About

Purpose: to investigate the hypothetical additive value of a sudden rest-exercise training over the cardiac vagal of cardiac patients in a supervised exercise program.

Full description

Allocating in the admission for a supervised exercise program all subjects evaluated with low cardiac vagal tone (cardiac vagal index ≤ 1,30), it is expected that from a sample of almost 150 subjects (all over 18 years-old, ranging mostly from 40 to 50), we will compare 50 subjects that adhered to the supervised exercise program ( more than 65% of expected presence). Patients with pacemaker on unable to exercise in the bicycle will be excluded from the study, as well as those who does not adhere to at least more than 65% of the expected presence in the supervised exercise program.

All the sample will be randomized to performed 8 weeks of a specific sudden rest-exercise training and after 8 weeks will discontinue the protocol, or will do the opposite ( 8 weeks of no specific protocol, followed by 8 weeks of specific sudden rest-exercise training). The cardiac vagal will be evaluated at every 8 weeks to measure the cardiac vagal index between both phases. During all the time, all clients will perform aerobic, strength and flexibility exercises as part of the supervised exercise program.

---

50 participants in 2 patient groups

Initiate with SEP but without RTTE

Active Comparator group

Description:

Initiate supervised exercise (SEP) program but without rest-exercise transition training (RTTE)to improve cardiac vagal tone at same time; will stop RTTE after 8 weeks.

Treatment:

Other: Supervised exercise program

Other: Supervised exercise program together with a specific sudden rest-exercise training protocol

Initiate with RETT and SEP

Active Comparator group

Description:

Supervised exercise program (aerobic, strength and flexibility exercises) and a specific sudden rest-exercise training protocol, three times a week. After 8 weeks, the sudden rest-exercise training protocol will be discontinued. The cardiac vagal index will be measured at every 8 weeks.

Treatment:

Other: Supervised exercise program

Other: Supervised exercise program together with a specific sudden rest-exercise training protocol
