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

Detailed 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.

Eligibility criteria: Inclusion Criteria:

* Graduate students,
* Age between 18 to 30 years
* Healthy men, the Physical Activity Readiness Questionnaire (PAR-Q) was used to determine safety and possible risk of exercising based on participants' health history, the according American College of Sports Medicine, 2010.
* Trained men, the International Physical Activity Questionnaire (IPAQ) was used to determine participants' physical activity level.

Exclusion Criteria: Participants who did not attend all the RT protocols and those with HR record with error higher than 5% (ectopic beats) will be excluded.
