“…Respiratory muscle training (RMT) [40,42,43,45,46], skeletal muscle strength training [41,42,44,48] and aerobic training (AE) [41,42,44,48] were the exercise interventions performed in the included studies. Seven studies [41,42,[44][45][46][47][48] employed concurrent training as the intervention tool: RMT, strength training and AE [42,45,46] or AE and strength training [41,42,44,47,48]. The initiation of ThEx interventions occurred after overcoming the acute phase of SARS-CoV-2 infection [40][41][42][43][44][46][47][48], mild [42][43][44], moderate [40,47,48], severe/serious [41,46,48], in a period after SARS-CoV-2 infection of between 20 days [45] and 6 months [40].…”
