What is central fatigue primarily associated with?

Muscle fibre depletion

Neural transmission in the brain

Lactic acid build-up

Dehydration

Answer explanation

Central fatigue is primarily linked to neural transmission in the brain, affecting the communication between the brain and muscles, rather than muscle fiber depletion, lactic acid build-up, or dehydration.

Ava is training for a marathon and notices that she feels extremely tired during her long runs. Which of the following is a common cause of peripheral fatigue?

Reduced motivation

Decreased muscle glycogen

Increased serotonin levels

Mental stress

Answer explanation

Decreased muscle glycogen is a common cause of peripheral fatigue as it directly affects energy availability for muscle contractions, leading to fatigue during prolonged exercise.

During a long-distance race, how might central fatigue impact Arjun's physical performance?

By increasing muscle strength

By reducing cognitive function

By impairing motor coordination

By enhancing endurance

Answer explanation

Central fatigue impairs motor coordination, leading to decreased physical performance. This affects the ability to execute movements effectively, which is crucial for athletic performance.

Which mechanism is NOT typically involved in peripheral fatigue?

Accumulation of metabolic by-products

Depletion of neurotransmitters

Muscle fibre damage

Reduced blood flow to muscles

Answer explanation

Depletion of neurotransmitters is primarily associated with central fatigue, not peripheral fatigue. Peripheral fatigue typically involves metabolic by-products, muscle damage, and reduced blood flow.

What is a common symptom of mental fatigue?

Increased physical strength

Enhanced concentration

Decreased alertness

Improved memory

Answer explanation

Decreased alertness is a common symptom of mental fatigue, as it reflects the brain's reduced ability to focus and respond effectively. In contrast, increased strength, enhanced concentration, and improved memory are not associated with mental fatigue.

How can fatigue increase the risk of injury?

By improving reaction time

By enhancing muscle flexibility

By reducing coordination and focus

By increasing energy levels

Answer explanation

Fatigue impairs coordination and focus, making it harder to react appropriately to situations. This increases the likelihood of accidents and injuries, as the body cannot respond effectively to demands.

Which of the following is a method to recover from fatigue?

Continuous exercise without breaks

Adequate rest and sleep

Increased caffeine intake

Ignoring the symptoms

Answer explanation

Adequate rest and sleep are essential for recovery from fatigue, as they allow the body to repair and rejuvenate. Continuous exercise, increased caffeine, and ignoring symptoms can worsen fatigue.
