NSCA Test (Chapter 1, 2, 4, 5, 6, 10)
To which of the following structures do the cross-bridges attach during muscle action? - ANS -
Actin
When throwing a baseball, an athlete's arm is rapidly stretched just prior to throwing the ball.
Which of the following structures detects and responds to that stretch by reflexively increasing
muscle activity? - ANS - Muscle spindle
Which of the occurs during the QRS complex of a typical ECG?
i. Depolarization of the atrium
ii. Repolarization of the atrium
Iii. Repolarization of the ventricle
Iv. Depolarization of the ventricle - ANS - ii & iv only
Which of the following will lengthen the I-bands of the sarcomeres within the biceps brachii
muscle? - ANS - Downward movement phase of the triceps pushdown
The production of lactic acid results from the activation of which of the following energy
systems? - ANS - Fast Glycolysis
A female professional basketball player is using interval training during preseason conditioning
to prepare for the upcoming season. Which of the following exercise interval duration and
intensity combinations will MOST effectively stimulate the metabolic demands of a basketball
game? - ANS - 10 seconds / 95%
Decreasing which of the following variables will, with training, cause an increase in the capacity
of the lactic acid energy system to produce ATP - ANS - Rest period
As an athlete maintains exercise at near-maximal intensity, which of the following will
accumulate in the working muscle? - ANS - Hydrogen ions
During the upward movement phase of the push press exercise the: - ANS - Quadriceps muscles
are agonists, and the triceps brachii and anterior deltoids are agonists.
During the upward movement phase of the front squat exercise - ANS - the illiopsoas acts as an
antagonist to the concentric movement.
A synergist is indirectly contributing to the movement, therefore, - ANS - the biceps femoris is
acting synergistically during the upward movement of the low bar back squat.
The approximate torque capability of eccentric muscle actions as compared to concentric muscle
actions would be - ANS - 120% greater in eccentric muscle actions.
An injured athlete is directed by the team physician to avoid exercises that involve lumbar
extension. Before the injury, the athlete was performing both the lying supine leg lift and the
abdominal crunch exercise - ANS - The Strength and Conditioning professional should
discontinue the Lying supine leg lift.
Which of the following exercises stimulates the greatest increase in axial skeleton bone mineral
density? - ANS - Shoulder press
Which of the following components of mechanical loads is the least important for stimulating
new bone formation? - ANS - Rest Period
Which of the following increases as an adaptation to chronic resistance training but decreases as
an adaptation to chronic aerobic training? - ANS - Maximal power production
An 18-year-old rugby player is starting his first periodized resistance training program in a
collegiate strength and conditioning facility. The strength and conditioning professional
conducted strength testing every 6 weeks with the following results for the 1RM bench press
exercise. Which of the following neuromuscular adaptations is primarily responsible for the
increases in strength from week 6 to week 18? - ANS - Muscle fiber hypertrophy
Which of the following cardiovascular responses is disproportionately high during a set of
resistance training exercise as compared to during an aerobic exercise session? - ANS - Heart
rate
All of the following are potential indicators of overtraining except: - ANS - (Under
Cardiovascular Responses) Decreased exercise HR: Greater volumes of training affect heart rate.
Exercise-induced maximum heart rates decrease from overtraining, as have heart rates at
absolute submaximal exercise intensities
A freshman collegiate 1600-meter runner, who has been aerobically training for 2 years,
increases her performance time throughout the course of her first season on the track team.
Which of the following physiological responses is primarily responsible for her performance
increases? - ANS - Increase in running economy: As the intensity of exercise increases, the
oxygen consumption rises to maximal levels. When oxygen consumption can no longer increase
to meet the demands, maximal oxygen uptake has been achieved
Which of the following cardiovascular response is disproportionately high during a set of
resistance training exercise as compared to during an aerobic exercise session - ANS - Heart
Rate: The rate of increase in heart rate of increase in heart rate, the actual acute heart rate
response, and maximal heart rate achieved relate to a variety of individual characteristics of the
human system, including fitness and age, in addition to exercise workload
Which of the following is most significant adaption to chronic resistance training for an older
adult? - ANS - Resistance exercises are most beneficial for older populations who need to
enhance musculoskeletal strength, power, muscle mass, bone mineral density and functional
abilities
The parent of a child informs the strength and conditioning professional that her child has been
placed in Stage I of Tanner's classification. What does this classification assess? - ANS -
Biological age can be measured in terms of skeletal years; children can be the same
chronological age but differ several years in biological age
A 12-year old male has been resistance training twice weekly for six weeks. Which of the
following adaptions contribute the most to training-induced strength gains? - ANS - Neurological
factors as opposed to hypertrophic factors are primarily responsible for strength gains
A 165- pound (75 kg) athlete has an average daily intake of 450 grams of carbohydrate, 75 grams
of protein, and 100 grams of fat. What percentage of the total kilocalorie intake is carbohydrate?
- ANS - 60
A 115 pound (61 kg) softball player has an average daily nutrient intake of 325 grams of
carbohydrate, 55 grams of protein, and 75 grams of fat. Approximately what percent of her total
caloric intake is protein? - ANS - 10%
A member of the cross country team has become withdrawn and her teammates notice she is
increasingly more concerned about her weight. Which of the following additional behaviors are
warning signs or symptoms that may indicate an eating disorder?
i: She selects only healthy foods to eat
ii: She occasionally misses her menstrual cycle
iii: She appears to have lost a significant amount of weight
iv: When asked she denies that she has an eating disorder - ANS - B: III and IV only
