Which list contains only factors that negatively affect physical fitness?

• A. Injury, poor sleep, and lack of physical activity
• B. Injury, good sleep, and lack of physical activity
• C. Injury prevention, poor sleep, and lack of physical activity
• D. Injury, poor sleep, and adequate physical activity

Answer: (A)

Focusing on what hurts physical fitness, the combination of injury, poor sleep, and lack of physical activity includes clear negative influences. Injury can interrupt training, lead to time away from workouts, and cause lasting decreases in performance. Poor sleep impairs recovery, decision-making, and energy levels, all of which lessen workout quality and progress. Not getting enough physical activity means less stimulus for the heart, muscles, and lungs, resulting in a decline across endurance, strength, and flexibility.

The other options mix in factors that support or protect fitness—such as good sleep, injury prevention, and adequate activity—so they don’t consist solely of negative influences.
