OBJECTIVE/BACKGROUND:

There are still many gaps in research concerning the effect of different physical training modalities on sleep quality in the cardiac population. Thus, the objective of the present study was to compare the quality of sleep in subjects who underwent coronary artery bypass surgery submitted to two types of training (ie, aerobic exercise alone or combined aerobic and resistance training).

PATIENTS/METHODS:

80 Participants aged 45-65 years were randomized to two groups: aerobic group (AG), combined aerobic and resistance group (ARG). Training lasted ten consecutive weeks with 30 uninterrupted sessions. The actigraph (Actiwatch Minimitter Company, Incorporated (INC) - Sunriver, OR, USA) was placed on the non-dominant wrist and activities were monitored continuously while being recorded at one minute intervals. The participants kept the device for a period of 96 hours before the first and last training sessions.

Inclusion Criteria:

1. Patients who have underwent CABG surgery since 6-8 weeks
2. Their ages ranges from 40 and 80 years of age
3. Medically stable patients.
4. patients did CABG-only treatment (not combined with valve replacement surgery)
5. Current complaint of poor Sleep quality (SQ) (score > 5 of the SQ scale)
6. Body mass index ≤ 35 kg/m2 (no obstructive sleep apnea)

Exclusion Criteria:

1. Any patient is known to have any unstable medical condition
2. History of chronic insomnia for at least one year before surgery
3. Indication of receiving treatments for depression and anxiety
4. Musculoskeletal or neurological conditions that might interfere with the execution or the assessment of the exercise.
