This study investigated the effects of 1 year of regular wheelchair rugby training on the pulmonary function of subjects with tetraplegia. A total of 15 male subjects with tetraplegia participated in this study and were divided into an experimental group of rugby players (n = 8) and a control group (n = 7) of sedentary tetraplegic subjects. Both groups underwent spirometry, and the experimental group was tested before and after participating of a regular 1-year program of wheelchair rugby training. At the beginning of the training program, all the subjects presented reduced pulmonary function compared with predicted values (p < 0.05) for healthy subjects. There were a significant increase in forced vital capacity (FVC), forced expired volume after 1 second (FEV1), and maximal voluntary ventilation (MVV, p < 0.05) values after 1 year of regular wheelchair rugby training. The regression analysis between total training time and spirometric variables FVC (r = 0.97, p < 0.0001) and MVV (r = 0.58, p = 0.02) revealed that the players with longer training time had higher pulmonary function values. This study showed that regular wheelchair rugby training can improve the pulmonary function of subjects with spinal cord injuries.
本研究旨在探讨为期 1 年的常规轮椅橄榄球训练对四肢瘫痪患者肺功能的影响。共有 15 名男性四肢瘫痪患者参与了这项研究，他们被分为橄榄球运动员实验组（n=8）和久坐不动的四肢瘫痪对照组（n=7）。两组均进行了肺活量测定，实验组在参加为期 1 年的常规轮椅橄榄球训练计划前后进行了测试。在训练计划开始时，所有患者的肺功能与健康人群的预测值相比均有所下降（p<0.05）。经过 1 年的常规轮椅橄榄球训练后，用力肺活量（FVC）、1 秒用力呼气量（FEV1）和最大自主通气量（MVV）等指标均显著增加（p<0.05）。总训练时间与肺活量（r=0.97，p<0.0001）和最大自主通气量（r=0.58，p=0.02）之间的回归分析表明，训练时间较长的运动员肺功能值较高。本研究表明，常规轮椅橄榄球训练可以改善脊髓损伤患者的肺功能。
