MVPA QUIZ

Which of the following strategies is the MOST effective in preventing dehydration and overexertion during prolonged physical activity in a hot environment?

• Drinking water only when feeling thirsty and resting after completing the exercise.
  

• Consuming a balanced amount of water and electrolytes before, during, and after activity.
  

• Wearing multiple layers of clothing to increase sweating and reduce body temperature.
  

• Ignoring fatigue and pushing through discomfort to build endurance.

A person experiencing hypothermia during an outdoor activity starts to feel disoriented, fatigued, and has slow reactions. What is the physiological reason behind this condition?

• The body loses too much heat, causing a drop in core temperature, which slows down body functions.
  
  
  

• The body absorbs too much heat, leading to a rapid increase in blood pressure.

• The muscles produce excess lactic acid, causing exhaustion and lack of coordination.

• The heart rate increases drastically, forcing more oxygen to the brain, leading to confusion.

A long-distance runner collapses due to hyperthermia during a marathon. Which of the following interventions should be done FIRST to prevent further damage?

• Provide cold water to drink immediately and encourage the runner to keep moving.

• Remove excess clothing, move the runner to a shaded area, and apply cold compresses.

• Wrap the runner in blankets to prevent sudden changes in body temperature.

• Encourage the runner to stretch and take deep breaths to relieve discomfort.

Which of the following differentiates overexertion from dehydration?



Overexertion occurs only in athletes, whereas dehydration affects only inactive individuals.

• Overexertion is caused by lack of oxygen, while dehydration is due to excessive water intake.

• Overexertion results in muscle failure, whereas dehydration only affects digestion.

• Overexertion is the excessive use of energy leading to fatigue, while dehydration is the excessive loss of body fluids causing imbalance.

• Overexertion occurs only in athletes, whereas dehydration affects only inactive individuals.

A group of students is planning a winter hiking trip. Based on your understanding of hypothermia risks, which of the following comprehensive plans should they implement?

• Wear thick cotton clothes, limit water intake, and move at a fast pace to maintain body heat.

• Use layered clothing with moisture-wicking fabrics, stay hydrated, and take breaks in a warm shelter if needed.

• Wear a single heavy jacket to preserve heat, eat high-sugar foods, and avoid resting to prevent cooling down.

• Avoid drinking water to reduce sweat production and keep body temperature stable.
