SIT may offer a time-efficient alternative to ET for eNOS gains in sedentary males; extends RCT evidence on exercise modality and microvascular adaptations.
Does sprint interval training improve muscle microvascular density and eNOS content compared to endurance training in sedentary males?
In sedentary males, 6 weeks of sprint interval training is as effective as endurance training in improving muscle microvascular density, and yields a greater increase in eNOS protein content.
