PHYSIOLOGICAL DETERMINANTS OF DISTANCE RUNNING PERFORMANCE ACROSS ADOLESCENT AGE GROUPS (BODY COMPOSITION, MAXIMAL OXYGEN UPTAKE, ECONOMY, ANAEROBIC THRESHOLD, ANAEROBIC CAPACITY)
Abstract
The purpose of this study was to investigate the physiological determinants of distance running performance across adolescent age groups. Subjects for this investigation included 106 highly-active males aged 8 to 21 yr. Based on logistic growth curves, subjects were divided into subgroups aged 8 to 11 yr (n = 23), 12 to 14 yr (n = 29), 15 to 17 yr (n = 29), and 18 to 21 yr (n = 25). Measurements taken included leg strength, anaerobic power, anaerobic capacity (AC), fatigue index (FI), body weight (BW), height, leg length, biacromial diameter (BIAD), bi-iliac diameter, leg volume, relative fat (RF), fat weight, lean body weight, running economy (RE), anaerobic threshold (AnT), maximal oxygen uptake (VO(,2) max), and 2-mi run time. In the overall group of subjects factor analysis of the physiological variables identified three distinct common factors underlying the highly intercorrelated physiological determinants of distance running performance: physical development, body fat, and muscular power. Full-model multiple regression analysis for the prediction of 2-mi run time from the physiological variables resulted in R = 0.92 and SEE = 1.08 min. Of the variables selected in stepwise multiple regression analysis, VO(,2) max accounted for 52% of the variance in 2-mi run time, followed by additional accounted for variance of 20% by BW, 5% by RE, 4% by RF, and 2% by AnT. Across adolescent age groups the significant variables in the model predicting 2-mi run time were RF and RE in the age groups 8 to 11 yr and 12 to 14 yr, RE in the age group 15 to 17 yr, and BW, VO(,2) max, RE, FI, and AnT in the age group 18 to 21 yr. The results indicated that different physiological variables were important to distance running performance at various adolescent stages of growth and development.
