- Regardless of age, any kind of cardio or aerobic activity helps
you get stronger and fitter.
- Regular cardio workout maximizes the amount of oxygen in your
blood and increases blood flow to your muscles
- Starting exercise at an earlier age rather than later is
beneficial for the heart and well-being.
It's a known fact that regular exercise
such as walking, jogging, bicycling or swimming can help you live longer and healthier.
Regular exercise improves blood circulation, blood cholesterol levels, blood pressure and helps keep your weight under control
besides promoting enthusiasm and optimism. Exercise and physical activity boost your zeal for life and it's never too late to start it!
‘Physical inactivity is a modifiable risk factor for cardiovascular disease as well as other chronic diseases.’
However, a recent study demonstrates that introducing a structured physical activity or starting exercise late in your life does not reduce risk of heart disease
or help you live longer.
In a multisite trial that was
conducted, a total of 1635 sedentary people with an average age of 79 (30% with
histories of cardiovascular disease; 70% with at least one major cardiovascular
risk factor) were included. They were then randomized into either a structured physical-activity-intervention or
an education control group.
The physical activity intervention group did two exercise sessions weekly which were supervised. They also performed home-based activity three to four times weekly which included walking (goal, 150 minutes weekly) as well as strength training
Patients in the control group
attended weekly education sessions for a period of 26 weeks and monthly
For both the groups follow-up was done for an average of 2.6 years. At the end of the study, it was observed that there were no significant differences in rates of adverse cardiovascular (CV) events, myocardial infarction
or CV-related death between the groups.
Thus it was concluded that greater physical activity in
older individuals did not prevent adverse CV events and the authors thought
that this was because the intervention came too late in life. Another chain of
thought was that since the control group underwent education intervention, this
could have stimulated sufficient physical activity, thus minimizing differences
between the two groups.
The authors of the study commented, "The lack of association between physical activity and
reduced CVD found here should not detract from efforts to promote a program of
sustained walking and weight training in frail older adults."
The authors feel that there is a host of other benefits of starting exercise at an older age
such as preserving and improving mobility, which could be achieved without excess CV risk.
