010-111 · Question #287

As the percentage of 1 RM (Repetition Maximum) resistance increases ______.

The correct answer is C. the number of repetitions until fatigue decreases. There is a well-established inverse relationship between percentage of 1RM and the number of repetitions achievable before fatigue. Higher loads cause more rapid neuromuscular and metabolic fatigue, reducing repetition capacity.

Why each option

There is a well-established inverse relationship between percentage of 1RM and the number of repetitions achievable before fatigue. Higher loads cause more rapid neuromuscular and metabolic fatigue, reducing repetition capacity.

Athe amount of rest between training days should increase

Rest between training days is governed by overall training volume and recovery demands, not solely by the percentage of 1RM used in a given session.

Bthe number of sets performed should increase

The number of sets is an independent programming variable that does not automatically increase as 1RM percentage rises; sets may actually decrease at very high intensities.

Cthe number of repetitions until fatigue decreasesCorrect

As the percentage of 1RM increases, greater motor unit recruitment and faster phosphocreatine depletion occur, leading to earlier fatigue onset and a reduced number of repetitions that can be completed. This inverse load-to-repetition relationship is a foundational principle of resistance training, with loads near 100% 1RM typically permitting only 1-3 repetitions before failure.

Dthe amount of rest between sets should decrease

Higher 1RM percentages require longer inter-set rest periods, not shorter ones, because greater neuromuscular fatigue and energy system depletion demand more recovery time.
