NEW YORK: Are you struggling to deal with jet lag? Exercise can change the body clock and help you adjust to offbeat schedules, suggests new research.

The study, conducted by Arizona State University, showed that exercise can alter the human biological clock with the direction and amount of this effect, depending on the time of day or night at which people are exercising.

Exercises at 7am or between 1pm and 4pm advanced the biological clock to an earlier time and exercised from 7pm to 10pm. delayed the biological clock at a later time.

Exercising between 1h and 4h and 10h, however, has little effect on the biological clock and the effects of phase shift exercise do not differ depending on age or sex, said the researchers.

"It is known that exercise alters the body clock.We could clearly show in this study that exercise delays and advances the time," said lead author, Shawn Youngstedt, from the university.

"This is the first study to compare the effects of exercise on the body clock and could open 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 that exercise could counter the effects of jet lag, shift work and other disturbances to the body's internal clock (for example, deployments military) helping individuals adapt to changing schedules.

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

The basic frequency of the biological clock of each participant was determined from urine samples taken every 90 minutes to measure the time of the evening rise of melatonin and the melatonin spike several hours later.
