A new report in the European Heart Journal suggests that people who partake in brief, but higher-intensity bursts of activity have a lower risk of many major health conditions, such as heart disease, stroke, dementia, and type 2 diabetes.
The study used wearable activity trackers to measure movement and estimate the participants’ total physical activity and its intensity. They found that even short periods of intense exercise, such as running for the train, can greatly reduce the risk of serious diseases.
In response to the findings, Dr Rupa Parmar, GP and Medical Director of Midland Health, is explaining that while these bursts of activity do have significant benefits, they shouldn’t replace regular exercise.
Dr Rupa Parmar said: “Higher-intensity exercise dramatically improves cardiorespiratory fitness, which is the marker for how well the heart, lungs, and muscles work together to supply and use oxygen during physical activity. Cardiovascular fitness is a key factor in how long we live well, as improving it can boost cell function and reduce the risk of chronic diseases.
“Short bursts of activity, such as running up the stairs, carrying heavy shopping bags, or anything that gets you out of breath, are important for cardiovascular fitness, have anti-inflammatory effects, and help our body metabolise fat and glucose. So, try adding them to your daily routine more regularly.
“However, while these short bursts really do have benefits, added up, they aren’t nearly enough to make up the 150 minutes of aerobic activity per week that is recommended, for good reason. Instead, maintaining a consistent exercise routine is essential for longevity and mobility. And it’s not just about physical health, regular and longer bouts of exercise are also important for mental well-being, as they’ve been shown to decrease stress, anxiety, and depression and improve cognitive performance, memory, and sleep quality.
“I’d recommend, instead of relying wholly on brief moments, to include vigorous exercise alongside a consistent routine of varied exercise, introduce bursts in small increments and gradually increase their frequency. Over time, it could lead to significant health improvements and help you reach that 150-minute weekly activity goal. Hopefully, you’ll soon notice an impactful difference in your physical and mental health.”
