Effects of morning and nocturnal soccer matches on levels of some trace elements in young trained males

Abstract

The aim of this study was to comparatively evaluate effect of morning and nocturnal soccer matches induced metabolic stress on plasma levels of iron (Fe), copper (Cu) and zinc (Zn). Twenty male footballers performed two soccer matches in morning and at night on different days. Blood samples were taken before and after match. The levels of Fe, Zn and Cu were measured through an atomic absorption spectrophotometry. Metabolic stress was evaluated by altered malondialdehyde (MDA) levels that measured using High Performance Liquid Chromatography. In morning and at nocturnal soccer matches, levels of MDA (36% and 27%), Fe (37.4% and 38.9%) and Cu (34.8% and 26.8%) were all increased in all subjects, respectively. However, Zn level decreased-4.5 % in morning (n=10 subjects) and-9.4% at nocturnal (n=12 subjects) soccer matches. In addition, Cu/Zn ratio increased significantly 46.6% in morning and 36.6% at nocturnal soccer matches. Soccer match has significant effects on levels of MDA, Fe and Cu but not Zn levels. The results of this study showed that morning soccer match significantly alters levels of MDA and Cu and Cu/Zn ratio compared to nocturnal soccer match.

Extracellular and Intracellular Concentrations of Molybdenum and Zinc in Soccer Players: Sex Differences

“…However, Metin et al [ 24 ] reported no differences in plasma Zn concentrations between groups, similar to those reported by the previous authors. No differences were observed either when comparing the time of match play in plasma Zn concentrations [ 23 ].…”

“…In this regard, it has been observed that serum Mo and Zn concentrations differ among sports modalities and training levels [ 21 , 22 ], as well as erythrocyte concentrations [ 7 ]. In soccer players, Algul et al [ 23 ] reported that plasma Zn concentrations decreased at the end of a match, whether the game was played in the morning or in the evening. Metin et al [ 24 ] observed no differences in Zn concentrations between male and sedentary soccer players.…”

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

“…In soccer players, research is more scarce. In relation to the above, previous authors reported increases with respect to basal values in Cu concentrations after the end of a soccer match regardless of the time of the match (morning or evening) [ 24 ]. However, Metin et al [ 25 ] reported that soccer players presented lower plasma Cu concentrations in relation to the control group, being in the same line as that reported by Toro-Román et al [ 20 ].…”

“…It is generally accepted that physical activity is a valuable tool in the preventative and treatment strategy for many cardiorespiratory and metabolic diseases and other chronic diseases (Ozcelik et al, 2015& Sietsema et al, 2020. In addition to many beneficial effects of exercise on improvement of body composition, increased fat oxidation, insulin homeostasis, exercise has significant impacts on increased metabolic stress, impairment of oxidant antioxidant status and disarranged of levels of some trace elements (Algul et al, 2019). Zinc (Zn) is one of the important trace elements that have significant roles in energy metabolism and antioxidant effects (Gulbahce et al, 2021& Ugurlu et al, 2022.…”
