Author(s): Dr. Deba Prasad Sahu
The purpose of the study was to investigate and compare on a set of basic anthropometric and physiological features of specific back court defensive and front court offensive inter university level male volleyball players. A total of twenty six inter university level volleyball players from Vidyasagar University, West Bengal were selected as subjects of this study who participated in the East Zone Inter University Volleyball Tournaments from the year 2013 to 2016. The players were categorized according to their court positions and playing role. They were mainly categorized as specific back court defensive players i. e. libero (N1=8) and front court offensive players which includes middle blockers and outside hitters (N2=18) in volleyball game. The variables selected for the study under anthropometric measurements were standing height, body weight, body mass index (BMI), total arm length, total leg length, palm length, elbow diameter, shoulder diameter, hip diameter, knee diameter, calf circumference, thigh circumference, chest circumference, biceps skin fold, triceps skin fold, subscapular skin fold, suprailliac skin fold and calf skin fold, while under physiological characteristics were resting heart rate, systolic blood pressure, diastolic blood pressure, percent body fat and resting metabolism. The subjects were assessed for height, body weight, lengths & circumferences, diameters and skin fold thickness through anthropometric rod, weighing machine, flexible steel tape, sliding caliper and skin fold caliper respectively. Body mass index (BMI) was calculated using the formula of weight in kg/height in meter square. Among the physiological characteristics percent body fat and resting metabolism were measured with a Karada Scan; Body Composition Monitor. Blood pressure (systolic & diastolic) and resting heart rate were measured by Panasonic Digital Blood Pressure Monitor. Data was analyzed using SPSS, (Version 20.0). Results of t-test revealed that specific front court volleyball players had significantly higher in height (p<0.05), body weight (p<0.05), total arm length (p<0.05), total leg length (p<0.05), palm length (p<0.05), elbow diameter (p<0.05), shoulder diameter (p<0.05), hip diameter (p<0.05), knee diameter (p<0.05), calf circumference (p<0.05), thigh circumference (p<0.05), chest circumference (p<0.05), biceps skin fold (p<0.05), triceps skin fold (p<0.05), subscapular skin fold (p<0.05), suprailliac skin fold (p<0.05) and calf skin fold (p<0.05), resting heart rate (p<0.05), percent body fat (p<0.05) and resting metabolism (p<0.05) as compared to specific back court defensive volleyball players. No significant differences was found in age, body mass index (BMI), systolic blood pressure and diastolic blood pressure between specific back court defensive and front court offensive volleyball players.
