Cells remember every workout
Your cells keep exercise records that last beyond breaks from training.
In brief
Your cells keep exercise records that last beyond breaks from training. Muscle and liver cells store exercise memories that improve endurance and blood sugar even after stopping workouts. Originally reported by The Conversation.
Cells store exercise memories
Muscle and liver cells keep records of every workout you've ever done.
Old belief about exercise fades
For most of the past century, exercise benefits were thought to fade when you stopped training.
Consistency is hard to maintain
Three in four American adults can't consistently exercise due to injuries, illness or work.
Exercise memory in mice
Researchers used an ON-OFF-ON training protocol in mice to study exercise memory.
Muscle grows faster with memory
Retrained mice developed bigger muscles and stronger fibers than those with no training history.
Muscle energy efficiency improves
Muscle cells better match energy production to demand after retraining.
Liver stores exercise memory
Liver cells release enzymes to feed muscle more efficiently after retraining.
Exercise memory lasts generations
Parental exercise can protect offspring from poor blood sugar and weight gain for a year.
What it means
Muscle and liver cells store exercise memories that improve endurance and blood sugar even after stopping workouts.
