The Claim
Six weeks of sprint interval training in healthy male adolescents leads to a reduction in serum levels of five specific polyunsaturated free fatty acids (FFA 16:2, 18:3, 18:4, 22:5, and 22:6), indicating a selective effect on circulating free fatty acid metabolism that may influence lipid utilization and metabolic health.
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.
Doing short, intense sprints for six weeks might lower certain types of fats in the blood of healthy teenage boys, which could mean their bodies are using fat differently in a way that's good for their health.
