The aim of the study was to assess the effects of resistance training with the use of a suspension system on exercise tolerance, evaluated through an exercise test, and the changes in selected echocardiographic parameters of patients after myocardial infarction. The study involved 44 males. The subjects were divided into two groups: Standard (20) and Suspension system (24). All the subjects had undergone an angioplasty with stent implantation. The standard and suspension system groups carried out a 24-day improvement program comprising 22 training units. Each session consisted of endurance, general stamina and resistance training. Instead of resistance training, the experimental group made multijoint exercises with a suspension system. Statistically significant changes in both groups were observed in the parameters of the echocardiographic exercise test, such as test duration ( = 0.000), distance covered ( = 0.000), MET ( = 0.000), VO2max ( = 0.000) and SBPrest ( = 0.013). Additionally, SBPmax in the suspension system group improved ( = 0.035). The echocardiographic test revealed significant improvement of Left Ventricular Ejection Fraction in both groups (SP group = 0.001, standard group = 0.005). The lipid profile test in the SP group revealed statistically significant improvement of TC ( = 0.003), HDL ( = 0.000) and LDL ( = 0.005). Training with the suspension system had a positive effect on the change of exercise tolerance level, left ventricular function and blood lipid profile.
这项研究的目的是评估使用悬挂系统进行抗阻训练对运动耐量的影响，通过运动试验进行评估，以及心肌梗死后患者的超声心动图参数变化。研究纳入了 44 名男性。将研究对象分为两组：标准组（20 人）和悬挂系统组（24 人）。所有患者均接受过经皮冠状动脉介入治疗（支架植入术）。标准组和悬挂系统组均进行了为期 24 天的改善计划，包括 22 个训练单元。每个训练课程包括耐力、一般体力和抗阻训练。与标准组不同的是，实验组采用悬挂系统进行多关节运动。两组患者的超声心动图运动试验参数均发生了显著变化，包括试验持续时间（ = 0.000）、运动距离（ = 0.000）、代谢当量（ = 0.000）、最大摄氧量（ = 0.000）和静息收缩压（ = 0.013）。此外，悬挂系统组的收缩压最大值也有所改善（ = 0.035）。超声心动图检查显示两组患者的左心室射血分数均有显著改善（SP 组 = 0.001，标准组 = 0.005）。SP 组的血脂检查显示总胆固醇（TC）（ = 0.003）、高密度脂蛋白（HDL）（ = 0.000）和低密度脂蛋白（LDL）（ = 0.005）均有显著改善。使用悬挂系统进行训练对运动耐量水平、左心室功能和血脂谱的变化有积极影响。
