Moving every 20 minutes can help heart patients prolong life

Washington D.C. [USA], Oct 22 (ANI): According to a new study, heart patients can prolong their life if they interrupt their sedentary lifestyle and move around every 20 minutes.
The study was presented at the Canadian Cardiovascular Congress (CCC) 2018. Visiting experts from the European Society of Cardiology (ESC) also participated in joint scientific sessions with the Canadian Cardiovascular Society (CCS) as part of the ESC Global Activities programme.
Heart patients spend most of their waking hours sitting, lying down, and watching television. Previous research has shown that being sedentary for long periods could shorten life but taking breaks to move around may counteract the risk, particularly if it means burning more than 770 kcal a day.
This study investigated how many breaks should be taken, and for what duration, if one needs to expend 770 kcal.
"Our study shows that heart patients should interrupt sedentary time every 20 minutes with a 7-minute bout of light physical activity. Simple activities such as standing up and walking at a casual pace will expend more than 770 kcal in a day if done with this frequency and duration," said study author Dr. Ailar Ramadi.
The study enrolled 132 patients with coronary artery disease. The average age was 63 years and 77% were males. Participants wore an armband activity monitor for an average of 22 hours a day for five days. The activity monitor recorded the amount of energy spent during breaks from inactivity, the amount of inactive time, and the number and duration of breaks during each sedentary hour.
"There is a lot of evidence now that sitting for long periods is bad for health. Our study suggests that during each hour of sitting time, heart patients should take three breaks which add up to 21 minutes of light physical activity. This will expend 770 kcal a day, an amount associated with a lower risk of premature death," added Dr. Ramadi.
Regarding limitations of the research, Professor Joep Perk, ESC Prevention Spokesperson, noted that this was a small, observational study with no control group.
"A randomised controlled trial is needed before this can become a firm recommendation. Nevertheless, regular physical activity is key to achieving a healthy life, whether you are a cardiac patient or not," he said. (ANI)
