High-Intensity Interval Training in Physical Therapy Beyond Cardiac Rehabilitation

Abstract

High-Intensity Interval Training (HIIT) has emerged as a significant intervention in physical therapy, extending beyond its traditional application in cardiac rehabilitation. This training method alternates short bursts of intense exercise with recovery periods, enhancing both aerobic and anaerobic capacities. Recent studies have demonstrated that HIIT not only improves cardiorespiratory fitness (CRF) but also positively influences cardiovascular health, particularly in patients with chronic conditions such as inflammatory arthritis and cardiovascular disease (CVD). In a clinical setting, HIIT has been shown to be safe and effective for various populations, including older adults and those with comorbidities. A structured 12-week HIIT program delivered in physiotherapy settings resulted in notable improvements in CRF and sustained benefits even after the intervention period. Moreover, HIIT has been associated with better adherence to exercise regimens and enhanced quality of life compared to moderate-intensity continuous training (MICT). The versatility of HIIT protocols allows for individualized adaptations based on patient needs and fitness levels, making it a valuable tool in physical therapy. As research continues to uncover the physiological benefits of HIIT, its integration into therapeutic practices is likely to expand, offering new avenues for rehabilitation and health promotion
