本研究の目的は, 力発揮能力改善を目的としたトレーニングであるクイックリフト (以下QL) 動作時の力発揮特性とそのメカニズムを検討することである. 代表的なQLであるパワークリーンを対象に挙上重量が大きい者と小さい者各6名の動作分析の結果, 最大挙上重量が大きい者は, 下肢関節最大トルクとセグメント間のエネルギの流出入量が大きく, 特有の反動動作が見られた. さらに, 最大挙上重量が大きい者と小さい者各10名の筋電図分析と動作分析の結果, 挙上重量が大きい者と小さい者間の下肢関節伸展筋の筋活動度は同等で, 屈筋と伸筋の筋活動から推定した関節剛性と関節トルク立ち上がり速度は挙上重量が大きい者の方が反動動作の前後において大きな値を示した. このことから, QL時の大きな力発揮には下肢関節の剛性を巧みに制御し, エネルギ伝達の効率化を図る必要があることが示された.

The purpose of this study is to elucidate the energy metabolism in a simulation of the fifth section of the Hakone Ekiden(disrance of 20.7km)using a runner-motion-response-type treadmill in a laboratory. Five male runners aged 20.2±.6 years were asked to run at their desired speds on a programmable treadmill whose"slope-setting"was changed automatically every fifty meters. The runners watched a video of the acrual course during this experiment. We found a significant correlation between the slope every fifty meters and the mean step length(r=-0.695)and step frequency(r=0.646). The mean values of oxygen uptake and respiratory exchange ratio of the five runners were 59.83±5.42(range 56.35-62.55)ml/kg/min and 0.99±0.05(range 0.97-1.01), respectively. The total energy expenditure and energy expenditure deduced from carbohydrates and lipids in this fifth section were 1632±58 kcal, 1502±120 kcal, and 130±96 kcal, respectively. In the case of an upward slope, we observed a significant correlation between energy expenditure(kcal/kg)for the five runners and mean step length(r=-0.942), mean step frequency(r=0.918), and running time(r=0.982). These results indicate that about 90% of the total energy used in the fifth section is supplied by the carbohydrate component and showed the high intersity of exercise during this section. In conclusion, our results for the upward slope showed that good long-distance runners use a longer step length, and thereby save energy and thus realize an improved running economy.

Previous studies have reported that the alpha-actinin-3 (ACTN3) and angiotensin-converting enzyme (ACE) gene polymorphisms are associated with sports performance, muscle strength, muscle power, and endurance. Competitive judo requires high levels of muscle power, muscle strength, and endurance. However, thus far, associations between these gene polymorphisms and muscle power in judo athletes have not been reported. The purpose of this study was to investigate the relationship between ACTN3 and/or ACE gene polymorphisms and middle power in judo athletes. This study recruited 79 male judo athletes from a top-level university in Japan. Genomic DNA was extracted from the saliva sample taken from each athlete. Genotyping using either polymerase chain reaction (PCR)-restriction fragment length polymorphism or PCR was performed to detect ACTN3 (rs1815739) and ACE (rs1799752) gene polymorphisms. Each athlete also performed a 30-s Wingate anaerobic test with a resistance equal to 4.5% of the athlete’s body weight.One-way analysis of variance revealed a significant difference in middle power relative to weight among the ACTN3 genotype groups (p<0.05). In other words, RX individuals showed significantly higher middle power than XX individuals (p<0.05). Moreover, middle power relative to weight was higher in individuals with the RR+RX genotype than in those with the XX genotype (p<0.05). However, there were no significant differences in the ACE genotype.The results of the present study suggest that ACTN3 but not ACE gene polymorphisms may be associated with middle power in judo athletes.

