Strength and Conditioning Final Exam
Questions & Answers(RATED A+)
sliding-filament theory - ANSWERActin filaments at each end of the sarcomere slide inward on
myosin filaments, pulling the z-lines toward the center of the sarcomere and thus contracting the
muscle fiber.
motor unit - ANSWERa motor neuron and the muscle fibers it innervates
proprioceptors - ANSWERspecialized sensory receptors that provide the central nervous system w/
information needed to maintain muscle tone and perform complex coordinated movements.
bodily awareness of kinesthetics
muscle fiber types and uses - ANSWERtype I = slow twitch
type IIa = fast twitch; muscular endurance -> middle distance runner
type IIb = fast twitch; explosive and powerful
role of nutritionist - ANSWERpersonalized nutritional counseling
dietary analysis of food records
nutritional education
referral and treatment of eating disorders
micronutrient - ANSWERnutrients required by the body that it cannot produce itself
macronutrient - ANSWERnutrients that are required in significant amounts in the diet.
3 classes:
proteins
carbohydrates
lipids (fats)
vitamin - ANSWERorganic substance that cannot be synthesized by the body
, mineral - ANSWERthe chemical elements required by living organisms other than the 4 elements
carbon, hydrogen, nitrogen, and oxygen that are present in nearly all organic molecules
Anabolic steroids (definition) - ANSWERthe synthetic derivatives of the male sex hormone,
testosterone
supplements (definition) - ANSWERa product intended for ingestion that includes one of the
following:
a vitamin
a mineral
an herb or other botanical
an amino acid
a dietary substance for use by humans to supplement the diet by increasing total dietary intake
cori cycle (definition) - ANSWERlactate is transported in the blood to the live where it is converted
into glucose
krebs cycle (definition) - ANSWERtakes place in mitochondria. A series of reactions that continue the
oxidation of the substrate begun in glycosis. It's a way we can continue to produce energy.
Minimal essential strain (MES) - ANSWERthe threshold stimulus that initiates new bone formation
approx. 1/10 of the force required to fracture bone
Resting oxygen uptake (MET) - ANSWERestimated at 3.5 mL of oxygen/kg of BW/min. (mL * kg ^-1 *
min. ^ -1)
systolic blood pressure - ANSWERthe pressure exerted against the arterial walls as blood is forcefully
ejected during ventricular contraction.
diastolic blood pressure - ANSWERthe pressure exerted against the arterial walls when no blood is
being forcefully ejected through the vessels
five food groups - ANSWERgrains
