Final answer:
The glycolytic (anaerobic) system provides relief by producing energy for short bursts of high-intensity exercise, leading to the accumulation of lactic acid and subsequent muscle fatigue.
Step-by-step explanation:
The glycolytic (anaerobic) system develops relief in the form of short bursts of high-intensity energy output. During anaerobic exercise, such as sprinting or lifting heavy weights, muscles perform work without using oxygen. This process involves glycolysis, where glucose is broken down to produce small amounts of adenosine triphosphate (ATP), which is vital for cellular reactions. However, since the process leads to the accumulation of lactic acid, it results in the sensation of muscle fatigue and the need for a recovery period, referred to as oxygen debt. It is particularly relevant for activities lasting between 1.3 to 1.6 minutes, like the 100 meter swim or the 200 m to 400 m run.
