峰值有氧功率（V.O2peak）和训练相关参数与优秀运动员长跑成绩相关。跑步经济（RE）预测年轻运动员的表现，但其与老年运动员比赛能力的关系尚不清楚。异速生长标度的RE（alloV.O2; ml kg −0.66 min−1）、能量成本（EC; kcal kg−1 km−1）和次最大回合所需的V.O2峰值百分比（% V.O2peak）比V.O2更准确地表示RE。VDOT评分估计V. O2峰值和RE，可用于比较不同距离的比赛。确定长跑运动员（10-26.2英里）训练中温度转换VDOT的预测因素。23名跑步大师（年龄57±9岁，8名女性）在目标比赛的四周内进行了跑台马拉松强度努力（MIE）和V. O 2峰值测试。MIE发生在预测最大心率的88%，这对应于估计的马拉松强度。参与者完成了在线培训历史调查。采用前向逐步多元线性回归寻找VDOT的关键预测因素。显著性的α水平为0.05。转换后的VDOT与三年峰值每周训练距离（3 YP）（r = 0.454，p = .039）、V. O2峰值（r = 0.845，p = .000）、alloV. O2（r = 0.623，p = .005）和EC（r =-0.528，p = .018）显着相关。最佳拟合模型为V.O2peak和3 YP（r = 0.898）。优秀运动员的比赛成绩与生理和训练因素有关。VDOT的最佳预测因子是V. O2 peak和3 YP。训练，以提高这些变量可能会提高长跑成绩的主人。
Peak aerobic power (V .O2peak) and parameters related to training are associated with long-distance running performance in master athletes. Running economy (RE) predicts performance in younger runners, but its relationship to racing ability in older athletes is unclear. Allometrically scaled RE (alloV .O2; ml kg −0.66 min−1), energy cost (EC; kcal kg−1 km−1), and percent of V .O2peak (%V .O2peak) required in a submaximal bout represent RE more accurately than V .O2 does. The VDOT score, estimating V .O2peak and RE, can be used to compare races of different distances. To determine predictors of temperature-converted VDOT in master runners training for a long-distance race (10-26.2 mi). Twenty-three master runners (age 57±9 years; eight females) performed treadmill marathon-intensity-effort (MIE) and V .O2peak tests within four weeks of their goal race. The MIE occurred at 88% of predicted maximum heart rate, which corresponds to estimated marathon intensity. Participants completed online training-history surveys. Forward stepwise multiple linear regression was used to find key predictors of VDOT. The alpha level for significance was .05. Converted VDOT was significantly associated with three-year peak weekly training distance (3YP) (r = 0.454, p = .039), V .O2peak (r = 0.845, p = .000), alloV .O2 (r = 0.623, p = .005), and EC (r = −0.528, p = .018). The best-fitting model included V .O2peak and 3YP (r = 0.898). Physiological and training factors are related to race performance in master runners. The best predictors of VDOT are V .O2peak and 3YP. Training to enhance these variables may improve distance-running performance in masters.
