Special Issue Information

Dear Colleagues,

Fatigue is a common multifaceted symptom experienced by the majority of people throughout their lifespan. Since the publication of Angelo Mosso’s book in 1891 entitled La Fatica, many studies have sought to increase our knowledge on the different forms of fatigue (e.g., acute fatigue occurring after physical or mental exercises, or chronic fatigue felt by health-compromised individuals) in various experimental conditions. A better understanding of fatigue can help coaches and clinicians to implement targeted exercise training programs for specific populations. For example, fatigue can limit sport performance, but exercise training has the potential to delay the occurrence of fatigue. Under various pathological conditions, exercise training may help patients overcome the symptom of fatigue that influences their quality of life and daily routine. Hence, the aim of this Special Issue is to present original articles that investigate the effect of exercise training programs on fatigue, with a particular emphasis on neuromuscular fatigue, defined as a diminution in maximal force or power production in response to acute exercise. Studies investigating the influence of training programs in healthy and/or health-compromised individuals are encouraged. Literature reviews and meta-analyses focusing on this research topic will be also considered. Accepted articles will be published in the International Journal of Environmental Research and Public Health.

Gradual Strength Training Improves Sleep Quality, Physical Function and Pain in Women with Fibromyalgia

by Cristina Maestre-Cascales, Antonio Castillo-Paredes, Nuria Romero-Parra, José Carmelo Adsuar and Jorge Carlos-Vivas

Int. J. Environ. Res. Public Health 2022, 19(23), 15662; https://doi.org/10.3390/ijerph192315662 - 25 Nov 2022

Abstract

Background: Fibromyalgia (FM) is characterized by chronic and generalized musculoskeletal pain. There is currently no cure for FM, but alternative treatments are available. Among them, gradual strength training programs (ST) which on daily activities are a valid option to improve some of the pronounced symptoms of FM that affect quality of life, such as fatigue, pain, sleep quality, and physical function. However, there is a need for more information on optimal training programs to improve anxiety and fatigue symptoms. Aim: To analyze the effects of a 24-week gradual and progressive ST on sleep quality, fatigue, pain domains, physical function, and anxiety-state. Methods: 41 women with FM participated in the 24 weeks of intervention based on gradual and progressive ST. Two, 60 min, training sessions per week were con-ducted. Participants were evaluated before the ST program (week 0), in week 12 and at the end of the ST program (week 24). The Revised Fibromyalgia Impact Questionnaire was used to assess sleep quality and fatigue scales. Anxiety-state was evaluated with the State Anxiety Inventory, and pain domains by means of the Brief Pain Inventory. Senior Fitness Test was used for physical function measurements. One-way analysis of variance (ANOVA) was applied to assess the mean differences between phases, and Spearman’s correlations were used to assess the associations between physical and psychological symptoms, and physical function. Results: The results demonstrated that 24 weeks of ST improves physical function, sleep quality and pain domains (p ≤ 0.05). Higher anxiety and pain interference scores were related to worsening physical function. Conclusions: Gradual ST significantly improves sleep quality, pain, and physical function, but not anxiety and fatigue. Full article

Abstract

Studies have found that the prevalence of chronic fatigue syndrome (CFS) in adolescents has continued to increase over the years, affecting learning and physical health. High school is a critical stage for adolescents to grow and mature. There are inadequate detection and rehabilitation methods for CFS due to an insufficient understanding of the physiological mechanisms of CFS. The purpose of this study was to evaluate the effect and metabolic mechanisms of an aerobic running intervention program for high school students with CFS. Forty-six male high school students with CFS were randomly assigned to the exercise intervention group (EI) and control group (CFS). Twenty-four age- and sex-matched healthy male students were recruited as healthy controls (HCs). The EI group received the aerobic intervention for 12 weeks, three times a week, in 45-min sessions; the CFS group maintained their daily routines as normal. The outcome measures included fatigue symptoms and oxidation levels. Keratin was extracted from the nails of all participants, and the oxidation level was assessed by measuring the content of 3-Nitrotyrosine (3-NT) in the keratin by ultraviolet spectrophotometry. All participants’ morning urine was collected to analyze urinary differential metabolites by the GC-MS technique before and after the intervention, and MetaboAnalyst 5.0 was used for pathway analysis. Compared with before the intervention, the fatigue score and 3-NT level in the EI group were significantly decreased after the intervention. The CFS group was screened for 20 differential metabolites involving the disruption of six metabolic pathways, including arginine biosynthesis, glycerolipid metabolism, pentose phosphate pathway, purine metabolism, β-alanine metabolism, and arginine and proline metabolism. After the intervention, 21 differential metabolites were screened, involved in alterations in three metabolic pathways: beta-alanine metabolism, pentose phosphate metabolism, and arginine and proline metabolism. Aerobic exercise was found to lessen fatigue symptoms and oxidative levels in students with CFS, which may be related to the regulation of putrescine (arginine and proline metabolism), 6-Phospho-D-Gluconate (starch and sucrose metabolism pathway), and Pentose (phosphate metabolism pathway).

Abstract

Background: Recent research indicates that both endocannabinoids (eCB) and heart rate variability (HRV) are associated with stress-induced experiences. However, these underlying mechanisms are not elucidated. The present study aims to investigate whether exposure to acute and chronic stress conditions can give rise to measurable changes, both to the peripheral eCB ligands and HRV. Methods: Thirteen candidates under intense preparation for their enlistment in the Hellenic Navy SEALs (HNS) participated in the study. All subjects underwent mental state examination, while HRV variables in time and frequency domain recordings were acquired. Furthermore, at baseline and 30 days after prolonged and intensive physical exercise, hair was collected to measure eCB ligands, such as anandamide (AEA), 2-arachidonoylglycerol (2-AG), and the N-acyl ethanolamine (NAE) molecules: palmitoylethanolamide (PEA) and oleoylethanolamide (OEA). Results: Comparing basal hair concentrations of eCB ligands before and after intense physical exercise, we found that AEA, PEA, and OEA were notably increased, whereas no differences were observed regarding the ligand 2-AG. Furthermore, there were observed associations between the concentrations of peripheral eCB ligands, both at baseline and after the prolonged physical exercise and the time and frequency domains of HRV. Conclusions: These findings suggest that endocannabinoid–HRV interrelations might share a short-term, and long-term adaptability of the changes in self-regulation associated with stress. Further studies will be required to determine the validity of peripheral eCB signaling and HRV as a biomarker for different aspects of the stress response. Full article
