The changes are very quickly. I have come across numerous studies showing
1) sprints are 10-15 times more efficent than jogging, for fat loss
2) There is a large increase Post Excersice Oxygen Consumption, which eats up calories like nothing else for hours after.
3) While initally increasing Cortisol during/slightly after, it lowers baseline cortisol.
4) Increase glycogen/ insulin sensitivity, probably through lowering cortisol.
5) Sprints also activate the Glutes(since walking/jogging doesn't), and put considerable stress on the Core muscles to keep the body balanced with the rotation of the shoulders. So localized fat loss in the core, while also building the glutes.
Essentially it's the hardest exercise to do, while having the highest rewards.
If u can motivate yourself you will see fat distribution in your face/neck within the first week, assuming your relatively young/male, but I am sure the benefits are universal regardless of age/gender.
. It's essential to have large glucose loads after(potatos), as well as gelatin Fructose as well., Just some fruit/milk after will not be enough and you may feel like you got hit by a truck the next day. plenty of rest between 2-3 days.
A few sprints depletes glycogen quicker than 45min jogs.
Thank you for all these details. One more thing - how long do you wait to recover in between sprints?
