Sounds ludicrous, but when you consider the strain you place on your body when exercising, this really isn’t beyond the realms of possibility... is it? Granted, it is unlikely based on the thousands of previous studies that support the application of a regular exercise regime in staving off heart disease risk. However, new research led by Dr Nikola Drca of the Karolinska University Hospital, Stockholm, Sweden suggests that too much exercise i.e. more than 5 hours per week, by men in their 30’s increased their risk of atrial fibrillation (irregular heartbeat) compared to men who exercise a little less. However, this study contradicted itself a few times in that it also noticed that older adults who walked or rode an hour a day had a significantly lower risk of atrial fibrillation compared to those who didn’t perform such activity…so what do we believe, does it come down to the type and intensity of physical activity then?
This may well be one of those studies that instils fear into society, as well as giving less active people an excuse not to get out and exercise. Of course exercise has its place, there is little doubt that physical activity in some form is beneficial to the mind and body, but maybe this study raises new questions as to what is the ideal activity level and type for us humans. Whatever the verdict, I for one would find it practically impossible to limit the amount that I exercise a week, so lets hope this isn’t the case!
