Lifetime fitness exam 1 Questions with
Correct Answers
Identify the difference between aerobic and anaerobic metabolism. Correct
Answ_Anaerobic:
-No oxygen
-cell's cyostol
-sources-glucose and protein converted to glucose
-burns fat for 24-48 hours after HI workout
-Fast production of 2 ATP
-Lactic acid-by product
Aerobic:
-oxygen
-fuel: glucose (fructose converted by liver to abdominal fat) & fatty acids (from excess calories,
esp. carbs)
-slow production of large amount of ATP
-CO2 AND H20 byproduct.
-Only burns fat during workout
,Identify and explain the 3 part workout. Correct Answ_1-5-10 min warm up
2-Conditioning period 20-60 min
3-Cool down and flexibility stretch 10 min
Identify and explain 4 stretching types. Correct Answ_Static-Slow sustained stretch and
hold. After exercise
Dynamic-Stretch through activity ROM before exercise.
Bouncing/ballistic- Jerky, rapid bouncing. causes muscle tears and activates stretch reflex
PNF-Contract & relax. Painful & requires a partner. physical therapy.
Identify & explain 6 muscle principles Correct Answ_1-Muscles span joints-attach above &
below a joint and when contracted cause joint movement.
2- Muscles only pull (contract)-they never push.
3- Muscles are arranged in opposition to each other (antagonistic muscle pairs)
4- All or none principle: Electro-chemical stimulus must exceed threshhold for action potential
(contraction) to occur. If the stimulous is above threshhold, all the myofibrils contract. If below,
none contract.
5-Muscle recruitment- fibers are stimulated based on work to be done.
, 6- Resistance- gravity or another force (elastic bands, water, etc. must be resisted for overload to
occur.
Isometric exercise Correct Answ_contraction with no movement (no purpose for developing
strength)
Dynamic exercise Correct Answ_contraction through a ROM
-Isotonic: contraction against constant resistance. Includes body weight, free weight, machine
-Isokinetic: contraction against variable resistance. Traditionally required specialized computer
driven machines.
Phases of dynamic exercise Correct Answ_-concentric contraction: lifting
-eccentric contraction: lowering. Double the length of concentric
Antagonistic Muscle Pairs Correct Answ_Abdominal/Erector Spinae (sit-up/back extension)
(flex back/extend back
Pectoral/trapezius, rhomboids (bench press/seated row) (horizontally adduct
shoulder/horizontally abduct shoulder)
