Yes, exercise is good for the heart and the energy level – but how much do you really need to get the full benefit? And how long do you need to sweat it out to feel the difference? You’ll be happy to hear what Dr. Thijs Eijsvogels and Dr. Paul Thompson have to say on the issue.
They compared the results of various amounts of exercise and various exercises to try to answer these questions. They found that the smallest amount of exercise that will still make a difference in your health…is only about 105 minutes a week. This is a shocking amount compared to what the NHS guidelines suggest, recommending 150 minutes of moderate activity each week.
While the researchers did agree with the Danish research which suggested that increasing your exercise helped with mortality benefits – they found that doing more than 240 minutes a week had no added health benefits.
They explained, “We agree that any dose of exercise is better than physical inactivity and did not intend to discourage individuals from pursuing more exercise. Performance of vigorous exercise is an effective way to reduce the risk for cardiovascular morbidity and mortality. However, the dose-response relationship between exercise and cardiovascular health appears to be different for moderate-intensity vs vigorous-intensity activities.”
