Effect of the physical conditioning in the cardiac frequency of rest and its variability in sedentary and practicing individuals of the masculine sort of physical exercises
The analysis of the variability of the cardiac frequency that it can indicate through the indices RMSSD, PNN50 and R-R average indices of the physical conditioning level of sedentary and trained individuals. The objective of this research is to evaluate the behavior of the Autonomic Nervous System (...

| Sumario: | The analysis of the variability of the cardiac frequency that it can indicate through the indices RMSSD, PNN50 and R-R average indices of the physical conditioning level of sedentary and trained individuals. The objective of this research is to evaluate the behavior of the Autonomic Nervous System (sympathetic and parasympathetic) through the variability of the cardiac frequency. For this the 14 volunteers who agreed to participate in the study, were divided in two groups, sedentary volunteers (n=7) and trained volunteers (n=7). The data were harvested with polar RS800 in order to analyze the RMSSD and PNN50 average indices and average R-R intervals, through the Polar Pro Trainer 5 Program. Results: The results were statistically analyzed through the t-student test. Conclusion: Even though the results have presented statistically significant difference only for the systolic arterial pressure, it was possible to observe a trend in the values of the percentiles for a cardiac frequency in rest, in the RMSSD, PNN50 and average R-R indices, indicating higher values of the cardiac variability of the trained volunteers in comparison with the variability of the cardiac frequency of the sedentary volunteers. |
