Is the amount of force a muscle can produce with a single maximum effort quizlet?

Terms in this set (9)

1. One Repetition Maximum - maximum amount of weight lifted once.
2. Dynamometer Techniques - a strength testing dynamometer usually consists of a spring of some type which is deformed a certain amount
when a specific force is applied to it. (eg) - hand grip dynamometer.
- measures isometric strength
- relatively inexpensive, high reliability if body position is carefully standardized for each trial of the test.
3. Computer-Assisted, Isokinetic Methods - equipment such as Cybex,
Biodex, KIN/COM, etc.
- isokinetic machine, but many of these machines can also test strength in isometric, concentric, and eccentric modes
- has a microcomputer which can be programmed at any initial and final force, angle, velocity, or number of repetitions.
- accurate and reliable, but expensive

Muscular Strength and Endurance

Terms in this set (17)

muscular strength

the amount of force a muscle can produce with a single maximum effort

muscular endurance

the ability to resist fatigue while holding or repeating a muscular contraction

muscle fiber

a single muscle cell, usually classified according to strength, speed of contraction, and energy source

myofibrils

protein structures that make up muscle fibers

hypertrophy

increased size of muscle fiber

atrophy

decrease in size of muscle fiber

hyperplasia

increase in number of muscle fibers

slow twitch fibers

this type of muscle fiber is: fatigue resistant, don' contract as rapidly and forceful, and rely primary on the aerobic energy system

fast twitch fibers

these type of muscle fibers: contract rapidly and forcefully, fatigue more quickly, and rely more on the anaerobic energy system

motor unit

a motor nerve (one that initiates movement) connected to one or more muscle fibers

muscle learning

the improvement in the body's ability to recruit motor units, brought about through strength training

cardiovascular disease and diabetes

strength training helps manage and prevent ______ and _____.

static (Istometric) exercise

involves a muscle contraction without a change in the length of muscle or joint angle

dynamic (isotonic) exercise

exercise involving a muscle contraction with a change in the muscle's length

concentric contraction and eccentric contraction (pilometric)

the 2 types of dynamic exercise are ____ and ______.

set

group of repetitions followed by a period of rest

volume

product of frequency, intensity, and time

Is the amount of force a muscle can produce with a single maximum effort?

Muscular strength refers to the amount of force a muscle can produce with a single maximal effort. Muscle strength is measured during muscular contraction. The size of your muscle fibers and the ability of nerves to activate muscle fibers are related to muscle strength.

Is the amount of force a muscle can produce quizlet?

Muscular strength is the amount of force a muscle can produce with a single maximum effort; while muscular endurance is the ability to hold or repeat a muscular contraction for a long time.
