If you think that running marathons will help you live a long and healthy life, new research may come as a shock. According to a recent scientific study, people who do very strenuous1 activities are as likely to die as people who do no exercise at all.
 
Scientists in Denmark have been studying over 1,000 joggers and non-joggers for 12 years. The death rates from the sample group indicate that people who jog at a moderate pace two or three times a week for less than two and a half hours in total are least likely to die. The best speed to jog at was found to be about 5 miles per hour (8km/h).
 
The research suggests that people who jog more than three times a week or at higher speeds of over 7mph (11km/h) die at the same rate as non-joggers. The scientists think that this is because strenuous exercise causes structural2 changes to the heart and arteries3. Over time, this can cause serious injuries.
 
Peter Schnohr, a researcher in Copenhagen, said, "If your goal is to decrease risk of death and improve life expectancy4, jogging a few times a week at a moderate pace is a good strategy. Anything more is not just unnecessary, it may be harmful."
 
The implications of this are that moderate forms of exercise such as tai chi, yoga and brisk walking may be better for us than 'iron man' events, triathlons and long-distance running and cycling. According to Jacob Louis Marott, another researcher involved in the study, "You don't actually have to do that much to have a good impact on your health. And perhaps you shouldn't actually do too much".
