1)All of the following are 2 component models EXCEPT...

	A.	Hydrostatic weighing (underwater weighing)
	B.	Skinfold thickness
	C.	Air-displacement plethysmography (bod-pod)
	D.	Dual-energy x-ray absorptiometry (DEXA)

2)Which method of densitometry utilizes Archimedes' principle to determine body density?

	A.	Skinfold thickness
	B.	Bioelectrical Impedance Analysis (BIA)
	C.	Air-displacement plethysmography (bod-pod)
	D.	Hydrostatic weighing (underwater weighing)

3)

Which of the following could best (most accurately) measure vertical power output?

	A.	Jump test using a wall
	B.	Jump test on a force plate
	C.	Jump test using a Vertec
	D.	Jump test on a switch mat

The next day at your facility, a sprinter comes in and wants to test their anaerobic power. You are going to be sport specific, so you do a sprint test rather than a WAnT. The sprinter is 177cm tall and 72kg. The athlete’s resting HR is 58BPM, and resting blood pressure is 118/76. The sprinter runs at top speed over 100m. The athlete completes the distance in 14 seconds.

You want to calculate the average horizontal power (in kgm/s) for the 100m. This requires the mass moved to be multiplied by the speed at which it was moving. What would be this athlete's horizontal power?

	A.	~557kgm/s
	B.	~514kgm/s
	C.	~613kgm/s
	D.	~479kgm/s

5)

Use the information from questions 61-64. Power output for the wingate test can be calculated by multiplying the kg resistance x 9.80665 x number of revolutions x distance of the flywheel (typically 6m) ÷ the duration of cycling. This can be difficult, so algebraically, this could be reduced to kg x rpm x 58.8399 ÷ the duration of cycling. If you were to measure power output for 5 seconds, where the cyclist performed 11 revolutions, what would the power output be over this period? (hint: 58.8399 ÷ 5 = 11.768)

	A.	~789W
	B.	~737W
	C.	~854W
	D.	~822W
