Keeping active pays off even in your 70s and 80s

28.05.2014

Older people who undertake at least 25 minutes of moderate or vigorous exercise everyday need fewer prescriptions and are less likely to be admitted to hospital in an emergency, new research has revealed.

The findings, published in the journal PLOS ONE, reinforce the need for exercise programmes to help older people stay active. It could also reduce reliance on NHS services and potentially lead to cost savings.

In the first study of its kind looking at this age group, researchers from the University of Bristol looked at data from 213 people whose average age was 78.

Those who carried out less than 25 minutes of moderate to vigorous physical activity per day – such as walking quickly, cycling or swimming - received 50 per cent more prescriptions over the following four to five years than those who were more active.

Such physical activity leads to a higher metabolism and better circulation, reducing the risk of conditions and diseases common in older age such as high blood pressure, type 2 diabetes, coronary heart disease and strokes.

The study also found that being physically active reduced the risk of unplanned hospital admissions. Those who were in the most active third of the sample were on average achieving 39 minutes of moderate-to-vigorous activity and were at half the risk of emergency hospital admissions than those in the low active group.

These results remained significant even when other factors affecting health were taken into account, such as socio-economic status, education, weight, existing disease and level of physical function.

Researchers measured physical activity using accelerometers - small gadgets that monitor all movement throughout the day - alongside elements of physical function including balance, leg strength and walking gait.

Medical records were then examined to investigate health service usage over the next four years. This captured visits to primary care, referral for secondary services, unplanned admissions to hospital and the number of prescriptions needed.

Being active was not associated with the frequency of visits to the doctor, or referral for other hospital services.

The research was co-authored by Dr Bethany Simmonds and Professor Ken Fox, from Bristol University's Centre for Exercise, Nutrition and Health Sciences.

Dr Simmonds, now based in the School of Clinical Sciences, said: "We know that leading a physically active life has health benefits for all ages, but this study suggests there may also be economic benefits by reducing reliance on medication and preventing costly emergency hospital admissions. Our findings further support the need for greater availability of community-based programs to increase physical activity and prevent loss of lower limb function."

The results support the recent recommendations from NICE that all GPs should encourage physical activity in their older patients.

Exercise should be targeted and tailored to those in their 70s and 80s, aiming to increase muscle strength, balance, coordination and aerobic fitness to maintain mobility and prevent falls and further disease.

Professor Ken Fox added: "Until now, very little has been known about the value of physical activity in later life, particularly when people are in their 70s and 80s. This research underlines that keeping older people active brings a whole range of health benefits, as well as reducing reliance on the NHS and potentially leading to major cost savings."

The study was part of the OPAL-PLUS project, supported by The Dunhill Medical Trust [grant number: R200/0511] with additional support from the Avon Primary Care Research Collaborative and the South West General Practitioners Trust. Researchers at the University of Bristol worked with colleagues at the University of Bath and UWE Bristol.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
