The purpose of this study was to evaluate the ability of individuals with spinal cord injury (SCI) to reach a training threshold during on-court sport activity. Monitors collected heart rate (HR) data every 5 s for 11 wheelchair tennis players (WCT) with low paraplegia and 11 able-bodied controls matched on experience and skill level (ABT). Average HR was determined for time spent in practice (e.g, drills) and game (i.e., a competitive set), and the ability to surpass 50% peak HR (HRpeak) and 64% HRpeak in each condition was evaluated. Average exercise intensity (%HRpeak) was not significantly different between the groups during practice (M WCT = 68.18, SD = 7.53%, M ABT = 68.78, SD = 5.44%; t = .22, p = .83) or game (M WCT = 68.17, SD = .17%, M ABT = 71.55, SD = 4.75%; t = 1.12, p =.28). Allparticipants averaged an intensity > or = 50% HR-peak during practice and game, and the difference between group participants averaging an intensity > or = 64% HRpeak was not significant during practice (chi2 = .92, p = .34) or game (chi2 = 3.85, p = .05). In terms of reaching a health and fitness training threshold during tennis, individuals with low-level SCI are similar to matched controls.
本研究的目的是评估脊髓损伤（SCI）患者在场上体育活动中达到训练阈值的能力。监测仪每5秒收集一次11名低位截瘫轮椅网球运动员（WCT）和11名在经验和技能水平上相匹配的健全对照者（ABT）的心率（HR）数据。确定了练习（如训练）和比赛（即一盘比赛）期间的平均心率，并评估了在每种情况下超过50%峰值心率（HRpeak）和64%HRpeak的能力。在练习期间（WCT组均值 = 68.18，标准差 = 7.53%，ABT组均值 = 68.78，标准差 = 5.44%；t = 0.22，p = 0.83）或比赛期间（WCT组均值 = 68.17，标准差 = 0.17%，ABT组均值 = 71.55，标准差 = 4.75%；t = 1.12，p = 0.28），两组之间的平均运动强度（%HRpeak）没有显著差异。所有参与者在练习和比赛期间的平均强度均≥50%HR-peak，并且在练习期间（卡方 = 0.92，p = 0.34）或比赛期间（卡方 = 3.85，p = 0.05），平均强度≥64%HRpeak的组间差异不显著。就网球运动中达到健康和健身训练阈值而言，低位SCI患者与相匹配的对照者相似。
