Consider the causes of muscle fatigue. Then click and drag each label into the appropriate category based on whether it is a cause of fatigue from predominantly high-intensity short duration exercise, low-intensity long duration exercise, or neither. Decrease in sarcoplasm pH. Electrolyte loss. Decrease in hydrolysis of ATP due to accumulation of ADP and phosphate. Increased oxygen levels in the sarcoplasm. ATP depletion. Lactic acid inhibition of cross-bridge formation. Hypoglycemia. Decrease in potassium ion concentration in the sarcoplasm. Decrease in stored glucose. Decrease in nerve impulses from the CNS. High-Intensity Low Duration. Low-Intensity High Duration. Neither.

29. During high intensity, short-duration exercise (weight lifting, for example), fatigue is believed to be partially caused by: The decrease in extracellular Calcium caused by sweating_ The increase in extracellular Potassium and increase in intracellular ADP caused by the activity of the muscle fibers. The decrease in localized temperature that occurs in active muscle fibers. D The decrease in intracellular Sodium caused by the Action Potential_
