High-intensity interval training, solutions to the programming puzzle: Part I: cardiopulmonary emphasis.
Level 5 - mechanism / opinion, no new human data
Narrative review and expert programming framework without systematic review methodology

What was done
This narrative review analyzed high-intensity interval training (HIT) programming strategies, focusing on cardiopulmonary adaptations and methods to maximize time spent at or above 90% of maximal oxygen uptake (VO2max).
What was found
The abstract reports no empirical data, sample sizes, or pooled quantitative results. It identifies nine distinct programming variables (work interval intensity, work interval duration, relief interval intensity, relief interval duration, exercise modality, number of repetitions, number of series, between-series recovery duration, and between-series recovery intensity) that determine acute physiological responses and help maintain time spent in the targeted training zone (>=90% VO2max).
Why it matters
It outlines a comprehensive, mechanistic framework for coaches and sport scientists to systematically adjust interval parameters to target specific cardiovascular adaptations.
Limits
As a narrative review, it presents conceptual models and expert commentary rather than novel empirical data or a systematic review with meta-analysis. No effect sizes, participant characteristics, or risk-of-bias evaluations are provided.
