SFP124 HE WK23 Cardiorespiratory Fitness

Multiple Choice

What does Cardiorespiratory Fitness (CRF) refer to?

• The ability of the circulatory and respiratory systems to supply oxygen to muscles during sustained physical activity

• The strength and endurance of skeletal muscles during physical activity

• The flexibility of joints and the range of motion during physical activity

• The speed and agility of an individual during short bursts of intense physical activity

Multiple Choice

What is the gold standard for measuring CRF?

• VO2max testing

• Heart rate monitoring

• Blood pressure measurement

• Body mass index (BMI)

Multiple Choice

What does VO2max measure?

• The maximum amount of oxygen a person can utilize during intense exercise

• The minimum amount of oxygen a person can utilize during rest

• The average amount of oxygen a person can utilize during moderate exercise

• The total amount of oxygen a person can utilize in a day

Multiple Choice

One of the main purposes of warming up prior to performing cardiorespiratory training is to:

• Prevent venous pooling (accumulation of blood in the veins)

• Develop and maintain cardiorespiratory fitness

• Increase muscle temperature and blood flow to lower the risk of injury

• Assist in the breakdown and removal of metabolic by products

Multiple Choice

As part of her training for the 400 m event, an elite athlete completes 4 × 250 m sprints in 30 seconds, with 60 seconds rest between each sprint. At the completion of her training session, the athlete should perform a cool-down in order to:

• Prevent venous pooling (accumulation of blood in the veins)

• Assist in the breakdown and removal of metabolic by products

• Keep the heart rate elevated to assist oxygen delivery to skeletal muscles

• All of the above

Open Ended

In the following training scenario, suggest ways in which an athlete could introduce overload:

An 800-metre elite runner: one set of 6 × 300-metre intervals run at 75 per cent MHR with 1-minute walk recoveries between efforts.
