The purpose of this study was to determine: (1) whether damage to liver and skeletal muscles occurs during a 100 km run; (2) whether the metabolic response to extreme exertion is related to the age or running speed of the participant; (3) whether it is possible to determine the optimal running speed and distance for long-distance runners’ health by examining biochemical parameters in venous blood. Fourteen experienced male amateur ultra-marathon runners, divided into two age groups, took part in a 100 km run. Blood samples for liver and skeletal muscle damage indexes were collected from the ulnar vein just before the run, after 25, 50, 75 and 100 km, and 24 hours after termination of the run. A considerable increase in alanine aminotransferase (ALT) and aspartate aminotransferase (AST) was observed with the distance covered (p < 0.05), which continued during recovery. An increase in the mean values of lactate dehydrogenase (LDH), creatine kinase (CK) and C-reactive protein (CRP) (p < 0.05) was observed with each sequential course. The biggest differences between the age groups were found for the activity of liver enzymes and LDH after completing 75 km as well as after 24 hours of recovery. It can be concluded that the response to extreme exertion deteriorates with age in terms of the active movement apparatus.

Soccer is one of the most widely played and complex sports in the world, where players need technical, tactical, and physical skills to succeed. Technical and tactical skills in soccer are highly dependent on the player's physical capacity. The selection, development and professional guidance of young players is a priority for many top soccer clubs in order to maintain their sporting and financial status. The aim of the present study was to determine hematological profile of youth national soccer teams and to compare the values of fifteen hematological parameters between 3 Serbian youth national teams (under 14, 15 and 16 years old), as well as between soccer players and nonathletes. 80 young soccer players and 30 non-athletes participated in the study. 15 hematologic parameters (WBC, RBC, HGB, HCT, PLT, MCV, MCH, MCHC, PDW, LYM%, MON%, GRAN%, LYM, MON, GRAN) were measured. In order to determine the significance of differences between the groups on a multivariate level a multivariate analysis of variance (MANOVA) was administered, and to test the differences between the groups on an univariate level a univariate analysis of variance (ANOVA) was applied. It was concluded that there is no significant difference in all the variables (WBC, Ly, Mo, Gr, PLT, HGB, HCT, etc), except RBC, probably due to age, androgen affection on erythropoesis, field positoning and diet. From a practical point of view, the clinician has to take into account not only age, but also training status of individuals when evaluating their blood tests.
