Term
what is 1-RM testing?
Definition
Term
what is the RPE scale for resistance training?
Definition
Utilizes a 1-10 Scale
10 = Max Effort
9 = Could Have Completed 1 More Rep
8 = Could Have Completed 2 More Reps
7 = Could Have Completed 3 More Reps
Term
what is the difference between the RPE scale for resistance and endurance testing?
Definition
resistance RPE is on a scale of 1-10
endurance RPE is on a scale of 6-20
Term
what does static stretching lead to? what does it decrease?
Definition
leads to a deformation of the tissues around the muscle
decreases muscle stiffness by causing a change in tension of the musculotendinous unit
Term
what does dynamic stretching lead to?
Definition
increase strength, power, jumping, and sprinting performance
Term
what is the 5 criteria for a VO2 max test?
Definition
plateau in oxygen with increasing workload
RER greater than 1.15 (RER=VCO2/VO2)
RPE greater than 17
lactate levels over 8 mMols per deciliter
HR should be within 10 beats of APMHR or fail to increase with any further increases in workload
Term
what does PFT stand for?
Definition
Pulmonary function testing
Term
what does the BodPod displace?
Definition
air
Term
what does hydrostatic weighing displace?
Definition
water
Term
what is EPOC?
Definition
excess post exercise oxygen consumption
oxygen debt
after exercise oxygen consumption does not return to resting levels immediately
Term
what is the valsalva maneuver?
explain how to do it?
Definition
a forceful attempt at expiration when the airway is closed

Take a deep breath into your stomach and squeeze your abdominals as hard as you can, then hold that breath for the entire repetition
Term
what effect does resistance training have on muscle tissue?
Definition
hypertrophy
Term
what effect does endurance training have on muscle tissue?
Definition
increase mitochondria, capillaries
become more oxidative
Term
what is COPD?
is it obstructive or restrictive?
Definition
constant obstructive pulmonary disease
obstructive
Term
what is an ELISA?
Definition
Enzyme-Linked Immunosorbent Assay (ELISA) protocol- done to determine the prevalence/quantity of a particular protein (antigen/antibody) in a substance (serum/plasma).
Term
what are the three types of ELISAs?
Definition
indirect
direct
competitive
Term
what is an indirect ELISA?
Definition
Each well is coated with a specific ANTIGEN
Antibodies attaches to antigen.
An enzyme-linked antibody is added, followed by a substrate.
MORE COLOR=MORE PREVALENCE
Term
what is a direct ELISA?
Definition
Most common ELISA.
Each well is coated with a specific ANTIBODY.
Antigens attaches to antibodies in the wells.
An enzyme-linked antibody is added, followed by a substrate.
MORE COLOR=MORE PREVALENCE
Term
what is the formula for cardiac output?
Definition
heart rate * stroke volume
Term
what is the formula for APMHR?
Definition
220-age
Term
what does BMR stand for?
Definition
basal metabolic rate
the minimum amount of energy your body needs to survive
Term
what does RMR stand for?
Definition
resting metabolic rate
the amount of energy your body uses at rest.
Term
what is the percent difference in VO2 max between males and females?
Definition
20-25% difference between untrained males and females
less than 10% difference between trained males and females
Term
what is the average VO2 max for females?
Definition
30-40 ml/kg/min
Term
what is the average VO2 max for males?
Definition
40-50 ml/kg/min
Term
what was the highest recorded VO2 max in males?
Definition
97.5 ml/kg/min
Term
what was the highest recorded VO2 max in females?
Definition
77 ml/kg/min
Term
T/F
H + Bicarbonate -> Carbonic acid -> H2O + CO2
Definition
true
Term
1 pound = kg?
Definition
0.454
Term
1 inch = cm?
Definition
2.54
Term
what is the average, healthy FEV1/VC ratio?
COPD patients?
Definition
80%
can drop to 40%
Term
what is the unit of measurement for relative VO2?
Definition
ml/kg/min
Term
what is the unit of measurement for absolute VO2?
Definition
L/min
Term
what is the unit of measurement for blood pressure?
Definition
mmHg
Term
what is the unit of measurement for heart rate?
Definition
beats per minute
Term
how do you identify the lactate threshold?
Definition
the point on the graph right before the lactate concentration rises systematically
Term
what is the size principle of motor unit recruitment?
why do we have to work up to a max?
Definition
states that in order to move a load, muscle units are recruited from small/slow/fatigue resistant to large/fast/less fatigue resistant

We want to recruit as many motor units as posible, so we use a protocol that allows us to sequentially recruit more motor units without becoming overly fatigued
Term
how do you change relative VO2 to absolute VO2?
absolute to relative?
Definition
mL -> L; divide by weight in kg

L -> mL; multiply by weight in kg
Term
how many mL are in one L?
Definition
1000
Term
explain O2 deficit.
Definition
the lag in oxygen consumption at the onset of exercise.

the difference between the actual amount of oxygen consumed and the amount of oxygen required during steady-state exercise from the start of exercise.
Term
what happens during EPOC?
Definition
Return of O2 which has been depleted from the blood and muscles during exercise
Return of ATP and PC which have been depleted during exercise
Removal and conversion of the lactic acid, accumulated during exercise.
Term
who has a higher resting heart rate, males or females?
Definition
females
Term
what factors effect lung volumes?
Definition
pregnancy
height
gender
smoker
Term
what is auto regulation?
Definition
is a method of training in which you allow your effort on any given day, or more specifically on any given set, to determine the amount of weight you will use next
Term
what is the main source of error in hydrostatic weighting?
Definition
Term
what does the Harris Benedict Equation predict?
Definition
RMR
Term
[image]
Definition
A = oxygen deficit
B = oxygen debt
C = Steady State oxygen consumption
D = Resting oxygen consumption
E = oxygen requirement
