Abstract
Stress is the reaction of the body to a change that requires physical, mental or emotional adjustments.
Individual differences in stress reactivity are a potentially important risk factor for gender-specific health
problems in men and women. The Autonomic regulation of the cardiovascular system is most commonly
affected by stress and is assessed by means of short term heart rate variability (HRV).The present study
was undertaken to investigate the difference in the cardiovascular Autonomic Nervous System response to
mental stress between the genders using HRV as tool. We compared the mean RR interval, Blood pressure
and indices of HRV during the StroopColor Word Test (SCWT).Twenty five male (Age19.52±0.714, BMI
22.73±2 kg/m2) and twenty five female subjects (Age 19.80±0.65, BMI 22.39±1.9) performed SCWT for five
minutes. Blood Pressure (SBP p<0.01, DBP p<0.042) & Mean HR (p<0.010) values showed statistically
significant difference among the genders. HRV indices like LFms2 (p<0.051), HF nu (p<0.029) and LF/HF
ratio (p<0.025, p<0.052) show statistically significant difference among the genders. The response by the
cardiovascular system to a simple mental stressor exhibits difference among the genders.
