Understanding Fatigue and Recovery in Sports

What is the primary cause of fatigue in short explosive events like 100-meter sprints?

• Phosphocreatine depletion

• Dehydration

• Increased core body temperature

• Lactic acid buildup

Which type of recovery is most effective for replenishing PC stores after short explosive events?

• Nutritional recovery

• No recovery needed

• Active recovery

• Passive recovery

What byproduct accumulates from anaerobic glycolysis causing fatigue in medium-duration events?

• Carbon dioxide

• Oxygen

• Phosphocreatine

• Metabolic byproducts

How does active recovery aid in removing metabolic byproducts?

• By redistributing blood flow and oxygen

• By increasing sweat production

• By increasing body temperature

• By reducing blood flow

What is the effect of high metabolic byproducts in the blood during intense physical activity?

• Increased energy production

• Decreased need for oxygen

• Reduced power of muscle contractions

• Enhanced blood flow

What is a major cause of fatigue in long-duration aerobic events?

• Glycogen depletion

• Phosphocreatine depletion

• Hydrogen ion accumulation

• Immediate energy depletion

What role does hydration play in managing fatigue during long endurance events?

• It decreases blood viscosity

• It increases blood viscosity

• It has no effect on fatigue

• It reduces the need for oxygen

What physiological change triggers central fatigue in extreme endurance events?

• Increased blood flow to muscles

• Decreased sweating and increased core body temperature

• Rapid glycogen replenishment

• Decreased metabolic byproduct accumulation

What is the recommended strategy to recover from glycogen depletion after a marathon?

• High GI meal immediately

• Passive recovery

• Avoid hydration

• Active recovery

How much water should be consumed to recover from a 4 kg body weight loss due to sweating?

• 10 liters

• 8 liters

• 6 liters

• 4 liters
