LMBR6: PHYSICAL ACTIVITY P1. p 185-196

Question 1

How important is physical inactivity as a risk factor for global mortality ?

What proportion of premature deaths is due to physical inactivity ?

Is non-vigorous physical activity of benefit ? If so, in what way ?

BR 185, 191

Answer 1

Physical inactivity is the fourth leading risk factor for global mortality

Physical inactivity => 1 in 10 premature deaths.

Non-vigorous physical activity reduces all cause mortality

Question 2

Define physical activity

BR 216

Answer 2

Physical activity is any movement of the body done through skeletal muscle contraction that causes the energy expenditure to be beyond its baseline

Mn: PA Sk MEEB

Question 3

Define exercise

Answer 3

Question 5

What does physical fitness include (9)

Answer 5

Includes fitness in the following categories:

Flexibility, Agility, Speed (integrative)

Question 6

1. What is deconditioning?
2. Complete: “If deconditioning was recognized as a disease, it would be more common than __ or __”

Answer 6

BR 216

Deconditioning is a state of health that occurs from being consistently Physically Inactive and lacking exercise in ones daily life, all of which results in Functional Losses.

Complete: “If deconditioning was recognized as a disease, it would be more common than hypertension or diabetes”.

Mnemonic: FLoPI (“floppy”)

“Functional losses resulting from being consistently Physicall inactive.”

Question 7

What is the best definition of aerobic or endurance exercise ?

Answer 7

Aerobic or Endurance Exercise:

Where the body’s Large muscles move in a Rhythmic manner for a sustained period of Time.

Mnemonic: “Running after the L-R-T” (=Light Rapid Transit train)

• Large muscles move in a…

• sustained period of Time

Question 8

Define cardiorespiratory endurance.

Answer 8

The ability to continue aerobic exercise like walking or running.

BR p216

Question 9

What is skeletal muscle endurance ?

BR 216

Answer 9

The ability to continue holding weight or position

Mn: FASEBB guy w weight & position

Question 10

What is skeletal muscle strength ?

What is it equal to ?

BR 216

Answer 10

Skeletal muscle strength is the maximum force a muscle or muscle group can produce at a specified velocity.

This is equal to one repetition maximum (1RM)

Question 11

What is skeletal muscle power ?

BR 216 & here

Answer 11

Skeletal muscle power is the the RATE of WORK - ie the amount of work completed by a muscle in a period of time.

Work = Force x distance

Power = Work x time

Question 12

BR 216

Answer 12

The ability to move a joint closer to its full range of motion. (F.R.O.M.)

Question 13

What is balance

BR 216

Answer 13

The ability to withsand destabilizing stimuli (especially imporant with age)

Question 14

What is speed of movement ?

BR 216

Answer 14

The distance traveled in a period of time

Question 15

What is reaction time ?

BR 216

Answer 15
