Application of Cyclic Resistance Training Based on Theory of Planned Behavior in Patients with Chronic Heart Failure
Objective:To explore the application of cyclic resistance training based on theory of planned behavior(TPB)in patients with chronic heart failure(CHF).Method:A total of 93 CHF patients admitted to Sanming First Hospital from March 2022 to March 2023 were selected as experimental subjects.They were divided into control group(46 cases)and study group(47 cases)according to random number table method.The control group received conventional cyclic resistance training,and the observation group received cyclic resistance training based on TPB.The indexes of cardiac function,exercise tolerance indexes,physical fitness test indicators and quality of life before and after nursing were compared between the two groups.Result:After nursing,left ventricular ejection fraction(LVEF)increased,left ventricular end-diastolic diameter(LEVDD)and left ventricular end-systolic diameter(LVESD)decreased in both groups,LVEF in study group was higher than that in control group,and LVEDD and LVESD were lower than that in control group,the differences were statistically significant(P<0.05).After nursing,6-min walking test(6MWT),peak oxygen uptake volume(VO2peak)and anaerobic threshold(AT)were significantly increased in both groups,and 6MWT,VO2peak and AT in the study group were significantly higher than those in the control group,the differences were statistically significant(P<0.05).After nursing,the muscle strength of upper and lower limbs of the study group were higher than those of the control group,and flexibility of upper and lower limbs,lower limb balance and Minnesota living with heart failure questionnaire(MLHFQ)score were lower than those of the control group,the differences were statistically significant(P<0.05).Conclusion:In CHF patients,circulatory resistance training based on TPB can significantly improve cardiac function,exercise tolerance,functional fitness and quality of life.
