This study was conducted to determine the effect a six week aerobic training programme on some certain circulatory and respiratory parameters. Sixteen handball players, which average age 22.28±1.94 years, height 174.62±6.52 cm, and average weight 73.36±5.67 kg, participated in the study.  The handball players participated in regular running programme, which consists of a seven kilometers, 3 times per week during six weeks. The load intensity was 80% (percent).  One week before and after training programme, height, weight, body fat percent, resting hearth rate, systolic and diastolic blood pressure, vital capacity, forced vital capacity and forced expiratory volume at first second values were measured. The results were presented as mean and standard deviations. To compare the scores of before and after training student t test was used in dependent groups After the programme, some increases in weight, body fat percent, resting hearth rate, systolic  blood pressure and an decrease in diastolic blood pressure, vital capacity, forced vital capacity and forced expiratory volume at first second values were seen. As a result, after a six week aerobic training has a decreasing effect on circulatory parameters, an increasing effect on respiratory parameters.
