Sex Differences in Copper Concentrations during a Sports Season in Soccer Players

Physical training produces changes in the concentrations of trace mineral elements. Sex differences in copper (Cu) concentrations in athletes are scarce. The objectives of this study were (i) to analyze changes in intracellular (erythrocytes and platelets) and extracellular (plasma and urine) Cu concentrations during a sports season in soccer players and (ii) to analyze sex differences. A total of 46 soccer players (22 men and 24 women) participated in the study. Three assessments were performed throughout the sports season. Anthropometry, body composition, nutritional intake, physical condition, female hormones (menstrual cycle) and hematology were evaluated, as well as Cu determination (plasma, urine, erythrocytes, and platelets). Regarding longitudinal differences, there were discrepancies in plasma, urine, absolute erythrocyte, and absolute platelet Cu concentrations (p < 0.05). There were differences between sexes in Cu concentrations in urine, erythrocytes relative to cell number and in platelets relative to cell number (p < 0.05). During a sports season, there are changes in Cu concentrations in soccer players. Likewise, there could be sex differences in urinary, erythrocyte and platelet Cu concentrations.

“…It is currently unclear whether urinary molybdenum content is indicative of reduced molybdenum uptake to bodily tissues, or increased molybdenum exposure. More recently, the literature has begun to explore intracellular molybdenum content alongside blood and urine; Toro-Roman and colleagues found the intracellular content of platelets and erythrocytes substantially higher than concentrations in plasma, but it is not known whether molybdate, the molybdenum cofactor, or another molybdenum complex was detected [134]. Lastly, a two-arm study investigating the effects of a 12-day nutritional intervention with molybdenum biofortified lettuce (8 mg/100 g fresh weight consumed per day) significantly reduced fasting glucose, insulin and insulin resistance, with no change in urinary output of molybdenum between groups, which may be due to the rapid clearance of molybdenum shortly after ingestion.…”

Does the Micronutrient Molybdenum Have a Role in Gestational Complications and Placental Health?

et al. 2023

Molybdenum is an essential trace element for human health and survival, with molybdenum-containing enzymes catalysing multiple reactions in the metabolism of purines, aldehydes, and sulfur-containing amino acids. Recommended daily intakes vary globally, with molybdenum primarily sourced through the diet, and supplementation is not common. Although the benefits of molybdenum as an anti-diabetic and antioxidant inducer have been reported in the literature, there are conflicting data on the benefits of molybdenum for chronic diseases. Overexposure and deficiency can result in adverse health outcomes and mortality, although physiological doses remain largely unexplored in relation to human health. The lack of knowledge surrounding molybdenum intake and the role it plays in physiology is compounded during pregnancy. As pregnancy progresses, micronutrient demand increases, and diet is an established factor in programming gestational outcomes and maternal health. This review summarises the current literature concerning varied recommendations on molybdenum intake, the role of molybdenum and molybdoenzymes in physiology, and the contribution these play in gestational outcomes.

Performance in soccer has been associated with specific morphological characteristics. Few studies have simultaneously compared the relationships between physical fitness and body composition in both sexes. This study aimed (i) to analyze the differences in anthropometric parameters, body composition, and physical fitness between sexes and playing position in soccer players and (ii) to determine the relationship among anthropometric and body composition parameters to physical fitness parameters according to sex. A total of 50 soccer players (men: n = 26; women: n = 24), participated in the study. Assessments of nutritional intake, anthropometry, body composition, and physical fitness (isometric strength, maximal aerobic capacity, and vertical jump) were carried out. Differences between sexes were observed in all anthropometric and body composition parameters (p < 0.001). There were differences between midfielders and forwards in fat percentage (p < 0.05). Regarding physical condition, differences were found between sexes in all tests performed (p < 0.001). In men soccer players, there were significant correlations between body composition and aerobic capacity (p < 0.05), while in women soccer players, there were correlations with isometric strength tests (p < 0.05). Anthropometry, body composition, and physical fitness differed between sexes. Fat percentages were different among playing positions. There were relationships between anthropometry and body composition with physical fitness. Knowledge of anthropometric and fitness characteristics by playing position and gender in soccer players could help develop specific training programs.
