resistance exercise

Question 1

key elements x3

Answer 1

strength, power, endurance

Question 2

resistance exercise

Answer 2

activity in which muscle contraction is resisted by & outside force

Question 3

functional strength

Answer 3

ability of NM system to produce the appropriate amount of force to accomplish functional tasks smoothly

Question 4

strength training

Answer 4

space using muscle force to raise, lower, or control heavy load over a short period of time

Question 5

power training

Answer 5

ballistic movements involving strength + and speed

Question 6

muscle endurance

Answer 6

the ability of a muscle to contract repeatedly against an external load & resist fatigue over time

Question 7

endurance training

Answer 7

using muscle force over an extended period of time

Question 8

overload principle

Answer 8

resistance > metabolic capacity to improve muscle performance

Question 9

SAID principle

Answer 9

• task-specific training = practice of actual task

Question 10

reversibility principle

Answer 10

adaptive changes in response to a resistance exercise program are transient

• if you don’t use it, you lose it
• reg. exercising to keep mm
• detraining = 1-2 weeks

Question 11

type I mm fibers

Answer 11

slow twitch
high resistance to fatigue (postural mm)

Question 12

type II mm fibers

Answer 12

fast twitch
low resistance to fatigue

Question 13

hypertrophy

Answer 13

increase in size of mm fibers
- 4 to 8 weeks

Question 14

hyperplasia

Answer 14

increase # of mm fibers

Question 15

external stabilization

Answer 15

therapist/equipment
- pta holds hip down

Question 16

internal stabilization

Answer 16

contraction of adjacent mm group
- within the pts

Question 17

isometric exercise : used to decrease pain/spasms & promote relaxation/circulation @ ACUTE stage

Answer 17

muscle setting

Question 18

isometric exercise : submax but sustained contraction against reistance in antigravity of WB positions

Answer 18

stabilization

Question 19

Isometric exercise : resistance applied @ multiple jt positions, used when goal is to improve strength throughout ROM when dynamic RT is painful/not allowed

Answer 19

multiple angle

Question 20

manual resistant

Answer 20

therapist or self-regulated

Question 21

mechanical resistance

Answer 21

equipment/machine

Question 22

isometric exercise

Answer 22

static mm contraction w/o visible jt movement

Question 23

concentric

Answer 23

shortened mm

Question 24

eccentric

Answer 24

lengthened mm

Question 25

variable resistance

Answer 25

bands, different levels

Question 26

constant resistance

Answer 26

weights, same level

Question 27

isokinetic exercise

Answer 27

predetermined, constant velocity (same speed)

Question 28

open kinetic chain

Answer 28

the terminal segment is free to move in an unrestricted manner

Question 29

closed kinetic chain

Answer 29

the terminal segment is restrained

Question 30

Capacity of muscle to do work (force x distance)

Answer 30

muscle performance

Question 31

Extent that the contractile elements of muscle produce force

Answer 31

strength

Question 32

strength + speed

Answer 32

power

Question 33

Ability to perform activities over prolonged period of time - cardiopulmonary - muscle

Answer 33

endurance

Question 34

contraindications x4

Answer 34

severe jt/mm pain during active movement w no load acute inflammation severe cardiopulmonary disease inflammatory NM/mm disease - polymyositis - dermatomyositis - guillain-barre: temp problem
