Ladies, stop blaming genes for your larger waistline as you can overcome the genetic predisposition to obesity through exercise, a new study suggests.

The study found that physical activity reduces the influence of genetic predisposition to obesity, and this effect is more significant in the oldest age group — women aged 70 years and older.

These findings additionally support guidelines for promoting and maintaining healthy behaviours, especially in older adults, to maximize quality and longevity of life, the researcher said.

The researchers found that greater symptoms of depression were linked to worse episodic memory -- a person's ability to remember specific experiences and events.

“We are born with our genes, but this study suggests that we can improve our lives and health with exercise, regardless of genetics,” said Joann Pinkerton, executive director at the North American Menopause Society in the US.

“As women age, exercise has been shown to improve muscle mass, balance and bone strength. It also invigorates brain cells, is associated with less arthritic pain, and improves mood, concentration, and cognition”, Pinkerton added.

The researchers also mentioned that regardless of age, genes, and amount of abdominal fat or body mass index (BMI), regular exercise can improve health.

For the study, published in the journal Menopause, the researchers analysed more than 8,200 women.

The previous studies have suggested that the genetic influence on BMI increases from childhood to early adulthood, the researcher said. (IANS)

Exercise May Help You Counter Effects of Jet Lag

Finding it hard to cope with jet lag, shift-based work? Doing some excercise can shift the human body clock and help you adjust to the shifted schedules, suggests new research.

The study, from the Arizona State University, showed that exercise can shift the human body clock with the direction and amount of this effect depending on the time of day or night in which people exercise.

Exercising at 7 a.m. or between 1 and 4 p.m. advanced the body clock to an earlier time, and exercising between 7 and 10 p.m. delayed the body clock to a later time.

Exercising between 1 and 4 a.m. and at 10 a.m., however, had little effect on the body clock, and the phase-shifting effects of exercise did not differ based on age or gender, the researchers explained.

“Exercise has been known to cause changes to our body clock. We were able to clearly show in this study when exercise delays the body clock and when it advances it,” said lead author Shawn Youngstedt, from the varsity.

“This is the first study to compare exercise’s effects on the body clock, and could open up the possibility of using exercise to help counter the negative effects of jet lag and shift work.”

The findings, published in The Journal of Physiology, suggest exercise could counter the effects of jet lag, shift work, and other disruptions to the body’s internal clock (e.g., military deployments) helping individuals adjust to shifted schedules.

For the study, the team examined body clocks following exercise in 101 participants for up to five-and-a-half days.

The baseline timing of each participant’s body clock was determined from urine samples collected every 90 minutes to measure the time of the evening rise in melatonin and the peak of melatonin several hours later. (IANS)
