RESUMO
OBJECTIVE: This study was aimed to determine the difference between the average blood pressure and heart rate for men's voley ball team before and after the match. METHOD: The research design used inferential analytical surveys with sample of 12 man voley ball team of the University of Timor (using the total sampling method). Collecting data was conducted by measure the respondent's blood pressure and heart rate before and after the voley ball match with the stipulation of 3 sets of wins. The tools used in this study to measure blood pressure is a stethoscope and OneMed Tensimeter Aneroid - Ash while the heart rate is measured using stop wacth. RESULT: Analysis using paired T test statistics, the results obtained there is a significant difference in the average of systolic blood pressure before and after the match [129.17mmHg (SD: 10.84) vs 115.00mmHg (SD: 6.74), p value=0.004]. There is no significant difference in the average of diastolic blood pressure before and after the match [79.17mmHg (SD: 2.89) vs 79.17mmHg (SD: 6.69), p value=1.000]. There is no significant difference in the average of heart rate between before and after the match [82.75times/min (SD: 6.12) vs 83.58times/min (SD: 5.58), p value=0.632]. CONCLUSIONS: Warming up before the match is important so that it gives a good chance of adaptation to the body. It is recommended to the competition committee to prepare a first aid team for an accident. And to further researchers in order to add other variables that affect blood pressure and heart rate in sports
