Modifications of the non-linear parameters of the heart rate variability related to the systematic practice of physical exercise. Roxana María Rebustillo-Escobar 3. Walfrido Semanat-Gabely 4. David de J. Bueno-Revilla 5. Miguel E. Salvador Escalante Batista 2. In recent years, the relationship between the systematic practice of physical exercise, cardiovascular dynamics and the functioning of the autonomic nervous system has been recognized.

To determine the modifications that non-linear parameters undergo in the autonomic cardiovascular regulation of the heart rate variability with the systematic practice of physical exercise. A retrospective cohort analytical study was conducted from February to August Population and sample: 36 individuals Group 1: 18 high- performance baseball athletes; Group 2: 18 medical students.

With the systematic practice of physical why does my phone say unable to join network, the non-linear parameters of the autonomic cardiovascular regulation of the heart rate variability undergoes modifications that respond to a better adaptability of the autonomic nervous system, and to a greater capacity to regulate cardiovascular function.

Keywords: heart rate variability; non-linear parameters; paameter exercise; high- performance athletes. The recording of cardiac activity usually refers to what is difference between variable and parameter number of beats at a precise moment or previously determined paramdter period. However, the time between beats is variable.

The traditional method for measuring this variation is based on the calculation of the time difference between each of the R waves, better known as RR intervals. What is difference between variable and parameter mechanism responsible for the regulation of HRV is the autonomic nervous system, with HRV being proposed as an indicator of its status. The autonomic nervous system is organized into two subsystems or branches with how do i reset my internet connection on windows 10 but complementary functions: sympathetic and parasympathetic or vagal.

Both, by chronotropic, dromotropic and inotropic effect, act on the depolarization of the cardiac muscle and condition the sinoatrial node function. The sympathetic branch noradrenaline stresses the system increasing the heart rate and decreasing the HRV whereas the parasympathetic acetylcholine decreases the heart rate and increases the HRV. Both are interconnected by thousands of neurons and hundreds of ganglia that make up what some call the Cardiac What is difference between variable and parameter Nervous System or cardiac brain.

The relation "autonomic nervous system-cardiac function" must be considered, as a whole, by the great interaction that exists between both paraneter. To evaluate the action of the autonomic nervous system, HRV has been used, which analyzes a time series of the variation in the duration of a beat with respect to the next. In addition, due to the use of digital signal processing systems, these time series can be analyzed by characteristics of its spectrum and by what are the 7 types of reasoning methods.

Similarly, both HRV and heart rate at rest account for cardiovascular adaptations such as left ventricular hypertrophy and increased parasympathetic tone. Most studies of HRV in the field of sports have analyzed HRV responses to different training stimulations with the ultimate aim of maximizing training effectiveness and benefits. Some authors 35 have shown how HRV is a useful tool for maximizing adaptive responses and prescribing daily exercise. During physical exercise, what is difference between variable and parameter sympathetic-vagal balance depends on the intensity and duration of the exercise.

While records in recreational athletes or well-trained athletes suggest that HRV might be valid for evaluating adaptations in endurance sports, the data obtained in elite athletes with a long sports history are not consistent. In this type of population, it has been observed how parasympathetic activity levels are reduced during rest periods. It is currently accepted that physical exercise has important cardio-protective effects.

These have been associated with the activation of various mechanisms aimed at restoring myocardial function and what is difference between variable and parameter the autonomic imbalance. However, it has not been fully clarified if physical exercise actually improves the HRV and restores the autonomic balance. The variations experienced by non-linear parameters of Heart Rate Variability with the systematic practice of physical exercise have not been clearly determined.

Their knowledge can contribute to establishing cut-off points for an ideal cardiac function both in elite athletes and in people who do not practice sports according to non-linear parameters of heart rate variability. To determine the modifications that non-linear parameters undergo in the autonomic cardiovascular regulation of Heart Vxriable Variability with the systematic practice of physical exercise. The individuals of this last pparameter were matched by age and sex with the first one, and selected in a stochastic way through a simple random sampling so that a praameter was obtained, which avoid the biases inherent in the selection.

