The effects of upper strength-training on muscular and peripheral-circulation systems of lower limbs in spinal cord injuries.

本研究旨在探讨高位力量训练对脊髓损伤(SCI)患者肢体肌肉和周围循环系统的影响。SCI组在8周内每周自愿进行3次上肢力量训练。本研究的主要发现概括如下：1.在常规训练的SCI中，臂部和腿部的静息血流与正常人(AB)相同。2.上力量训练对SCI大臂和小腿的血管扩张能力大于AB。4.在8周的力量训练期间，SCI的血压逐渐升高，但在4周停止力量训练后，血压恢复到原来的水平。本研究表明，上力量训练对SCI大鼠的肢体肌肉和周围循环系统无训练作用。而血压在8周训练期间逐渐升高。因此，建议在力量训练期对脊髓损伤患者进行必要的血压监测。

The purpose of the present study was designed to investigate the effects of upper strength-training on muscular and peripheral-circulation systems of lower limbs in spinal cord injured persons (SCI). SCI had volunteered strength training of upper limbs three times a week in 8 weeks period. The major findings in this study were summarized as follows ;1.In regularly trained SCI, resting blood flow of arm and leg showed the same as abled body persons (AB).2.It was obtained vasodilatation capacity in SCI have grater of arm and lower of leg than AB.3.Upper strength training was demonstrated no training effects on muscular and peripheral-circulation systems of lower limbs in SCI.4.Blood pressure of SCI was gradually elevated during 8 weeks strength-training period, however it was returned previous level by 4 weeks detraining who had discontinued strength training at 4 weeks.This study was showed to no training effects of upper strength training on muscular and peripheral-circulation systems of lower limbs in SCI. However, blood presser was gradually elevated during 8 weeks training period. Therefore, it was recommended to necessary monitoring blood presser in SCI during strength training period.
