The Claim
Three weeks of sprint interval training (SIT) is associated with improved recovery from low-frequency fatigue (LFF) in healthy older men aged 63–72, as demonstrated by a statistically significant main session effect (P=0.0029), indicating enhanced neuromuscular resilience following repeated high-intensity exercise sessions.
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.
After just three weeks of short, intense bike or sprint workouts, older men between 63 and 72 got better at bouncing back from muscle tiredness caused by repeated hard exercise — their muscles recovered faster and felt stronger afterward.

What the research says
1 studyThe study gave older men three weeks of short, intense bike sprints and found they bounced back faster from muscle fatigue afterward, which is exactly what the claim says.
