“…The increase in the number of leukocytes after short-and long-lasting exercise described in the literature was not observed 1 week after the contests in this study (7,12,14,15,19,22). It also became clear that in the blood samples of the present study there was no change due to training or contests in the number of lymphocytes and neutrophils, but the number of eosinophils, basophils, and monocytes showed an increase I week after the contests (18,21). This can probably be explained as post-exercise stress.…”

In the present study 60 males and 18 females were monitored during an 18- to 20-month training period, during which the training distance was gradually increased. The training period was divided into three periods of 6, 5, and 7 months, respectively. The first, second, and third periods were concluded with a 15-, 25-, and 42-km road race, respectively. The competitive distance always exceeded the maximal distance covered in any previous training session. The effect of training was investigated for the number of leukocytes, number of the subpopulations, and the percentage of white cells with a higher peroxidase activity (HPX cells). The measuring points were the start of the study (used as a reference value) and 1 week before and 1 week after three contests (15, 25, and 42 km). The results of all measuring points were compared transversely and longitudinally. Transversely the leukocytes hardly changed in the course of the study both in males and females, except a decrease of HPX cells. Longitudinally it appeared that Nvar and CVp90 of the numbers of leukocytes could not be calculated in males or in females. These findings suggest that a homogeneous population of leukocytes developed with respect to number and age.

“…between 0830 and 1030 h, therefore, the time factor cannot explain the cortisol difference between groups in this study. The evolution of cortisol during exercise is controversial; in some papers it rises during exercise [15-171, while in others, and in this study, no change was observed [4,18,191. In addition, after exogenous stimulation of the supra-renal cortex, the plasmatic cortisol response reached its maximum 30-60 min after the initial stimulation and then remained the same for about 1 h [8].…”

The influence of exercise on hormonal and total white blood cells (WBC), lymphocytes (L). Granulocytes (GR), and platelet (P) count responses was studied in: twenty-five patients with chronic airway obstruction (CAO, 47 +/- 1.8 years, mean +/- SEM) and thirteen normal subjects (N, 36 +/- 2.6 years). They performed a submaximal (40 W) and a maximal exercise (VO2max). Arterial blood samples were taken at rest, 40 W, and VO2max. [H+], PaCO2, PaO2 haematocrit (Hct), [Hb], P, total platelet volume (TPV), WBC, GR, L, and total red blood cells (RBC) were measured. At rest, WBC, GR, P and TPV were higher in CAO patients, whilst PaO2 and cortisol were lower. At 40 W, when compared to values obtained at rest, WBC, GR, L, P and TPV were increased in both groups; WBC, GR, P and TPV were higher in CAO patients. VO2max of CAO patients represented 54% of that of controls. At VO2max, Hct, [Hb] and RBC were approximately 10% higher than at rest in both groups, whilst changes were more significant in normals for WBC (CAO = 55%, N = 76%), lymphocytes (CAO = 83%, N = 105%), GR, (CAO = 37%; N = 51%), platelets (CAO = 23%, N = 29%), TPV (CAO = 25.4%, N = 35%), [H+] (CAO = 43%, N = 38%) and ACTH (CAO = 82%, N = 139%). PaO2 and cortisol did not differ between groups. PaCO2 and platelets however, were higher in the CAO group.(ABSTRACT TRUNCATED AT 250 WORDS)

“…Similarly, Ali, Ullah & Jan (2003) showed that all the WBC populations increased immediately after strenuous running for 2–3 min at 7% grade, all populations but lymphocytes decreasing after a 30 min recovery. Oyster (1980) also reported a trend toward eosinopenia during a 15‐min tennis competition.…”

“…, 1989), a 1600‐km ultramarathon (Fallon et al. , 1999) or following an acute bulk of anaerobic exercise (Oyster, 1980; Christensen & Hill, 1987; Ali, Ullah & Jan, 2003), but little information is available on the acute changes of leucocytes after a 21‐km half‐marathon, which is one of the most popular form of recreational sport in the general population of physically active individuals. To further clarify this issue, complete blood cell count was assessed on trained, middle‐aged males before a half‐marathon run, immediately after and 3, 6, 24 h thereafter.…”

There is growing interest on haematological changes following elite and recreation sports. However, no information is available on leucocyte variations after an intermediate-distance run. Complete blood cell count was assessed on 17 trained, middle-aged males before a 21-km half-marathon, at the end and 3, 6, 24 h thereafter. Statistically significant variations by one-way analysis of variance were observed for all the parameters tested. Haematocrit, haemoglobin and red blood cells and platelet count increased significantly by the end of the run and returned to pre-run values 3 h thereafter. White blood cells, neutrophils, monocytes and basophils counts increased after the run, reached the peak at 3 h and returned to the baseline after 24 h. Conversely, the eosinophils count significantly decreased after the run, reached a nadir at 3 h and slowly returned to pre-run values at 24 h. The lymphocytes count significantly increased after the run, decreased 3 h thereafter and returned to pre-run values after 6 h. These results show that an intermediate-distance run, which is a popular form of recreational sports worldwide, is associated with transitory leucocytosis, neutrophilia, monocytosis and basophilia, but it also induces acute eosinopenia, all changes being completely reversed 24 h thereafter.
