Effects of High Intensity Interval Training (Hiit) on Cardiovascular Diseases

Abstract

High-intensity interval training is easier to stick with and perform in cardiac rehabilitation due to its short-term high oxygen-consumption activity interphased with intervals of low-intensity training or rest for recovery. Time-efficient high-intensity interval training (HIIT), rather than guideline-based moderate-intensity continuous training, has been studied as an exercise training program in complete cardiac rehabilitation. According to research, high-intensity exercise improves aerobic and metabolic performance by stimulating the cardiopulmonary system and skeletal muscles more. In this small study, we looked at the risk factors for cardiovascular disease, improving cardiovascular health through exercise and high-intensity interval training (HIIT), and heart failure and HIIT. High-intensity interval training (HIIT) has been identified as an effective exercise protocol for general health and primary and secondary cardiovascular prevention using short exercise sessions. Given the variety of HIIT protocols, which can be divided into aerobic HIIT and anaerobic HIIT [usually referred to as sprint interval training (SIT)], health-care professionals such as primary care physicians and cardiologists may struggle to select an appropriate protocol for their patients. High-intensity interval training (HIIT) has emerged as a potentially beneficial alternative, involving brief bursts of high-intensity exercise interspersed with periods of rest, with the goal of increasing cardiovascular exercise intensity in a time-efficient manner. Understanding HIIT protocols and implementing the appropriate type for each participant would result in better VO+ peak improvements with higher adherence and lower risk.
