8.6 Knowledge Check

1. What is the primary difference between muscular strength and muscular endurance?

• Strength involves more repetitions; endurance involves more weight
• Strength involves fast-twitch fibres; endurance involves slow-twitch fibres
• Strength uses aerobic systems; endurance uses anaerobic systems
• Endurance improves neuromuscular efficiency; strength improves metabolic activity

2. Which of the following best describes a correct plank position?

• Back arched, elbows extended, neck relaxed
• Head flexed forward, hands wide, body sagging
• Neutral spine, forearms under shoulders, controlled isometric hold
• Lower back rounded, glutes tight, shoulders elevated

6. During a pull-down or pull-up, which muscle is the primary agonist?

• Pectoralis Major
• Deltoids
• Biceps Brachii
• Latissimus Dorsi

7. What is one benefit of performing supersets with antagonistic muscle groups?

• It increases rest time between sets
• It lowers overall workout volume
• It saves time and increases cardiorespiratory output
• It reduces fatigue in both muscle groups
