Human walking
歩行研究は日常生活における自然歩行と実験室内で実施される実験歩行に分けることができる。これらの方法から得られた結果は同じ速度であっても一致しないものがあり,またそれぞれの実験条件でしか観察できない内容もある。そこで,本稿では両者の結果を示すことにより,その違いを明確にしながらヒトの歩行の特徴を論じた。歩行の特徴は歩幅および歩調を資料として速度,性,年齢および民族別に考察した。またこれに加えて,自然歩行では時代,履物および地域差についても論じた。実験歩行については床歩行とトレッドミル歩行に分け,歩行時の上肢動作およびエネルギー代謝量についても言及した
Wijesekera, N. D., 1964
Six male students performing a standardized exercise were studied in the following conditions: (1) 15°C/50 % R. H. (cool condition), (2) 20°C/50 % R. H. (comfortable condition), (3) 35°C/30 % R. H. (warm-dry condition), and (4) 35°C/80%R. H. (warm-humid condition). The exercise consisted of pedaling a bicycle ergometer for 20 minutes at moderate work load followed by a 4-minutes period of heavy work. Pulmonary ventilation, oxygen uptake, carbon d…
Prediction Equations of Body Density in Japanese Young Men
This study was attempted to make new equations for predicting body density of Japanese young men from skinfold and/or girth measurements. The subjects were 31 healthy young men aged from 19 to 25 years old. Body density and some anthropometric parameters, such as body weight, height, skinfold thickness and girth, were determined. The body density was estimated by underwater weighing method. Subjects were immersed underwater in the squat position …
A Comparison of Maximal Oxygen Intake of Japanese Female Athletes Determined by Direct and Indirect Methods
Changes of the surface and needle electromyogram (EMG) of the biceps brachii in fatigue were investigated.The subjects kept a 10 kg weight applied to the wrist with the elbow flexed about 90°, until they were not able to maintain the elbow in this position. This exhausting contraction was repeated twelve times with a pause of 30 sec between each contraction until eight times. The pause durations from 9 th contraction to 12 th were longer than 30 …
The Change in Physical Working Capacity Shown as PWC 120 , PWC 150 and PWC 170 during Prolonged Muscular Exercise
The purpose of this investigation is to study the relations between the physical working capacity and rectal temperature during muscular exercise.Subjects were six healthy male young adults (Table 1). 60 minutes bicycle exercises were carried out at work rates requiring 30, 40, 50 and 60% of the subjects' maximal oxygen uptake. Heart rate and rectal temperature were measured every ten minutes during the works. Rectal temperatures ranged between 3…
The Effects of Prolonged Muscular Work on Oxygen Intake, Heart Rate and the Relation between Both of Them
Under a normal temperature environment we studied the effects of prolonged muscular work on heart rate and oxygen intake and the relation between both of them.The subjects were six healthy young male students (Table 1). They carried out one-hour work with a bicycle ergometer of 30, 40, 50 and 60% of their maximal oxygen intakes. This led to mean rectal temperature increases respectively 0.4, 0.6, 0.9 and 1.4°C. Submaximal work at first 30% and th…
Craniometrical Study of the Tohoku Japanese Skulls
Craniometrical data of the Japanese have been collected by many authors, regionally and chronologically. But we lack the data of the Toxoxu Japanese up to the present.The late Prof. M. YAMASAKI have had a project to study the Toxoxu Japanese skulls and collected the skulls in Toxoxu University. It is a great regret that neither study nor publication were completed. Prof. R. URA, Prof. T. MORI and Prof. M. KoHAMA discussed on the importances of th…
