 note = {Anthropometric items, handgrip strength and aerobic power were measured for 151 Mexican boys and 172 Mexican girls ages of 8 to 18 years living at Léon city (1850 m altitude), Guanajuato State, Mexico. Subjects volunteered from 4 different socio-economic classes such as High, Middle, and Low classes from city and Rural class from suburb. The items of anthropometric measurements were as follows: body height, weight, girth of 7 parts (head, chest, abdomen, upper arm, forearm, upper leg, and lower leg), length of 4 parts (upper extremity, lower extremity, lower leg, and chest depth), and skinfold thickness of 4 parts (arm, back, abdomen-front, and abdomen-side). Aerobic power was measured by means of maximum running on a motor driven treadmill. Expired gas was collected into Douglas bags minute by minute and analyzed by micro-Scholander technique. The mean values of body height for 8, 10, 12 and 14 years old boys were 120.6, 133.3, 140.8 and 154.2cm, respectively. The mean values of body weight of 8, 10, 12 and 14 years old boys were 22.2, 30.8, 33.1 and 44.1 kg, respectively. These values were smaller by 5-11 cm in body height and 5-12 kg in body weight in comparison with those of Japanese boys in the same age. The mean values of body height for 8, 10, 12 and 14 years old girls were 124.2, 133,5, 147.5 and 153.6 cm, respectively. The mean values of body weight of 8, 10. 12 and 14 years old girls were 24.5, 28.8, 40.2 and 45.6 kg, respectively. These values were smaller by 4-13 cm in body height and 3-9 kg in body weight in comparison with those of Japanese girls in the same age. The mean values of skinfold thickness (arm + back + abdomen-front) for boys were greater in the order of High class (15.2-22.3 mm), Middle class (19.2-34.4 mm), Low class (18.7-25.4 mm) and Rural class (15.3-18.5 mm) at the ages of 9 to 12 years. The mean values of skinfold thickness (arm + back + abdomen-front) for girls were greater in the order of High class (36.8-53.8 mm), Middle class (33.9-51.8 mm), Low class (25.9-38.1 mm) and Rural class (17.6-34.5 mm) at the ages of 9 to 12 years. The mean values of aerobic power (ml/kg·min) for 8, 10, 12 and 14 years old boys were 53.4, 51.6, 52.1 and 55.6 ml/kg·min, respectively. The values were greater in the order of High, Middle and Low classes. Aerobic power of Mexican boys ages of 8 to 14 years was greater by 3-17% in comparison with that of Japanese boys (measured by authors) in the same age. The mean values of aerobic power (ml/kg·min) for 8, 10, 12 and 14 years old girls were 46.2, 47.5, 41.9 and 41.9 ml/kg·min, respectively. Girls of Rural class showed highest values of 53.4 and 55.0 ml/kg·min at the ages of 9 and 10 years, respectively, among the girls of 4 different classes at the same age. Aerobic power of Mexican girls ages of 9 to 14 years was greater by 3-21% in comparison with that of Japanese girls in the same age.},
