You are calculating an exercise intensity for a client with a VO2 max of 53.5 ml · kg · min-1. If he wanted to work at 65% of his VO2 max, what level of intensity, in ml · kg · min-1, would you suggest for him?

a. 30

b. 35

c. 43

d. 48

In general, when working with sedentary people to help them become active, a reasonable rate of progression (in terms of the number of additional minutes done per week) would be to increase time by about

a. 10%

b. 15%

c. 20%

d. 25%

One of your clients is 6 feet 3 inches (190.5 cm) tall and weighs 240 lb (109 kg). According to these values, his BMI is

a. 35.3 kg · m-2

b. 30.3 kg · m-2

c. 27.3 kg · m-2

d. 24.3 kg · m-2

After a 15-week endurance training program, the most likely effect of training on blood pressure (BP) would be:

a. an increased systolic pressure at maximal workloads

b. an increased diastolic pressure at maximal workloads

c. a decreased systolic pressure at submaximal workloads

d. no change in systolic pressure at submaximal workloads

After a 15-week endurance training program, which of the following responses would you expect to see (compared with pre-training) regarding stroke volume (SV)?

a. higher SV at submaximal workloads

b. lower SV at submaximal workloads

c. lower SV at maximal workloads

d. no change in SV at submaximal workloads

After a 15-week endurance training program, which of the following responses would you expect to see (compared with pre-training) regarding cardiac output?

a. higher cardiac output at maximal workloads

b. unchanged cardiac output at maximal workloads

c. lower cardiac output at submaximal workloads

d. unchanged cardiac output at submaximal workloads

e. a and d

Solution

You are calculating an exercise intensity for a client with a VO2 max of 53.5 ml · kg · min-1. If he wanted to work at 65% of his VO2 max, what level of intensity, in ml · kg · min-1, would you suggest for him?

a. 35

65% of his VO2 max=65% of 53.5 ml · kg · min-1 =34.775 or apprx. 35

In general, when working with sedentary people to help them become active, a reasonable rate of progression (in terms of the number of additional minutes done per week) would be to increase time by about

b. 15%

One of your clients is 6 feet 3 inches (190.5 cm) tall and weighs 240 lb (109 kg). According to these values, his BMI is

b. 30.3 kg · m-2

Bodyweight in kilograms divided by height in meters squared
           or
BMI = x KG / (y M * y M)

where x=bodyweight in kg
y=height in m

height=190.5cm=1.905m

So BMI=190kg/ (1.905 *1.905)=190/3.62905=30.3kgm^-2
