Exercise during pregnancy

Doctors should recommend low to moderate levels of exercise to pregnant women because it can strengthen and improve overall musculoskeletal and physiologic health as well as pregnancy related symptoms, according to a review article.

Published in ‘Journal of the American Academy of Orthopaedic Surgeons’, the report suggests that exercise — such as aerobics, impact and nonimpact activities, resistance training, and swimming — eases back and other musculoskeletal pain, lowers maternal blood pressure, reduces swelling, and improves post-partum mood.

According to author Capt Marlene DeMaio, Naval Medical Centre, Virginia, the study indicates that the pregnant woman’s body can compensate for the changes with no harm to the foetus during low to moderate intensity exercise.

“It is important to remember that pregnancy is a temporary condition, not a disease, and that the musculoskeletal and physiologic changes that happen are normal in the majority of patients,” she said.

Marlene also believes that starting an exercise programme when pregnant, is a perfect way to begin — and stick with — a fitness programme.

PE related injuries are on the rise

There has been a drastic increase in the number of physical education-related injuries among school students over a decade, according to a study.

The study reveals that there has been 150 per cent increase from 1997-2007. Physical education (PE) in schools is one of the main tools used to increase physical activity and to prevent childhood obesity, but parents and school administrators should remain vigilant for injuries.

The findings indicated that 23 per cent of the PE-related injuries were lower-extremity sprains and strains, while 14 per cent suffered upper extremity sprains and strains and fractures.

The mystery behind diseases

An Indian-origin professor at the UC San Diego Jacobs School of Engineering may be very close to unravelling the mystery behind the origin of many diseases, such as cancer.
Nanoengineering professor Gaurav Arya has developed engineering tools and computer simulations that provide new insights into biology.

Arya says that this work has been carried out in collaboration with researchers from Penn State University, University of Massachusetts, and New York University.

The report states that the researchers have used innovative approaches to deduce the internal structure of chromatin, a key player in DNA regulation.

Chromatin is a complex combination of DNA and proteins that makes up chromosomes, but its internal structure is not known — a mystery that has baffled scientists for more than three decades.

Lack of sunlight causes brain drain

Depressed people are less able to think clearly when there’s a short-term lack of sunlight, a new study has found.

Researchers used weather data from NASA satellites to measure sunlight exposure across the United States and linked this information to the prevalence of cognitive impairment in depressed people.

The team of US researchers used cross-sectional data from 14,474 people in the NIH-NINDS-funded REGARDS study, a longitudinal study investigating stroke incidence and risk factors, to study associations between depression, cognitive function and sunlight.
