Clinical Trial Summary

To analyze the autonomic behavior in recovery post-acute resistance exercise performed in different intensities and body segments.

Description:

Resistance training (RT) is recommended to people with different health condition. RT is recognized as safe and effective method of increasing muscle strength, physical fitness, muscle mass, and overall cardiovascular health. The magnitude of the RT effects is associated with the structure of the training program. Understanding these aspects may provide guidance for the RT prescription while reducing potential risk of cardiovascular events associated with the recovery period after exercise. The objective of the study is to compare the acute responses of the Autonomic Nervous System post RT performed with different intensities (endurance and strength) in different body segments (UL and LL). Our hypothesis is that different intensities and body segments influence the acute responses of the ANS in the post RT recovery period.
