Effect of home-based high-intensity interval training versus moderate-intensity continuous training in patients with myocardial infarction: a randomized controlled trial

Abstract

Background Supervised high-intensity interval training (HIIT) has been proposed to be more effective than moderateintensity continuous training (MICT) for improving exercise capacity, but there are not sufficient information effects of home-based HIIT and MICT in patients with myocardial infarction (MI). Aims To compare the effects of home-based HIIT and MICT in patients with MI. Methods Twenty-one patients with MI were randomly assigned to one of two home-based exercise modes: HIIT group and MICT group. Home-based HIIT and MICT were performed twice a week for 12 weeks with an exercise intensity of 85-95% of heart rate (HR) reserve and 70-75% HR reserve, respectively. The primary outcome measure was functional capacity. Secondary outcomes included resting blood pressure and HR, peripheral oxygen saturation, pulmonary function and respiratory muscle strength, dyspnea severity, body composition (body fat%, body mass ındex (BMI), fat free muscle), peripheral muscle strength, and health-related quality of life (HRQoL). Results Functional capacity, measured by 6-minute walk test, increased in HIIT and MICT group (p < 0.05). Resting BP and HR, body fat%, and BMI were significantly decreased, and pulmonary functions, respiratory-peripheral muscle strength, and HRQoL were significantly increased in the both groups (p < 0.05). Home-based HIIT was more effective than MICT in improving pulmonary functions and lower extremity muscle strength (p < 0.05). Conclusions This study suggests that HIIT and MICT can be applied at home-based in patients with MI and play an important role in improving functional capacity, health outcomes, and HRQoL. Trial registration Clinical Trials Number: NCT04407624.

Putting It All Together: An Evidence-Based Guide to High-Intensity Interval Exercise Prescription for Patients With Complex Comorbidities

“…In addition, evidence shows that these programs are effective in varying clinical contexts, including home and intensive care units. [27][28][29] Low-volume, high-intensity interval exercise programs, although shorter in overall length, still improve overall function, strength, aerobic capacity, and physiological biomarkers. Overall training time is less than 15 minutes (not including warmup or cool down), and a starting interval time of 30 seconds has been recommended to provide increased flexibility for progression/regression in response to patient needs.…”

Adaptation of Teaching Strategies in Kinesiology Students to Obtain Reproducible and Reliable Data in the Assessment of Maximum Inspiratory Pressure

“…In the acquisition of experience by the team in charge of performing the evaluations, Rodríguez, in 2015 showed that an experienced evaluator has a regular to good reliability (intraclass correlation coe cient [ICC] = 0.70) [9]. On the other hand, Yakut et al, (2022) compared two home training protocols, one was a high-intensity interval training and the other was a moderate-intensity continuous training. In both groups, the MIP, functional capacity, and quality of life increased.…”

“…In both groups, the MIP, functional capacity, and quality of life increased. The researchers attributed these changes to the effect of learning the technique and the development of skills to perform the MIP, however, neither the form nor the time to acquire it was analyzed [10].…”
