HEART FAILURE
Reduced tolerance to exercise is a symptom of heart failure (HF) and it is associated with increased disability and mortality [Individuals with HF show a 30% decrease in their ability to perform daily activities compared to healthy individuals, which is attributed to reduced muscular mass and decreased VOIn this context, functional training may be a potentially effective non-pharmacological therapy to increase physical function for individuals with HF. This modality of physical training consists of differentiated integrated movements of the body that involve joint acceleration and deceleration, stabilization, strength, and neuromuscular efficiency [In general, studies on functional training focus on assessing functionality in older adults based on walking capacity [
