A sprinter is working to improve their block start performance. Which biomechanical sequence would most effectively generate maximal horizontal force from the blocks?

\begin{align*}
\begin{array}{l}
\rule{0pt}{2.5ex} \ \rule[-1ex]{0pt}{0pt}& \\
\rule{0pt}{2.5ex}\textbf{A.}\rule[-1ex]{0pt}{0pt}\\
\rule{0pt}{2.5ex}\textbf{B.}\rule[-1ex]{0pt}{0pt}\\
\rule{0pt}{2.5ex}\textbf{C.}\rule[-1ex]{0pt}{0pt}\\
\rule{0pt}{2.5ex}\textbf{D.}\rule[-1ex]{0pt}{0pt}\\
\end{array}
\begin{array}{|l|l|l|}
\hline
\rule{0pt}{2.5ex}\textbf{Rear Leg Action}\rule[-1ex]{0pt}{0pt}& \textbf{Front Leg Action}& \textbf{Trunk Position} \\
\hline
\rule{0pt}{2.5ex}\text{Concentric hip extension}\rule[-1ex]{0pt}{0pt}&\text{Isometric knee extension}&\text{Forward lean 45°}\\
\hline
\rule{0pt}{2.5ex}\text{Eccentric knee extension}\rule[-1ex]{0pt}{0pt}& \text{Concentric hip extension}&\text{Forward lean 30°}\\

\end{array}
