The present study was designed to investigate the kinematic factors related to sprint running velocity. The subjects were 71 sprinters(49 males and 22 females)who ranged from world class to collegiate level. Movements were recorded around the 60-m point from the start line during a 100-m race(during official races including world championships in athletics, or under experimental conditions)using 16-mm movie or video cameras. The official best time during recording of the movements was 9.86. The correlation coefficients between kinematic data(see Fig.1)and sprint running velocity were calculated for three groups(male, female, and all sprinters). Step length and step length index(step length/body height to exclude the effects of body height)were correlated positively and significantly with sprint running velocity for all groups(male, female, and all sprinter). Step frequency and step frequency index[step frequency・(body height/gravitational acceleration)^<1/2>to exclude the effects of body height]were correlated positively and significantly with sprint running velocity for all groups except male sprinters with regard to step frequency. With regard to leg swing, maximal thigh angle and maximal leg angle showed no significant correlation with sprint running velocity, but the minimal knee angle showed a singificant negative correlation with sprint running velocity for both male and all sprinters. These results suggest that the purpose of high knee drills generally carried out during training needs to be reconsidered. The maximal leg touch down velocity showed a significant positive correlation with sprint running velocity for both female and all sprinters. This probably means that the leg touch down velocity acts to reduce the deceleration at the moment of foot contact and to accelerate the subsequent leg swing back velocity during the foot contact phase. As for the support leg, the maximal leg swing velocity showed a significant positive correlation with sprint running velocity for all groups. Although the maximal hip extension velocity during the foot contact phase was correlated positively and significantly with sprint running velocity for male sprinters, the maximal knee and ankle extension velocity showed a significant negative correlation with sprint running velocity for female and all sprinters. These results suggest that the knee should not be extended to transfer the hip extension velocity effectively to the leg swing velocity during the foot contact period. This was borne out by the fact that the top sprinters entered in the present study hardly extended the knee of the driving leg during the foot contact phase.

[Abstract] The present study was aimed to develope a new ramp exercise protocol on a treadmill to determine aerobic endurance parameters for elite distance runners. Maximal exercise tests were performed on a treadmill by 15 healthy male collegiate distance runners (mean±SD, 19.9±1.0 years) using this ramp protocol. The linear increase of measured VO_2 was obtained during maximal exercise test. Aerobic endurance parameters (VT, RCP, VO_2max, RE and vVO_2max) were able to be determined in a single test. As a result, this ramp exercise protocol was effective to assess aerobic endurance parameters for elite distance runners.

目的:本研究は大学生男女個々および交互,相互におけるBMIと体型不満の関連について検討することを目的とした.方法:対象は全国14大学に在籍する18-22歳の男性学生4,118名,女性学生2,677名であり,体組成測定およびボディーイメージに関する質問紙調査を用いた横断研究を行った.体組成は健康診断の結果もしくは実測した.結果:対象の平均(SD)BMIは男性21.7(3.3)kg/m2,女性は20.9(2.7)kg/m2であった.BMIが18.5未満の者の割合は男性11.1%,女性14.6%であり,BMIが18.5-24.9の範囲の者の割合は男性76.1%,女性78.9%であった.BMIに対する理想不満度(理想のシルエット-現在のシルエット)と健康不満度(健康的なシルエット-現在のシルエット)の間に男性は交互作用が認められなかったけれども,女性では有意な差が認められた(p<0.001).魅力的な男性のシルエット値は,男女間に有意な差はみられなかった(t=1.231,p=0.218,d=0.04).一方,男性からみた魅力的な女性のシルエット値は平均4.65,女性が思う男性からみた魅力的な女性のシルエット値は平均3.97であり,女性は男性に比べ有意に低い値を示した(t=25.08,p<0.001,d=0.70).結論:女性大学生の考える健康的な体型は理想体型より太い体型であった.魅力的な男性のシルエットは男女間に差がみられなかった.しかしながら,魅力的な女性のシルエットは男性より女性においてより細い体型と考えていることが示唆された.

【Abstract】 The aims of the present study were to investigate characteristics of variations in substrate metabolism with time during prolonged exercise in trained women and to examine the optimal exercise intensity and duration of endurance training in women as exercise prescription. Expired gas was measured in ten trained women who performed 120-min treadmill walking and running at several exercise intensities. Substrate oxidation was computed by substituting determined oxygen uptake and carbon-dioxide output into stoichiometric equations. A constant level of energy expenditure was needed during prolonged exercise at the same intensity, but the enhancement of lipid metabolism with exercise duration led to an increase in fat-derived energy provision and a decrease in the dependency ratio of carbohydrate-derived energy to required energy. Lipid metabolism during low-intensity exercise wasconstantly-enhanced with duration whereas that during moderate- and high-intensity exercise was slowly increased beyond 60 min after initiating exercise and the proportion of fat-derived energy to required energy decreased with increasing exercise intensity. These findings suggest that women inendurance training should continue low-intensity exercise for as long time as possible and that they should select the moderate-intensity to sustain exercise beyond 60 min in order to increase the total volume of energy expenditure.
