Hi everybody. I`m planning to put sprints back into my routine, because i`m not pleased with my progress. My goal is fat loss/general fitness. So my question is: Are longer sprints, like 200 - 400 m generally better for fat loss than short distances? If i sprint 200m uphill, jog back and repeat until i cant do no more, lets say 5-7 times, is it more effective than sprinting 50 - 100m uphill jog back and repeat until i can do no more, like 10 - 15 times? When comparing hiit to lsd it is often talked about the body`s "hormonal response"? Is it the same for both ways (long sprints/short sprints) if you really go until you cant anymore or has one an advantage above the other? Thank you!
