The main purpose of this study is to assess the relations between training loads and selected blood parameters in professional soccer players during a preseason sports camp. Fifteen professional soccer players (age: 24.3 ± 5.25 year; height: 182.6 ± 6.75 cm; weight: 76.4 ± 6.72 kg) participated in the 12-day training camp. All the training sessions and friendly games were accurately analyzed with a GPS system. Blood samples were taken from the players and analyzed before the camp (PRE), in the middle (MID), and one day after the camp (POST). Mean total distance covered by the players during the camp was 85,205 ± 2685 m, high-intensity running 12,454 ± 1873 m, and sprinting 639 ± 219 m. The highest aspartate transaminase (AST), lactate dehydrogenase (LDH), creatine kinase (CK), and C-reactive protein (CRP) values were observed after six days of the camp. The application of intensive training during a 12-day sports camp can be associated with chronic muscle pain with high activity of some blood enzymes (CK, AST) and a high concentration of myoglobin (Mb). During training camps longer than 10 days, it would be necessary to apply, every second or third day, one day of rest, and the training load should not exceed two units every day.

Exercise is advised for improving overall health and preventing many chronic diseases. Professional sportspersons practice regular strenuous exercise schedules for competitions. To maintain good performance high protein diet along with antioxidants is taken. Duration and severity of exercise affects various routine biochemical parameters. Biochemical tests including Blood Urea, Serum Creatinine, Serum Uric Acid, SGOT, SGPT, ALP, Serum Calcium, Serum Phosphorus, Serum total Protein, Serum Albumin, Lipid Profile( Triglycerides, Total cholesterol, HDL-Cholesterol, LDL-Cholesterol, VLDL-Cholesterol), Blood Glucose, Amylase and Serum Lactate was assessed in fifty professional athletes before and after exercise. Some parameters like urea, creatinine, glucose, lactate, calcium, ALP were affected by exercise and trainings which need to be considered for correct interpretation.
Oxidative Stress Biomarkers Response to Exercise in Brazilian Junior Soccer Players
Food and Nutrition Sciences, 2011
The purpose was to analyze biomarkers of oxidative stress and muscle damage in junior soccer players undergoing intermittent exercise to verify the biochemical changes. Ten trained, healthy male soccer players (age 18.3 ± 0.7 years, body mass 74.3 ± 7.4 kg, height 175.5 ± 6.7 cm, body mass index 24.14 ± 1.15 kg/m 2 ; mean ± SD) from the junior category of an elite Brazilian football association participated in this study. They accomplished a running test (Loughborough Intermittent Shuttle Test) which simulates common soccer activity patterns. Blood samples were collected before, during and immediately after the exercise for glucose, lactate, creatinine, urea, ascorbic acid, total plasma antioxidant potential, lipid hydroperoxides, malondialdehyde and creatine kinase concentrations. During the exercise no changes were observed in biomarkers, but, immediately after there was a significant decrease in total plasma antioxidant poten

The aim of the study was to determine the physical, physiological and nutritionalcharacteristics of female futsal players and selected markers of oxidative stress after their exercise training (Loughborough Intermittent Shuttle Test). Eight health female futsal players (age 21.3 ± 3.2 years, body mass 64.5 ± 5.6 kg, height 169.5 ± 6.5 cm, body mass index 22.45 ± 2.25 kg/m 2 ; mean ± SD) participated in this study. Blood samples were collected before, during and immediately after the exercise for glucose, lactate, ascorbic acid, total plasma antioxidant potential, lipid hydroperoxides, malondialdehyde and creatine kinase concentrations. Female futsal players appeared to meet caloric needs but failed to meet minimum carbohydrate and vitamin A, C and E recommendations. Immediately after the exercise there were an increase in lipid hydroperoxides (ranging from 9.32 ± 1.86 μmol•L-1 to 13.02 ± 1.62 μmol•L-1 , p < 0.05), malondialdehyde (ranging from 2.16 ± 0.45 nmol•L-1 to 3.29 ± 0.62 nmol•L-1 , p < 0.05) and creatine kinase (ranging from 118.14 ± 18.21 U.I..L-1 to 185.59 ± 6.96 U.I..L-1 , p < 0.05). In parallel, ascorbic acid and total plasma antioxidant potential had a slight decrease during and after exercise. Considering that alterations in oxidative stress parameters associated with inadequate ingestion of nutrients can affect health and performance of game players, further studies are needed to evaluate the inclusion of an nutritional education program and extent of biochemical changes through athlete's recovery period.
Scientific Reports
This study aimed to compare the effects of 1 × 1 small-sided games (SSGs) with different bout durations on external (ETL) and internal training loads (ITL) in youth soccer players. Twenty U18 players were divided into two groups performing six 1 × 1 SSGs with 30 and 45 s bout durations on a playing field of 10 by 15 m. ITL indices, including the percentage of maximum heart rate (HR), blood lactate (BLa) level, pH, bicarbonate (HCO3−) level, and base excess (BE) level, were measured at rest, after each SSG bout, and 15 and 30 min after the entire exercise protocol. ETL (Global Positioning System metrics) was recorded during all six SSG bouts. The analysis showed that the 45 s SSGs had a greater volume (large effect) but a lower training intensity (small to large effect) than the 30 s SSGs. A significant time effect (p < 0.05) was observed in all ITL indices and a significant group effect (F1, 18 = 8.84, p = 0.0082, ƞ2 = 0.33) in the HCO3− level only. Finally, the changes in the HR...

