Shorter training time, same impact? Encouraging evidence for short-term, high-intensity interval inspiratory muscle training in chronic heart failure

The study by Wu et al., 1 with a robust methodological design, offers a valuable contribution to the literature by demonstrating that a shortterm (<10 min) home-based protocol based on high-intensity interval inspiratory muscle training (H-IMT) can significantly improve exercise capacity, inspiratory muscle strength, and quality of life in patients with chronic heart failure (CHF).
