Strength Adaptations Quiz

What is a primary neural adaptation from strength training?

• Decreased muscle mass

• Increased ATP production

• Increased recruitment of FG and FOG fiber types

• Decreased anaerobic threshold

How does strength training contribute to the reduction of injury risk?

• Decreases inhibition of stretch reflex

• Increases muscle hyperplasia

• Increases strength of tendons and ligaments/bone density

• Delays OBLA

What is the effect of strength training on muscle mass and metabolism?

• Decreased muscle mass and decreased metabolism

• Increased muscle mass and increased metabolism

• Increased muscle mass and decreased metabolism

• Decreased muscle mass and increased metabolism

What is a structural adaptation of neural pathways in response to strength training?

• Increased speed and power output

• Increased force of contraction

• Decreased inhibition of the stretch reflex

• Increased recruitment of motor units and FG and FOG fibre types

What is the functional effect of decreased inhibition of the stretch reflex due to strength training?

• Increased force of contraction from the antagonist muscle

• Improved co-ordination and simultaneous stimulation of motor units

• Increased stretch of the antagonist

• Decreased force of contraction

What overall effect on performance is achieved through the physiological adaptations made by neural pathways to strength training?

• Decreased speed, strength, and power output

• Increased speed, strength, and power output

• Decreased coordination and motor unit stimulation

• Increased inhibition of muscle reflexes

What does muscle hypertrophy refer to?

• Decrease in muscle cell size

• Increase in muscle cell size

• Increase in number of muscle fibers

• Decrease in number of muscle fibers

What is muscle hyperplasia characterized by?

• Increase in muscle cell size

• Decrease in muscle cell size

• Increase in number of muscle fibers

• Decrease in number of muscle fibers

What are actin-myosin filaments?

• Lipids that store energy in muscle cells

• Carbohydrates that fuel muscle contractions

• Proteins that form the contractile units of skeletal muscle

• Nucleic acids that transmit genetic information in muscle cells

What is the result of muscle hypertrophy as mentioned in the tables of adaptations?

• Decreased muscle mass

• 20-45% increase in cross-sectional area

• Reduced number of myofibrils

• Decreased protein synthesis
