A Manchester Metropolitan University study has found that taking carbohydrate and protein supplements just before and just after low-resistance exercise could boost muscle performance and slow muscle wastage in people over retirement age.
Moreover, this combination appears to deliver greater fitness benefits than undertaking heavy-resistance training with or without changing one’s nutritional habits.
This was the first-ever study of the combination of structured exercise and nutritional supplements to focus wholly on older people. Undertaken as part of the SPARC (Strategic Promotion of Ageing Research Capacity) initiative, the findings will be discussed at this year’s BA Festival of Science in Liverpool on Thursday 11th September. SPARC is supported by the Engineering and Physical Sciences Research Council (EPSRC) and the Biotechnology and Biological Sciences Research Council (BBSRC).
This groundbreaking study involved a carefully selected sample of around 60 healthy, independent-living adults aged 65 and over.
The volunteers were randomly divided into groups who underwent different 12 week programmes of physical exercise and nutritional supplementation. Everyone was then re-assessed at the end of the programme.
Some groups undertook low-resistance exercise once a week; others undertook high-resistance exercise twice a week. Within each group, some of the volunteers took protein and carbohydrate supplements while others did not.
When all the participants were re-assessed at the end of the 12 week programme, it was observed that muscle size and strength had increased in all groups.
However, the results suggested that older people would derive the most benefits if they took appropriate supplements coupled with low-intensity exercise.
“Maintaining muscle performance and arresting muscle wastage can offer older people real improvements in their quality of life,” says Dr Gladys Pearson, who led the research. “Though we still need to assess precisely what level of exercise gives the best results, we believe we’ve shown that regular low-resistance exercise complemented by the right nutritional supplements could boost the well-being of the UK’s ageing population.”
Dr Pearson and her team now aim to look at the effectiveness of novel combinations of strength training and nutritional supplementation as a way of speeding recovery and improving mobility for old and young orthopaedic surgery patients.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
