Brief summary

COVID-19 survivors commonly exhibit a marked extra-respiratory complication affecting the cardiac (arrhythmias and myocardial injury), renal (acute kidney injury), gastrointestinal, nervous (neuropathy, encephalopathy), endocrine and musculoskeletal (weakness, pain, and fatigue) systems. In this context, several studies have found that resistance training intervention promotes important health-related benefits, including cardiac function, compared to aerobic exercise training. Other exercise adaptations include increased skeletal muscle metabolism function, yet physio/psychological adaptations are known to be limited in COVID-19 survivors. Hence, given that resistance training intervention is implemented in a manner that is tolerable to the individual patient, it may be a potential beneficiary personalized rehabilitation treatment for patients with COVID-19 syndrome ambulatory. The EXER-COVID Clinical Study project aims at determining the role of personalized exercise intervention in the treatment of post-COVID-19 syndrome ambulatory patients.

Detailed description

100 patients will be recruited and undergo baseline testing, including examination, immune systems, biochemistry markers, ECG, DXA, metabolic/respiratory function, VO2max, muscular fitness, lipidomic/inflammatory/oxidative markers and psychological outcomes. After baseline testing, participants will be randomly allocated into one group receiving standard of care (control group) or a group performing personalized resistance training intervention two times a week over a period of 6 weeks. The randomization procedure involves a computer-generated block randomization schedule in a ratio of 1:1 stratified by an independent person. Following the 8-week intervention period (with a 1-week washout period), both groups will complete a series of follow-up tests (as baseline testing). A 12-week follow-up experimental day is also planned in order to evaluate physio/psychological changes.

Interventions

BEHAVIORALResistance training

Participants will complete a 2-days-a-week training routine: Resistance training (RT, 50-75% 1RM (one-repetition maximum), 4 sets, 8-12 repetitions, 4 exercises). The warn up include Light Intensity Continuous Training (8-10 min, 65-70% HRR). Progressions will be individualized and consistent with patient tolerance. Sessions will be supervised by Physiotherapists and Graduated in Sports Sciences.

BEHAVIORALStandard care

This group will be allocated to standard care and therefore no supervised exercise regimen according to scientific guidelines for general physical activity and return to sport provided by the ACSM guidelines for Chronic Obstructive Pulmonary Disease and Cardiovascular Disease.
