ENS Comp Exam Questions And CorrectAnswers Latest Version
Q: What process is being outlined below?
1. Initiation of ATP splitting (by myosin ATPase) causes the myosin head to
be in an "energized) state that allows it to move into position to be able to
form a bond with actin.
2. The release of phosphate from the ATP splitting process then causes the
myosin head to change shape and shift.
3. This pulls the actin filament in toward the center of the sarcomere and is
referred to as the power stroke. ADP is then released.
4. Once the power stroke has occurred, the myosin head detaches from the
actin but only after another ATP binds to the myosin head, because the
biding process facilitates detachment.
5. The myosin head is now ready to bind another actin (as described in step
1), and the cycle continues as long ATP and ATPase are present and calcium
is bound to the troponin. ANS✔✔ A: Muscle contraction-phases
Q: Neural adaptations to strength training include all of the following except:
ANS✔✔ A: Increased sensitivity of the Golgi tendon organ reflex
,Q: How is the acute enhancement of muscle power after performing a
conditioning activity near maximal loading conditions defined? ANS✔✔ A:
Post-activation potentiation
Q: Regarding cluster sets read the statements below and choose the right
option
I) Cluster set can be defined as a set, which there is 15-45 seconds in
between individual repetitions
II) Traditionally cluster sets have been used to improve power output and
velocity of training
III) There are different ways to organize clusters sets and the cluster sets
structures may affect the ability to maximize velocity across the set in
explosive exercises
IV) During cluster sets you should only manipulate the number of repetitions
in the cluster in order to induce specific physiological and performance
response ANS✔✔ A: Statements IV and I are false and statements II and III
are true
Q: Strength training is one of the most widely practiced forms of physical
activity. Strength training is used to enhance athletic performance, augment
musculoskeletal health and alter body aesthetics. Chronic exposure to this
type of activity produces marked increases in muscular strength and power,
which are attributed to a range of neurological and morphological
adaptations. Regarding morphological adaptations read the statements
below and choose the right option:
, I) Typically, strength training causes a shift in muscle fiber proportion from
type IIX to type IIA muscle fiber type.
II) Fast eccentric training might induced fiber splitting which has been
postulated to cause hyperplasia in humans.
III) Hypertrophy is an increase in muscle size due to long-term effects of
strength training inducing a net positive protein balance.
IV) Whole muscle cross sectional area grows more than muscle fiber cross
sectional ar ANS✔✔ A: Statements II and IV are false and statements I, III and
V are true
Q: When relating the season terminology to periodization periods, which
season corresponds to the preparatory period of training? ANS✔✔ A: Off-
season
Q: All of the following are true considering conjugate periodization, except:
ANS✔✔ A: Some training blocks are designed to hammer an athlete with a
particular emphasis.
Q: In regards concurrent training, studies have suggested that a particular
endurance training modality to cause negative effects on muscle
hypertrophy when performed concurrently with strength training. Which
modality demonstrated the smallest gains in lower body hypertrophy?
ANS✔✔ A: Running
Q: When training for increasing power, all of the following factors are
important, except: ANS✔✔ A: It is important to increase a blood lactate
tolerance likewise an efficient muscular buffering system
