MELBOURNE: Its free, requires no equipment and the scenery can be stunning – its no wonder running is among the worlds most popular sports.
The number of recreational runners in Australia has doubled from 2006 to 2014. Now more than 1.35 million Australians (7.4 per cent of the population) run for fun and exercise.
Our study, published November 2019 in the British Journal of Sports Medicine, suggests running can significantly improve your health and reduce the risk of death at a given point in time.
And you dont have to run fast or far to reap the benefits.
Past research has found running reduces the risk of obesity, high blood pressure, high cholesterol, disability, type 2 diabetes, heart disease and cancer.
It also improves aerobic endurance, heart function, balance and metabolism.
These are important components of your overall health status. So, it would be reasonable to assume participation in running increases longevity. But the previous scientific evidence on this has been inconsistent.
Our review summarised the results of 14 individual studies on the association between running or jogging and the risk of death from all causes, heart disease and cancer.
Our pooled sample included more than 230,000 participants, 10 per cent of whom were runners. The studies tracked participants health for between 5.5 and 35 years. During this time, 25,951 of the participants died.
When we pooled the data from the studies, we found runners had a 27 per cent lower risk of dying during the study period from any cause compared with non-runners.
Specifically, running was associated with a 30 per cent lower risk of death from heart disease and a 23 per cent lower risk of death from cancer.
MORE ISNT NECESSARILY BETTER
We found running just once a week, or for 50 minutes a week, reduces the risk of death at a given point in time. The benefits do not seem to increase or decrease with higher amounts of running.
This is good news for those who dont have much time on their hands for exercise. But it should not discourage those who enjoy running to do it more often and for longer durations. We found even “hardcore” running (for example, every day or four hours a week) is beneficial for health.
Nor do the benefits necessarily increase by running at high speeds. We found similar benefits for running at any speed between 8 and 13 kmh. It might be that running at your own “most comfortable pace” is the best for your health.
BUT KEEP IN MIND THE RISKS AS WELL
Running may lead to overuse injuries. These occur as a consequence of repeated mechanical stress on the tissue without sufficient time for recovery.
A history of injury and a longer duration of activity increase the risk of overuse injuries.
You can minimise the risk by avoiding uneven or hard surfaces, wearing appropriate footwear, and not suddenly increasing the pace or duration of running.
There is always the risk of sudden death during exercise, but this occurs very rarely.
Importantly, we found that the overall benefits of running Read More – Source
