What is maximal velocity decay and how can training help mitigate it?

• A. An improvement in speed with fatigue.
• B. Constant speed regardless of fatigue.
• C. An increase in maximal velocity with training.
• D. The decline in speed due to fatigue during repeated sprints; mitigated with speed endurance work, adequate recovery, and technique maintenance under fatigue.

Answer: (D)

Maximal velocity decay is the drop in top sprint speed that happens as fatigue builds during repeated sprints. When you run several short sprints with limited rest, energy stores are depleted, metabolic byproducts accumulate, and neuromuscular efficiency falls, all of which slow you down at your maximum velocity. Training to reduce this decay focuses on developing repeated-sprint ability through speed endurance work, which teaches you to maintain high speeds under fatigue; ensuring adequate recovery so energy systems can reset and metabolites clear between efforts; and practicing technique under fatigue so mechanics stay efficient even when tired (avoiding excessive braking, overstriding, or loss of posture). This combination directly targets the inability to sustain peak speed across repeated efforts, making it the best description of how to mitigate maximal velocity decay.
