Final answer:
Sub-maximal training loads are performed when an athlete wants to train at a lower intensity to allow for recovery or work on technical aspects without overloading the body.
Step-by-step explanation:
Sub-maximal training loads are usually performed when an athlete wants to train at a lower intensity level to allow for recovery or to work on specific technical aspects without overloading the body.
One example is using sub-maximal training loads during a deload week, which is a period of reduced training intensity and volume to facilitate recovery. During this time, athletes perform workouts at a lower percentage of their maximum capacity to give their bodies a chance to heal and adapt.
Another example is when an athlete wants to refine their technique. By using sub-maximal loads, they can focus on executing the movements correctly and ingraining proper form without sacrificing performance.
