Question

The major factor that contributes to an age-related decline in endurance performance is:

a. a decline in VO2 max
b. All of these factors contribute equally to the age-related decline in performance
c. a decrease in the lactate threshold
d. a decline in exercise economy

Answer 1

The major factor that contributes to an age-related decline in endurance performance is a decline in exercise economy. Aging leads to a loss of muscle mass and strength, resulting in a reduced ability to produce powerful contractions. This decline in muscle mass causes a loss of endurance and stamina, particularly in activities that require strength and powerful movements.

Step-by-step explanation:

The major factor that contributes to an age-related decline in endurance performance is a decline in exercise economy. Aging leads to a loss of muscle mass and strength, resulting in a reduced ability to produce powerful contractions. This decline in muscle mass causes a loss of endurance and stamina, particularly in activities that require strength and powerful movements.
