Question

6.) A male, 34 year old participant is 5’5” and weighs 68 kg. They completed a step test with the following parameters:

Step height: 16 inches

Step rate: 30 steps/min

Duration: 5 mins

1. What is this person’s gross VO2? How would you classify their CRF? (3 points)

2. What is this person’s oxygen cost in METs? (1 point)

7.) Your participant is 5’8” and weighs 178 lbs. They completed an exercise bout using arm ergometry with the following parameters:

Flywheel: 2.4 m/rev

Pedal rate: 50 rpm

Work load: 2.0 kp

Duration: 5 mins

1. What is this person’s gross VO2? (2 points)

2. What is this person’s oxygen cost in METs? (1 point)

OPTIONAL EXTRA CREDIT:

You have a client perform the Balke walking test. Using the Balke equation AND the ACSM walking equation, calculate and classify their VO2. Which VO2 do you think is more accurate and why? (4 points)

Male

22 years old

Time on treadmill: 15:23

Classification: ____________

Answer 1

ANSWER 1.

VO₂ = (0.35 × f) + (2.395 × f × h)

VO₂ = (0.35 x 30) + (2.395 x 30 x 0.4064)

VO₂ = 10.5 + 29.20

VO₂ = 40 ml/kg/min

for a 34 yr old man with VO2 is classified as a "good" CRF score.

ANSWER 2. CLASSIFICATION:

for men, Cardiorespiratory Fitness Chart based on maximum oxygen consumption

Age	Very Low	Low	Fair	Good	Excelle
20-29	< 25	25-33	34-42	43-52	≥ 53
30-39	< 23	23-30	31-38	39-48	≥ 49
40-49	< 20	20-26	27-35	36-44	≥ 45
50-59	< 18	18-24	25-33	34-42	≥ 43
60-69	< 16	16-22	23-30	31-40	≥ 41

ANSWER 3. MET CALCULATION

.MET= VO2 3.5ml/kg

MET= 40 3.5= 11 ml
