Athletic performance is a complex multifactorial phenomenon, therefore several variables should be considered to provide an accurate prediction of time in races. However, physiological variables have usually been used as the main predictors, ignoring the predictive potential of other factors such as psychological variables. The main aim of this study was to provide an equation for predicting performance at 10K, using both physiological and psychological factors as explanatory variables. 13 male runners participated in the study (weight 68.06 ± 18.73 kg; height 174.31 ± 5.39 cm; age 39.5 ± 8.5 years; 57.34 ± 5.03 ml - kg -min VO2MAX). A multiple regression model was established using a stepwise regression approach based on Ordinary Least Squares (OLS). After check possible collinearities, results showed as better predictors of the time at 10K event: VVO2MAX (β=-1.03), Arousal (β=0.17) and Isolation (β=0.19). The resulting regression showed a coefficient of determination (R2) of 0.98 and RMSE= 50.30 s. VVO2MAX was the best predictor of the 10K performance. However, psychological factors, such as Arousal and Isolation, explain the addition variance. A higher VVO2MAX, a lower Arousal and a higher Isolation might allow better athletic performance in the 10K race.
