Special Issue Information

Dear Colleagues,

For athletes, especially those who are young, a well-balanced diet containing an adequate amount of macronutrients and micronutrients should be able to meet most of the athletes’ needs and support their physical fitness, sporting performance, as well as muscle growth and repair. Proper nutrition is essential given the high level of stress faced by the bodies of athletes. 

Different dietary patterns have been explored with respect to cardiorespiratory fitness, physical strength, sports performance and muscle recovery in athletes. Some commonly explored diets include high-protein diets and ketogenic diets, as well as a variety of antioxidant, anti-stress and anti-inflammatory dietary strategies. It is also essential to highlight the increased reliance of athletes on sports foods and dietary supplements to optimize training adaptation and boost performance. Most of the time, those supplements are taken with little/no professional guidance and do not provide any additional benefits.  

This Special Issue aims to communicate up-to-date evidence-based knowledge on the interaction between different dietary approaches and physical fitness, and their role in optimizing performance and supporting fast recovery in athletes of different age groups, involved in different types of sports. All forms of manuscripts, including experimental papers, narrative reviews, systematic reviews, meta-analyses and short communications, are welcomed.

We look forward to receiving your submissions.

Dr. Dalia El Khoury

Iron is an essential micronutrient for athletes, intricately linked to their performance, by regulating cellular respiration and metabolism. Impaired iron levels in the body can significantly hinder athletic performance. The increased demand for iron due to exercise, coupled with potential dietary iron insufficiencies, particularly among endurance athletes, amplifies the risk of iron deficiency. Moreover, prolonged exercise can impact iron absorption, utilization, storage, and overall iron concentrations in an athlete. On the contrary, iron overload may initially lead to enhanced performance; however, chronic excess iron intake or underlying genetic conditions can lead to detrimental health consequences and may negatively impact athletic performance. Excess iron induces oxidative damage, not only compromising muscle function and recovery, but also affecting various tissues and organs in the body. This narrative review delineates the complex relationship between exercise and iron metabolism, and its profound effects on athletic performance. The article also provides guidance on managing iron intake through dietary adjustments, oral iron supplementation for performance enhancement in cases of deficiency, and strategies for addressing iron overload in athletes. Current research is focused on augmenting iron absorption by standardizing the route of administration while minimizing side effects. Additionally, there is ongoing work to identify inhibitors and activators that affect iron absorption, aiming to optimize the body’s iron levels from dietary sources, supplements, and chelators. In summary, by refining the athletic diet, considering the timing and dosage of iron supplements for deficiency, and implementing chelation therapies for iron overload, we can effectively enhance athletic performance and overall well-being.
