High intensity interval training of VERY short duration (5-10 seconds duration of the interval)has been shown to: A)Improve the maximal capacity of the ATP/PC system without improving VO₂ max. B)Improve the maximal capacity of the glycolytic system without improving VO₂ max. C)Improve VO₂ max and increase mitochondrial density in the trained muscles. D)None of the above answers are correct

Question

Quizplus · Accepted Answer

High intensity interval training (HIIT) of very short duration primarily targets the ATP/PC system and the glycolytic system due to the short duration of effort, which does not typically lead to improvements in VO2 max or increase mitochondrial density in the trained muscles. These adaptations are more associated with longer duration aerobic or longer HIIT efforts. Therefore, none of the provided options accurately describe the effects of very short duration HIIT.
