The Claim
Twelve weeks of high-intensity interval training in obese adolescent females reduces ratings of perceived exertion (RPE) after maximal exercise by 29% compared to a 14% reduction with moderate-intensity training.
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.
Obese adolescent females who do 12 weeks of high-intensity interval training experience a 29% lower rating of perceived exertion after maximal exercise compared to those who do moderate-intensity training, which results in a 14% reduction.
See the scientific wording
Twelve weeks of high-intensity interval training in obese adolescent females likely reduces ratings of perceived exertion (RPE) after maximal exercise by 29% compared to 14% with moderate-intensity training, suggesting improved exercise tolerance and reduced subjective effort during physical activity.
After training, the body becomes more efficient at using oxygen during exercise, and the heart and lungs work less hard to deliver oxygen to muscles. At the same time, the body weighs less, so moving requires less effort. This combination makes intense exercise feel easier, even when pushing to maximum effort.
What the research says
1 studyAfter 12 weeks of workouts, obese teenage girls who did short, intense bursts of exercise felt less tired during hard activity than those who did slower, moderate exercise—even though both groups got fitter. The intense group felt 29% less exertion, while the moderate group felt 14% less.
