The chair test says more than the scales — and muscle comes back into old age, but only with resistance and protein together.
Also known as: sarcopenia · age-related muscle loss

From about the age of fifty the body loses some muscle mass each year, and strength falls even faster than mass. Precisely for that reason sarcopenia is not measured by weight but by performance: how long it takes to stand up from a chair five times without hands, how firm the handgrip is, how fast a short distance is walked. Needing more than about twelve seconds for the five stands is a clear sign — and it can be checked at home. The loss does not run evenly but in steps: every week in bed, every bout of flu, every operation costs a great deal at once, and without deliberate rebuilding it does not come back by itself. That is why a stay in hospital changes some people for good. The good news is unusually clear: muscle can be rebuilt into very old age, even at ninety. Two things are needed together — resistance, that is training against a pull or a weight, and enough protein spread across the day. One alone is not enough. Caution is due with weight-loss diets in later life, because without training it is mainly muscle that goes.
Sit on an ordinary chair, cross the arms over the chest, stand up and sit down five times, take the time. Clearly over twelve seconds is a sign. The test costs nothing and can be repeated every few months.
This is the only measure that truly turns the course around. A resistance band, two water bottles or one’s own body weight are enough to start; what counts is that it grows heavier over time, not merely longer.
Muscle only responds above a certain amount per meal. Eating everything in the evening works less well than three medium portions — quark, eggs, fish, meat, pulses, dairy.
A shortage weakens muscle and balance at once. It is common in winter, simple to measure and simple to correct.
In illness and after operations every movement counts: circling the feet, tensing the legs, sitting on the edge of the bed several times a day. That slows exactly the step that otherwise stays.
Without strength training, weight lost in later life consists largely of muscle. Anyone who wants to lose weight does better slowly, with plenty of protein and training alongside.
There is no drug that builds muscle. What builds muscle is resistance: strength training two to three times a week shows measurable gain after eight to twelve weeks even in people over eighty. Protein alone is not enough but is the condition — about 1.0 to 1.2 grams per kilo of body weight daily, spread across meals. Vitamin D and creatine have been studied as additions; they strengthen the training, they do not replace it.
From about thirty, three to eight per cent of muscle mass is lost per decade, considerably faster from sixty. Ten days of bed rest cost about a kilogram of muscle in people over sixty — and it does not come back by itself. Grip strength is the simplest measure: under 27 kilograms in men and 16 in women counts as abnormal. Strength training twice a week shows measurable gain after eight to twelve weeks even in people over eighty.
Against age-related muscle loss, strength training is the single strongest lever — two to three times a week, with slowly rising resistance. Protein alone builds no muscle; it needs the stimulus. You start with your own body weight; no equipment is needed to begin.
Having to push off to get up from a chair already means a clear loss of leg strength. It is the earliest everyday sign.
When a green light is no longer enough or others pull ahead, it has become measurable. Walking speed says surprisingly much about the years ahead.
A few days of bed rest cost a lot of leg muscle. Without deliberate rebuilding that step remains — so movement belongs already in the time in bed.
If the trousers grow loose at the thigh while the weight stays, muscle has been replaced by fat. The scales do not reveal that.
Stumbling and falls are among the most serious consequences. They are often the first occasion on which anyone looks — earlier would be better.
A shortage weakens the muscles and raises the risk of falling. It is one of the few gaps that can be closed simply and cheaply.
An often overlooked side effect: creatinine comes from muscle. With little muscle mass the calculated kidney function looks better than it is — which can distort drug dosing.
Together with a weight trend, a hint that it is not only the training that is missing but the intake as well.
Both an under- and an overactive thyroid weaken the muscles. One value that either rules out or finds a treatable cause.
Strength training is the only measure that really brings back muscle mass in later life.
