What percentage of a one-repetition maximum (1RM) is typically associated with maximum power output?

The range of 55% to 85% of a one-repetition maximum (1RM) is indeed associated with maximum power output. This percentage strikes a balance between sufficient load and the ability to perform exercises explosively. When lifting at this intensity, the muscle fibers are activated effectively, promoting both the recruitment of fast-twitch muscle fibers and the development of maximal power.

At lower percentages, such as below 55%, while the speed of lifting may be higher, the load is insufficient to stimulate significant power development. Conversely, at higher percentages (above 85%), the focus shifts more towards strength rather than power, as the lift becomes slower and more controlled, which isn’t optimal for generating maximum power output. Therefore, training within the 55% to 85% range allows for an effective combination of weight and speed, crucial for power development in athletes and fitness enthusiasts.
