Marathon performance time in relation to age, physical characteristics, previous running experience, and various training indices of female distance runners

[摘要] The purpose of this study was to determine the correlation between marathonperformance time (MPT) and age, physical characteristics, past running experiences, andvarious training indices. One hundred fifty female distance runners, ages 25 to 50 whohad completed at least one marathon and resided in the states of Wisconsin or Minnesotawerc randomly selected by computer through Media Consultation Services atid theInternational Race Network to participate. Eighty-two percent (N = 123) of thequestionnaires were returned after 6 weeks. Data were analyzed using descriptivestatistics, Pearson product correlations, and stepwise regression analysis. The min permile pace ran at distances of 10 - 15 miles (PI0 - 15; r = .83), min per mile pace from5 - 10 miles (P5 - 10; r = .81), and fastest mile time (FMT; r = .76) correlated highly toMPT. The following prediction equation for MPT (r2 = .77; p <.001) was establishedusing regression analysis: MPT (hr) = 0.346762 (Pl0 - 15) - 0.093685 (T5 - 9)+ 0.1 5369 (FMT) + 0.3 1 167. These findings suggested that 3 training variables willcontribute to improved performance times. The pace when running distances of 10 - 15miles, the number of times per week that distances of 5 - 9 miles are ran (T5 - 9;r = -0.44), and the fastest mile time were the variables most predictive of final MPT.Several recommendations were made for future investigation of training indices related toMPT. These included measurement of the max V02 and on site surveying for a morehomogeneous sample of runners.
