2. Describe the significance of increased red blood cell volume in relation to
exercise training.
Increased red blood cell volume enhances oxygen transport to
muscles, improving endurance and performance during exercise.
Increased red blood cell volume has no effect on exercise
performance.
Increased red blood cell volume leads to higher body fat
accumulation.
Increased red blood cell volume decreases the risk of injury during
exercise.
3. Describe the significance of the client's body fat percentage change over

chronic aerobic training increases it.
Chronic resistance training and chronic aerobic training both
increase mitochondrial density.
Chronic resistance training increases mitochondrial density, while
chronic aerobic training decreases it.
9. If a client is consistently rising from the seat during the concentric phase of
