Want faster fat loss? Take a leaf out of Usain Bolt’s sport, and get your sprint on…
In studies conducted by the Zinman College of Physical Education, sprinting has been shown to produce a number of hormonal changes in the body that both aid muscle repair and ignite the metabolism, helping to burn fat.
In the study, subjects ran four sets of 250m sprints at 80% of maximum effort, with a three-minute rest in between each sprint.
Blood samples were taken before the exercise, immediately after the sprint and one hour after the run had finished to check levels of testosterone, cortisol and other key hormones.
The levels of testosterone were elevated for an hour after the exercise had finished, which in turn suppressed levels of the fat-storing hormone cortisol. In summary, short sprints created just the right level of hormone production, and the right types of hormones, to promote faster fat loss.
So the message is simple – make like Usain Bolt and you could see faster fat loss thanks to short sprints.
