Fitness can pay off in the longest run
A TEAM of scientists is exploring the molecular basis of fitness and aiming to develop a simple blood test to determine a person’s level of health and wellbeing, a report says.
Stanford University School of Medicine scientists wanted more details to assess aerobic fitness. They sought more than the assessment from the peak VO2 test on a treadmill that measures the oxygen used.
“Everybody knows exercise is good for you, but we really don’t know what drives that at a molecular level,” said Professor Michael Snyder.
“Our goal was to conduct a highly comprehensive analysis of what’s happening in the body just after exercising.”
The 36 participants and hundreds of thousands of molecular measurements let researchers track markers for metabolism, immunity, oxidative stress and cardiovascular function.
The tests let researchers examine chemical variations in the body while the participants did intense exercise.
For those who performed better on the treadmill VO2 test, scientists found a strong and interesting correlation but have not yet unravelled the reason for it. The participants who were most physically fit had similar molecular signatures in their resting blood samples before exercise.
Aerobic fitness can be one of the best measures of longevity.
