Sprint Interval Training During Rehabilitation After Spinal Cord Injury (SprintSCI)

October 15, 2018 updated by: McMaster University
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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: 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.
Other: moderate intensity continuous training
Participants utilized the arm ergometer for improving aerobic exercise capacity
Experimental: 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.
Other: Sprint interval training
Participants utilized the arm ergometer for improving aerobic exercise capacity

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in peak power output
Time Frame: 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 peak power output from baseline to 5 weeks
Change in sub-maximal arm-ergometry
Time Frame: 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.
Change in sub-maximal arm-ergometry from baseline to 5 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Cardiovascular Responses
Time Frame: Throughout each week of training (Week 1,Week 2, Week 3, Week4, Week 5)
Monitored heart rate throughout each training session
Throughout each week of training (Week 1,Week 2, Week 3, Week4, Week 5)
Perceptual Responses
Time Frame: Throughout each week of training (Week 1,Week 2, Week 3, Week4, Week 5)
Monitored ratings of perceived exertion throughout each training session
Throughout each week of training (Week 1,Week 2, Week 3, Week4, Week 5)
Change in self-efficacy for exercise
Time Frame: Change in self-efficacy from baseline to 5 weeks
Using a self-reported questionnaire, participants rated how confident they are with regards to performing and carrying out regular physical activities and exercises.
Change in self-efficacy from baseline to 5 weeks
Exercise Satisfaction
Time Frame: Measured only at the end of the intervention (5 weeks)
Participants completed the Physical Activity Enjoyment Scale (PACES) in order to asses the level of enjoyment with the training intervention they received.
Measured only at the end of the intervention (5 weeks)
Pain perceptions
Time Frame: Measured only at the end of the intervention (5 weeks)
Through a questionnaire, participants rated how much shoulder pain, bodily pain, and physical discomfort they typically experience throughout the day and how much pain they experienced with the intervention they were allocated to.
Measured only at the end of the intervention (5 weeks)
