About this trial
Respiratory muscle training represents an effective method increasingly utilized in both sports and healthcare domains, employing various devices, among which threshold devices are prominent. The aim of this study is to determine the relationship between inspiratory muscle fatigue or warm-up and muscular strength in upper and lower limbs, in sedentary older adults, as well as the association between such fatigue and other variables, including maximal inspiratory pressure, diaphragmatic ultrasonography, functionality and handgrip strength.
According to our hypothesis, the execution of a protocol inducing inspiratory muscle fatigue or activation in sedentary older adults could influence muscular strength, respiratory function and exercise capacity.
In this study, subjects will be divided into three groups: the fatigue group , the activation group and the control group.
Measurements of variables, such as maximal inspiratory pressure, diaphragmatic strength (ultrasound image) and functional capacity, will be conducted.
