Harvard step test
Cooper test
Yo-Yo intermittent recovery test
Beep test
Which of the following best describes the relationship between Vo2max and cardiorespiratory fitness?

Higher Vo2max indicates higher cardiorespiratory fitness
Vo2max is unrelated to cardiorespiratory fitness
Vo2max only measures muscular strength
Which of the following is a limitation of submaximal Vo2max testing?

Which equation is commonly used to estimate Vo2max from the Cooper 12-minute run test?
Vo2max=0.1distance(miles)−0.5
Vo2max=(distance in miles×35.97)−11.29
Vo2max=(distance in miles×35.97)+3.5

Which of the following is a benefit of improving cardiorespiratory fitness?
Increased risk of heart disease
Improved oxygen delivery to muscles
Decreased lung capacity
Reduced metabolic rate
Which of the following best describes the glycolytic energy system?
Uses oxygen to produce ATP
Produces ATP quickly without oxygen, resulting in lactic acid
Relies on fatty acids for energy
Is only active during rest
