Energy expenditure (EE), caloric intake (CI), food items, body weight, running distance for 12 min and hematological and biochemical parameters of blood and urine were measured in 17 high school boys during intense summer baseball training for seven days. EE was estimated from the records by direct observation of activities during the baseball training (RMR method), and CI was calculated from the dietary record supplied each subject for the seven observation day.
Following results were obtained.
1) The average EE was 55.4±7.5 kcal/kg/day, and the CI corresponded to 87.2% of the EE, although no significant reduction of body weight was observed at the termination of the training session.
2) Running distance for 12 min gradually decreased.
3) Significant decreases in serum TG, TP and Hgb concentrations, and a remarkable increase in CPK activity were observed on the 4 th and final days. Urinary excretion of phosphate, urea nitrogen and catecholamines also increased gradually.
4) The greater the increase in negative energy balance (CI-EE), the greater the decrease in TG, TP and Hgb concentrations, and the greater the increase in serum CPK and urinary excretion of catecholamines.
The present results suggest that greater intake of total energy, protein and fat is recommended for development of endurance capacity, baseball techniques and sound growth in occasion such as the present baseball training program in high school boys.

A 56- year-old woman visited our hospital complaining of right hypochondralgia. X-ray and endoscopic examinations revealed Borrmann 2 type gastric cancer in the anterior wall of an upper part of the stomach. Ultrasonography showed an echogenic mass in the suprarenal area. The mass which had septal formation within it, was about the same in density as fat on computerized tomography, and was hypovascular fed by the right inferior adrenal artery on angiography. These findings suggested that the mass might be adrenal myelolipoma. After total gastrectomy and right adrenectomy were done, histopathological study confirmed that the case is adrenal myelolipoma associated with Borrmann 2 type gastric cancer. In Japanese literature, only 54 cases of surgically resected adrenal myelolipoma have been reported, and this is the second case of adrenal myelolipoma associated with gastric cancer.
