Aerobic Trainings on Stroke Patients

Effects of different exercise strategies on stroke patients remain unclear. Randomized controlled trial with concealed allocation has been performed from August 1, 2016 to June 30, 2018. We traced back 23 stroke patients, recruited during the above period, aged about 55 years with stroke duration \> 24 months . Intervention: 13 of them underwent 36 times of moderate-intensity continuous training (MICT) at 60% of peak oxygen consumption (VO2peak) for 30 mins, and 10 had high-intensity interval training (HIIT) at alternative 80% and 40% VO2peak with the same training times and duration. Outcome measures: VO2peak, cardiac output (CO), bilateral frontal cortex blood volume (∆\[THb\]), oxyhemoglobin (∆\[O2Hb\]) and deoxyhemoglobin (∆\[HHb\]), ventilation efficiency, serum brain-derived neurotrophic factor (BDNF) levels, cognitive and life quality questionnaire, percentage of neuroblastic cell bearing neurites (% neurites), and cell fluorescent staining were examined before and after interventions.
