football participation requires considerable utilization of both aerobic and anaerobic energy systems to match the high energetic demands of the sport. the consequent stresses imposed on the physiological and metabolic systems carries players to the threshold of exhaustion during match-play, from which they are required to recover in preparation for the subsequent game. a high number of players...

In an increasing range of research fields there is a strong demand of high-intensity tunable monochromatic X-ray sources. A promising new approach for the production of tunable high-intensity monochromatic beams in the hard X-ray region is the use of electron accelerators of moderate energy (10 MeV range). We developed at the 15 MeV linear electron accelerator of the Ghent University a monochro...

Performance in intense exercise events, such as Olympic rowing, swimming, kayak, track running and track cycling events, involves energy contribution from aerobic and anaerobic sources. As aerobic energy supply dominates the total energy requirements after ∼75s of near maximal effort, and has the greatest potential for improvement with training, the majority of training for these events is gene...

The effects of in-season, high-intensity interval training on professional male soccer players' running performances were investigated. Twenty-two subjects participated in 2 consecutive training periods of 10 weeks. The first period was considered a control period and was compared with a period where 2 high-intensity interval training exercises were included in the usual training program. Inter...

The main objective of the present study was to evaluate the short-term effects of exercise of different intensities on energy intake. Eleven young men were submitted to three randomly assigned sessions (one control and two exercise sessions) in which they ate, ad libitum, foods from a buffet-type meal. The energy cost of exercise was the same in the two exercise sessions. Results showed that th...

This paper analyzes the relationship between factor substitutability and the energy intensity of manufacturing firms. Specifically, we compare the degree of substitutability between the input factors capital, labor, energy, and material for firms with low, medium, and high energy cost shares using a panel of Swiss manufacturing companies covering the period from 1997 to 2008. Our findings indic...
