: Cardiovascular diseases (CVD) are the primary causes of death throughout the world. Engaging in physical activity (PA) is crucial for the prevention of CVD, as a lack of exercise significantly impacts global health. For health promotion purposes, it is important to optimize PA and develop the main physical components. Multimodal exercise program (MEP) interventions cause unique cardiac changes that can be systematically analyzed using advanced ECG techniques. Using algebraic co-integration methods, this study examined the physiological cardiac adaptations of a 6-week MEP compared to sedentary control subjects. : A total of 50 physically inactive males, aged 20-35 years, were recruited for a 6-week MEP. The intervention group (IG) consisted of 28 participants, while the control group (CG) included 22 participants. The MEP included balance, endurance, muscle strength, and flexibility exercises in one session. The cardiovascular system (CVS) was assessed using electrocardiography (ECG) and arterial blood pressure during an incremental cycle ergometer test, both before and after the 6-week period. : After the post-MEP, the IG's resting HR showed a slight but insignificant decrease, from 84.5 to 82 bpm, with improved recovery rates at minute 1 (113.1-104.7 bpm). The CG showed a similar trend. pBP in IG significantly increased post-MEP during recovery at minute 1 (73-81) and minute 2 (65-72), where the CG showed a slight but significant difference. DskJT-QRS in IG post-MEP increased significantly during recovery in minutes 1-4, with all values showing < 0.05. CG showed significance only at minute 3. : Both the 6-week MEP and control had a positive impact on the CVS. The statement refers to changes in dynamic interactions between ECG parameters registered during the incremental exercise test and especially during the recovery after workload. Algebraic data co-integration analysis of ECG parameters demonstrated a sensitive assessment of the influence of exercising on the cardiovascular system.
心血管疾病（CVD）是全球主要的死因。进行体育活动（PA）对预防心血管疾病至关重要，因为缺乏运动对全球健康有重大影响。为了促进健康，优化体育活动并发展主要身体成分很重要。多模式运动计划（MEP）干预会引起独特的心脏变化，可使用先进的心电图技术进行系统分析。本研究采用代数协整方法，比较了6周多模式运动计划与久坐对照组受试者的心脏生理适应性。
共招募了50名年龄在20 - 35岁的缺乏体育活动的男性参与为期6周的多模式运动计划。干预组（IG）由28名参与者组成，而对照组（CG）包括22名参与者。多模式运动计划在一次训练中包括平衡、耐力、肌肉力量和柔韧性练习。在为期6周的前后，通过递增式自行车测力计测试，使用心电图（ECG）和动脉血压评估心血管系统（CVS）。
多模式运动计划结束后，干预组的静息心率略有下降但不显著，从84.5次/分钟降至82次/分钟，第1分钟的恢复率有所改善（从113.1次/分钟降至104.7次/分钟）。对照组呈现类似趋势。干预组的收缩压在多模式运动计划结束后的恢复过程中，第1分钟（从73升至81）和第2分钟（从65升至72）显著升高，而对照组有轻微但显著的差异。干预组在多模式运动计划结束后的第1 - 4分钟恢复过程中，离散度JT - QRS显著增加，所有值均显示<0.05。对照组仅在第3分钟有显著变化。
为期6周的多模式运动计划和对照组对心血管系统均有积极影响。该陈述指的是在递增运动测试期间，尤其是在负荷后恢复期间记录的心电图参数之间动态相互作用的变化。心电图参数的代数数据协整分析证明了对运动对心血管系统影响的敏感评估。
