Five healthy male swimmers, aged 10 to 12, swam tethered using the breast stroke at 32 degrees C, 25 degrees C and 20 degrees C water temperature in a flume, and biked at 25 degrees C air temperature in contrast with swimming. In swimming, the resistance started at 1.0 kg and increased in 1.0 kg increments up to the point of exhaustion, and in bicycling, started at 0.5 kp with 60 rpm and increased in 0.5 kp increments, respectively. The subjects swam or biked for 5 min during each period, with a rest of 10 to 20 min until they had returned to their resting HR level. The last exercise intensity was for 5 min with the maximal weight the subjects could support. The last min of VO2 and 30 sec of HR were measured during each exercise period. The subjects gave their RPE assessment at the end of each exercise. The relationships between %VO2max and HR were linear with a high correlation coefficient (r = 0.995-0.998) in both water and air. However, the slope of the %VO2max-HR line tended to shift to the right in colder water. Increased VO2 of swimming in cold water was largely attributed to shivering. The RPE increased exponentially against %VO2max in both water and air and deviated more from linearity against HR. The RPE in 25 degrees C water was lowest at all submaximal swimming. At maximal swimming, however, the RPE in the four conditions were much the same. It seemed that the RPE responded differently from HR in varying water temperatures.","PeriodicalId":77409,"journal":{"name":"The Annals of physiological anthropology = Seiri Jinruigaku Kenkyukai kaishi","volume":"13 1","pages":"23-31"},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2114/ahs1983.13.23","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19121244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The characteristics were: the amount of subcutaneous fat, body weight, height and surface area, maximal aerobic capacity and maximal voluntary isometric contraction of the trunk flexors. Ten male subjects wearing shorts and jogging shoes were exposed to 27 degrees C and 10 degrees C for 60 min. The cooling resulted in a decrease of 6.8 +/- 0.3 degrees C (mean +/- SE) in mean skin temperature. The temperatures of m. triceps and m. deltoideus were decreased by 2.8 +/- 1.0 degree C and 5.1 +/- 0.4 degree C, respectively. Rectal temperature was virtually unaffected. A significant negative correlation (r = -0.785) was found between the amount of subcutaneous fat and decrease in mean skin temperature after cooling. After the exposures to 27 degrees C and 10 degrees C, the subjects performed an overhead ball throwing test to measure muscular performance. The test was performed in a standing position using both arms. Five balls weighing from 0.27 kg to 3.0kg were thrown. On the average, cooling decreased muscular performance 7.6%. The decrease correlated significantly only with the amount of subcutaneous fat r = -0.710). The results indicate that from the measured physical characteristics, varying within normal range, only subcutaneous fat had significant effect on thermal responses. Accordingly, the decrease in muscular performance correlated only with the amount of subcutaneous fat.","PeriodicalId":77409,"journal":{"name":"The Annals of physiological anthropology = Seiri Jinruigaku Kenkyukai kaishi","volume":"12 6","pages":"335-9"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2114/ahs1983.12.335","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19115229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To unify the level of activity in skeletal muscle of the lower limbs, some rats were treated by surgical sciatic denervation. After the experimental period, rats were anesthetized and their plantaris and soleus muscles were removed. Muscle samples were homogenized and analyzed for the mitochondrial enzymes malate dehydrogenase (MDH) and 3-hydroxyacyl-CoA dehydrogenase (HAD) activities by spectrophotometer. Sciatic denervation caused a decrease in MDH and HAD activities in both the plantaris and the soleus. Hypoxia also reduced MDH activity in the denervated plantaris muscle. As the ATP demands in the plantaris of hypoxic rats might be equal to that of normoxic rats, the reduction of MDH levels by hypoxia was not caused by a decreased level of muscle activity during hypoxic exposure. Our results indicate that chronic hypoxia has a negative effect on the oxidative enzyme MDH activity in rat skeletal muscle.","PeriodicalId":77409,"journal":{"name":"The Annals of physiological anthropology = Seiri Jinruigaku Kenkyukai kaishi","volume":"12 6","pages":"363-9"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2114/ahs1983.12.363","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19115232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The subjects were five young male adults. The manual handling task was standardized and the repetition frequency was in self-pace. The arm movements were characterized by the different direction measured from the frontal plane of the subject between 0 degrees to 150 degrees combined with the distance measured from the acromion to the fixed points of 300, 500 and 700mm. The movements to all of the fourteen points tested were evaluated on both sides of the arms and shoulders by the integration of the EMG signals (IEMG) as to m. deltoid pars media and clavicularis, m. trapezius pars descendens, m. pectoralis major pars clavicularis and m. extensor carpi radialis brevis. It was found that IEMG of the deltoid muscles were sensitive to the direction and distance of the arm movements while the trapezius muscle showed the relative lower dependence on the direction. There were significant combined effects of the direction and distance in all muscles; i.e. effect of reach distance was greater with decreasing the arm angle, which was obvious at distance longer than 500mm in the arm abduction. When IEMG was divided by the task time in self-pace which increased in the arm abduction, the peak value was observed at the angle of 30 degrees. It was suggested that if the repetitive movement was required at the same frequency as at the angle of 30 degrees the position near the arm abduction (the angle of 0 degrees) would become the most expensive working direction.","PeriodicalId":77409,"journal":{"name":"The Annals of physiological anthropology = Seiri Jinruigaku Kenkyukai kaishi","volume":"12 6","pages":"341-50"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2114/ahs1983.12.341","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19115230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some of them are produced by constraints such as surface, shoes or opponent. In kick action of walking, the ground reaction force (GRF) is the most important external force. The magnitude of the GRF, its direction, and point of application have an influence on the load on the human body. The purpose of this study is to clarify the role of forefoot joint (artt. metatarsophalangeae) at the force exerted upon the floor during kick action of walking. The device used in this study to analyze the GRF and its three components consists of Kistler's force platform. Output from force transducer was collected online with a TEAC data recorder and MEM-4101 minicomputer. The impact force measurements were taken from the anterior-posterior force time curves at the take-off for 1 subject walking 10 trials at 2 m/sec with 2 different pairs of shoes (Shoes 1: thin sole of 4mm, and Shoes 2: thick sole of 40mm) and without shoes. High speed (200f/sec) cinematography was also used to analyze the angular displacement of forefoot joint at the take-off of walking exercise. The force acting at the forefoot joint may produce the anterior-posterior force of the GRF which is defined as the propelling power acting on the human body during walking exercise. The result showed that the impact force peak occurred 40-60 msec before take-off and the propelling part of kick action accounted for only about 6% of the external force.(ABSTRACT TRUNCATED AT 250 WORDS)","PeriodicalId":77409,"journal":{"name":"The Annals of physiological anthropology = Seiri Jinruigaku Kenkyukai kaishi","volume":"12 6","pages":"371-8"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2114/ahs1983.12.371","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19115233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
