Prediction of half-marathon race time in recreational female and male runners The half marathon track enjoys great popularity. In earlier work, we tried a formula to develop runners based on simple parameters to estimate the expected conclusion.This gave himself that the running speed in training for men like women is important.For women, the skin folds were added in the armpit and in the men of the BMI. In an evaluation with a larger number of cases showed that body fat and running speed in training for both men as well as for women the best variables are correlated with the half marathon time.We have now looked if we improve the existing formulas resp.can simplify.
Now the final time for men on the basis of formula 142.7 + 1,158 x body fat (%) - 5.223 x running speed in training (km / h) and for women based on the formula 168.7 + 1.077 x body fat (%) - 7,556 running speed in training (km/ h) be estimated.
