简要总结
Immediately following a spinal cord injury (SCI), patients are admitted to inpatient rehabilitation where they undergo physical reconditioning in preparation for a return to home setting. The current standard of practice for aerobic training is performing arm-ergometry for 25 mins at a frequency of three times per week. Given the move towards shortened length of stay during inpatient rehabilitation, performing MICT can consume a considerable amount of therapy time. Sprint interval training (SIT) has been shown to elicit similar improvements in physical capacity, despite a reduced time commitment to MICT. However, there are no controlled trials comparing the effects of SIT to MICT in individuals with SCI undergoing inpatient rehabilitation. The primary aim of this study was to investigate the efficacy of a five-week, thrice weekly 10 min SIT program and compare outcome measures to a traditional 25 minute MICT program on the arm-ergometer in individuals with SCI undergoing inpatient clinical rehabilitation. It was hypothesized that five weeks of SIT and MICT would induce similar changes in maximal and sub-maximal exercise performance, self-efficacy for exercise, and exercise enjoyment, despite large differences in training volume and time commitment. It was also hypothesized that SIT would be well tolerated and elicit higher levels of cardiovascular strain than MICT.

研究组 & 干预措施
Moderate Intensity Continuous Training
Training was performed three times a week for five weeks. Each session began with a 2 minute warm up, and concluded with a 3 minute cool down. Following the warm-up, participants performed 20 minutes of arm cycling at a self-selected cadence at 45-65% of their peak power output. Total training duration was 25 mins.
干预措施: moderate intensity continuous training (Other)
Sprint Interval Training
The SIT protocol was adopted from Gillen and colleagues (See Ref), and consisted of 3 x 20 second "all-out" efforts at ≥ 100% of an individuals peak power output. Each sprint was interspersed by 120 seconds of active recovery at 10% of an individuals peak power output. Total training duration was 10 mins.

结局指标
主要结局
Change in peak power output
时间窗: Change in peak power output from baseline to 5 weeks
maximum amount of power produced during a graded exercise test on the arm-ergometer
Change in sub-maximal arm-ergometry
时间窗: Change in sub-maximal arm-ergometry from baseline to 5 weeks
Participants performed three 5-minute steady state workloads on the arm-ergometer at power outputs corresponding to RPE's of 8, 10 and 12. Participants were given a minimum of 2 minutes, and a maximum of 5 minutes of rest in between each workload.
