lab methods final exam

Question 1

define muscular strength

Answer 1

the muscles ability to exert a maximal force on one occassion

Question 2

define muscular endurance

Answer 2

the muscles ability to preform successful repetitions against a sub maximal load

Question 3

define flexibility

Answer 3

the functional capacity of joints to move through a full ROM

Question 4

defien cardiorespitory fitness

Answer 4

the ability of the body’s respitory systems and circulatory to deliver oxygen to the muscles during physical activity

Question 5

define isometric

Answer 5

generation of force without change in muscle length

Question 6

define isotonic

Answer 6

A fixed amount of resistance

Question 7

define isokenetic

Answer 7

fixed movement speed

Question 8

what affects flexibility

Answer 8

age, gender,type of joint, previous injuries, adipose tissue

Question 9

If you did a graded exercise test, what is the risk of an cardiac event happening

Answer 9

low- during or immediate after aGTX is 0.06%

Question 10

what percentage of the body weight does skeletal muscle account for in men and woman?

Answer 10

40%-males
23%-females

Question 11

what determines an athletes pace in an endurance event?- What measure of fitness

Answer 11

LT when expressed as an % of V02max

Question 12

why would we use a belt in squatting and how would it help

Answer 12

supports lumbar and lower back during heavy lifts

increases intro-abdominal pressure

can be risky when not using a belt because stomach muscles aren’t use to contracting to support the spine.

Question 13

which test are appropriate for muscular power

Answer 13

vertical jump

Question 14

what is the SEE for most sub max cardiorespitory fitness test

Answer 14

+-10-20%

Question 15

what 3 factors contribute to total daily expedentire

Answer 15

resting metabolic rate 60-75% of TDEE

Thermogenic effect of food (10% of TDEE)

Energy expended during PA and recovery (15-30% of TDEE)

Question 16

Why is resting metabolic rate lower in women?

Answer 16

Low ffm
they have more body fat percentage
women burn less energy at rest than men

Question 17

what affect does a fever or overreacted thyroid have on resting metabolic rate

Answer 17

resting metabolic rate increases
your body burns more calories at rest

Question 18

what affect does age have on resting metabolic rate and what can we do about it

Answer 18

RMR decreases 2-3% per decade due to a decrease in fat free mass and an increase in fat mass

have a balnaced diet
maintain muscle mass through regular strength training

Question 19

difference in diagnostic and prognosis test

Answer 19

Diagnostic: exercise testing used along ECG to diagnos CAD (treadmill stress test)
Prognosis: Exercise testing to project outcomes (cardiovascular risk profiles)

Question 20

what is an RPE scale and what is it used for

Answer 20

Rate of perceived exertion
it is used to assess how hard someone feels while doing physical activity
on a scale of 6 to 20

Question 21

percent of Vo2max accounted for by genetics

Answer 21

50%

Question 22

what could be problematic about estimating a person’s 1RM from those like 6-10 RM test

Answer 22

it can lead to a less accurate assessment of their true maximum strength due to the inherent difficulty in predicting how much weight they could lift for just one repetition based on a higher rep range,

Question 23

whats the difference between relatives and absolute values when testing

Answer 23

abssolute: Capacity without taking body weight into account
relative: Accounted for by using your weight

Question 24

3 reasons that cause poor posture

Answer 24

sitting and standing with back curved

insufficient sleep or chronic fatigue

excess body weight

Question 25

whats the difference between active and passive ROM

Answer 25

Active: motion achieved without assistance by an examiner

Passive: MOTION ACHIEVED BY EXAMINER WITHOUT ASSITANCE FROM CLIENT

Question 26

Strength and weaknesses of PA assessment tools

Answer 26

Strengths: concurrent measure of activity, ability to continuously record for multiple days out the week, can differ light, moderate, and vigorous PA

Weaknessess: can be expensive, or unable to assess activity type (weight lifting, cycling into wind, running uphill)

Question 27

what determines rather someone hits their max or not?

Answer 27

requires two submaximal heart rates 110 bpm and 85% of age predicted max HR at 2 different stages
