Front

As exercise intensity increases, the % of ATP from fat _____________.

Back

DECREASES

Front

The energy for the function of your metabolism is provided by the _____________.

Back

foods you eat

Front

What factors affect running economy?

Back

All of the above (Shoe Weight, Body Weight, Technique/Form)

Front

Which of the following is considered the gold standard measure of cardiorespiratory/aerobic fitness?

Back

directly measured maximal oxygen uptake (VO2max)

Front

The lactate threshold describes:

Back

the level of exercise intensity where lactate begins to accumulate in the blood

Front

Define metabolic rate.

Back

The rate at which the body expends energy or burns calories.

Front

What is VO2max?

Back

The maximum amount of oxygen the body can utilize during intense exercise.

Front

Explain the relationship between exercise intensity and energy source utilization.

Back

As exercise intensity increases, the body shifts from using fat as a primary energy source to carbohydrates.

Front

What is the significance of the lactate threshold in exercise performance?

Back

It indicates the exercise intensity at which lactate starts to accumulate, affecting endurance performance.

Front

How does body weight influence running economy?

Back

Higher body weight can increase energy expenditure and decrease running efficiency.
