“…We did observe significant Polat 1439 increases of lymphocyte levels resulting from supplementation and exercise. In another study lymphocyte counts were elevated after hard exercise due to the acute phase inflammatory response it stimulated (Córdova et al, 2010). In another study, in spite of finding no changes in erythrocyte and leukocyte counts, zinc supplementation resulted in an increase of lymphocyte percentage in broiler chicks (Dönmez et al, 2002).…”

The purpose of the present study is to determine the effect of eight weeks zinc supplementation on the erythrocyte and leukocyte counts and other hematological parameters in male kick boxers. Twenty-four subjects were included in the study. They were equally divided into three groups as follows: Group EZ, training and receiving 2.5 mg/kg zinc supplement per day; Group SZ, receiving the zinc supplement but no training and Group E, who exercised but received no supplement. Erythrocyte, platelet and leukocyte counts, hematocrit, hemoglobin and the mean corpuscular volume (MCV) were determined in blood samples taken from each participant at rest and exhaustion. The erythrocyte count of Group EZ was significantly higher than in the E and SZ groups, p < 0.001. The number of leukocytes was higher in the two groups that trained. The hemoglobin and hematocrit levels were increased in the EZ group (p < 0.05).The platelet number increased with exhaustion in the E and EZ groups (p < 0.001). The MCV values were lower in group EZ as compared to the other two groups. The E and EZ subjects had higher neutrophil counts (p < 0.05).These results suggest that the combined effects of exercise and zinc supplementation have a positive effect in the hematological parameters of athletes, which may result in better performance and increased endurance.

“…Blood samples taken at rest before, during and after exhaustion were examined along with immune parameter analysis in volleyball players in a 4-month season. In that study, volleyball players had the same erythrocyte, hemoglobin and hematocrit values as the controls (Córdova et al, 2010).…”

“…Higher intensity and total volume as well as short rest intervals are associated with the magnitude of stress and muscle damage [2,9,19,23]. Numerous laboratory and field studies address changes in blood cortisol as response to different loads in different environments among athletes [1,3,4,6,8,10,16,18,21,23]. Recently Cunniffe and al.…”

“…Despite the informative content, frequent interventions have met limited practical application in competitive sport because of possible alteration in the regular course of the training cycle. Standardised repeated single interventions as longitudinal measures of hormonal, immunological and biochemical variables have been described in different sports, including team-game sports, as an expression of the impact of training [3,13,15,16,[18][19][20]23]. Analysis of longitudinal measurements can be carried out in comparison with an accepted reference interval but such an approach is not always productive in the case of athletes because of biological, procedural and environmental influences [12].…”

Close complex monitoring during the entire training period is essential for professional athletes to assess the effect of the training programme and to determine the quality of recovery. Follow-up of biochemical and hormonal variables throughout the season can help realize the abovementioned goals.Objectives: To determine baseline blood creatine kinase (CK) and cortisol (C) levels in professional basketball players before the beginning of regular training and to follow up the subsequent levels of blood C and CK over an entire season with analysis of dynamic changes in relation to individual coefficients of variation.Methods: Six professional basketball players were monitored from the first pre-season day to the end of a regular season. Blood samples were collected at six time points: before the pre-season, after the pre-season and four times during the in-season to determine blood C and CK concentrations.Results: Individual trends of the investigated variables were established and analysed with respect to the calculated intra-and inter-individual coefficients of variation for C and CK. Dynamic changes in C and CK levels coincided with changes in the content of the training process.Conclusion: In summary, the findings in the present study suggest that long-term intensive exercise in basketball has a significant influence on the blood cortisol profile. Muscle damage was associated with bodily collisions between the players but not with stress response in the current study.

“…While moderate activity may enhance immune function over sedentary levels, excessive, prolonged and high-intensity exercise may impair immune function 28 . Some studies have shown that relatively short periods of intense training (1 to 3 weeks), may reduce the function of innate immune 29,30 . In our study, two weeks of high intensity exercise increased the phagocytic capacity and cationic vesicles content from neutrophils and macrophages in the training diabetics rats (Table 3-4)).…”

Introduction: Type 1 diabetes is a metabolic disease associated to blood disturbances and disorder of the innate immune system functionality. Objective: This study investigated the effect of two weeks interval training on blood biochemistry and immunological parameters in rats with type 1 diabetes. Methods: Male Wistar rats were divided into three groups: sedentary (SE, n = 10), diabetic sedentary (DI, n = 10), diabetic interval training (DIT, n = 10). IV injection of streptozotocin (45 mg/kg) induced diabetes. Interval training consisted of swimming exercise for 30 seconds with 30 seconds of rest for 30 minutes three times a week during two weeks, with an overload of 15% of the total body mass. The evaluations performed were fasting blood glucose, triglycerides, very low-density lipoprotein cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and total cholesterol concentrations, phagocytic capacity, cationic vesicles content, superoxide anion, and production of hydrogen peroxide of blood neutrophils and peritoneal macrophages. Results: The results showed that two weeks interval training did not attenuate the hyperglycemic state at rest and did not decrease blood lipids in the DIT group. Diabetes increased the functionality of blood neutrophils and peritoneal macrophages in the DI group. Interval training increased the content of cationic vesicles and the phagocytic capacity of blood neutrophils and peritoneal macrophages in the DIT group. Conclusion: It was found that two weeks of interval training increased the functionality parameters of innate immune cells, although this has been insufficient to attenuate the biochemical disorders caused by diabetes.
