**Abstract**

Considerable advances in the poultry industry have been observed in the last sixty years. Consequently, new technological and biological processes have accompanied the development of animals and inputs. With these new possibilities and growth in the sector, there was also the emergence of new paradigms, one of which being the different types of myopathies. In the poultry industry, the breast is one of the noble parts and, therefore, a lot has been studied about the occurrences, alterations and/or different myopathies that alter its quality characteristics. Here we will highlight White striping (WS) and Wooden breast (WB), both investigated more recently due to changes in quality characteristics and considerable losses. The objectives of this review will be to discuss the biochemical parameters of these meats affected by myopathies WS and WB and their consequences on the development of skin, bone and intestinal microbiota lesions; correlate with the impacts of these occurrences to economic losses associated with partial and total condemnations of the carcasses. Another approach is that fast-growing animals have a drop in their quality of life, impacting the well-being of birds since the inflammatory process and excess weight have a direct correlation with dermatitis, corns, arthritis and other comorbidities.