本研究では、柔道選手の競技能力及び形態・体力と遺伝子多型の関連性を明らかにすることを目的とした。男子大学柔道選手216名の alpha Actinin 3(ACTN3)、アンジオテンシン変換酵素(ACE)、インスリン様成長因子(IGF-2)など10個の遺伝子多型について解析した。さらに対象者は形態および体力測定を半年に1回実施し、最高競技成績に基づいて競技力を決定した。その結果、ACTN3及びACE遺伝子多型と柔道の競技力の関連性は認められなかったが、IGF2遺伝子多型は競技力との関連性が認められた。またACTN3及びIGF2遺伝子多型は一部の筋力関連項目との関連性が認められた。

<p> 本研究はバスケットボール選手の試合中における高強度運動について、心拍数を指標に定量化することを目的とした。大学男子バスケットボール選手(延べ27名)を対象に、選手の胸部に心拍センサーを装着し、試合開始から試合終了までの心拍数を計測した。最大心拍数の測定には漸増負荷測定時の最大値を採用した。試合に10分間以上出場した選手のデータを用いて、出場時間に対する最大心拍数の90%以上を記録した時間の割合について検討した。その結果、最大心拍数の90%以上を記録した時間の割合は49.1 ± 26.0%であり、その時間は540.5 ± 341.0秒であることがわかった。ポジション別に比較すると、ビッグマンはペリメーターに比べて最大心拍数の90%以上を記録した時間の割合が低いことがわかった。出場時間の約半分が高強度であるこの割合を、試合を想定した練習・トレーニングでも考慮するべき可能性がある。</p>

The purpose of the present study was to determine the effects of a resistance training program in triathletes. Eight healthy university competitive men's triatheletes who had no experience of the resistance training were assigned to either the resistance training group(TRAINING : N=4)or the regular training group(CONTROL : N=4). The resistance training program that Johnston et al.(1995)used for women long-distance runners was carried out three times a week, for ten weeks in TRAINING. Body weight, body fat, muscle cross-sectional area of thigh, squat 1RM, leg press power, isokinetic strength, and the incremental exercise using treadmill were examined before and after the training. At the same time, VO_2max and blood lactate concentration were also measured. The main results were as follows; 1) In regard to body weight, body fat, and muscle cross-sectional area of the thigh, no significant changes were found in either the TRAINING a CONTROL groups. 2) In the case of squat 1RM and leg press power, a significant increase was noted in the TRAINING group (p<0.01,p<0.05). There were no significant changes in isokinetic strength for either the TRAINING or CONTROL group. 3) There was no significant changes in VO_2max/BW in either groups. However, there was a significant increase in blood lactate concentration in the TRAINING group (p<0.05). 4) There was a positive correlation between the percentage change in leg press power/squat 1RM and in blood lactate concentration (p<0.05)in both groups. From these results we suggest that the resistance training program in triathletes was useful to improve the muscle strength and power without muscle hypertrophy, and to enhance during endurance high intensity exercise.

The purpose of this study is to obtain some basic data on the judogi chin-up training method for improving women judoists KUMITE strength and the testing method for determining its effectiveness. The subjects in this study are women collegiate judoists, concerning whom the number of chin-ups from a suspended judogi was measured. Also examined was the relationship between those results and the practitioners body shape, weight class and other physical strength measurement results along with the technical characteristics of their judo skills. The findings are as follows : 1) The average measurement value of their judogi chin-ups was 5.0 ±3.0 times which was 31 % of men's reported in the past. 2) There was a significant negative correlation between the measurements of their judogi chin-ups and their weight, but there was no significant correlation between the measurements of their judogi chin-ups and their body fat percentage. 3) Regarding the average measurement value of judogi chin-ups by rankings, the average for light weight class was significantly higher than that for middle weight class, and the average for middle weight class was significantly higher than that for heavy weight class. 4) There was a significant positive correlation between the measurements of their judogi chin-ups and their number of chin- ups from a regular bar. But there was a significant negative correlation between the measurement's of their judogi chin-ups and their strength of grip. 5) There was a significant negative correlation between the measurement of their judogi chin-ups and their 1RM of power clean, but there was a significant positive correlation between the measurement of their judogi chin-ups and their 1RM weight ratio for bench press. 6) The measurements of the group of right-hand KUMITE chin-ups tended to show greater values than those of left-hand KUMITE chin-ups. It implied that there was a positive correlation between features of KUMITE and judogi chin-ups. 7) There was no significant correlation between the measurements of their judogi chin-ups and their rankings and records in judo.
