Detailed Description
-----------------
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: aerobic exercise group<br>aerobic exercises (intervention) on treadmill for 10 weeks, 3 times/week for duration of 30-45 min/session. Exercise intensity is 50-65%of maximal heart rate (MHR) | Behavioral: exercise<br>* control group (n=40) did aerobic exercises on treadmill for 10 weeks experimental group (n=40) did combined aerobic and resisted exercises for 10 weeks<br>* Other names: cardiac rehabilitation;|
| Experimental: aerobic and resisted exercise<br>combined resisted and aerobic exercises (intervention) for 10 weeks (circuit weight training and treadmill training respectively) 2 times/week for a duration of 30-45 min/session Exercise intensity is 50-65%of maximal heart rate (MHR) for aerobic part and 50% of 1 repetition maximum (1RM) for resistance part. | Behavioral: exercise<br>* control group (n=40) did aerobic exercises on treadmill for 10 weeks experimental group (n=40) did combined aerobic and resisted exercises for 10 weeks<br>* Other names: cardiac rehabilitation;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| sleep quality to be assessed by Pittsburgh Sleep Quality Index (PSQI) | 1.The Pittsburgh Sleep Quality Index (PSQI) is a self-report questionnaire that assesses sleep quality over a 1-month time interval. | up to 12 months | 
| sleep fragmentation index to be assessed by actigraphy | 2.Actigraphy is a valid tool to assist in determining sleep patterns in normal, healthy adult populations, normal infants and children, and patients suspected of certain sleep disorders. | up to 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Functional aerobic capacity to be assessed by 6 minute walk test (6MWT) | The 6 Minute Walk Test is a sub-maximal exercise test used to assess aerobic capacity and endurance. The distance covered over a time of 6 minutes is used as the outcome by which to compare changes in performance capacity. | 6 months |
