force velocity relationship

Question 1

Types of contractions that relate to the force-velcoity relationships?

Answer 1

1)isometric contraction-no velocity produces force without length
2)concentric contraction-when muscle shorten with a load velocity increases e.g biceps curl
3) eccentric contraction muscle lengthens to produce force. When a load is greater than a muscle can produce. produces higher forces at same velocity as concentric Nordics

Question 2

force velocity relationship examples?

Answer 2

1) higher velocity with lighter load
2)l
3)

Question 3

define the what force velocity relationship is?

Answer 3

The force-velocity relationship in muscles describes the inverse relationship between the force a muscle can generate and the velocity at which it contracts. This relationship is a fundamental concept in muscle physiology and has implications for how muscles function during different types of movements. The force-velocity relationship can be summarized as follows:

Question 4

How des this force relationship relate to the types of fibers?

Answer 4

type 1) -low force production, slow contractions has a more gradual decline in force while velocity increases, think of long distance runner
type 2a) moderate velocity, more force than type 1 but less than 2x. shows steep decline in force with increasing velocity
type 2x) contract rapidly producing larger forces, with high contractile velocity. shows steep decline in force with increasing velocity
