Grade I mobilization is what size amplitude?

A

small

156
Q

Grade II mobilization is what size amplitude?

A

large

157
Q

Grade III mobilization is what size amplitude?

A

large

158
Q

Grade IV mobilization is what size amplitude?

A

small

159
Q

Convex moving on concave will be

A

opposite directions

160
Q

Any movement beyond end range is considered

A

stretching

161
Q

Stress-strain curve: toe region

A

initial stress that results in the wavy collagen fibers becoming straight and aligning with one another

162
Q

Stress-strain curve: elastic region

A

added stress to the tissue results in greater deformation, though the tissue returns to its resting length if the stretch is not maintained. Tissues with greater stiffness will have a steeper slope in this portion of the curve.S

163
Q

Stress-strain curve: plastic region

A

addition of more stress results in permanent deformation even after the stretch force is no longer applied due to the failure of bonds between the collagen fibers.

163
Q

What is the principle for the basis of stretching?

A

creep

163
Q

What is creep?

A

soft tissue that is stretched for a sustained duration will elongate and not return to its original length after the load is removed due to viscoelastic property

163
Q

Middle layer of muscle fibers that wraps muscle fibers into groups called fasciculus

A

perimysium

163
Q

Innermost connective tissue of muscle that enwraps the individual muscle fibers

A

endomysium

Q

Myofibrils make up

A

sarcomeres

163
Q

Outermost connective tissue layer of muscle that surrounds the entire muscle.

A

epimysium

163
Q

Subunits of muscle

A

myofibrils

164
Q

Sarcomeres are made up of….

A

actin and myosin

165
Q

A

without a change in muscle length

166
Q

Isotonic

A

constant load
concentric and eccentric

167

equipment

168
Q

Power training reps and sets

A

low reps very high intensity

169
Q

Volume in strength training is calculated by

A

of reps x intensity

170
Q

Exercise sequence

A

large muscles first then small
multi-joint before single joint
high intensity before low intensity

171
Q

DeLorne exercise programming

A

1st: 50% (of 10 rep max) @10 reps
2nd: 75% (of 10 rep max) @10 reps
3rd: 100% (of 10 rep max) @10 reps

172
Q

Oxford exercise programming

A

1st: 100% (of 10 rep max) @10reps
2nd: 75% (of 10 rep max) @10 reps
3rd: 50% (of 10 rep max) @ 10reps

173
Q

SAID

A

specific adaptation to imposed demands

174
Q

Reversibility principle

A

reversible effects can begin within 1-2 weeks of stopping an exercise program

175
Q

length-tension relationship

A

muscle can produce maximal force near its normal resting length. If it lengthened or shortened it will likely produce less force.

176
Q

force-velocity relationship

A

speed of muscle contraction affects the force
concentric= as speed increases, force decreases
eccentric= as speed increases the force also increases

177
Q

Moment arm

A

linear distance from the axis of rotation to the site of the external load

178
Q

power

A

rate at which work is performed
work/time

179
Q

torque

A

ability of external load to produce rotation around an axis, calculated by multiplying the magnitude of the load by the moment arm

180
Q

work

A

magnitude of load multiplied by the distance the load is moved
weight x ROM

181

A

IIA

182
Q

During strength training what happens to capillary bed density?

A

decreases or there is no change

183
Q

During strength training what happens to mitochondria?

A

decreased density

184
Q

What happens to ATP during strength training?

A

increases stores

185
Q

Which type of muscle fibers are resistant to fatigue?

A

I

186
Q

DOMS characterized by

A

tenderness to palpation in the muscle belly or at the muscle-tendon junction

187
Q

What types of exercises reduce the likelihood of DOMS?

A

concentric and isometric

188
Q

Edema vs effusion

A

edema: outside joint capsule
effusion: inside joint capsule

189
