Why the study?
Does high-aerobic intensity endurance interval training improve VO2max more than moderate training at lactate threshold or 70% HRmax?
Does high-aerobic intensity endurance interval training improve VO2max more than moderate training at lactate threshold or 70% HRmax?
High-intensity interval training yields greater improvements in VO2max and stroke volume compared to work-matched moderate-intensity training.
Answers are grounded in this paper and cite their sources.
High-intensity intervals may yield greater VO2max gains than work-matched moderate training; hypothesis-generating pending larger trials.
: High-aerobic intensity endurance interval training is significantly more effective than performing the same total work at either lactate threshold or at 70% HRmax, in improving VO2max. The changes in VO2max correspond with changes in SV, indicating a close link between the two.
