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)

Heart patients who exercise regularly and have better fitness are likely to have less cognitive impairment, says a study. Fitter patients have better memory, it adds.

The study analysed data from over 600 male patients, aged 67-71 years, with heart failure from six countries. During the research, the “Montreal Cognitive Assessment” test was used to measure cognitive function and exercise capacity was measured with a six-minute walk test.

The results showed the younger and better educated heart failure patients with better fitness were significantly less likely to have cognitive impairment.

Two-thirds of the patients with heart failure had cognitive problems, showed the study, presented at the EuroHeartCare 2019, a scientific congress of the European Society of Cardiology (ESC), held in Milan, Italy, from May 2 to May 4.

According to the study, cognitive dysfunction is a common problem in the patients with heart failure with 67 per cent reporting at least mild impairment.
