The technological advancements in our modern times have changed the way we work. The World Health Organisation (WHO) reports that one of the causes of obesity is “an increase in physical inactivity brought about by the increasingly sedentary nature of many forms of work, changing modes of transportation, and increasing urbanization.” Furthermore, the organization reports that being overweight or obese causes the death of at least 2.8 million people every year; it is a major risk factor for various chronic diseases, including cardiovascular diseases, diabetes, and some cancers. As such, exercising has never been more relevant. Now it may be easy to say that it can help keep us healthy, so you may just take it for granted. But backing it up with scientific evidence might make you stop and really think about it; so, let us take a look at what the latest research says about exercise.
For longtime couch potatoes
Harvard Health reports that a study involving 53 healthy but sedentary middle-aged adults has found that those who did high- and moderate-intensity aerobic exercise four or more days a week for a couple of years saw significant improvements in their bodies’ use of oxygen; they also had less stiffness in the heart. So if you think that you have been a couch potato for too long and that there is nothing you can do to improve your health, then this study proves it otherwise.
For those with a high genetic risk of heart disease
Just because you have a high genetic risk of heart disease does not necessarily mean that you should give up on exercise. This is what researchers at the Stanford University School of Medicine have found, at least. Stanford Medicine reports that a study involving data collected from almost half a million individuals in the UK Biobank database, found that those with higher levels of grip strength, physical activity, and cardiorespiratory fitness have lower chances of having heart attacks and strokes; that’s regardless of their being genetically predisposed to heart disease.
For those with type 2 diabetes
A study has found that resistance training improves insulin management, the American Physiological Society reports. Those with type 2 diabetes can develop insulin resistance, which can result in the blood sugar spiking up to potentially dangerously high levels. Resistance training causes the muscles to increase in strength, tone, mass, and/or endurance.
That exercise can treat depression is well established, but its ability to prevent the mood disorder is not. But this might have just changed as a study, involving 33,908 Norwegian adults, has shown that regular exercise, even just for an hour, can prevent depression.
Regular exercise may not totally stop ageing, but it can slow it down. A recent study compared 125 amateur cyclists aged 55 to 79 to a group of adults of around the same age range who do not exercise regularly. And, it found that the group that exercised regularly (i.e. the cyclists) did not experience loss of muscle mass and strength. Additionally, their testosterone levels were high and their immune system was as good as that of a young person. For more information or equipment to get you on your way, visit EliteBodySquad.com.
