پاسخ عوامل هماتولوژیک به شدت‌های مختلف یک برنامه تمرین مقاومتی دایره‌ای در دانشجویان پسر ورزشکار

Abstractbackground and objectiveshematological parameters are influenced by physical activities. the purpose of this study was to survey the response of hematological factors to a circuit resistance training program with different intensities in athlete male students.materials and methodsin this experimental study, 24 athlete male students (age, 24.46 ± 0.48 years; weight, 75.58± 1.29 kg; height, 177.25 ± 1.32 cm) took part in this study voluntarily. subjects were randomly divided into three groups including three low, moderate and high intensities. each group contained 8 people. circuit resistance training program included ten stations, which took place in three sets with twenty seconds for each station. subjects were asked to fast for 12 hours. then, 10 ml blood samples pre and post exercise were taken from arm vena. all data were analyzed by using descriptive and inferential statistics (paired-samples t and anova) through spss 16 software. resultspost exercise results showed a significant increase in the values of hct and rbc in low intensity group, in hct, rbc, hb, and mcv in moderate intensity group, and in mcv, hb, hct, rbc, and wbc in high intensity group (p < 0.05). also, significant decrease was seen in the values of mchc and pv in moderate intensity group and pv, mchc, and mch in high intensity group (p < 0.05). conclusionsresults showed circuit resistance training with progressively low, moderate and high intensities could specifically influence hematologic factors. hence, it is recommended to coaches to consider intensity in designing circuit resistance training programs for athletes.
