How long does the Wingate test last?
30 seconds
What is the pedal rate for all the submax cycle tests?
50 rpm
Where does the electrode V4 go on a person's body?
In line straight down from Left Arm, in the 5th intercostal space (below muscle or breast tissue).
If someone's 15-second heart beat count during exercise is 30, what is their heart rate?
120
At rest, are we burning more carbs or fats?
Fats.
How hard should someone pedal during a Wingate test?
As hard as they can for the whole time.
What fact about intensity and heart rate and VO2 usage do we rely upon to estimate VO2 max from a submax test?
That they all have a positive LINEAR relationship.
As one goes up, the others go up.
To measure knee flexion, where do the axis, stationary arm, and mobile arm of the goniometry line up?
axis - on the lateral epicondyle (the bump on outside of knee that doesn't move during flexion)
stationary arm - from axis to greater trochanter (hip joint)
mobile arm - from axis to lateral malleolus (bump on outside of ankle)
What is a categorically 'healthy' blood pressure?
<80
What structure carries an action potential into and throughout a muscle cell?
T-tubules
What is being measured by the Wingate test?
anaerobic power
Give the wordful definition of what VO2max is.
The maximal amount of oxygen someone can transport and consume.
On an ECG, if there are 3 big boxes between R waves (heart beats), what is the person's heart rate?
100bpm
What is the term for a heart rate that is faster than 100 bpm?
Tachycardia
What ion causes an action potential to carry on down a nerve?
How much weight is added to the weight platform for someone during Wingate?
body weight in kg x 0.075
Name 2 of the 4 qualifiers of a TRUE MAX test.
- O2 plateaus
- RER > 1.1
- lactate > 8mmol
- max HR reached
If there are 7 R waves (heart beats) in a 30 box interval on an ECG, what is the person's heart rate?
70bpm
5 boxes = 1 second, therfore
30 boxes = 6 seconds,
there are 10 six-second intervals in a minute, so
7 x 10 = 70bpm
Where and in what direction do you pinch for the subscapular skinfold site?
2 cm below the scapula, diagonal
As exercise intensity goes up, RER goes up or down?
Up.
Higher intensities use more carbs, therefore RER will be higher.
What energy system is being measured for PEAK power?
ATP-PC
If someone's heart rate during the last two minutes of the Astrand submax test are 115 and 122, do they need to continue for the 7th minute or stop now?
Continue to 7th minute.
The last two minutes should be in steady state, which means within 5 bpm of each other, and 115-122 is 7, so not steady state yet.
What is active insufficiency?
When a muscle is flexed over two joints, it isn't able to contract with full force over either of those joints.
What percentage of body fat is essential for females? For males?
12% - females
3% - males
What causes myosin to be able to attach to actin during a muscle contraction?
Calcium attaches to troponin which transforms causing tropomyosin to uncover the binding sites on actin.
