The purpose of this study was to examine the relationships of marathon performance time (MPT) to maximal aerobic power (VO2 max), physical characteristics, and training indices recorded for 12 weeks prior to a race in 35 female distance runners. The marathon experience of the subjects ranged from two to fifteen races. Physical and aerobic power characteristics (mean +/- S.D.) were: age, 35.7 +/- 8.5 yr; height, 166.4 +/- 5.7 cm; weight, 55.1 +/- 5.7 kg; body fat, 15.7 +/- 5.0%; VO2 max, 56.5 +/- 6.2 ml . kg-1 . min-1. Marathon time for this race averaged 227.0 +/- 31.6 min. Records from individual training diaries indicated the runners averaged 71.0 +/- 10.0 workout days, 10.0 +/- 10.0 two X day-1 workouts, 81.0 +/- 8.0 total workouts, 12.3 +/- 1.8 mean km . workout-1, 5402.8 +/- 1302.6 total training min, 187.0 +/- 18.0 m . min-1 training pace, 112.2 +/- 32.1 max km . wk-1, 83.1 +/- 23.4 mean km . wk-1, 998.8 +/- 282.6 km . 12 wk-1 and 13.8 +/- 2.4 mean km . day-1. MPT was positively correlated to body mass index (r = 0.52), and body fat (r = 0.52) but negatively related to VO2 max (r = -0.65). MPT was also negatively related to previous marathons completed (r = -0.47), workout days (r = -0.47), two X day-1 workouts (r = -0.52), total workouts (r = -0.56), mean km . workout-1 (r = -0.58), total training min (r = -0.56), m . min-1, training pace (r = -0.66), max km . wk-1 (r = -0.70), mean km . wk-1 (r = -0.74), km . 12 wk-1 (r = -0.74), and mean km . day-1 (r = -0.77). MPT for our population of runners may be predicted (r = 0.82, R2 = 0.68) by the following equation: MPT, (min) = 449.88 - 7.61 (-/x km.day-1 run) - 0.63 (m.min-1, training pace); SEE = +/- 18.4 min.
本研究旨在探讨35名女性长跑运动员的马拉松成绩时间（MPT）与最大有氧功率（VO2 max）、身体特征以及比赛前12周记录的训练指标之间的关系。受试者的马拉松参赛经历从2次到15次不等。身体和有氧功率特征（均值±标准差）如下：年龄，35.7±8.5岁；身高，166.4±5.7厘米；体重，55.1±5.7千克；体脂，15.7±5.0%；VO2 max，56.5±6.2毫升·千克⁻¹·分钟⁻¹。本次比赛的马拉松时间平均为227.0±31.6分钟。个人训练日记记录显示，跑步者平均有71.0±10.0个训练日，10.0±10.0次两天一次的训练，81.0±8.0次总训练次数，12.3±1.8千米·每次训练，5402.8±1302.6分钟总训练时长，187.0±18.0米·分钟⁻¹训练配速，112.2±32.1千米·每周最大值，83.1±23.4千米·每周平均值，998.8±282.6千米·12周，以及13.8±2.4千米·每天平均值。MPT与体重指数呈正相关（r = 0.52），与体脂呈正相关（r = 0.52），但与VO2 max呈负相关（r = -0.65）。MPT还与之前完成的马拉松次数呈负相关（r = -0.47），与训练日呈负相关（r = -0.47），与两天一次的训练呈负相关（r = -0.52），与总训练次数呈负相关（r = -0.56），与每次训练的平均千米数呈负相关（r = -0.58），与总训练分钟数呈负相关（r = -0.56），与米·分钟⁻¹训练配速呈负相关（r = -0.66），与每周最大千米数呈负相关（r = -0.70），与每周平均千米数呈负相关（r = -0.74），与12周的千米数呈负相关（r = -0.74），以及与每天平均千米数呈负相关（r = -0.77）。对于我们这群跑步者的MPT，可以通过以下方程进行预测（r = 0.82，R² = 0.68）：MPT（分钟）= 449.88 - 7.61（每天跑步的千米数）- 0.63（米·分钟⁻¹，训练配速）；标准误差 = ±18.4分钟。
