Fitness & sleep
Muscle fiber, tendons, chronotype, longevity: the training and recovery side of your genome.
Your body clock keeps time even when you do not
Sleeping in on Saturday flies your internal clock a few time zones west and back again. What social jetlag is, why the wake time is the anchor, and how late coffee and a nightcap fit in.
The soreness two days later is not lactic acid
Lactate clears within about an hour. The ache peaks at 24 to 72 hours. The 1983 study that broke the link, what actually causes it, and why stretching first does not prevent it.
The genes your tendons are made of
COL5A1 and TNC variants shift how resilient connective tissue tends to be. What a meta-analysis actually shows about soft-tissue injuries, and what a runner should do with a strain lean.
Night owl or early bird: what your genes set, and what they don't
Chronotype is real, partly heritable, and studied in almost 700,000 people. Here is what the clock genes actually move, in minutes, not destiny.
ACTN3, the so-called sprinter gene, and what it can't tell you
About one in five Europeans has no alpha-actinin-3 protein at all and most never notice. What the famous power gene really predicts, and what it doesn't.
FOXO3 and the genetics of living to 95
One maintenance gene keeps showing up in centenarian studies across continents. What the longevity variant actually buys you, in honest odds.
