Acute and chronic effects of high-intensity interval and moderate-intensity continuous exercise on heart rate and its variability after recent myocardial infarction: A randomized controlled trial

Exercise-Based Interventions in Middle-Aged and Older Adults after Myocardial Infarction: A Systematic Review

“…The longest experimental program lasted 12 weeks in as many as seven studies [ 32 , 43 , 44 , 45 , 46 , 47 , 49 ], while the shortest was in the studies by Choe et al and Balsam et al, where the experimental program lasted four weeks [ 34 , 42 ]. The longest training session lasted 90 min [ 48 ].…”

“…The most monitored variables were VO 2 peak [ 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 41 , 42 , 44 , 46 , 47 , 48 , 49 ] and resting HR [ 30 , 31 , 32 , 33 , 35 , 36 , 37 , 39 , 41 , 42 , 43 , 44 , 45 , 48 , 49 ], followed by HRpeak [ 30 , 31 , 32 , 33 , 34 , 36 , 44 , 49 ]. The total exercise duration (utv) was monitored in six studies [ 37 , 38 , 39 , 41 , 42 , 47 ], while the metabolic equivalent (METs) was monitored in seven studies [ 30 , 31 , 34 , 39 , 42 , 43 , 46 ].…”

“…There were studies that had only one experimental and one control group [ 30 , 31 , 32 , 33 , 35 , 37 , 38 , 41 ], and there were studies that included participants who all underwent an experimental intervention [ 34 , 42 , 43 , 49 ]. In addition, there were studies with two experimental groups [ 36 , 39 , 45 , 46 , 48 ], and there were studies that had two experimental groups with a control group [ 40 , 44 , 47 ]. In nine studies, the physical activities of the experimental program were performed on a treadmill [ 30 , 31 , 32 , 33 , 36 , 39 , 42 , 43 , 44 ].…”

“…In nine studies, the physical activities of the experimental program were performed on a treadmill [ 30 , 31 , 32 , 33 , 36 , 39 , 42 , 43 , 44 ]. Two studies used a cycle ergometer [ 34 , 48 ], while the combination of treadmill and cycle ergometer was performed in seven studies [ 35 , 38 , 41 , 45 , 46 , 47 , 49 ]. Only one study used a combination of different physical activities (treadmill, cycle ergometer, rowing machine, and cross trainer) [ 37 ].…”

“…Most exercise-based intervention protocols consisted of aerobic training. On the other hand, there were types with high-intensity interval training (HIIT) [ 45 , 46 , 47 , 49 ], and also with moderate-intensity continuous exercise (MICE) [ 48 ]. Furthermore, one study compared high-intensity training (HIT) with moderate continuous training (MCT) [ 36 ]; therefore, a variety of protocols can be noted.…”
