‘Best to gym in the day’

Weekend Argus (Saturday Edition) - - FRONT PAGE -

LON­DON: Work­ers with lit­tle spare time can of­ten end up in the gym at night, pound­ing the tread­mill.

But re­search sug­gests this is the worst time to ex­er­cise, be­cause our mus­cles func­tion bet­ter dur­ing day­light hours.

The study from Northwestern Uni­ver­sity in the US found mus­cle cells, like the body clock, re­spond dif­fer­ently dur­ing our 24-hour day.

The cells con­trol the process by which the body makes en­ergy when we are exercising hard – switch­ing from oxy­gen to su­gar for en­ergy.

How­ever, in a study in­volv­ing mice, this process was found to work bet­ter dur­ing nor­mal wak­ing hours. It means hu­mans, who share the same genes, may also find their mus­cles re­spond bet­ter to ex­er­cise dur­ing the day.

Re­searchers be­lieve this is be­cause pro­teins are primed to re­spond bet­ter dur­ing a time of day when de­mand for stren­u­ous ac­tiv­ity is usu­ally great­est. – Daily Mail
