Final answer:
High-intensity interval training leads to greater reductions in subcutaneous skin folds compared to steady-state endurance training due to its ability to increase metabolism and stimulate fat burning.
Step-by-step explanation:
The question is asking about the difference in the decrease of subcutaneous skin folds between high-intensity interval training and steady-state endurance training. High-intensity interval training is a form of exercise that involves short bursts of intense activity followed by periods of rest or low-intensity activity. Steady-state endurance training, on the other hand, involves maintaining a consistent level of activity for a prolonged period of time.
Research has shown that high-intensity interval training can lead to greater reductions in subcutaneous skin folds compared to steady-state endurance training. This is likely because high-intensity interval training is more effective at increasing metabolism and stimulating fat burning. Additionally, the intense nature of the exercise may lead to greater muscle activation and calorie expenditure.
For example, a study comparing the effects of high-intensity interval training and steady-state endurance training on subcutaneous skin folds found that after 12 weeks, the high-intensity interval training group had a significantly greater decrease in skin fold thickness compared to the steady-state endurance training group.
