Regular Exercise to Help Prevent Development of Physical Signs of Alzheimer’s

For the results, the research team conducted three studies--in the first study, the researchers examined 317 participants enrolled in the Wisconsin Registry for Alzheimer's Prevention

Regular exercise is not only good for memory as people age, but it also appears to help prevent the development of physical signs of Alzheimer’s, in those who are at risk for the disease, says a study.

“Our research shows that in a late-middle-age population at risk for Alzheimer’s disease, physically active individuals experience fewer age-related alterations in biomarkers associated with the disease, as well as memory and cognitive functioning,” said Ozioma Okonkwo, Assistant Professor at the University of Wisconsin.

For the results, the research team conducted three studies–in the first study, the researchers examined 317 participants enrolled in the Wisconsin Registry for Alzheimer’s Prevention, an ongoing observational study of more than 1,500 people with a history of parents with probable Alzheimer’s dementia.

In the second study, researchers studied 95 people, also from the registry, who were given scores called polygenic risk scores, based on whether they possessed certain genes associated with Alzheimer’s.

Similarly, the third study examined MRIs from 107 individuals from the registry who were asked to run on a treadmill to determine their oxygen uptake efficiency slope, a measure of aerobic fitness.

Participation in the registry included an initial assessment of biological, health and lifestyle factors associated with the disease and follow-up assessments every two to four years.

All participants completed a questionnaire about their physical activity and underwent neuropsychological testing and brain scans to measure several biomarkers associated with Alzheimer’s disease.

The researchers compared data from individuals younger than 60 years with older adults and found a decrease in cognitive abilities as well as an increase in biomarkers associated with the disease in older individuals.

However, the effects were significantly weaker in older adults who reported engaging in the equivalent of at least 30 minutes of moderate exercise five days a week.

“The most interesting part of our research is that we now show evidence that lifestyle habits – in this case regular, moderate exercise – can modify the effect of what is commonly considered a non-modifiable risk factor for Alzheimer’s, in this case, aging,” Okonkwo said.

“Overall, these studies suggest that the negative effect of aging and genetic risk on Alzheimer’s’ disease biomarkers and cognition can be lessened in physically active, older adults at risk for the disease compared with their less active peers.” (IANS)

Poor posture can not only make you look bad but can also have adverse effects on your overall health and lifestyle.

“Maintaining poor postures for long periods of time affects the natural alignment of the body and lowers energy levels. In addition to soreness and pain in the body, poor posture can also lead to physical and mental stress.

“Postures defects can negatively influence lung function and lead to shortness of breath. Long term effects of bad posture could even impact blood circulation, digestive pattern as well as the nervous system. People who tend to slouch have also often reported having headaches,” Dr Sumalatha KB, Consultant, Physical Medicine and Rehabilitation, Aster CMI Hospital told IANSlife.

The expert shares these top tips to maintain correct postures:

1. Become more mindful of your posture throughout the day, even when you are absorbed in any external activities. Exercises focusing on the body core help immensely in retraining the body to hold itself the right way, while also increasing self-awareness of the body.

2. Exercise in the correct form, and invest in rest and recovery after a workout. Engage in muscle-strengthening exercises.

3. It is advised to switch sitting positions, take brief walks and breaks from the computer system on your workdays. Do not stay in the sitting position for too long. Ensure you stand/walk often and stand straight while you do it. Doing this can help you prevent pain, injuries and other health problems. (IANS)
