Exercise is better in the morning if you have a stressful job, as mental fatigue can affect physical performance, says a new study.esearchers at Bangor University found that people who are mentally fatigued and exercise reach the point of physical exhaustion sooner than they do if they are mentally rested before exercising.
Also, they found that even though being exhausted after work doesn't actually affect the muscles, it does make it harder for people to exercise so vigorously.
AdvertisementThe researchers reckon that it makes people 'perceive' that exercise is more exhausting and could lead to treatment for chronic fatigue syndrome.
"People with chronic fatigue report that they lack energy and experience 'brain fog', just like the mentally fatigued participants in this study," the Telegraph quoted Dr Samuele Marcora, as saying.
"In addition, as in this study, people with chronic fatigue perceive exercise to be more difficult despite physiological responses considered normal during exercise," Marcora added.
The study, therefore, suggests that athletes and stressed workers would be better to train when their minds are fresh although researchers said any exercise was still beneficial.
"People who exercise after work should continue doing so, even if mentally fatigued, " Marcora said.
"Most people work out at a moderate intensity, which still gives plenty of physiological and psychological benefit, including relief from stress and improved mental performance," the expert added.
In the study, 16 volunteers were asked to exercise on a bike, half the time when their mind was fresh and half the time after 90 minutes of mentally fatiguing work.
The researchers found that participants stopped exercising on average 15 per cent earlier when they were mentally fatigued.
