High-Intensity Interval Training (HIIT) has become increasingly popular in recent years due to its ability to burn fat and improve metabolic health in a shorter amount of time than traditional forms of exercise. But how exactly does HIIT impact metabolism and fat loss?
What is HIIT?
HIIT is a form of cardio exercise that involves short bursts of high-intensity exercise followed by periods of rest or low-intensity exercise. This type of training can be done with a variety of exercises such as running, cycling, or even bodyweight exercises like burpees or jumping jacks.
How HIIT Affects Metabolism
Metabolism refers to the chemical processes that occur in the body to maintain life. HIIT has been shown to increase metabolism both during and after exercise, also known as the afterburn effect or excess post-exercise oxygen consumption (EPOC). This means that even after the workout is over, the body continues to burn calories at an elevated rate.
In fact, a study published in the Journal of Translational Medicine found that HIIT increased metabolism by an average of 9% in participants who completed a 20-minute HIIT workout compared to those who did not exercise at all. This increase in metabolism can lead to greater fat loss over time.
HIIT and Fat Loss
When it comes to fat loss, HIIT has been shown to be more effective than steady-state cardio exercise. A study published in the International Journal of Obesity found that HIIT was more effective at reducing body fat in overweight individuals than moderate-intensity continuous training (MICT).
Additionally, HIIT has been shown to be effective at reducing visceral fat, which is the fat that surrounds internal organs and has been linked to an increased risk of chronic diseases such as heart disease and type 2 diabetes.
Overall, HIIT is a highly effective form of exercise for improving metabolic health and promoting fat loss. Its ability to increase metabolism and burn calories for hours after exercise makes it a time-efficient option for those looking to improve their health and fitness. So, if you’re looking to switch up your workout routine and get the most bang for your buck, give HIIT a try!