Studies on Ethno-Medicine, 2017
The goal of this study is exploring serum alterations related to acute coronary sendrom, muscle deterioration, hypoglysemia and the other variables in the serum of the fifteen footballers. Fifteen professional male footballers (mean (SD) age: 24 (4.4) years) were gathered from a 3 rd league team. Blood samples were collected from them before and after exercise. Blood samples were analyzed by standard methods and t he results were corrected in the biochemistry laboratory. The average pre-and post-exercise biochemical values of 15 footballers are found below. The glucose in the serum is 62.3 ± 3.9(before) and 69.5 ± 7.8(after) (P<0.05) for preand post-exercise, respectively. The urea in the serum is 36 ± 9.5(before) and 34.4 ± 9.2(after) (p> 0.05). The creatine in the serum is 0.9 ± 0.l(before) and 0.8 ± 0.9(after) (p>0.05). The CK in the serum is 309.9 ± 200.9(before) and 253 ± 149.7(after) (p>0.05). The CK-MB in the serum is 17.9 ± 6.3(before) and 14.5 ± 5.4(after)(p>0.05). The total bilirubin in the serum is 0.8 ± 0.4(before) and 0.8 ± 0.5(after) (p>0.05). The albumin in the serum is 4.1 ± 0.3(before) and 4.1 ± 0.2(after) (p>0.05). The BUN (blood urea nitrogen) in the serum is 16.7 ± 4.4(before) and 16.3 ± 4.5(after) (p>0.05). Although broad variety of biochemical perturbations is present during acute physical stress, many parameters remain within regular limits.

Annotation: The aim of this study was to investigate possible cardiovascular changes to chosen biochemical indices regarding specific forms of exercise (soccer, swimming etc) in boys 9 – 14 years old. The concentration levels of the following biochemical parameters were measured: reactionary protein (CRP), total antioxidant capacity (T.A.C), and Fibrinogen. Moreover, body fat percentage and body mass index were measured and maximum oxygen intake (VO2 max) was estimated. The sample comprised 168 boys, aged 10.33+0.88, 10.62+0.21, 11.68+0.11 and 10.71+0.24 years old respectively, who were classified into four Groups (1, 2, 3, 4) according to their level of physical activity. Blood samples were taken from all four Groups in the morning of the same day after a 12 – hour, all – night fasting. The statistical analysis of the results (variance analysis one way anova, post hoc – Bonferroni) showed statistically significant differences (a = 0.1) in the levels of reactionary protein (CRP), fi...
Muscle and Blood Metabolites during a Soccer Game
Medicine & Science in Sports & Exercise, 2006
Purpose: To examine muscle and blood metabolites during soccer match play and relate it to possible changes in sprint performance. Methods: Thirty-one Danish fourth division players took part in three friendly games. Blood samples were collected frequently during the game, and muscle biopsies were taken before and after the game as well as immediately after an intense period in each half. The players performed five 30-m sprints interspersed by 25-s recovery periods before the game and immediately after each half (N = 11) or after an intense exercise period in each half (N = 20). Results: Muscle lactate was 15.9 T 1.9 and 16.9 T 2.3 mmolIkg j1 d.w. during the first and second halves, respectively, with blood lactate being 6.0 T 0.4 and 5.0 T 0.4 mM, respectively. Muscle lactate was not correlated with blood lactate (r 2 = 0.06-0.25, P > 0.05). Muscle glycogen decreased (P G 0.05) from 449 T 23 to 255 T 22 mmolIkg j1 d.w. during the game, with 47 T 7% of the muscle fibers being completely or almost empty of glycogen after the game. Blood glucose remained elevated during the game, whereas plasma FFA increased (P G 0.05) from 0.45 T 0.05 to 1.37 T 0.23 mM. Mean sprint time was unaltered after the first half, but longer (P G 0.05) after the game (2.8 T 0.7%) as well as after intense periods in the first (1.6 T 0.6%) and second halves (3.6 T 0.5%). The decline in sprint performance during the game was not correlated with muscle lactate, muscle pH, or total glycogen content. Conclusion: Sprint performance is reduced both temporarily during a game and at the end of a soccer game. The latter finding may be explained by low glycogen levels in individual muscle fibers. Blood lactate is a poor indicator of muscle lactate during soccer match play.
