Influence of an Inspiratory Muscle Fatigue Protocol on Older Adults on Respiratory Muscle Strength, Muscle Oxygen Saturation, and Functional Capacity
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 diaphragmatic fatigue and muscular strength in upper and lower limbs, in both healthy and pathological subjects, as well as the association between such fatigue and other variables, including maximal inspiratory pressure, functionality and muscle tissue oxygen levels.

According to our hypothesis, the execution of a protocol inducing diaphragmatic fatigue in older adults could influence muscular strength, cardiorespiratory function, exercise capacity, and muscle tissue oxygenation.

In this study, subjects will be divided into three groups: the experimental group , the activation group and the control group.

Measurements of variables, such as maximal inspiratory pressure, peripheral muscle tissue oxygen levels, diaphragmatic strength (ultrasound image) and functional capacity, will be conducted.
