When a client complains of pain in their joints, is it in your scope of practice to diagnose their
condition?

Answer 10

No, this would not be within your scope of practice to diagnose

Question 11

Define exercise physiology

Answer 11

exercise Physiology—the study of the cellular functions in the human body before,
during and after exercise

Question 12

What is the

basic unit of life?

Answer 12

the cell

name the three energy systems

Answer 13

atp creatine phosphate system glycolysis aerobic oxidation

Question 14

which energy systems are anaerobic? aerobic?

Answer 14

the atp cp system and glycolysis are considered anaerobic the aerobic oxidation system is aerobic

Question 15

t/f the term anaerobic means oxygen is not required to function

Answer 15

true

Question 16

give three examples of activities that primarily require use of the ATP CP system

Answer 16

weight lifting sprinting tennis

Question 17

what is glycolysis how long does it last

Answer 17

glycolysis is the breakdown of carbohydrate to pyruvate or lactic acid to produce atp it last from ten seconds to three minutes

Question 18

what is lactate threshold

Answer 18

lactate threshold the accumulation or rise in lactate

Question 19

what is glucose where is it stored what is it stored as

Answer 19

blood sugar is the main source of anaerobic atp production glucose is stored in the muscles and liver glucose is stored as glycogen

Question 20

what is aerobic oxidation

Answer 20

the aerobic pathway to produce atp

Question 21

what part of the musculoskeletal system allows the human body to move

Answer 21

skeletal muscle

Question 22

what are the three types of connective tissue that encompass muscle

Answer 22

endomysium perimysium epimysium

Question 23

what is a myofibril what are the two myofilaments that compose a myofibril

Answer 23

myofibril the smallest unit of a muscle cell actin (thin) and myosin (thick) filaments

Question 24

what are the two types of muscle fibers explain the difference between the two

Answer 24

speed of contraction and force output

Question 25

what muscle fiber type is predominantly involved in activities such as sprinting, power lifting, and the high jump

Answer 25

type 2b

Question 26

define the all or none principle

Answer 26

all or none principle when a myofiber is innervated by a nerve cell, the myofibrils contract totally or not at all

Question 27

what are the three types of contraction list them in the order of strength from strongest to weakest

Answer 27

eccentric isometric concentric

Question 28

define concentric strength

Answer 28

concentric strength the amount of musculoskeletal force to overcame a resistance by a shortening of the muscle fibers

Question 29

define eccentric strength

Answer 29

eccentric strength the amount of musculoskeletal force displayed when a muscle is lengthened under tension

Question 30

what is the function of blood

Answer 30

blood delivers oxygen and nutrients to the cells of the body blood also retrieves waste products from the cells and carries them to be expelled or metabolized

Question 31

define periodicity

Answer 31

is the gradual cycling of specificity intensity or volume of training to achieve a specific goal

Question 32

what is the overload principle

Answer 32

Overload principle—the attempt to challenge the musculoskeletal system with unaccustomed stimulation such as, but not limited to, increased weight, speed, or volume of training (number of sets or reps

Question 33

what are the five major factors that effect training

Answer 33

Level of fitness, intensity, duration, frequency, genetics.

Question 34

explain the difference between using free weights and selectorized equipment

Answer 34

Free weights can be used in several exercises, but not all; selectorized uses only select muscle groups. Free weights are functional, real life easy to transport; selectorized doesn’t require a spotter, safer and easier to change resistance. Fr ee weights require more technique; machines do not fit everyone and can limit ROM. Free weights usually require more stabilization than machines.

Question 35

what is atp

Answer 35

Adenosine Triphosphate.

Question 36

what would afferent information be

Answer 36

Afferent information is nerve impulses from receptors or sense organs toward the central nervous system.

Question 37

what is a motor unit

Answer 37

Is a single a-motor neuron and all of the corresponding muscle fibers it innervates.

Question 38

what are the three types of muscle tissue

Answer 38

Skeletal, cardiac and visceral.

Question 39

what are the prime movers or agonists in a biceps curl

Answer 39

Biceps Brachii, brachioradialis and brachialis.

Question 40

what would the training heart rate of 70% be for a 32 year old female with a resting heart rate of 72

Answer 40

``` 220 - Age x % = THR = 131.6 or 220 - Age - RHR x % + RHR = THR = 153.2 or 220 - Age x % x 1.15 = THR = 151.34 (beats per minute) ```

Question 41

give a few examples of signs of overtraining

Answer 41

Elevated resting heart rate, difficulty sleeping, fatigue, excessive weight-loss, excessive soreness.

At night.
