Cardiovascular diseases (CVD) are the leading cause of death in the world.
Available studies support the role of comprehensive cardiac rehabilitation (CR) in patients
with heart disease, decreasing the death rate, morbidity, disability,
improving the quality of life of patients, being defined as a guided program to
training on the importance of health care, including diets, medication
and exercise routines. For the exercises used in cardiac rehabilitation it is necessary
avoid over training in patients, which is measured according to the level of fatigue.
Measuring fatigue during exercise is a highly used process in rehabilitation
physical.
Currently, the way to quantify fatigue is done using the Borg scale (effort
perceived by the patient), which depends largely on the patient's criteria. By
On the other hand, a more accurate method is the measurement of the level of blood lactate, which implies
An invasive measure.
The objective of this project is to implement a new portable and low-cost method
to monitor patients during physical therapy avoiding overtraining of the
same. The project is divided into 5 stages: the first is based on the literature review to
the development of the state of the art, which is focused on methods of estimating fatigue, in the
second stage will be carried out the development of the necessary protocol for the implementation
That is the third stage. For the fourth stage with the information collected from the tests is
necessary to process the data to which a statistical analysis will be done, being
This is the last stage.
This document presents the development of new monitoring methods for
fatigue-related parameters, such as support in physical rehabilitation sessions,
In this work a preliminary evaluation of gear parameters is carried out, such as: speed
step, angle of hip and knee movement, which show a decrease
progressive as physiological and subjective measures such as blood lactate and
Borg scale increase, demonstrating its relationship with fatigue caused by an exercise
physical that gradually increases in intensity.
As a result, the final protocol showed high functionality, where when monitoring
physiological parameters, these presented an increasing linear average behavior of the
Borg scale and blood lactate, in addition to having a decrease in electrical activity
muscle of the muscles most involved in gait, especially the tibial muscle
anterior and gastrocnemius. As for the kinematic parameters, the position of the center of
mass showed a greater variation as the intensity of the exercise increases, taking
a p value of 0.17 verifying the null hypothesis that dictates that, at greater fatigue, the movement
of the center of mass increases.
