HIIT training highlighted for home workouts, heart rehab and HRV monitoring in Germany
High‑Intensity Interval Training (HIIT) involves short bursts of maximal effort followed by brief recovery periods, typically lasting 15–30 minutes. The format allows workouts to be performed at home without any specialised equipment, offering a time‑efficient way to improve cardiovascular fitness, calorie burn and the post‑exercise afterburn effect.
A systematic review and meta‑analysis of 22 randomised controlled trials with 1,364 participants compared HIIT to moderate‑intensity continuous training in patients with coronary artery disease. The analysis found that HIIT produced greater improvements in maximal oxygen uptake, six‑minute walk distance, maximal heart rate, diastolic blood pressure, left‑ventricular ejection fraction, end‑diastolic volume and systolic blood pressure.
Heart‑rate‑variability (HRV) monitoring, often expressed as RMSSD or its logarithm, reflects autonomic regulation of the heart and is used by some training apps to suggest recovery periods. While HRV can indicate recovery status, it is not a definitive fatigue sensor, and decisions based solely on HRV scores may unnecessarily cancel planned interval sessions.
