A new study from Seoul University, South Korea, suggests that exercising over the age of 60 may significantly lower the risk of heart attack and stroke.
A team of researchers analyzed data taken from 1,119,925 men and women who were 60 years or older. These data were collected by the National Health Insurance Service (NIHS). The average age of the participants was 67 years, and 47% of them were male.
The analysis showed that people with increased levels of physical activity to moderate or vigorously active reduced their risk of heart attack and stroke by 11%.
The lead researcher Kyuwoong Kim says: “The most important message from this research is that older adults should increase or maintain their exercise frequency to prevent cardiovascular disease.”
A new study, carried out by researchers from Hôpital de la Pitié-Salpêtrière in Paris, France, finds that too much exercising may affect the brain, in particular, reduce the capacity to make decisions.
For the study, the scientists recruited 37 competitive male endurance athletes whose average age was 35 years. For the study purposes, one group of participants continued their regular regimen, and another group increased their training by 40% per session over a period of 3 weeks.
After 3 weeks, the researchers tested the economic choices of all athletes found that overloaded athletes were more likely to make their choices more impulsively.
The corresponding author Mathias Pessiglione comments: “This brain region, therefore, appeared as the weak spot of the brain network responsible for cognitive control. You need to control the automatic process that makes you stop when muscles or joint hurts.”
A new Finnish study, published in the journal Frontiers in Microbiology, finds that endurance exercises may change the composition of gut microbiota.
The researchers developed a 6-week program of bicycle training and enrolled 17 overweight women for this program. All women led a sedentary lifestyle before joining the study.
At the end of the program, the scientists noticed that the number of proteobacteria, gut bacteria that cause inflammation, decreased and the number of beneficial bacteria Akkermansia, linked to better metabolism, increased.
The corresponding author of the study Satu Pekkala, an Academy of Finland research fellow affiliated with the Faculty of Sport and Health Sciences of the University of Jyväskylä, explains: “These changes are beneficial for cardiometabolic health, because VLDL transports lipids from the liver to peripheral tissues, converts into ‘bad’ LDL [low-density lipoprotein] cholesterol in the circulation, and thus has detrimental cardiovascular effects.”
A new German study, published in the journal Cell Reports, suggests that parents may boost the intelligence of their offspring by exercising.
The research, using a mice model, showed that active mice are more likely to have offspring with the higher ability to learn compared to mice whose movement was restricted. German researchers identified that “microRNA” molecules which were known to promote this neuron connectivity in the brain, as well as in the sperm, in response to exercise.
Study author Professor André Fischer from the German Center for Neurodegenerative Disease says: “Presumably, [miRNA212 and miRNA132] modify brain development in a very subtle manner improving the connection of neurons. This results in a cognitive advantage for the offspring.”
We all know how to burn calories by working out. But what about burning calories after you’ve finished exercising? You can boost post-exercise afterburn using just one of these seven weight-loss strategies, approved by health experts:
Prioritize bigger compound exercises like chest presses over isolation moves like biceps curls.
Lift heavy weights as it spikes your afterburn.
Do not skip high-intensity interval training. HIIT workouts offer an effective method to keep your body burning calories after you have cooled down.
Take a metabolic resistant training. It challenges your muscle and anaerobic system.
Monitor your heart rate during the workout.
Increase the intensity and efficiency of a strength-training routine by performing two exercises back-to-back.
Use heavier weights during the final two or three repetitions of the exercise.
