Questions and Answers

Which two factors are explored as causes of strength gains?

  • Neural adaptations and hypertrophy (correct)
  • Resistance training and diet
  • Protein synthesis and muscle injury
  • Muscle atrophy and decreased strength

What accounts for most of the early strength gains in subjects who have never lifted weights before?

  • Using advanced training techniques
  • Learning how to produce force effectively (correct)
  • Improving neuromuscular coordination
  • Increasing muscle size through hypertrophy

Which type of training appears to result in greater hypertrophy and strength gains than slower-velocity training?

  • Eccentric training (correct)
  • Concentric training
  • Lower-intensity training
