Special Issue Information
Dear Colleagues,
Carbohydrate consumption has been known to be associated with exercise performance since the early 20th century. The availability of carbohydrate as a substrate for skeletal muscle contraction and the central nervous system (e.g., the brain) is important for exercise performance in endurance sports. Performance-enhancing effects are often achieved by intaking carbohydrates before exercise to replenish muscle and liver glycogen stores and to maintain blood glucose levels and glucose oxidation rates during prolonged exercise. Along with carbohydrate, fat is also an important fuel for energy metabolism. Research has proved that as the total energy demand of the body increases with exercise intensity, the proportion of carbohydrate involved in energy supply gradually increases, while the proportion of fat gradually decreases. As fat stores are much larger than carbohydrates, endurance athletes tend to utilize as much of their fat stores as possible. Researchers, coaches and athletes are trying to develop nutritional strategies to improve fat metabolism and reduce reliance on carbohydrate stores, such as fasting, high-fat/low-carbohydrate diets, etc. Additionally, some nutritional supplements such as caffeine and carnitine are thought to have a positive effect on promoting fat oxidation. Furthermore, carbohydrate is expected to attenuate exercise-induced inflammation. Insufficient carbohydrate intake with decreased muscle and liver glycogen stores facilitates inflammation, which is associated with augmented fatigue and impaired iron metabolism. This special issue aims to collect the latest discussions about the impact of nutritional manipulation on substrate oxidation, fatigue and inflammation in the field of exercise.

Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.
