Background: There are still many gaps in research concerning the effect of different physical training modalities on sleep quality in the population underwent coronary artery bypass graft (CABG) surgeries. Aims: The purpose of this study was to compare the effect of different exercise types on sleep quality and functional capacity after CABG. Methods: 46 Participants aged 45-65 years were randomized to two groups: aerobic group (AG), and combined aerobic and resistance group (ARG).Training lasted ten consecutive weeks with 30 successive sessions. The actigraph was used in sleep quality assessment. Six minute walk test (6MWT) was used in assessment of functional capacity. 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, and did 6MWT before the first and last training sessions. Results: there was significant decrease in the mean value of Sleep Latency, fragmentation index, light sleep duration scores (P <0.01) and significant increase in total sleep duration, deep sleep duration, number of cut points on the actigraphy, sleep efficiency and functional capacity in both (AG) and (ARG) (P <0.01), that difference was more significant in the aerobic group(AG)(P <0.01)