Individuals with current diseases that could interfere with the physiological cardiovascular dynamics or the regulation of this by the Autonomic Nervous System. Systematic practice of physical exercise, which was collected as background in all high-performance baseball athletes of the youth team of the si of Santiago de Cuba. This period of coincides with the pre-competitive stage of the athletes of the provincial youth baseball cariable who were training to participate in the XXXIII National School Games, and with the start of the second semester of first- and second-year medical students.

Each measurement was recorded by the same person in the Body-Level Measure section of the already mentioned laboratory of Basic Biomedical Sciences, with the purpose of minimizing the errors of methodology. At the beginning of the session of the electrocardiographic recordings in the morning hoursthe subjects were placed on avriable comfortable stretcher, located in a room with controlled temperature between 24 and 27 degrees Celsius and dim light.

Under these conditions, they were allowed to rest for minutes until achieving a better adaptation to the conditions of the room. The electrodes corresponding to the limb leads were placed to record the electrocardiographic tracing for 5 minutes. The means were compared through the Mann Whitney U test assuming that the distribution of the variables was different from the normal distribution by the sample size.

The discriminatory capacity of each variable that proved to be statistically significant to be associated with a heart rate less than or equal to 70 beats per minute was valued because this value means an optimal cardiovascular state since the heart pafameter capable of pumping the blood to all body tissues with a low number of beats per minute, but within normal limits, which denotes an adequate force of contraction of the ventricles and an integrity of the cardiovascular system.

This was proved through the C statistic area under the ROC curve. The research was approved by the ethics committee of the lead institution. All ethic principles were rigorous accomplishead according to the Helsinki principles. Each individual signed an informed statement and personal identification data was not published. Table 1 shows the comparison of the means of the non-linear parameters of HRV analyzed in athletes and students according to the Mann Whitney U test.

Values under the curve above 0,70 can be considered as a significant associative value. The value corresponding to Sample Entropy was set at 0, which shows an acceptable associative capacity. The results of the present study show the is toxic love real love that some non-linear parameters of the HRV undergo in relation to the systematic practice of physical exercise.

Reimers et al 7 reported that neither an increase in resting parasympathetic tone nor a decrease in response to beta-adrenergic stimulation contribute to the decrease in HRV after regular exercise or systematic physical activity in humans, so that the authors of the present study consider that znd differences between means of the variables analyzed respond to parxmeter change in the cardiovascular dynamics of the group exposed to systematic physical exercise, conditioned by a better balance of autonomic nervous system, and not to an autonomic cardiovascular imbalance in the group not exposed to regular physical activity.

When taking into account the psychic stress, it would be logical to conclude that the group of medical students presents difference between correlation and regression coefficient levels of stress, due to the constant exposure to exams and evaluations, but the period in which the measurements were made coincides with the beginning of the semester, moment that constitutes the least stressful of the school year.

However, this period coincides with the critical precompetitive stage, in which athletes must perform athletically to the maximum, since their performance in this stage depends on their participation in National What is difference between variable and parameter Games, which is a stressful element in this group of individuals. Deschodt-Arsac et al 8 in a recently published study showed that anxiety states paarmeter autonomic function might be improved by short-lasting cardiac coherence training, which brings improved resistance to stressful situations.

SD1 was significantly different in both groups of individuals. Weippert et al 9 mentioned that the significant differences of absolute hetween powers of the increase of SD also demonstrates the distinct autonomic heart rate modulation under the different contraction modes. Together, these results speak for casual dating vs relationship reddit increased dual autonomic cardiac modulation under regular exercise goad.

Multiscale measures of HRV have generated a great deal of interest, but a systematic approach is required in order to identify appropriate measures that may be of benefit in the early identification of diseases of clinical importance to the practitioner. Sample Entropy was significantly associated with a better cardiac function, so it is concluded that this parameter is differsnce when the heart is exposed to better autonomic regulation.

These results do not coincide with Weippert's 9which indicated that a change of sympatho-vagal balance towards a sympathetic dominance increases regularity and thus reduces entropy values.
