Maximising energy for sporting performance

07.02.2007
Athletes in training for the London Marathon could improve their performance significantly by giving more thought to what they eat and drink, according to researchers at the University of Hertfordshire.

Dr Peter Jones, a senior lecturer at the University’s School of Life Sciences, was involved with two research projects which have thrown new light on the best foods and drinks to ingest prior to sports performance.

A project which was undertaken by student Matt Furber investigated whether foods with a high or low glycemic index had the best effect on 10 mile trial performance in males. Glycemic index (GI) is a ranking system for carbohydrates based on their immediate effects on blood glucose levels.

They found that the participant who followed a Low Glycemic Index (LGI) diet showed significant improvements in running performance as opposed to those who followed a High Glycemic Index (HGI) diet, which the researchers attributed to increases in blood glucose during the trial time.

“The improvements in performance were only seen when the carbohydrate loaded was low in GI,” said Matt. “The mechanism behind this may be due to the increases seen in blood glucose throughout the time trial.”

Another research project undertaken by postgraduate student, Nick Tiller, found that athletes could maximise their performance through drinking mixed carbohydrate drinks, as opposed to those containing single carbohydrates only.

“This is important because, for example, if you drink commercially available sports drinks, you can only ingest 70 grammes of maltodextrin per hour, which may not be enough to maximise your performance,” said Dr Jones. “But if you supplement this with, for example fructose, you can open up two channels and increase the amount of glucose available to your body.

“There is no doubt but that the foods that we eat have a significant effect on performance. Those in serious training need to give this more thought if they are to maximise their performance.”

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

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.

Im Focus: Writing and deleting magnets with lasers

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...

Im Focus: Gamma-ray flashes from plasma filaments

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.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
