Fig 1.
Example of resultant force curves of the front and rear blocks during a sprint start recorded by the instrumented starting blocks.
RT, reaction time; RBT, rear block time; FBT, front block time; TBT, total block time; RPF, rear peak force; FPF, front peak force.

Table 1.
Characteristics of the participants in the whole sample and the three Cormic Index groups.
Data are means ± SD.
Table 2.
Block distances, and kinematic and kinetic data in the sprint start for the whole sample as well as for the three Cormic Index groups in their usual block setting condition (US) and an anthropometry-driven block setting (AS) condition.
Data are means ± SD.
Table 3.
Results of the mixed-design ANOVA to quantify the effect of condition and effect of group by condition interaction on block distances, and kinematic and kinetic data.
Table 4.
Multiple linear regression model estimated using the difference (Delta) in the anteroposterior block distances between the two conditions (US and AS) as predictors and the delta in the performance variable as the dependent variable.
