MULTIPLE CHOICE QUESTION
30 sec • 1 pt
The ability to perform daily tasks without fatigue
The maximum strength/power a person can generate
The minimum force necessary to accomplish a task
The endurance level of a person
Answer explanation
Functional reserve refers to the maximum strength or power a person can generate, which is crucial for performing high-intensity tasks. This distinguishes it from endurance or daily task performance.

What primarily accounts for initial strength gains during resistance training?
Increase in muscle mass
Improved cardiovascular efficiency
Neural adaptations
Enhanced flexibility
Answer explanation
Initial strength gains during resistance training are primarily due to neural adaptations. These adaptations improve the efficiency of muscle recruitment and coordination, allowing for greater force production without significant increases in muscle mass.

Which of the following is NOT a neural adaptation to resistance training?
Increased number of motor units recruited
Increased firing rate of motor units
Increased motor unit synchronization
Decreased muscle fiber size
Answer explanation
Decreased muscle fiber size is NOT a neural adaptation; rather, resistance training typically leads to increased muscle fiber size (hypertrophy). The other options reflect neural adaptations that enhance strength.

How does resistance training affect skeletal muscle mass?
Through increased flexibility and endurance
By improving cardiovascular health
Via hyperplasia and hypertrophy
By reducing fat tissue
Answer explanation
Resistance training increases skeletal muscle mass primarily through hypertrophy, which is the enlargement of existing muscle fibers, and hyperplasia, the formation of new muscle fibers.

MULTIPLE CHOICE QUESTION

What is hyperplasia?
The addition of new myofibers (muscle cells).
The growth of existing myofibers.
The increase in muscle proteins.
The increase in cross-bridges.
Answer explanation
Hyperplasia refers to the addition of new myofibers (muscle cells), which increases muscle mass. This is distinct from hypertrophy, which is the growth of existing myofibers.

What is the primary factor that skeletal muscle hypertrophy depends on?
The amount of actin and myosin.
The number of mitochondria.
The level of calcium ions.
The presence of lactic acid.
Answer explanation
Skeletal muscle hypertrophy primarily depends on the amount of actin and myosin, as these proteins are essential for muscle contraction and growth. Increased synthesis of these proteins leads to muscle fiber enlargement.

MULTIPLE CHOICE QUESTION

Which of the following is NOT a signaling event that leads to increases in muscle protein synthesis?
Increased mRNA.
Activation of mTOR.
Increase in ribosomes.
Decrease in ATP.
Answer explanation
Decrease in ATP is NOT a signaling event that promotes muscle protein synthesis. In fact, low ATP levels can hinder energy availability, negatively impacting protein synthesis, unlike increased mRNA, mTOR activation, and ribosome increase.
