The objective of this study was to analyze the impact of different modalities and intensities of exercise training on cardiac remodeling started early after experimental myocardial infarction (MI). Male Wistar rats, weighing 200–250 g, were subjected to experimental MI. After 5 days, the animals were allocated into three experimental groups and observed for three months: S (sedentary control animals), C (animals subjected to continuous low-intensity training), and HIT (animals subjected to high-intensity interval training). Low-intensity exercise training was performed at a treadmill speed corresponding to 40% VO2 max, which was kept unchanged throughout the entire session (i.e., continuous low-intensity training). High-intensity interval training was performed in such a way that rats run during 3 min at 60% VO2 max, followed by 4-minute intervals at 85% VO2 max (i.e., high-intensity interval training). After the follow-up period, we studied hypertrophy and ventricular geometry, functional alterations in vivo and in vitro, oxidative stress, apoptosis, and cardiac energetic metabolism. Our data showed that both high-intensity interval and continuous low-intensity modalities improved cardiac energetic metabolism variables in comparison with sedentary infarcted animals. In addition, high-intensity interval training decreased cardiac oxidative stress, associated with improved diastolic function. On the other hand, the continuous low-intensity group showed impairment of cardiac function. Therefore, altogether, our data suggest that high-intensity interval training could be the best modality for early physical exercise after MI and should be better studied in this clinical scenario.

Objectives: To determine the effects of high intensity interval training (HIIT) or moderate intensity continuous exercise (MICE) in patients with myocardial infarction (MI). Background: Cardiovascular diseases are the leading cause of mortality and morbidity globally causing a significant reduction in the quality of life of these patients. Participation of these patients in rehabilitation programs which involve a significant component of exercise seems to help by improving functional capacity and quality of life (QoL). Despite the beneficial effect of exercise, the type of exercise that yields the best results is yet to be determined.Methods: Three databases (MEDLINE, CINHAL and SportDirect) were searched in May-June 2017 for original articles regarding the effect of two types of exercise in patients with myocardial infarction. Randomized control trial studies which enrolled patients with myocardial infarction and studied the effects of HIIT and/or MICE, were included in this review. Data were extracted and summarised and all studies were assessed for bias.Results: Both forms of exercise seem to improve the relevant outcome measures such as functional capacity, QoL, walking distance, fatigue and function of the left heart. However HIIT seemed to be better in comparison with MICE in improving these outcomes. Several limitations and risk of bias have been identified and reported.Conclusion: Both HIIT and MICE are recommended for patients with MI. Further research is required to conclusively support the superiority of HIIT over other types of exercise.

High-intensity interval training (HIIT) has many known physiological benefits, but research investigating the psychological aspects of this training is limited. The purpose of the current study is to investigate the affective and enjoyment responses to continuous and high-intensity interval exercise sessions. Twenty overweight-to-obese, insufficiently active adults completed four counterbalanced trials: a 20-min trial of heavy continuous exercise and three 24-min HIIT trials that used 30-s, 60-s, and 120-s intervals. Affect declined during all trials (p < .05), but affect at the completion of trials was more positive in the shorter interval trials (p < .05). Enjoyment declined in the 120-s interval and heavy continuous conditions only (p < .05). Postexercise enjoyment was higher in the 60-s trial than in the 120-s trial and heavy continuous condition (p < .05). Findings suggest that pleasure and enjoyment are higher during shorter interval trials than during a longer interval or heavy continuous exercise.

Objective: We aimed to determine the cardiorespiratory responses during, and adaptations to, high-intensity interval training (HIIT) prescribed using ratings of perceived exertion (RPE) in patients after myocardial infarction (MI) during early outpatient cardiac rehabilitation (CR).Methods: We prospectively recruited 29 MI patients after percutaneous coronary intervention who began CR within 2 weeks after hospital discharge. Eleven patients (seven men; four women; age: 61 ± 11 yrs) who completed ≥24 supervised HIIT sessions with metabolic gas exchange measured during HIIT once weekly for 8 weeks and performed pre- and post- CR cardiopulmonary exercise tests were included in the study. Each HIIT session consisted of 5–8 high-intensity intervals [HIIs, 1-min RPE 14–17 (Borg 6–20 scale)] and low-intensity intervals (LIIs, 4-min RPE &lt; 12). Metabolic gas exchange, heart rate (HR), and blood pressure during HIIT were measured.Results: The mean oxygen uptake (V˙O2) during HIIs across 88 sessions of HIITs [91 (14)% of V˙O2peak, median (interquartile range, IQR)] was significantly higher than the lower limit of target V˙O2 zone (75% of V˙O2peak) recommended for the HII (p &lt; 0.001). Exercise intensity during RPE-prescribed HIITs, determined as %V˙O2peak, was highly repeatable with intra-class correlations of 0.95 (95% CI 0.86– 0.99, p &lt; 0.001). For cardiorespiratory adaptations from the first to the last session of HIIT, treadmill speed, treadmill grade, treadmill power, V˙O2HII, %V˙O2peak, and VE during HIIs were increased (all p &lt; 0.05), while no difference was found for HR, %HRpeak and systolic blood pressure (all p &gt; 0.05). V˙O2peak increased by an average of 9% from pre-CR to post-CR. No adverse events occurred.Conclusion: Our results demonstrate that HIIT can be effectively prescribed using RPE in MI patients during early outpatient CR. Participation in RPE-prescribed HIIT increases exercise workload and V˙O2 during exercise training without increased perception of effort or excessive increases in heart rate or blood pressure.
