[{"arm_notes": "", "treatment_id": null, "treatment_name": "A sample of 94 patients; 47 per group; was calculated considering a 95% confidence power with a margin of error of 5%; and a minimum effect size of significance of 0.3. The chosen effect size was based on two published controlled studies on the effect of physical intervention for post-COVID patients; which evaluated the effect of rehabilitation on functional outcomes and quality of life in this population. Finally; considering possible patient losses during the course of the study; we will invite and select 55 patients per group. The sample size calculation was performed in the GPower 3 software. Experimental group: After the evaluation procedures; for those randomized to the intervention group; the high intensity interval training will be performed. All the procedures of this group will be standardized and performed by qualified research physiotherapists; trained and with expertise in performing this type of exercise. The exercises will have a total duration of 38 minutes; including warm-up and conditioning. A 10-minute warm-up will be performed with a heart rate range between 60 and 70% of the maximum heart rate observed in the cardiopulmonary test. The intervals during each session will be 4 times with a duration of 4 minutes each; between 85% and 90% of peak heart rate. The intervals will be interspersed with 3 active breaks lasting 3 minutes each; between 50% to 70% of peak heart rate. The training session will end with a 3-minute cool-down between 50% to 70% of peak heart rate. Upon completion of the day's exercise session; the participant will be asked to sit down. The participant will only be released to go home after vital signs have been checked and no adverse events associated with exercise have been identified.
