Hematologic ‎changes in student male soccer player’s response to a match‏ ‏in ‎moderate altitude with hot weather

Considering the nature of soccer field which is held in the open air and hosting cities with different weather conditions and changes in air temperature and altitude have an effect on the performance of the players, the purpose of this research is to investigate the hematological changes of male soccer player students in response to The soccer match was at medium altitude with hot weather. 10 student soccer players (except ‎Goalkeeper‎) with a mean age of 21.38± 0.42 years, Height 178 .76±4.23 cm, weight 70.33± ‎‎5.31 kg participated in the study. one hour before the match, immediately after and 24 hours ‎after the match, venous blood samples were taken for determination of white blood cells, red ‎blood cells, hemoglobin, hematocrit and Platelets‎ by CBC test. Descriptive statistics (the ‎mean ± standard deviation) and inferential statistics (ANOVA repeated measure) with contrast ‎methods (simple and repeat) were used for analysis data. This study ‎shows that there is significant difference for white blood cell (P=0.001) and platelets (P=0.003) ‎before, immediately after and 24 hours after football match. There is no significant difference ‎for red blood cells, hemoglobin, hematocrit and plasma volume. The physiological ‎pressure resulting from a football match played in hypoxic conditions because of altitude and ‎environmental heat continues for up to 24 hours following the game. Although these conditions ‎did not result in significant changes. To return white cells and platelets to normal levels, soccer ‎coaches are advised to consider a longer recovery period (over 24 hours) after a soccer match, ‎and to avoid intense and competitive training the following day.‎
