Gender Difference in Aerobic Capacity and the Contribution by Body Composition and Haemoglobin Concentration: A Study in Young Indian National Hockey Players.

INTRODUCTION

Although gender difference in aerobic capacity is known, the contributing factors have been researched seldom.

AIM

To investigate the gender gap and the contribution by percentage Body Fat (BF), Body Mass Index (BMI) and haemoglobin concentration Hb.

MATERIALS AND METHODS

The study was conducted on 30 (17 males, 13 females) training status matched young hockey players. Healthy players who were playing upto national level competition were included. BW (Body Weight), BF, BMI, LBM (Lean Body Mass), rHR (restring Heart Rate), HRR (Heart Rate Recovery), Hb, a/rVOmax (absolute/relative), a/rPWC (Physical Work Capacity) and RMR (Resting Metabolic Rate) were measured and analysed.

RESULTS

There was significant gender difference in the measured parameters. Difference in a/rVOmax remained significant even after controlling for BF, BMI and Hb. Multiple regression and correlation analysis revealed gender difference in VOmax/LBM was due to: BMI(31.91%)>BF(27.60%)>Hb(9.91%). BMI also significantly contributed 3.66% of VOmax/LBM variance, independent of that by gender. Difference in RMR was mainly related to LBM, BF and BMI.

CONCLUSION

The study provided an understanding for gender gap in aerobic capacity. Differences in BMI & BF were one of the main reasons.
