Forget about your anti-ageing creams and smoothies and whatever else you have. High intensity interval training (HIIT) is the true fountain of youth.
Ageing is an inevitable fact of life, but that doesn't mean that it can't be slowed. In fact, a study has found that it can even be reversible to some extent. Researchers have discovered that a particular form of exercise can re-energize you and make you more youthful.
HIIT is a fat-burning and muscle-building workout that can energize you right from the mitochondria, the powerhouse of the cell. Your mitochondria produce energy but slow down as you age, causing you to be more susceptible to fatigue. Ageing mitochondria also makes your muscles grow smaller as you get older. HIIT stimulates your mitochondria to produce more energy and even reverses their ageing process. Other benefits of HIIT include having a healthier heart and lungs.
When you undergo HITT, you're required to work out in short but physically-demanding bursts. You have short recovery periods of light exercise in between the intense workouts. This training technique is designed to make your body use more oxygen during the course of the intense training bursts. Your body will then work to gain more oxygen during the recovery periods. This causes your body to lose burn more calories and gain more musculature compared to other training programs.
Sreekumaran Nair and his colleagues at the Mayo Clinic discovered how HIIT affects the human body. For their experiment, they had two groups of people undergo HIIT for three months. One group's members were 18 to 30 years old, and the other group's members were 65 to 80 years old. The researchers also added some weight training to the regimen.
Before the training commenced, the researchers performed biopsies on the participants' muscles. The participants were then sent off to undergo their training.
When the participants came back from their training, the change was remarkable, especially in the older group. The post-training muscle biopsies revealed that both groups had significant improvement right down to their cells. The younger group exhibited that their mitochondria's energy output went up by 49%. The older group, meanwhile, exhibited an impressive 69% improvement in their mitochondria's energy output. In fact, HIIT seemed to have reversed mitochondrial decline in the older group.
HIIT also enabled the participants to have better lung capacity. The younger group was able to inhale 28% more oxygen, with the older group hitting 17%.
There have been a lot of anti-ageing products on the market over the years. Many of these products, especially the skin creams, are more concerned with making people look younger. While there's nothing wrong with that, being more youthful from inside out is far more beneficial. Taking the time for HIIT, which can be done anywhere, has long-term effects and improves the way your body works.
HIIT is something that's worth at least looking into. Even adults as young as 18 years old can benefit from the anti-ageing effects of this intense but rewarding regimen.
