this demonstrates that carbohydrate was being effectively absorbed from the gut, it suggests that the additional glucose was being oxidized because of its availability rather than because it was required for sustained energy production. 11 , 12 Figure 2 —Substrate oxidation rates. Rates of fat and

environmental factors such as raw material availability and economic variables is a necessity for business people, entrepreneurs, or managers. Adaptation is believed to be compulsory for business sustainability and likely reduces the risk of suffering an organizational crisis. In elite sports, practitioners

This new knowledge about attentional focus is also in line with recent psychophysiological models of endurance performance, 10 – 12 which show that the athlete’s effort is directly influenced by psychological

Ultimately, PCM treatment provided a sustained decrease in intramuscular temperature that was maintained for the 3 hours of application (Figure  2 ) and a more gradual recovery (Figure  3 ). However
