Deck 5 Muscular System-Responses

Question 1

Names all 6 responses of the muscular system

Answer 1

Increased blood supply/ increased muscle temperature/ increased muscle pliability/ lactic acid accumulation/ micro tears/ DOMS

Question 2

Define vasodilation and state which response it is associated with

Answer 2

Vasodilation- the widening of blood vessels (internal lumen) to allow more blood flow. INCREASED BLOOD SUPPLY.

Question 3

What fuels are broken down that creates heat as a by-product (increased muscle temperature)

Answer 3

Carbohydrates and fats.

Question 4

Increasing muscle temperature also increases muscle………………. This decrease the chance of ………… and increase the ranges of movements at joints.

Answer 4

Increasing muscle temperature also increases muscle PLIABILITY. This decrease the chance of INJURY/ STRAINS and increase the ranges of movements at joints.

Question 5

Lactic acid is a waste product of what type of exercise?

Answer 5

Anaerobic exercise.

Question 6

Decsribe the negative effects of a lactate accumulation.

Answer 6

This build up, results in rapid fatigue.
It also impedes muscle contractions.

Question 7

TRUE or FALSE
Micro tears are a mucular response to resistance/weight training.

Answer 7

TRUE

Question 8

Describe what happens after micro tears occur.

Answer 8

Training improvements are made when we rest; allowing repair.
After micro tears repair the muscles become a little stronger.
Protein will support the repair.

Question 9

What does DOMS stand for?

Answer 9

Delayed onset of muscle soreness

Question 10

State 3 characteristics of DOMS.

Answer 10

DOMs is the pain felt in the muscle 24-48 hours after exercise.
DOMs is caused by micro-tears.
They occur if you’re not accustomed to high intensity exercise.
