Autonomic functions of college boys and girls (A comparative study)

The objective of the study was to compare between college boys and girls in regard to the special reference to advance sportsperson (who plays games/sports at national level), inter-mediate sportsperson (who plays games/sports at inter-college level) and non- sportsperson (those who don’t play any sports at all). It was hypothesised that different level of games/sports participation / non-participation will have sex difference in regard to selected autonomic function variables. Sample comprises advance sports boys= 22, advance sports girls= 6, inter-mediate boys= 37, inter-mediate sports girls= 20, non-sports boys= 27 and non-sports girls= 22. Ages of the sample ranged from 17 to 21 years of same socio-economic status belonging to different games/sports. Students were asked to come with two hours fasting before the test. No medication was taken before 48 hours of the testing. Subjects rested for 30 minutes before the commencement of the test and then heart rate variability (HRV) was recorded, which quantifies autonomic drive to the myocardium variables were extracted by computing time domain analysis and frequency domain analysis. Collected data was computed with Mean, Standard Deviation, Levene's Test for Equality of Variances (‘t’ test). The hypothesis was tested at 0,05 level of significance. The study concluded that Mean heart rate for advance sports (boys and girls) and SDNN, Mean Heart Rate, RMMSD, pNN50 count and Total (Absolute Power) for non- sports (boys and girls) with different level of games/sports participation had sex differences.
