Could eccentric cycling be a smarter workout for obese teens?

NCT ID NCT02925572

First seen Aug 07, 2026 · Last updated Aug 07, 2026

Summary

This trial tests whether a 12-week program of eccentric cycling—where muscles lengthen under load, like pedaling against resistance—can reduce body fat in overweight and obese teenagers more effectively than traditional concentric cycling. The study compares both types of exercise at the same oxygen consumption level to see if the higher mechanical load of eccentric work leads to greater fat loss and improvements in metabolic health. Participants are teens aged 12 to 17 with a BMI above the 90th percentile, and the trial measures changes in total body fat, fitness, strength, and blood markers.

What this could lead to
If eccentric cycling proves more effective, it could offer a more efficient exercise strategy to reduce fat mass in obese teenagers, potentially improving metabolic health.
What could go wrong
This is a small early-stage trial, so results may not be conclusive or widely applicable. Eccentric exercise can cause muscle soreness, and adherence may vary.
