Special Issue Information

Dear Colleagues,

Nutritional interventions have been widely employed to optimize athletic performance across various modalities and populations. There is an extensive body of literature examining the overall energy balance, macronutrient and micronutrient intake, and dietary supplements in relation to different aspects of sports performance. These nutritional interventions have the potential to influence recovery processes, impact adaptation to varying loads and enhance athletic performance. The purpose is to analyze the relationship between dietary intake, sports supplementation and their effects on adaptation processes, recovery and athletic performance among diverse population groups. For instance, we may differentiate based on the type of sport, categorizing sports as predominantly aerobic, anaerobic or mixed. This Special Issue aims to collect the latest information about the effects and potential benefits of nutritional supplementation associated with exercise in populations of different ages and genders, as well as cases of special populations, such as individuals with diverse diseases.

Athletes are increasingly relying on natural supplements to improve athletic performance. Echinacea, a common herbal supplement, has been studied for its potential erythropoietin-enhancing effects, with mixed results in the literature. The purpose of this meta-analysis is to determine whether echinacea supplementation has erythropoietic or ergogenic effects in athletes. A search strategy was developed to identify trials studying the impact of echinacea supplementation on erythropoiesis and maximal oxygen uptake. The database search yielded 502 studies, 496 of which were excluded in the two-reviewer screening process. Six studies with a total of 107 athletes were included in the analysis. For hemoglobin and hematocrit levels, there were small, positive effect sizes when comparing the difference in pre- and post-intervention levels between the echinacea and placebo groups, at 0.38 (p = 0.02, 95% CI −0.04–0.80, I2 = 70%) and 0.34 (p < 0.01, 95% CI −0.10–0.78, I2 = 86%), respectively, though they did not reach statistical significance. There was also no statistically significant change in erythropoietin (effect size −0.29, p = 0.05, 95% CI −0.75–0.17, I2 = 67%) or maximal oxygen uptake (effect size −0.20, p = 0.95, 95% CI −0.60–0.21, I2 = 0%). Echinacea supplementation did not influence erythropoietin, hemoglobin, hematocrit, or maximal oxygen uptake in athletes; however, the evidence base is limited. Full article
