The effect of high-intensity interval training and moderate-intensity continuous training on cardiorespiratory function in healthy elderly individuals: Systematic review and meta-analysis

Both HIIT and MICT effectively improve cardiovascular and pulmonary function in elderly individuals, with HIIT yielding more favorable results. MICT is suitable for long-term training in individuals with good tolerance, while HIIT is better suited for short-term interventions for those able to tolerate high-intensity exercise. In clinical practice, the appropriate training regimen should be selected based on individual health status.
