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
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
Define physical activity
BR 216
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
Define exercise
BR 216
Exercise is purposeful physical activity that is organized, planned and recurring, and that is done with the intent of improving or maintaining one or more components of ones health.
Define fitness
Complete: “Fitness is the outcome of __ “
BR 216
Fitness is the abiity to perform one’s activites of daily life, respond to emergencies , and enjoy leisure time activities with sufficient energy and vitality and without excess fatigue.
=> “Fitness is function without fatigue”
Fitness is the outcome of exercise
What does physical fitness include (9)
BR 216
Includes fitness in the following categories:
Flexibility, Agility, Speed (integrative)
Endurance (SkM & Cardiorespiratory), SkM strength & power
Balance, Body composition
Mnemonic: FASEBB
What is deconditioning
Complete: “If deconditioning was recognized as a disease, it would be more common than __ or __”
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”.

What is the best definition of aerobic or endurance exercise ?
BR 216
Aerobic or Endurance Exercise:
Where the body’s Large muscles move in a Rhythmic manner for a sustained period of Time.
Mn: Saying on an elliptical, L-R-T
Define cardiorespiratory endurance
BR 216
The ability to continue aerobic exercise like walking or running
What is skeletal muscle endurance ?
BR 216
The ability to continue holding weight or position
Mn: FASEBB guy w weight & position
What is skeletal muscle strength ?
What is it equal to ?
BR 216
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)
What is skeletal muscle power ?
BR 216 & here
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
What is flexibility ?
BR 216
The ability to move a joint closer to its full range of motion. (F.R.O.M.)
What is balance
BR 216
The ability to withsand destabilizing stimuli (especially imporant with age)
What is speed of movement ?
BR 216
The distance traveled in a period of time
What is reaction time ?
BR 216
The time it takes to react to some stimili
