A SHORT stroll may seem like awalk in the parkto some, but exhausting for others.

If you’re over the age of 60, feeling tired after light exercise or even socialising could signal an early grave.

Scientists studied more than 2,900 adults over 60 and found a key indicator of an early death

Scientists from the University of Pittsburgh say that if you feel particularly tired after a walk or light housework, you may be at an increased risk of dying over the next three years.

Más que 2,900 older adults over the age of 60 participated in a studythe first to make such conclusions.

The participants rated how tired they typically felt following various activities on a scale of one to five.

Activities also included gardening, watching TV, socialising with friends and weight-based Probé la 'regla de los tres minutos' para las tareas del hogar.

Each adult was given a “fatigability” score between 0 (low) y 50 (elevado) to indicate how fatigued they felt after exercise.

According to findings published in the Journal of Gerontology, those with the highest scores were more likely to die in the follow-up period.

Those with a score of more than 25 were more than twice as likely to pass away over the next 2.7 years in comparison to others who scored below 25 puntos.

The researchers took account of other factors that may have contributed to their death, such as age and gender.

The study suggests that feeling tired after exercise is not directly linked to death, but instead a marker of other underlying health problems.

Lead author Dr Nancy Glynn said: “This is the time of year when people make—and break—New Year’s resolutions to get more physical activity.

“I hope our findings provide some encouragement to stick with exercise goals.

“Previous research indicates that getting more physical activity can reduce a person’s fatigability.

“Our study is the first to link more severe physical fatigability to an earlier death. Conversely, lower scores indicate greater energy and more longevity.”

Dr Glynn said one of the best ways to increase exercise is to set small goals, such as a regular walk.

It comes as another study shines light on the power of a short burst of exercise every day in preventing deaths.

Researchers at the National Cancer Institute and the CDC found that if people walked briskly for an extra 10 minutes a day, casi 111,200 deaths could be prevented in America each year.

This doubled to 209,500 por 20 minutos, y 272,300 por 30 minutos – 17 per cent of the annual death toll.

Their findings, published in JAMA Internal Medicine, were based on the mortality data of 4,800 people who wore a fitness tracker in the early 2000s.

How much exercise is recommended by the NHS?

There are guidelines issued by the NHS and the Government regarding how much exercise people should do each day.

People should be active daily, and avoid sitting for long periods of time.

Covering each age group, from young to old, they recommend an adult – those aged 19 para 64 – should aim for 150 minutes of “moderate intensity activity” a week.

This works out to 21 minutes a day, o 30 minutes five days a week.

As well as this, people should also aim to do a physical activity twice a week to keep the muscles in good condition.

los NHS says aerobic and strength exercises should be done bi-weekly.

They recommend cycling, a brisk walk, tennis or running.

And for strengthening they advise completing workouts twice a week which focus on the main muscle groups, including the legs, espalda, pecho, brazos, abdomen and hips.

The NHS says: “A good rule is that 1 minute of vigorous activity provides the same health benefits as 2 minutes of moderate activity.

“All adults should also break up long periods of sitting with light activity.”
