HIIT vs MICT

Introduction

The discussion regarding HIIT vs MICT has been very common in the current fitness world. The role of workout programs is essential for ensuring overall good health and improvement in cardiovascular function. Two types of popular workout techniques are known by the names of High-Intensity Interval Training (HIIT) and Moderate-Intensity Continuous Training (MICT). While both these workout types have a lot of advantages and benefits, yet scientists still study HIIT vs MICT in order to explore their impacts on mitochondrial biogenesis and cardiovascular health markers.

What Is HIIT in the HIIT vs MICT Comparison?

High Intensity Interval Training is a type of workout whereby one engages in workouts for 20-60 seconds and then rests. The exercise involves sprinting, cycling, body weight, among others.

It takes relatively less time compared to other forms of workouts. Nonetheless, one enjoys a lot of health benefits from HIIT workouts.

What Is MICT in the HIIT vs MICT Comparison?

The word MICT stands for continuous aerobic exercise performed in a low-to-moderate-intensity workout for a prolonged period. MICT includes exercise such as walking, jogging, cycling, and swimming for a period of at least 30 to 60 minutes. Without experiencing changes in the intensity of exercise.

HIIT and Mitochondrial Biogenesis:

Mitochondrial biogenesis is the process by which an organism produces mitochondria – organelles located in the cell which provide the energy needed to function. Mitochondrial development improves endurance, metabolic rate and helps prevent chronic diseases. The most recent evidence suggests that while MICT will also induce mitochondrial biogenesis through regular aerobic activity. The higher demand put on the body by HIIT results in a faster increase due to the involvement of signaling pathways. Such as PGC-1, in mitochondrial biogenesis. Despite the shorter time commitment associated with HIIT, it could achieve greater changes than MICT. However, MICT can still stimulate mitochondrial biogenesis and will improve mitochondrial function and endurance in the body, given enough time.

HIIT vs MICT for Mitochondrial Biogenesis

The list of indicators of cardiovascular health contains these items. Blood pressure, resting heart rate, VO 2 max, cholesterol levels and vascular function. Both HIIT and MICT have a positive influence on the indicators, however both training types differ.

In terms of HIIT it should be pointed out that it positively influences VO 2 max. Which is an important factor when judging cardiovascular health. VO 2 max influences the performance of the heart and lungs and determines the oxygen uptake and utilization by the body. Furthermore HIIT has a positive influence on insulin resistance which may lower risk of cardiac disorders.

In terms of MICT one must stress on a good influence on cardiovascular endurance. It is so because exercises of such kind effectively influence condition of the cardiovascular system and may prevent it from different diseases. Moreover MICT influences on maintaining body mass as well as it decreases blood pressure.

Which Is the better method?

HIIT and MICT training are very different in respect to preferences, fitness levels and health concerns. However, HIIT might be better suited for those seeking rapid improvements to their cardiovascular and mitochondrial performance. Whereas MICT is a type of exercise, an individual would want to be able to sustain, without injuring himself/herself.

The experts of this field suggest mixing the two types of training. This way an individual is able to produce both cardiovascular and proper mitochondrial effects with proper combinations.

Conclusion

The HIIT and MICT compared in terms of their effects on mitochondrial biogenesis and cardiovascular fitness variables, prove to possess great benefits. While the first seems to be a more time efficient and powerful way to improve mitochondrial fitness and cardiovascular fitness, MICT helps in steady improvements of cardiovascular fitness. Incorporating both of them into a training program would lead to both cardiovascular health and also better energy production.
