Influence of an Inspiratory Muscle Fatigue Protocol on Older Adults on Respiratory Muscle Strength and Heart Rate Variability
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 and maximal inspiratory pressure, diaphragmatic strength (guided by ultrasound image) and heart rate variability.

According to our hypothesis, the execution of a protocol inducing inspiratory muscle fatigue in older adults could influence cardiorespiratory function.

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, heart rate variability and diaphragmatic strength (ultrasound image), will be conducted.
