Physical fitness of children aged 5 and 6 years.

Maximal oxygen uptake (Vo2 max) of 85 healthy kindergarten children, 46 boys and 39 girls, aged 5 and 6 years, was determined by means of track running. Their physique, skinfold thickness, grip and back muscle strength, and performances of 25 m-run, 50 m-run, standing broad jump, and 5 min-endurance run were also measured. Skinfold thickness of girls was significantly larger than that of boys. Boys were significantly superior to girls in all the motor performances. The Vo2 max per unit of body weight was 49.46 ml/kg/min for boys and 46.30 ml/kg/min for girls, the sex difference being significant at the 0.001 level. The correlation coefficient between Vo2 max per kg body weight and 5 min-endurance run performance was 0.417 for boys and 0.049 for girls, while that between absolute Vo2 max and body weight was 0.899 for boys and 0.563 for girls. The regression equation of the absolute value of Vo2 max (liter/min) on body weight (kg) was: Y=0.051X-0.025 for boys and Y=0.024 + 0.408 for girls, the regression coefficient of boys being twice as large as that of girls. It appears that at ages 5-6 sex differences are exhibited ont only in muscle strength and agility but also in endurance run and aerobic work capacity.

[Radiation therapy and surgical management of pineal tumors--follow-up study of 96 patients (author's transl)].

This is a follow-up study of 96 patients with pineal tumors, except for one patient who was lost to follow-up. 60 of these tumors were verified histologically either at operation or at necropsy, 6 were diagnosed by epitheloid cells existing in the cerebrospinal fluid, and 30 were diagnosed by clinical and ventriculographic findings. In agreement with Russell and Rubinstein, we have classified the histologically verified tumors into 3 groups, as follows; 1. True Pinealoma Group (Pineocytoma, Pineoblastoma), 2. Germinoma-Teratoma Group, 3. Others (Glioma, Cyst). The following points need to be emphasized in the planning of management: 1. Pinealoma (Two cell pattern pinealoma) responds favorably to radiation therapy. 18 of 43 patients of pinealomas who were treated with irradiation are functioning normally in various life situations for more than 5 years. Among them, 5 cases of pinealomas treated with irradiation alone have more than 10 years survivals. 2. There is a limitation in the efficacy of irradiation therapy in cases of spinal cord implantation, infiltration in adjacent structures or subependymal infiltration along the ventricular cavity. 3. Only 2 of 67 patients with pinealomas had spinal cord metastasis. It seems undesirable to subject all patients to complete cerebrospinal axis irradiation. 4. Successful removal were performed in 4 patients with teratomas and are now alive for 9-21 years. None of them, however, are doing well clinically with many neurological deficits. 5. Since adenocarcinoma, teratocarcinoma, teratoblastoma and others are not sensitive to radiation therapy, only the palliative treatments are available. 6. Therefore, the most promising treatments for pineal tumors is that irradiation, plus shunting operation when required, is a first choice and after irradiation, radical removal should be tried in the case of teratoma diagnosed by clinical and ventriculographic findings.

Aerobic work capacity of mentally retarded boys and girls in junior high schools.

The maximal oxygen uptake (Vo2 max) and ergometer load at a heart rate of 170 beats/min (PWC170) were determined in mentally retarded children (74 boys and 53 girls) of ages 12-15, whose IQ ranged from 36 to 91, and the results were compared with those for normal children. Mentally retarded boys and girls showed significantly inferior body height and weight, but no significant difference was found in skinfold thickness. The mean value of PWC170 for boys and girls was 14.34 kpm/kg/min and 11.31 kpm/kg/min, respectively, significantly less than that of the normal group. The mentally retarded boys had mean VO2 max per unit body weight of 42.4 ml/kg/min, which was significantly less than the 51.2 ml/kg/min of normal boys. The mentally retarded girls had a mean of 33.1 ml/kg/min which was also less than the 41.3 ml/kg/min of normal girls. The correlation coefficient between body weight and PWC170 (kpm/min) was 0.711 and 0.720 for boys and girls, respectively, while that between body weight and VO2 max (liter/min) was 0.641 for boys and 0.656 for girls. No significant correlation was found between IQ and PWC170 (kpm/kg/min) nor between IQ and VO2 max (ml/kg/min) both for boys and for girls. Similarly, no significant correlation was found between mental age and the VO2 max value (ml/kg/min).
