Lecture 2 Development Of Muscular Strength, Anaerobic Capacity And Power In Children

Question 1

Which of the following statements most accurately describes the factors involved in the development of muscular strength in children?
a) Strength gains in children are due to muscular
enlargement alone.
b) Size-dependent and size-independent factors influence
the development of muscular strength in children.
c) Strength gains in children are not related to increases in
muscle cross-sectional area.
d) Children are more susceptible to muscle damage and
delayed onset muscle soreness (DOMS) than adults.

Answer 1

b) Size-dependent and size-independent factors influence

the development of muscular strength in children.

Question 2

According to Dotan et al. (2012), the gradual increase in motor neuron impulse frequency during childhood
may be responsible for what?
a) An increase in utilisation of type Il motor units and
transformation of type I to type II fibres during growth.
b) An increase in utilisation of type I motor units and
transformation of type Il to type I fibres during growth.
c) Deterioration of type Il fibres during growth.
d) Transformation of type Ilb to type Ila fibres.

Answer 2

a) An increase in utilisation of type Il motor units and

transformation of type I to type II fibres during growth.

Question 3

How does nerve conduction velocity change during
childhood?
a) It increases in the lower limbs and decreases in the upper
limbs
b) It decreases in the lower limbs but increases in the
upper limbs
c) It increases in both the upper and lower limbs
d) It decreases in both the upper and lower limbs

Answer 3

b) It decreases in the lower limbs but increases in the

upper limbs

Question 4

Which of the following statements is false?
a) Most habitual activity in children consists of short-burst
activities lasting less than 15 seconds
b) Sprint performance relative to body mass decreases as
children age.
c) Improvements in short burst field activities in children,
such as sprints, are related to
mechanical, neuromuscular and anthropometric factors.
d) Anaerobic capacity determined by the Wingate test is a
good predictor of sprint performance in children.

Answer 4

d) Anaerobic capacity determined by the Wingate test is a

good predictor of sprint performance in children.

Question 5

Online activity content: According to Ozmun et al.
(1994), strength gains following resistance training in
prepubescent children are attributed to:
a) hypertrophy
b) Increased muscle activity (neurological
mechanisms)
c) hypertrophy and neurological mechanisms
d) nothing - children do not experience strength gains
following resistance training

Answer 5

b) Increased muscle activity (neurological

mechanisms)

Question 6

Which of the following, in relation to dimensional theory, is not a factor that
may contribute to a higher scaling of exponent of strength compared to
height in children?

A) lower number of motor units
B) muscle length
C) muscle architecture
D) motor unit type

Answer 6

A) lower number of motor units
