Special Issue Information

Dear Colleagues,

For this Special Issue of Metabolites, we invite researchers in the field of physical exercise and nutrition to contribute papers regarding the interactions between these variables and different outcomes linked to metabolism. Physical exercise and diet are important moderators of metabolism, capable of positively impacting human health. In this sense, submissions of studies that investigate the effectiveness of physical exercise and/or the impact of diet on metabolic health are especially welcome for this Special Issue. Furthermore, works on the effects of variables related to physical exercise and diet, such as physical fitness and eating behaviors, on metabolism are also solicited for inclusion in this Special Issue.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. 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. Metabolites is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs).

Background/Objectives: Infertility in both men and women can be significantly influenced by oxidative stress (OS), which occurs due to an imbalance between reactive oxygen species (ROS) and the body’s antioxidant defenses. In women, OS disrupts oocyte maturation, implantation, and the viability of the embryo; in men, it impairs sperm quality, reduces motility, and damages DNA integrity. This review explores existing research on how dietary and lifestyle interventions can reduce OS and enhance reproductive health outcomes. Methods: We conducted a comprehensive review of clinical, translational, and molecular studies exploring the mechanisms by which OS affects fertility, as well as the efficacy of nutritional and behavioral strategies. The interventions evaluated include weight management, regular exercise, micronutrient supplementation, antioxidant-rich diets, smoking and alcohol cessation, and stress-reduction techniques. Results: Specific dietary components such as zinc, selenium, vitamins C and E, and polyphenols have been found to neutralize reactive oxygen species (ROS) and enhance gamete function. OS is additionally reduced through lifestyle modifications, including minimizing harmful exposures, managing stress, and participating in moderate physical activity. Biomarkers such as ROS levels, total antioxidant capacity, 8-OHdG, and DNA fragmentation index are essential for assessing the effectiveness of interventions. Conclusions: Fertility in both sexes can be improved, and oxidative stress significantly reduced, through a multimodal approach incorporating dietary and lifestyle changes. There are encouraging opportunities to improve reproductive health through customized approaches that are informed by biomarker profiles. To incorporate these treatments into regular fertility care, future studies should concentrate on standardized procedures and long-term results. Full article

Introduction: Low levels of cardiorespiratory fitness (CRF) are associated with a greater risk of metabolic syndrome (MetS) in adolescence. In this sense, it is important to verify the strength of this association and the certainty that this evidence can be recommended. Objective: The objective of this paper is to summarize, through a systematic review and meta-analysis, the evidence available to verify the association between CRF and MetS in adolescents. Methods: PubMed, Embase, CINAHL, SPORTDiscus, LILACS, and Web of Science were searched until 20 August 2024. The risk of bias in each study was assessed via the AXIS tool, and the certainty of the evidence was assessed via the GRADE system. For the meta-analysis, the odds ratio (OR) was calculated with a 95% confidence interval. Results: Nine studies (7077 participants), all with a low risk of bias, were included in the systematic review. There was a high certainty of evidence that adolescents with low CRF have significantly greater odds of developing MetS (OR = 3.63 [CI 95%, 2.54 to 5.20]). The odds increase for low vs. moderate (OR = 4.23 [CI 95%, 2.64 to 6.78]) and low vs. high (OR = 8.03 [CI 95%, 3.20 to 20.18]) CRF are considered separately. The effect does not change according to the type of test used to assess CRF (p = 0.51). Conclusions: There is high certainty of evidence that adolescents with low CRF levels have significantly greater odds of developing MetS; therefore, it is essential that intervention strategies be designed to increase CRF in this population.
