Abstract
The purpose of this study was to profiled the body composition, anthropometric and physical fitness qualities of Iranian national adolescent volleyball players, and quantified relationships between these characteristics. The sample of this study was 40 national adolescent volleyball players (Age: 17.9±0.3). Body composition factors: (weight, BMI, WHR, body fat percentage, muscle mass) and Anthropometric indexes: Girths (waist, hip, abdomen, forearm, arm, thigh, calf), Breadths (wrist, humerus, femur), Lengths (stature, standing reach height, arm span, midstylion-dactylion , radiale-stylion, tibiale mediale-sphyrion tibiale, midstylion-dactylion) were measured. Also, physiological and Physical Fitness variables: (heart rate, blood pressure, basal metabolic rate (BMR), long jump, barfix, sit up, 20-m sprint, agility 4×9 m, spike jump, block jump, anaerobic power (15s ergojump test), aerobic capacity (2400 m), explosive power (vertical jump), flexibility (sit and reach test)) characteristics were measured. Descriptive statistics are used to describe the subjects profile and Pearson correlation coefficient was used to study relationships between variables. The results showed significant relationships between some variables. Spike jump and block jump were negatively correlated with Height and standing reach height and positively correlated with long jump and flexibility (p<0.05). Also mean values in height and spike and block height were lesser than mean of world’s top adolescent players. The data presented in this paper can be a proper model for coaches in talent identification and competent player selection, finding strengths and weaknesses of Iranian national team comparing to world levels and optimizing planning particularly in training design.
