项目摘要

本研究の目的は、比較的軽負荷強度で行う筋発揮張力維持法(Low-intensity resistance exercise with slow movementand tonic force generation:LST)を用いたレジスタンストレーニングの動脈・血管系に与える影響について調べることであった。以下の横断研究と運動介入から以上の検証を行った。横断研究結果30歳-50歳の男性中年者層の、(1)主にLSTに近い形態でのレジスタンストレーニングを十年以上続けている競技ボディビルダー(BB群)、(2)主に高負荷を用いたレジスタンストレーニングを十年以上続けている競技パワーリフター(PL群)、(3)定期的な運動習慣のない対象群(CON群)の3グループにおける動脈硬化度等の測定を行った。動脈硬化度を示す動脈スティッフネスはBB群、PL群においてCON群よりも有意に高かった。運動介入研究結果定期的な運動習慣・喫煙習慣のない男子大学生を用いて、(1)LST法を用いた全身のレジスタンストレーニングプログラムを行う群(LST群)、(2)高負荷を用いた通常の全身のレジスタンストレーニングプログラムを行う群(HN群)、(3)運動を行わない対象群(CON群)の3群を用いて週2回・3ケ月間の運動介入を行った。LST群においてHN群と同等の有意な筋肥大と筋力増強効果を認めた。動脈硬化度の指標である脈波伝播速度(PWV)はLST群においてのみ有意な低下(硬化度の改善)が認められた。CON群においてはいずれの測定指標においても実験期間前後に有意な変化は見られなかった。以上より、運動介入実験から、LSTでは通常の高負荷を用いたHNと同等の筋肥大・筋力増強を達成しながら、動脈硬化度に望ましくない影響を与えないことが確認された。横断研究において、LST的なトレーニングを主に行うBB群において動脈硬化度が高かったことは、BB群がLST的なトレーニング以外のトレーニングにもこ高負荷重量を用いたトレーニングも行っているためと考えられる。

In this study, the purpose of this study is to compare the strength of the tendons and the strength of the tendons (Low-intensity resistance exercise with slow movementand tonic force generation:LST). The purpose of this study is to use the method of force maintenance (Low-intensity resistance exercise with slow movementand tonic force generation:LST) for the purpose of this study. The following cross-sectional research activities are involved in the above-mentioned activities. The results of the cross-sectional study were 30-50 years old, male middle-aged adults, (1) LST patients who had been in the middle-aged group for more than ten years (BB group), (2) high-aged workers who had been in the market for more than ten years (PL group), (3) regular monitoring of the number of elephants (CON), such as the degree of hardening, and so on. The degree of dynamic hardening indicates that there is an intention to increase the temperature of BB group, PL group, CON group and so on. The results of the exercise intervention study showed that regular exercise training was conducted in male college students, (1) the LST method was used to treat male college students, (1) the whole body exercise was used to treat male college students, (1) the LST method was used to treat male college students, (1) the exercise intervention study was conducted, and (2) the exercise intervention study results showed that regular exercise training was conducted in male college students, (1) the whole body exercise was performed in the whole body (HN group), (2) the exercise intervention study was conducted. (3) the movement of the elephant group (CON group) and the third group of the elephant group will be involved in the bank operation during the three-month period. The LST group is similar to the HN group in terms of their intention to increase their strength and strength. The degree of dynamic hardening refers to the speed of broadcast (PWV), the speed of broadcast, the speed of LST, the intentional decrease (improvement of hardening), the propagation speed of wave, and the speed of propagation. The CON group indicates that there is an intentional change before and after the warning period. The above exercise, exercise intervention, and LST are usually used to make sure that the same amount of steel is enlarged and strengthened with the same amount of HN, and the degree of hardening is expected to have an effect on the temperature and the strength of the steel. The cross-sectional study was conducted on the basis of the data of the cross-sectional study, that of the LST group, that of the BB group, that of the BB group, and that of the LST group of the BB group, in addition to that of the LST group, and that of the LST group.
