The Claim
Sprint interval training (SIT) induces divergent adaptations in aerobic capacity (VO2max) between young and older men, resulting in a statistically significant increase from 40.8 to 43.0 mL/kg/min in young men but no significant change in older men, indicating age-related differences in cardiovascular responsiveness to short-duration, high-intensity exercise.
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.
When young and older men do short, super-intense bike or sprint workouts, the young guys get better at using oxygen during exercise, but the older guys don’t — their bodies just don’t respond the same way.

What the research says
1 studyThe study found that young men got better at using oxygen after short, intense bike sprints, but older men didn’t — just like the claim said.
