The Claim
In healthy male adolescents aged 13 years, six weeks of either sprint interval training or moderate-intensity continuous training leads to an improvement in peak oxygen uptake (VO2peak) of approximately 8.5 mL/kg/min, with no significant difference in effectiveness between the two exercise modalities, indicating equivalent benefits for aerobic capacity enhancement.
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.
Both short, intense sprints and steady, moderate workouts boost teenage boys' stamina just as much after six weeks — either way, their bodies get better at using oxygen.
See the scientific wording
Six weeks of either sprint interval training or moderate-intensity continuous training improves peak oxygen uptake (VO2peak) by approximately 8.5 mL/kg/min in healthy male adolescents aged 13 years, with no significant difference between the two exercise modalities, indicating that both are equally effective for enhancing aerobic capacity in this population.
What the research says
1 studyThe study found that both short, intense workouts and longer, moderate ones improved teens' aerobic fitness by about the same amount after six weeks, just like the claim says.
