[Comparison of the effects of selected aerobic continues and interval exercise trainning on heart rate rest and 1,2 and 3 minutes heart rate recovery of POST CABG patients]

ABSTRACT

Heart rate recovery [HRR] after exercise test and resting heart rate are shown to be important predicitive risk factors for cardiovascular and all-cause mortality in individuals with CVD. Therefore the purpose of this study is comparison of the effects of selected aerobic continues and interval exercise training on resting heart rate and heart rate recovery after 1,2 and 3 minutes in POST CABG patients. Twenty four POST CABG patients [22 men, 2 women with mean age 57.04 +/- 8.42 and mean BMI 27.17 +/- 2.98 kg/m2] were divided to a selected aerobic continues training, 30-60 min and intensity of 70-85% of HR maximum [n=12] and an aerobic interval training with three interval [9- 15 min], 27-45 min and intensity of 75-90% of HR maximum [n=12]. They perform the exercise protocols three times per week for 8 weeks. Result of pair T test showed, there are significant differences between pre and post resting heart rate after continues and interval training [respectively, p=0.034, p=0.013]. Continues and interval exercise training have significant effects on heart rate recovery in 1,2 and three minutes after exercise [continues; tl p=0.049, t2 p=0.033, t3 p=0.005. interval; tl p=0.033, t2 p=0.038, T3 p=0.018]. Also there are not any significant differences between the effect of continues and interval exercise training on resting heart rate [p-0.311] HRR [tl0.181, t2 0.885, t3953] after program. Both continuous and interval exercise training program improves resting heart rate and HRR minute's 1,2 and 3 in Post CABG patients and there are not any significant differences between two methods. This indicates the positive effects of exercise training on vageus tone and autonomic nervous system
