Which row correctly identifies the main cause of fatigue for different duration activities?

\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{10 second sprint}\rule[-1ex]{0pt}{0pt}& \textbf{2 minute swim}& \textbf{2 hour run} \\
\hline
\rule{0pt}{2.5ex}\text{ATP depletion}\rule[-1ex]{0pt}{0pt}&\text{Lactic acid}&\text{Glycogen depletion}\\
\hline
\rule{0pt}{2.5ex}\text{Lactic acid}\rule[-1ex]{0pt}{0pt}& \text{Glycogen depletion}&\text{ATP depletion}\\
\hline
\rule{0pt}{2.5ex}\text{Glycogen depletion}\rule[-1ex]{0pt}{0pt}& \text{ATP depletion}&\text{Lactic acid} \\
\hline
\rule{0pt}{2.5ex}\text{Lactic acid}\rule[-1ex]{0pt}{0pt}& \text{ATP depletion}&\text{Glycogen depletion} \\
\hline
\end{array}
\end{align*}

\(A\)

Show Worked Solution
  • A is correct: A is correct: ATP depletion occurs <10s, lactic acid peaks at 1-2 min, glycogen depletes after 90+ min

Other Options:

  • B is incorrect: Lactic acid doesn’t cause fatigue at 10s; glycogen doesn’t deplete at 2 min
  • C is incorrect: Completely reverses the correct fatigue mechanisms
  • D is incorrect: Lactic acid doesn’t occur at 10s; ATP doesn’t deplete at 2 min
