Cardiorespiratory Fitness Testing

These flashcards cover key concepts and definitions related to cardiorespiratory fitness testing, including specific measures, assessments, and test protocols.

What is defined as the ability to perform dynamic exercise involving large muscle groups at moderate to high intensity for prolonged periods?

Cardiorespiratory endurance.

What does VO2max represent in the context of exercise?

The maximum rate of oxygen uptake during maximal exercise; it is the gold standard measure of cardiorespiratory fitness.

How is absolute oxygen consumption expressed?

In liters per minute (L/min).

How does relative oxygen consumption differ from absolute oxygen consumption?

Relative oxygen consumption is expressed in mL/kg/min and allows for comparison of cardiorespiratory fitness independent of body size.

What is the significance of a 1 MET increase in aerobic capacity?

It is associated with a 12% improvement in survival.

Why is it important to assess cardiorespiratory function during exercise?

Resting assessments may not reveal issues; exercise testing can screen for cardiovascular disease (CVD) effectively.

What is the role of open-circuit spirometry in fitness testing?

It measures gas exchange during graded exercise tests (GXT) to evaluate aerobic capacity.

What are some common field tests for assessing cardiorespiratory fitness?

Walking, running, treadmill tests, cycle ergometer tests, and step tests.

What do submaximal testing assumptions include?

Assumptions about steady-state heart rate, uniform maximal heart rates, and the linear relationship between heart rate and VO2max.

What is the formula used to calculate VO2max in the Rockport 1 Mile walk test?

VO2max = 132.853 - 0.0769(weight) - 0.3877(age) + 6.315(gender) - 3.2649(time) - 0.1565(HR).

What is a significant advantage of treadmill tests compared to other testing methods?

They are reproducible and can accommodate any fitness level.

In assessing the accuracy of fitness tests, how does submaximal testing vary from maximal testing?

Maximal tests are more accurate but involve more risk; submaximal tests are less accurate but safer and easier to manage.

What physiological criteria indicate that a person has reached VO2max?

1. Plateau in VO2, 2. Blood lactate reaches 8 mM, 3. RER > 1.1, 4. Reached 90% of age-predicted maximum heart rate.

What does the RPE scale measure?

It measures the Rate of Perceived Exertion during physical activity, helping to gauge exercise intensity.
