AB  - OBJECTIVE: To investigate the effect of stage duration on peak physiological 
      response to arm ergometry incremental exercise testing in individuals with spinal 
      cord injury or disease (SCI/D) in support of developing a more individualized 
      approach to testing. DESIGN: Parallel reliability study. SETTING: University 
      research laboratory. PARTICIPANTS: Individuals with SCI/D (N=38) performed 2 peak 
      oxygen consumption assessments comprised of 1-minute or 3-minute stages on 1 day. 
      INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Heart rate and oxygen 
      consumption were recorded continuously from baseline through recovery. Every 1 
      minute or 3 minutes, resistance increased at an individualized level, and 
      participants continued until volitional fatigue. The highest 30-second average 
      was selected as peak oxygen consumption (Vo(2)peak) and peak heart rate. The 
      highest workload achieved for >/=30 seconds was recorded as peak power output (PO). 
      RESULTS: Intraclass correlation coefficients (ICCs) were >.95 for the following 
      variables: absolute Vo(2)peak (mean +/- SD, 1min: 1.2+/-0.7, 3min: 1.2+/-.62L/min; 95% 
      CI, .91-.98), relative Vo(2)peak (mean +/- SD, 1min: 16.6+/-9.4, 3min: 
      15.8+/-8.0mL/kg/min; 95% CI, .90-.98), absolute peak PO (mean +/- SD, 1min: 61+/-41, 
      3min: 66+/-41W; 95% CI, .92-.98), and relative peak PO (mean +/- SD, 1min: .80+/-56, 
      3min: .90+/-.55W/kg; 95% CI, .91-.98). There was no significant difference in peak 
      heart rate between 3 minutes (132+/-27 beats per minute [bpm]) and 1 minute (130+/-28 
      bpm); however, the ICC lower limit was <.75 (0.67-0.90). Total test time was 
      significantly longer in the 3-minute (8:17+/-2:52min:s) than in the 1-minute 
      (6:29+/-2:21min:s) protocol. CONCLUSIONS: For measuring peak physiological values 
      in an incremental arm ergometry test, stage duration is of little consequence 
      because similar values were obtained for the main outcome measures in both 
      protocols.
