“…Similarly, Maynar et al [ 15 ] found no differences in basal levels between athletes and the CG. However, other authors reported higher urinary Zn concentrations after Zn supplementation [ 63 ], after strenuous exercise [ 22 , 64 ] or after a repeated heat exposure program [ 20 ].…”

Background Physical exercise affects zinc (Zn) homeostasis. This study aimed to analyze the influence of physical training on extracellular (serum, plasma, and urine) and intracellular (erythrocytes and platelets) concentrations of Zn. Methods Forty young men, divided into a training group (TG; n = 20; 18.15 ± 0.27 years; 68.59 ± 4.18 kg; 1.76 ± 0.04 m) and a control group (CG; n = 20; 19.25 ± 0.39 years; 73.45 ± 9.04 kg; 1.79 ± 0.06 m), participated in this study. The TG was formed by semiprofessional soccer players from a youth category with a regular training plan of 10 h/week. The CG was formed by healthy men who did not practice physical exercise and had not followed any specific training plan. Plasma, serum, urine, erythrocyte, and platelet samples of Zn were obtained and analyzed by inductively coupled plasma mass spectrometry. Results The TG showed elevated plasma Zn concentrations (p < 0.01) despite similar intakes. However, TG showed reduced absolute (p < 0.01) and relative (p < 0.05) Zn concentrations in erythrocytes. Conclusions Athletes who underwent regular physical training showed elevated plasma and reduced erythrocyte Zn concentrations despite similar intakes to the CG.

“…Among the novelties of the present study are the longitudinal comparison of Cu concentrations in the different biological matrices simultaneously and the comparisons between sexes in athletes. Studies that have investigated the influence of exercise on Cu concentrations in athletes have analyzed one [ 36 , 37 , 38 ], two [ 12 , 39 ] or three compartments [ 40 ]. Recently, Toro-Román et al [ 20 ] studied Cu concentrations in up to five compartments in soccer players to obtain a complete assessment, observing important discrepancies between biological matrices.…”

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

et al. 2023

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.

“…In the study of eight weeks of aerobic exercise program in obese and overweight individuals, Çakmakçı et al (2010) found that the participants had variations in hematological parameters, and as a result of the research, acute and intense exercises had more impact on hematological parameters than chronic and low intensity exercises [18]. Skarpańska-Stejnborn et al, (2015) found that an intensive exercise program implemented in the study involving twenty elite rowing athletes caused changes in the athletes ' hematological parameters [19]. In another study, Nishiie-Yano et al, (2019) found that regular judo training creates significant changes in athletes ' hematological parameters [20].…”

Objective: Following acute exercises, changes in mineral and hematological concentrations are observed in the organism depending on the exercise, but regular and submaximal exercises do not fully reveal the mineral and hematological effects. This study was conducted to determine the effects of volleyball training on mineral metabolism and hematological parameters over a period of three months. Method:The research group included 20 healthy male volunteers in the 13-16 age group. A training program of 80 minutes per day, 4 days per week, for three months was applied to the athletes who participated in the study. Blood samples were taken twice before and at the end of the training sessions from the resting athletes. Sodium, potassium, chlorine, calcium, magnesium, WBC, RBC, HGB, HCT, MCV, MCH, MCHC, PLT, MPV and PDW levels were determined in the blood samples collected. The data were analyzed using the SPSS 22 package program. The Paired Samples t-test was used to compare the research group's pre-final test data. Significance was considered to be p>0.05. Finding: The analysis showed that the research group had statistically significant differences in sodium, chlorine, phosphorus, magnesium, RBC, HCT, MCV, MCH, MCHC, MPV and PCT levels (p<0.05) and no statistically significant differences in potassium, calcium, WBC, HGB, PLT, RDW-CV and PDW levels (p>0.05). Conclusion:As a result, volleyball training over a long period of time has been observed to cause changes in mineral metabolism and some hematological parameters. It was found that the regular training schedule caused differences in some mineral and whole blood values. In the light of this information, we believe that long-term adolescent training will have a positive impact on the health of athletes.
