Number of Sprint Repetitions in a Sprint Interval Training Session Does Not Moderate Improvements in V̇O2max With Training: A Systematic Review and Meta-Analysis.
Scandinavian journal of medicine & science in sports·July 1, 2026·PMID 42477971
Why it mattersClinicians prescribing exercise for cardiorespiratory fitness can use low-volume SIT protocols (fewer sprint repetitions) to achieve meaningful V̇O2max gains while improving time efficiency and potentially reducing negative affective responses, which may enhance adherence in physically inactive populations.
