The Claim
Twelve weeks of high- or moderate-intensity interval training in obese adolescent females reduces blood leptin concentration by approximately 22–23%, and this reduction is strongly associated with decreases in body fat percentage and, in the moderate-intensity group, with improvements in aerobic capacity.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
After twelve weeks of high- or moderate-intensity interval training, obese adolescent females experience a 22–23% decrease in blood leptin levels, which corresponds to a reduction in body fat and, in the moderate-intensity group, an increase in aerobic capacity.
See the scientific wording
Twelve weeks of high- or moderate-intensity interval training in obese adolescent females likely reduces blood leptin concentration by approximately 22–23%, which is strongly associated with reductions in body fat percentage and, in the moderate-intensity group, with improvements in aerobic capacity.
When obese adolescent females do high- or moderate-intensity interval training, their bodies burn more fat, causing fat cells to shrink. Smaller fat cells produce less of the hormone leptin, so less leptin enters the bloodstream. The amount of leptin that drops matches exactly how much fat is lost.
What the research says
1 studyThe study found that obese teenage girls who did either intense or moderate interval workouts for 12 weeks had a big drop in a fat-related hormone called leptin, and this drop matched how much fat they lost — and in the moderate group, how much better their fitness got.
