NCCPT
a personal trainer must be well versed in - answer biomechanics, nutrition, joint
structure, kinesiology
a personal trainer is - answer a empathetic teacher of the movement and functions who
professionally motivates, plans, monitors
3 methods of teaching fitness - answer visual, auditory, kinesthetic
gym etiquette - answer wipe down, let people work in, no weights in stretching area,
keep weight room clear of loose objects
the cell produces what - answerATP (adenosine triphosphate)
3 energy systems - answerATP, glycolysis, aerobic oxidation
ATP/creatine = - answerthe body's immediate energy system. helps physical work that
lasts 1-10 seconds
use of creatine phosphate - answercombines with ADP to immediately replenish ATP
use of glycolysis - answerwhen physical movement is form 10 secs-3mins
what is the glycolytic system - answerbreakdown of carbs to pyruvate/lactate
what happens when you need more oxygen than when you have - answerpyruvate is
converted to lactate
pathway to produce ATP is called what - answeraerobic oxidation
kreb's cycle - answermetabolic process of hydrogens being removed from 4 molecules
2 components of a muscle - answeractive contractile component - produces
tension/shortens muscles
passive non-contractile component - tendons, connective tissue, ligaments
3 types of connective tissue - answersurrounding muscle fiber - endomysium
muscle fiber cell membrane - sarcolemma
, surrounds fasciculis - perimysium
groups of muscle fibers - answerfasciculi
The entire muscle is surrounded by - answerepimysium
skeletal muscle fibers contains hundreds-thousands of what - answermyofibrillae
what is a myofibril - answersmallest unit of a muscle cell and is composed of 2
myofilaments
What is a myofilament? - answera thick filament of myosin and a thin filament of actin
crossbridges - answerwhen myosin heads attach to actin
3 proteins of actin - answeractin, tropomyosin, troponin
3 muscle tissues - answerskeletal, cardiac, visceral
2 main muscle fibers - answerslow/fast twitch
slow twitch fibers - answertype 1
oxidative fibers
fatigue resistant
richin capillaries/myoglobin
red. lots of blood vessels
fast twitch fibers - answertype 2
divided into type lla/llb based on oxidative capacities
dont use oxygen for energy
rich blood supply
type llb - answerlighter in color
aka white muscle fibers
type lla - answerpink muscle fibers
tonic muscles - answerslow twitch
