Pregunta 1
Pregunta
Which of the following are characteristics of isokinetic exercises?
Respuesta
-
Fixed Speed with Variable Resistance
-
Machine accommodates itself to the user throughout the ROM
-
The machine will only move at a given speed; and it maintains the speed by adjusting the resistance relative to the force being received.
-
Load is dependent on the velocity of limb movement throughout the arc of motion.
-
By controlling the speed of the exercise, maximum resistance throughout the full ROM is developed and all points of range can be worked maximally.
-
Can accommodate muscle fatigue as well as painful arc.
-
Muscles can be worked in both concentric and eccentric contractions.
-
Good choice for strengthening when a person has pain with joint movement, but still needs to gain or at least maintain muscle strength
-
Good choice for gentle muscle pumping soon after surgery
-
Combination of an eccentric load followed by a fast concentric contraction

Pregunta 9
Pregunta
Plyometrics is the combination of a concentric load followed by a fast eccentric contraction.
Pregunta 10
Pregunta
A plyometric activity is a quick, powerful movement involving pre-stretch of the muscle (eccentric), and activates the “stretch-shortening cycle” to produce a stronger concentric contraction.
