Question

Charlie is easily winded during soccer practice and wants to improve his cardiorespiratory fitness. Which activity would be best for him to choose?

aLifting weights  bWalking from one class to another

 cRunning in a 5K race  dRiding a bike at a leisurely pace

Answer 1

I believe the answer is C.  Walking from class will not help your cardio respiratory system.  Neither would riding a bike at leisure pace, that does nothing for you.  And lifting weights helps with your muscle growth, not your cardio endurance.  Hope this is helpful!

Answer 2

The answer is: c. Running in a 5K race

All exercises that improve your heart rate for an extended period of time will improve your respiratory fitness. This means that walking, running, and riding bikes would all improve our cardio respiratory fitness in a certain way.

But, running on a 5k race is the most suitable for soccer Athlete like Charlie because the intensity of running in 5k race and soccer match is really similar. Walking and biking at leisurely pace do not provide the intensity needed for soccer athlete's conditioning.
