    Dear Editor,

    I thank Dr. Batacan et al. for their excellent meta-analysis “Effects of high-intensity interval training on cardiometabolic health” in the March 2017 issue of the British Journal of Sports Medicine [1]. Even if the effects of high-intensity interval training (HIIT) on inflammation are still unclear, research in the coming years will hopefully prove more positive benefits. For example, two recent studies showed effects through a long-term HIIT (12 weeks or more) in the inflammatory profile of overweight/obese adults, such as decreased interleukin (IL) 6, and increased IL-10 concentrations [2, 3].

    But regardless of the various health effects of HIIT, I think the following fact is also worth mentioning for consumers. Health is a motivation to start with regular exercise, but mostly no motive to stay in the long term. On a permanent and regular basis, sport is only practiced when factors such as pleasure and enjoyment are added to the movement. Therefore, I am especially pleased that even overweight/obese teenagers and adults feel HIIT for an enjoyable and time-efficient form of exercise, as several recent studies demonstrate [4-8].

    To Dr. Batacan and colleagues: Very well written, correct results, and appropriate references. Congratulations!
