- Abstract PURPOSE: To investigate the effects of high-intensity interval training (HIT) on physical fitness in youth with physical disabilities who 1) are able to run, 2) walk independently but are not able to run, and 3) propel a manual wheelchair. METHODS: A total of 70 children and adolescents were recruited from schools for special education in the Netherlands (mean age 13.4±2.9, range 8-19 years, 56% boys). The sample consisted of 35 runners, 24 walkers, and 9 wheelchair users. They had various physical disabilities; cerebral palsy (41%), spina bifida (8%), other neuromuscular diseases (34%), musculoskeletal (4%), cardiovascular (4%) and metabolic diseases (9%). HIT was performed for eight weeks, twice a week, containing 8-12 interval of 30 seconds all-out exercises followed by active recovery. Anaerobic performance was measured by the Muscle Power Sprint Test, agility with the 10x5 meter sprint test and a shuttle run/ride test (SRT) was performed to determine aerobic performance (shuttles) and VO2peak. RESULTS: Exercise attendance was 85%. Following HIT, anaerobic performance improved in both runners (p=.011) and walkers (p=.020), but not in wheelchair users (p=.463). Both agility and aerobic performance showed a significant training effect in all groups; runners (p=.001; p<.001), walkers (p=.024; p=.006) and wheelchair users (p=.024; p=.012). However, no changes were found for VO2peak (ml/kg/min) in any of the subgroups. CONCLUSION: Both anaerobic and aerobic performance improved in all subgroups after HIT, except for anaerobic performance in wheelchair users. No effects were found for VO2peak. For clinical practice, 30 seconds all-out intervals are feasible and safe in youth with physical disabilities. Future research should focus on wheelchair users specifically. To improve VO2peak short-term, we suggest for future research to increase training frequency to three times a week and/or increase time per interval (i.e. training volume).
