Which of the following best describes the symptoms of muscle fatigue?

Muscle fatigue is characterized by a decline in muscle strength and efficiency, which is directly related to a combination of biochemical and physiological factors that occur during prolonged or intense physical activity. As muscles undergo repeated contractions, they may experience a depletion of energy stores, accumulation of metabolic byproducts like lactic acid, and impairment of nerve signal transmission. This results in a noticeable loss of control over muscle movements, as the muscles cannot generate the same level of force or perform efficiently. Consequently, the feeling of weakness and the inability to sustain vigorous activity or maintain the same level of performance are key symptoms of muscle fatigue.
