“…There seems to be evidence that when used 3x/week, concurrent training is capable of generating increased physical capacity, in particular, promoting muscle hypertrophy. Published studies using this training methodology demonstrated significant increases in the crosssectional area and smallest diameters of the muscle fibers of rats, both in aquatic environments and soil exercises, with normal and hypercaloric diets (Castoldi et al, 2013;Machado et al;Castoldi et al, 2017).…”

“…The literature demonstrates that physical exercise is able to attenuate the emergence and development of several diseases, especially chronic degenerative diseases [ 37 – 39 ]. In addition, it is observed that physically active individuals may present better levels of quality of life [ 30 ], as well as increased physical capabilities [ 11 , 40 – 42 ].…”

Background The SARS-CoV virus is a precursor to the SARS-CoV-2 virus (COVID-19) and has caused millions of deaths worldwide. Although exercise can be a non-pharmacological means for the prevention and treatment of various diseases, the effects on COVID-19 patients are not yet completely clear. Aims The aim of this study was to investigate the relationship between physical exercise and symptoms caused by COVID-19. Methods The present systematic review was sent for evaluation and received the PROSPERO registration protocol-CRD42021257475. The search for studies related to health and physical exercise was carried out in the following databases; the “National Library in Medicine MEDLINE–Ovid”, “Embase”, “Web of Science”, “SportDiscus-Ebsco”, and “Scopus”. Results Ten articles were included in the systematic review and the findings demonstrated the protective effects of physical exercise in patients with COVID-19. These effects were observed both in symptoms and in the period of hospitalization. In addition, the results show that the benefits of physical exercise seem to collaborate both in an individual manner and as an alternative to drug therapy. Finally, it was possible to verify the effect of physical exercise on variables, such as quality of life, cardiorespiratory capacity, and immunological biomarkers, and on the symptoms of the new Coronavirus. Conclusions It is possible to conclude that physical exercise can be a component for the treatment of COVID-19. In addition, it could help to reduce the symptoms and severity of COVID-19, and may be considered as an adjunct to drug therapy in patients contaminated with SARS-CoV-2.

“…Aerobic training presents the ability to increase cellular organelles, such as mitochondria, improving the energy supply to the muscle (Castoldi et al, 2017a). In addition, other studies (Klemp et al, 2016;Ozaki et al, 2016;Schoenfeld et al, 2016) have demonstrated an anabolic effect through metabolic fatigue, in this way, the hypertrophy pathway would be triggered by this fatigue, not being dependent on the intensity/ load of the exercise (Fink et al, 2016).…”

The objective of the present study was to analyze the effects of four different training models, two aerobic and two anaerobic models, in relation to muscular hypertrophy, by means of morphometric analysis of the muscle cells of the soleus muscle and the extensor digitorum longus muscle (EDL). The animals were divided into five groups, control (C), aerobic training in swimming (ATS), resistance training in water (RTW), aerobic training on a treadmill (ATT), and resistance training in climbing (RTC). The aerobic training was performed at 70 % of the anaerobic threshold for 30 minutes, while the RTW was composed of 3 series of 10 jumps, and the RTC 4 series of climbs, both at 80 % of the maximum load. All training protocols were performed for a total period of 4 weeks, 3 times per week. The diameters of the muscle cells were measured by means of histological slides of the EDL and soleus muscles. For the EDL muscle, there was no difference between the ATS and ATT aerobic training models (p = 0.20). However, the RTW presented greater hypertrophy when compared to the RTC (p <0.01). Regarding the soleus muscle, the ATS was responsible for generating greater hypertrophy than the ATT (p <0.01). In addition, the RTC was more efficient at producing hypertrophy than the RTW (p <0.01). In this way, it was concluded that exercise adaptation was according to exercise type, aerobic or anaerobic, and not to the modality used.
