During which phase of periodization would an athlete likely perform sets with 85% of their one-repetition max?

The strength phase of periodization focuses on increasing muscular strength and is characterized by the use of heavier weights and lower repetitions. When an athlete performs sets at 85% of their one-repetition maximum (1RM), they are likely working within a rep range that optimally stimulates the neuromuscular system and promotes strength gains. This percentage is typically associated with a lower number of repetitions, which aligns with the goals of this phase.

In this phase, the emphasis is on building maximal strength, which requires training at a significant intensity. Training at 85% of 1RM enables the athlete to recruit a high percentage of muscle fibers, leading to greater adaptation and strength improvements. By contrast, other phases such as the general preparation phase focus on building a foundation that may include higher repetitions with lighter weights, while the peaking phase often includes specific adjustments to maximize performance just before competition, where the percentages might vary based on the athlete's goals and tapering strategy. The endurance phase, conversely, would involve much lower percentages of 1RM and aim at enhancing muscular endurance rather than maximal strength.
