1
Q

How to calculate lean body mass?

A

Measured in lbs or kg

THIS IS FAT MASS
(130 lbs (weight) x 12% (body fat percentage) = 15.6 lbs of fat mass)

THIS IS LEAN BODY MASS
130 (Weight) - 15.6 (answer above) = 114.4 lbs of lean body mass

Q

Hypovolemia

A

Severe Dehydration
low plasma volume (results in a higher RBC count than plasma)

26
Q

Anaerobic Glycolysis

A
  • High intensity for 7-12 seconds.
  • Repeated high intensity efforts when there is insufficient time to recover PC stores and glucose and/or lactate are now used for energy
27
Q

Aerobic Glycolysis

A
  • Low to submaximal effort for 30 seconds or more.
28
Q

Blood Pressure Assessment Procedures

A
  1. Patient sits for ~2 mins w/ feet flat, legs uncrossed, & arms at heart level
  2. Wrap cuff on upper arm, 1 inch above antecubital space
  3. Place bell of stethoscope over the brachial artery
  4. Inflate cuff to around 180-200 mmHg, depending on population
  5. Slowly release pressure at 2-4 mmHg per second
  6. SBP = point at which the first of two or more Korotkoff sounds is heard(phase 1)
  7. DBP = point before disappearance of Korotkoff Sounds (phase 5)
29
Q

New Guidelines for Blood Pressure Categories

A

-Normal : Less than 120 and less than 80
-Elevated: 120-129 and less than 80
-High Blood Pressure stage 1: 130-139 or 80-89
- High blood pressure stage 2: 140 or higher or 90 or higher
- Hypertensive crisis: Higher than 180 and/or Higher than 120

30
Q

Explanation of protocol for Manual Wingate Test

A

1) Warm-up (5-min)
1. Include two 15 sec sprints
2. Test (30sec)
3. Cool Down (5 to 10 min)

31
Q

𝑉O2

A

The ability of the pulmonary, cardiovascular, and muscular systems to absorb, transport and utilize oxygen

32
Q

absolute 𝑉O2

A

L/min total amount of oxegen you breathe in

33
Q

relative 𝑉O2 ask lindsey

A

mL/kg/min amount of oxegen you enhale relative to your weight

34
Q

sub-maximal test,

A

The testing protocol is performed at a low enough intensity, so the subject does not reach failure during the assessment

35
Q

𝑉CO2

A

Volume of CO2

VCO2/VO2

and RER

36
Q

RER

A

respiratory exchange ratio
Ratio between amount of CO2 produced and O2 consumed in one breath

1.1 RER ask lindsey

37
Q

Physiological rationale for 𝑉O2 max testing. Clinical Setting? Performance Setting?

A

Clinical Setting:
1. Prescribe work rates
2. Monitor the client to make sure they are getting better

Performance Settings:
1. Prescribe work rates in athletic setting
2. Monitor to make sure they are getting better

38
Q

𝑉O2 max and work rate

A

higher work rate the higher your VO2 max

39
Q

𝑉O2 and heart rate

A

closer to VO2 max closer to heart rate max

40
Q

𝑉O2 and RER

A

as VO2 max increases RER increases

measurement of CO2/O2

41
Q

Running a 𝑉O2 max test from start to finish using any protocol

A

Bruce protocol

Warm up 3-5 min

Test: 3 min
Speed and grade increase with each stage

42
Q

electrode placement for chest leads

A

V1= 4th intercostal space to right of sternum
V2= 4th intercostal space to left of sternum
V3= Midway between V2 and V4
V4= 5th intercostal space at left mid-clavicular line
V5= Left anterior axillary line at level of V4
V6= Left mid-ancillary line at level of V4 and V5

43
Q

lactate

A

Anaerobic metabolism is turning on

Lactate is fuel source for brain and heart

Lactate threshold 2.0 I think

Glucose to 2 pyruvate to lactate or acetochol A

44
Q

Does a higher or lower lactate threshold indicate enhanced performance

A

Higher

45
Q

Erythropoietin

A

increases red blood cells and hemoglobin production

46
Q

blood composition

A

1) Red blood cells ( erythrocytes)
2) White blood cells (leucocytes)
3) Platelets ( Thrombocytes)

47
Q

Effects of severe dehydration

A
  • reduces ICF and ECF
  • Thermoregulation can get messed up
  • Blood flow can be affected
48
Q

Factors that affect VO2

A

Hereditary
Sex
Age 15 through 18
Training status
Mode of exercise

49
Q

ECG spreadsheet form 8 or 9 points

a vo2

absolute

relative

catagory know what to circle

A
50
Q

VO2 max vs. VO2 peak

was this a vo2 max or a peak

A

4 Criteria

meet at least 2 out of 4 it is a VO2 MAX IF not it is a PEAK TEST

1.) Did they get within 10bpm of HR max 220 - age = HR MAX

2.)RER anything above 1.10 is a criteria

3.) RPE + 8.5

4.) Plateau of VO2 despite an increase in work rate

look for the highest value

51
Q

LACTATE THRESHOLD

A

RIGHT BEFORE it shoots up many units not 0.1 more than that

52
Q

lactate

A

anaerobic metabolism

turning it on

less blood flow to liver and kidneys and lactate tissues

53
Q

Resting Blood Lactate is around 0.5- 2.0 Note when finding lactate threshold

A
54
Q

same individual that becomes more fit

the deflection or lactate threshold will come later in a graded exercise testing

BOTH TEST

A
55
Q

Physiological rationale for lactate threshold ASK LINDSEY

A

indications of anaerobic metabolism

56
Q

electrodes understand flow thats on slides

on skeleton

v6 is on side of individual - midaxillary

A
57
Q

EKG given test strip P, QRS, T wave

given a second one that is not normal

A
58
Q

Hyponatremia

A

low blood sodium

59
Q

Hematrocrit

A

totaly RBC by bloof volume

women have lower hematrocrit levels

however as you get less hydrated it will go up

hematrocrit is the percentage of hematocrit per blood volume

60
Q

Effects of Severve hyperhydration

A

diluting plasma volume

61
Q

Best hydration is

A

Euhydration

62
Q
