Q

static stretching

A

the ability to hold an extended position at one end or point in a joints ROM thus making the stretch no longer easy, depends on your ability to tolerate stretched muscles, structure of joints and elasticity of muscles, usually held for 15-30s
ex) how far you can extend your arm across the front on your body

25
diarthrodial joint
the most common and movable type of joint, most flexibility training focuses on increasing the ROM in these joints ex) knees, fingers, elbows
26
ball and socket joint
one of your bones has a ball at the end of it and a connector on the other end to provide us with movement (we have two in the human body) ex) shoulder and hip
27
saddle joint
responsible for all movements except rotation, provides stability to the bones and you cannot actively engage this joint (one area is located in the base of your thumb)
28
pivot joint
ROM is limited to rotation
29
hinge joint
limited to flexion /extension
30
flexion
decreasing the angle between the two bones
31
extension
increasing the angle between the two bones
32
amphiarthrodial joint
little movement | ex) vertebral cord
33
synarthrodial joint
no movement | ex) in your chest region in cartilage, intended to protect organs so no movement is a good thing
34
proprioceptive neuromuscular facilitation (PNF)
alternating contraction and relaxation of the agonist and antagonist muscles ex) pushing someone's leg under tension back towards their chest
35
disadvantage of the PNF?
its a 2 person technique
36
advantage of the PNF?
is the best way to increase flexibility and ROM in a short amount of time
37
agonist
the muscle you are working on | ex) when bending the elbow the biceps are agonist
38
antagonist
the muscle that opposes the action of the other | ex) as the tricep relaxes the bicep contracts
39
percentage of people that have low back pain?
80%
40
spinal cord
a collection of bones that run up your neck, upper, middle and low back that supports weight
41
attachment site
a site for other bones and muscles to attach and support (movement and structural support)
42
ways to encourage good back health?
lift with legs (larger muscle groups), elevated footrest, hold heavy objects close to your body, and practice straight standing posture
43
benefits of muscle fitness?
personal appearance, work and daily activities, and sports skills
44
the most common reason why people work on muscle fitness?
personal appearance
45
muscles cannot...?
turn into a fat cell and fat cells cannot turn into muscles
46
from a health standpoint strength helps to...?
maintain muscle mass, manage body composition, increase bone mineral content, and decreased injury risk
47
resting metabolism
amount of energy (calories) required at rest for proper cell function ex) breathing, circulating blood, basic brain functions
48
what does resting metabolism involve?
basic functions that we don't actively control and lowest amount of energy
49
bone mineral content
how strong your muscles are and how well they are going to perform throughout your lifespan
50
what does strength training provide?
an increase in muscle mass /efficiency and a decrease in body fat
51
androgens
male steroid based hormones
52
types of muscles?
smooth, cardiac and skeletal
53
smooth muscle tissue
long spindle shaped fibers containing only one nucleus that help make up some of your organs, involuntary muscle
54
cardiac muscle tissue
found only in the heart, involuntary muscle, specialized tissue and doesn't regenerate itself
55
skeletal muscle tissue
long, cylindrical shaped, multi nucleated, makes up thje largest part of the body (40% body mass) and functions to move the skeleton to perform movement patterns, voluntary control
56
skeletal muscle structure?
each of our muscles is broken up into bundles, each bundle is made up of muscle fibers, each fiber is formed by myofibrils and are composed of sarcomeres
57
fibers
primarily contribute to efficiency in the work that you do (can become stronger and allow you to endure more)
58
myofibrils
thin strands which help us generate force which allow you to move your skeletal muscles, comprised of sarcomeres
59
sarcomeres
small stacked striped units that appear due to actin and myosin filaments
60
actin and myosin filaments
exist within our muscles that sit in an alternating fashion, engage in the sliding filament theory (slide among one another), creating friction that we have to overcome which produces energy to move the skeletal parts of the body
61
the skeletal muscle is classified by which two factors?
the speed with which they contract and their main energy system
62
types of muscle fibers?
slow twitch oxidative fibers, fast twitch glycolytic fibers and fast twitch oxid-glyco fibers
63
slow twitch oxidative fibers
red muscle fibers that hold myoglobin (a substance in the blood that attracts oxygen), contract slowly and are involved in aerobic activities
64
fast twitch glycolytic fibers
white fibers (doesn't require oxygen), contract quickly but tire rapidly and are involved in anaerobic activities
65
fast twitch oxid-glyco fibers
pink fibers (in between fiber, uses oxygen), most beneficial, contracts faster than red fibers and slower than white fibers, and tires before red fibers but after white
66
functions of muscles?
movement, heat generation, postural maintenance, and joint stability
67
factors that determine strength?
heredity, muscle size, leverage, muscle mechanics, neural factors and fiber types
68
heredity
what influences everything else, limiting factor
69
hypertrophy
an increase in the size of cells and corresponds to muscular endurance
70
hyperplassia
an increase in the number of cells and corresponds to muscular strength
71
leverage
allows us to move weight /resistance and most levers in the body are third class
72
longer fulcrum to load =
less weight lifted (greater amount of effort required)
73
muscle mechanics
the time between phases as we elongate the tendons and muscles ex) like an elastic- the longer you hold it the less energy it will have, where as if you let it go right away there is more energy
74
quick stretch and immediate shortening =
increased force /weight lifted
75
static training exercises
isometric
76
isometric
the joint angle stays the same which means there's no change in the length of your muscles as your engaging it to contract (high force produced, lots of resistance, 0 change in ROM) ex) stationary solid objects, door sills i.e., carrying an object in front of you
77
dynamic training exercises (most common form)
isotonic, plyometrics, speed loading and isokinetic
78
isotonic
amount of resistance is changing through the ROM, muscle contracts and shortens /lengthens
79
what are the two phases of an isotonic contraction?
concentric and eccentric
80
concentric (positive phase)
muscle contracts and shortens, bulking up, and always moves against gravity ex) bicep curl
81
eccentric (negative phase)
muscle contracts and lengthens with gravity | ex) lowering a barbell in a bicep curl
82
plyometrics
quickly eccentrically loading a muscle and then at the end a concentric contraction occurs ex) box jumps
83
speed loading
increasing the resistance in a skill based movement usually in a weighted fashion ex) baseball players who warm up with a weighted bat (heavier resistance)
84
isokinetic
max resistance during a full ROM, continuous, typically done with a computerized system ex) rehab setting
85
progressive resistance exercise
increased strength by progressively increasing stress on the muscle
86
recommended rest in between sets?
3-5s rest = 50% recovery | 3-5min rest = full recovery
87
recommended rest in between workouts?
complete recovery = 48 hours
88
top good foods according to Ilsa?
ice cream, caffeine, red wine, chocolate, dirt and fish
