EFFECT OF GENDER DIFFERENCE AND CIRCADIAN RHYTHM ON DIASTOLIC BLOOD PRESSURE FOR VOLLEYBALL PLAYERS

Öz

The purpose of the study was to find out the effect of gender difference and circadian rhythm on diastolic blood pressure for volleyball players. METHODS: To achieve the purpose, a total of thirty volleyball players [men n = 15 and women n = 15 ] age between 19 years and 22 years from Einstein College of Engineering, Tamil Nadu, India were selected as subjects. The two independent variables of gender and circadian variations and dependent variable of diastolic blood pressure were selected for this study. The experimental design used was static group factorial design. The data were collected at 02:00, 06:00, 10:00, 14:00, 18:00 and 22:00 hours on diastolic blood pressure by using Erkameter during the academic year of 2009 – 2010. Collected data were subjected to statistical analysis by using two-way factorial 2 x 6 Analysis of Variance ANOVA and Cosinor analysis. RESULTS: There was insignificant difference between genders, significant difference at different times of the day and insignificant circadian rhythmicity exists on diastolic blood pressure for women and significant for men. CONCLUSION: It is recommended to the physical educators to adopt the findings of this study while planning to improve sports skills for the players and athletes
