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

25
Hypovolemia
Severe Dehydration low plasma volume (results in a higher RBC count than plasma)
26
Anaerobic Glycolysis
- 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
Aerobic Glycolysis
- Low to submaximal effort for 30 seconds or more.
28
Blood Pressure Assessment Procedures
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
New Guidelines for Blood Pressure Categories
-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
Explanation of protocol for Manual Wingate Test
1) Warm-up (5-min) 1. Include two 15 sec sprints 2. Test (30sec) 3. Cool Down (5 to 10 min)
31
𝑉O2
The ability of the pulmonary, cardiovascular, and muscular systems to absorb, transport and utilize oxygen
32
absolute 𝑉O2
L/min total amount of oxegen you breathe in
33
relative 𝑉O2 ask lindsey
mL/kg/min amount of oxegen you enhale relative to your weight
34
sub-maximal test,
The testing protocol is performed at a low enough intensity, so the subject does not reach failure during the assessment
35
𝑉CO2
Volume of CO2 VCO2/VO2 and RER
36
RER
respiratory exchange ratio Ratio between amount of CO2 produced and O2 consumed in one breath 1.1 RER ask lindsey
37
Physiological rationale for 𝑉O2 max testing. Clinical Setting? Performance Setting?
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
𝑉O2 max and work rate
higher work rate the higher your VO2 max
39
𝑉O2 and heart rate
closer to VO2 max closer to heart rate max
40
𝑉O2 and RER
as VO2 max increases RER increases measurement of CO2/O2
41
Running a 𝑉O2 max test from start to finish using any protocol
Bruce protocol Warm up 3-5 min Test: 3 min Speed and grade increase with each stage
42
electrode placement for chest leads
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
lactate
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
Does a higher or lower lactate threshold indicate enhanced performance
Higher
45
Erythropoietin
increases red blood cells and hemoglobin production
46
blood composition
1) Red blood cells ( erythrocytes) 2) White blood cells (leucocytes) 3) Platelets ( Thrombocytes)
47
Effects of severe dehydration
- reduces ICF and ECF - Thermoregulation can get messed up - Blood flow can be affected
48
Factors that affect VO2
Hereditary Sex Age 15 through 18 Training status Mode of exercise
49
ECG spreadsheet form 8 or 9 points a vo2 absolute relative catagory know what to circle
50
VO2 max vs. VO2 peak was this a vo2 max or a peak
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
LACTATE THRESHOLD
RIGHT BEFORE it shoots up many units not 0.1 more than that
52
lactate
anaerobic metabolism turning it on less blood flow to liver and kidneys and lactate tissues
53
Resting Blood Lactate is around 0.5- 2.0 Note when finding lactate threshold
54
same individual that becomes more fit the deflection or lactate threshold will come later in a graded exercise testing BOTH TEST
55
Physiological rationale for lactate threshold ASK LINDSEY
indications of anaerobic metabolism
56
electrodes understand flow thats on slides on skeleton v6 is on side of individual - midaxillary
57
EKG given test strip P, QRS, T wave given a second one that is not normal
58
Hyponatremia
low blood sodium
59
Hematrocrit
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
Effects of Severve hyperhydration
diluting plasma volume
61
Best hydration is
Euhydration
62
LBM - Lean Body Mass
is weight left over after calculation
