IEE 380 FINAL PAPER WITH COMPLETE
SOLUTIONS
◉ Imposed demands.
Answer: Adaptations are specific to the:
◉ Low-threshold motor units are recruited first and have lower
force capabilities than higher-threshold motor units.
Answer: Size principle:
◉ Activated.
Answer: Adaptations only occur in muscle fibers that are:
◉ Neural adaptations.
Answer: Source of strength gains from RT in the first 8-10 weeks:
◉ Muscular adaptations.
Answer: Source of strength gains from RT in after 10 weeks:
◉ Young men.
Answer: Greatest strength gains in:
,◉ 40%.
Answer: Mean strength increases in untrained participants:
◉ 20%.
Answer: Mean strength increases in moderately trained participants:
◉ 16%.
Answer: Mean strength increases in trained participants:
◉ 10%.
Answer: Mean strength increases in advanced participants:
◉ 2%.
Answer: Mean strength increases in elite participants:
◉ Heavier loads.
Answer: Most effective for fiber recruitment:
◉ Type of exercise used, its intensity, and its volume.
Answer: The effects of training are related to the:
,◉ Cannot; plasticity.
Answer: Strength enhancement __________ occur without neural
adaptations via _________
◉ Higher brain centers; individual muscle fibers.
Answer: Anaerobic training may elicit adaptations along the
neuromuscular chain, beginning in the _____________________________ and
continuing down to the level of ___________________________
◉ Activation of prime movers
Improved coactivation of the synergists
Reduced coactivation of the antagonists
Neuromuscular reflex potentiation (↑ rate of force development)
Increase neuromuscular junction area.
Answer: Neural adaptations caused by resistance training is due to
an:
◉ Increase in neural drive
Increased motor unit firing frequency (rate coding)
Enhanced motor unit synchronization (recruiting motor units at
same moment)
, Increased motoneuron excitability (more ACh, more excitatory
neurotransmitters, less inhibitory neurotransmitters)
Down regulation of inhibitory pathways (Golgi tendon organ).
Answer: Neural adaptations caused by resistance training from
activation of prime movers is increased via:
◉ = ↑ motor units firing, ↑ synergists muscles, ↑ firing sync.
Answer: ↑ Neural drive =
◉ Motor units are recruited in a sequential order by their size to
produce high levels of force.
Answer: With heavy resistance training, all muscle fibers get larger
b/c:
◉ Recruiting larger ones first to promote great power or speed in a
movement.
Answer: In advanced lifters, the CNS may adapt by allowing
recruitment in non-consecutive order, by:
◉ Increasing its size
