What is a common response of the body during high-perceived exertion strength training?

During high-perceived exertion strength training, the body typically experiences an increased accumulation of lactic acid. This occurs as a result of anaerobic metabolism, which is heavily utilized during intense exercise when the demand for energy exceeds the availability of oxygen. As muscle activity intensifies, the body breaks down glucose without sufficient oxygen, resulting in the production of lactic acid as a byproduct.

This accumulation can lead to sensations of fatigue or discomfort in the muscles, commonly referred to as "the burn." Understanding this process is crucial for tactical athletes and trainers, as it provides insights into how the body responds to intense training and how to design effective recovery strategies. Managing lactic acid levels can also help athletes optimize their performance during subsequent training sessions or operational demands.
