A team of researchers in the US have recently claimed that high intensity interval training, otherwise known as HIIT, slows down the ageing process. A lot of times people say that exercise is the best medicine. Maybe it is true.
So what is HIIT? HIIT also known as high intensity interval training involves alternating between short bursts of very intense activities which is then followed lower paced exercise.
Sreekimaran Nair of the Mayo Clinic in Minnesota and his team assigned volunteers aged 18 to 30 and 65 to 80 to three months of weight training, interval training or a combination of the two. Muscle biopsies were taken before and afterwards in order to compare the impact of these activities on their cells. So does it really work? Well not exactly, you won’t actually stop aging.
According to the results, interval training helped boost the mitochondria (the powerhouse of the cell) in the cell’s ability to generate energy by 69 percent in older volunteers, while 49 percent in the younger group.
According to scientists, the mitochondria’s abilities decline as we get older however this decline was seen to be halted and even reversed in the older interval-training group. Surges in heart, lung and circulation health was also seen. The usual amount of oxygen they could inhale and exhale went up by 28% for the younger group and 17% for the older group.
The study also found that HIIT helps to restore the ribosomes in our cells. Ribosomes are the protein-building factories of our cells. It also boosts the capacity of the mitochondria, the powerhouse of the cell.
According to the results of the research the three types of exercise increased the lean body mass for both the younger and older groups. There was also an increase in insulin sensitivity which means that there will be a lower risk of getting diabetes.
So does this mean that you should immediately go and try HIIT? Well, it actually depends. Exercise is beneficial to you and your health. Whether you want to be healthy or just want to look good exercise will do you good. However, according to the research, the different types of exercise have different benefits. Weight training is said to be better at improving and developing muscle strength while HIIT helped boost mitochondrial activity. Also, it depends on the current state of your health. Before you try out an exercise regime like HIIT make sure that your trainer knows your medical conditions just to be safe.
