Age and Gender Differences in the Physical Activity Patterns of Urban Schoolchildren in Korea and China
Physical activity in childhood is important as it may establish adult behavior. However, few studies on physical activity in children have been conducted, especially in Asian children. We performed anthropometric measurements of 159 school children in two grades (grade 5: 10-11 years old and grade 8: 13-14 years old) from urban areas of Korea (n=79) and China (n=80). The total daily energy expenditure (TEE) was estimated for 7 consecutive days us…
Thermal Insulation and Body Temperature Wearing a Thermal Swimsuit during Water Immersion
This study evaluated the effects of a thermal swimsuit on body temperatures, thermoregulatory responses and thermal insulation during 60 min water immersion at rest. Ten healthy male subjects wearing either thermal swimsuits or normal swimsuits were immersed in water (26 degrees C or 29 degrees C). Esophageal temperature, skin temperatures and oxygen consumption were measured during the experiments. Metabolic heat production was calculated from o…
Maximum Local Muscle Energy Metabolic Rate in Athletes
Three distance runners and three oarsmen were subjected to the prediction of maximum local energy metabolic rates of main seven muscle groups. Total energy metabolic rates and integrated bipolar surface electromyograms of the seven muscle groups were simultaneously measured during fifteen static resting and exercising items. The measurements of electromyograms were also performed during maximum voluntary contraction. Oarsmen had higher mean maxim…
Prediction of Maximum Local Muscle Energy Metabolic Rate in Voluntary Sustained Contraction
In order to determine the maximum local energy metabolic rates of seven muscle groups during maximum voluntary contraction (MVC), an application of our prediction method of local muscle energy metabolic rate (YOKOYAMA, 1980a) was considered. Total energy metabolic rates and integrated bipolar surface electromyograms of the seven muscle groups were simultaneously measured during sixteen static contraction conditions. The measurements of the electr…
Local Muscle Energy Metabolic Rate in Human Static Postures
According to the prediction method of local muscle energy metabolic rate by the author (1980a), local metabolic rates of five muscle groups were determined during eleven static postures. For the above purpose total metabolic rate and integrated surface electromyograms were measured and the simultaneous equations were solved on an electronic computer for each individual subject. The subjects were four young Japanese normal males. The predicted fiv…
A Prediction Method of Local Muscle Metabolic Rate
Though the total energy metabolic rate during exercise was three times of that duringrest, the sum of energy metabolic rates of internal organs during exercise was as same as that during rest (see Table 1; LEHMANN, 1953).JANSKÝ (1964) pointed out that when the maximal metabolic rate occured in human body assame as many other mammals the total energy metabolic rate ncreased to about ten times of basal metaboric rate (BMR). It was achieved mainly b…
A Study on Adaptation to Cold Environment
Seven Japanese male adults aged 23-28 were subjected to a cold environmental stress. Three of them were born and grew in Hokkaido district which is a northerland in Japan (HK group), and the other four were born, grew up in Honshu or Kyushu district in Japan and immigrated into Hokkaido (Non-H K group).Measurements of heart rate (HR) and bipolar surface EMG of 11 muscles were performed before and during exposure to the cold environment which was …
Effect of Muscular Activities on Energy Metabolism and Heart Rate in Different Static Postures
Simultaneous measurments of energy metabolism, heart rate and bipolar surface EMG's of 17 muscles during 11 static postures were performed with ten male adults aged 20-25. Because of stabilization of EMG in all subject muscles and minimum of coefficient of variation both for energy metabolism and heart rate, the integrated EMG in half rising posture with knee bending at 90° was presumed to unit of muscle activity for each muscle. When six transfo…
