A recent research found that 30 minutes of moderate-intensity exercise a day is probably not enough for plenty of the millions of Americans with heart problems who practice it.
The research was published in the journal Circulation and it basically says that half an hour of exercising a day may not be enough to put you in great shape.
For the analysis, the group of researchers reviewed 12 prior studies that in total involved 370,000 participants of both genders, all ages and practicants of different physical activities. In the following 15 years, more than 20,000 participants had heart failure emergencies. All of them self-reported their weekly activities, which allowed researchers to precisely tell how much exercise they were doing during this period of time.
The team found that the participants who strictly followed the 30 minutes a day recommendations by the American Heart Associations only showed small reductions in developing heart failure compared to the participants who did not exercise or work out at all.
However, the team found that those who exercised for 60 or 120 minutes per day had a substantial reduction in developing heart failure, as much as 20% and 35%.
The results challenge the belief that a 30 minutes work out is enough for most people. The results showed that there is no limit to exercising, and that lower heart failure risks are dependent to the levels and periods of physical activity of the person. The association was verified across all age groups and races.
The author of the study, Jarett Berry, professor at the University of Texas, said that the research encourages health regulators to consider changing the current guidelines and offer people updated numbers in order to make exercising more effective against heart failure.
Heart failure is a widely spread condition in the United States, it affects more than 5 million adults per year and the healthcare costs are of about $30 billion. The condition occurs when the heart is incapable of supplying the body with enough blood.
Heart disease is responsible for a significant proportion of elderly deaths and hospitalizations in the United States. Worse, American healthcare officials estimate that the numbers are growing year after year, and it may increase up to 25% by 2030.
The study recommends people with heart risk failure to practice aerobic activity, mainly activities that make the patients breath faster and harder, making their heart beat faster. Some examples are: swimming, riding bikes on hills, basketball, jogging, single tennis etc. As for less intense activities, the government recommends: walking faster, riding a bike, double tennis, and water aerobics.
