The effect of resistance training on left ventricular function and structure of patients with chronic heart failure

The Effect of Short-Term Resistance Training on Heart of Nonathletic Healthy Male Students by Echocardiograph

“…This overload is a function of venous recession, volume of the ventricle and the decrease of heart sequence (44).the increase of LVEDd was probably due to the decrease in the resting intervals between training stations and the volume of training (the number of training stations) in any round of circuit weight trainings, as a result of which the cardiovascular system faced with the volume overload pattern in addition to the pressure overload, that probably increased the LVEDd in the present research. In the researches conducted by Kanakis and Hickson (1980), and Levinger et al (2005), it was found out that LVEDd does not change after resistance trainings that is inconsistent with the present research (17,23,26,28). Maybe the cause of inconsistency is the special type of resistance training that was used in the present study, because compared to previous studies, in this study, the number of training stations had increased, while the resting intervals between training stations had reduced and the nature of training program had become somewhat similar to strength-endurance trainings.…”

“…In past studies, the effects of resistance training on the heart of healthy people are examined (1,(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30). In some of the studies, it is stated that resistance trainings increase interventricular septum thickness, left ventricular posterior wall and Left Ventricular Mass Index (LVEDd) (17,18,20,21,(31)(32)(33).…”

“…In some of the studies, it is stated that resistance trainings increase interventricular septum thickness, left ventricular posterior wall and Left Ventricular Mass Index (LVEDd) (17,18,20,21,(31)(32)(33). However, some studies have also shown that long-and short-term resistance trainings can't have an effect on cardiac indexes including LVEDd, interventricular septum thickness, left ventricular posterior wall thickness, LVM, systolic performance and fractional shortening (24,26,28).…”

“…Although the effect of resistance training on skeletal muscles is known (26), the effect of these trainings on cardiovascular adaptations is inconsistent (28,35,36). However, several studies have examined the effects of short-term resistance training on the structure of the left ventricle (14,17,19,(26)(27)(28)30).…”

“…However, several studies have examined the effects of short-term resistance training on the structure of the left ventricle (14,17,19,(26)(27)(28)30). But no study is done about the effect of short-term resistance training on the structure of the left ventricle of Iranian nonathletic males.…”
