The Claim
Master athletes exhibit a greater peripheral vasodilatory response during exercise compared to sedentary older adults, and this difference is associated with preserved vascular function in aging.
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.
Older athletes who have trained endurance throughout their lives show stronger blood vessel widening during exercise than older adults who are inactive, indicating their blood vessels maintain better function with age.
See the scientific wording
Master athletes exhibit greater peripheral vasodilatory response during exercise than sedentary older adults, suggesting that lifelong endurance training is associated with preserved vascular function in aging.
Lifelong exercise keeps blood vessels flexible and responsive by maintaining high levels of a signaling molecule called nitric oxide. When muscles work harder during exercise, this molecule tells the small blood vessels to widen, allowing more blood and oxygen to flow to the muscles. This ability does not weaken with age in people who train regularly, unlike in those who are inactive.
What the research says
1 studyStudy: A hemodynamic comparison of young and older endurance athletes during exercise.
Older athletes who train regularly have blood vessels that open wider during exercise than older people who don’t exercise, helping more blood and oxygen reach their muscles. This shows staying active helps keep blood vessels healthy as we age.
