In NASM OPT Phase 5, explosive speed drops as the client fatigues within a set. What is the appropriate adjustment?
- ALower the load and finish the remaining reps at a slower, controlled tempo
- BComplete the planned reps while cueing a tall, braced posture
- CExtend rest or stop the set when speed drops
- DShorten rest to build fatigue resistance
Show answer and explanations
Answer
C
When explosive speed falls, power quality is being lost; the trainer should restore recovery or stop the set so the remaining reps stay fast and controlled.
A
A slower tempo gives up the explosive intent that defines Phase 5; the problem is fatigue, not technique at this load.
B
Posture cues do not restore speed; finishing reps as velocity falls accumulates fatigue and trains slow force rather than power.
D
Shorter rest adds fatigue; that suits endurance work but further reduces explosive output.
