1. A student fell during a football match and injured their ankle. What immediate First Aid steps should be taken?
Ans: For an ankle injury, which is a common soft tissue injury, you should immediately apply the R.I.C.E. or PRICE principle.
The steps include:
(i) Protection: Protect the injured area from further damage by using a support or brace.
(ii) Rest: Stop playing or putting pressure on the injured part to prevent further tissue damage and start the healing process.
(iii) Ice: Apply ice wrapped in a cloth for 10–15 minutes every 2 hours to reduce pain and swelling.
(iv) Compression: Wrap the ankle evenly with an elastic bandage to limit swelling and provide support.
(v) Elevation: Keep the injured limb raised above heart level as often as possible to help fluid drain away and reduce swelling.
2. During a sports event, a player becomes unconscious but is breathing. What should you do?
Ans: In this situation, you should follow the DRSABCD Action Plan and the Golden Rules of First Aid:
(i) Check for Danger: Ensure the area is safe for yourself, bystanders, and the unconscious player.
(ii) Call for Help: Send someone to call for medical help immediately (dial 112 for emergency services).
(iii) Airway and Recovery Position: Since the player is breathing, you should check for any airway obstruction. Carefully roll the casualty into the recovery position to keep the airway clear, tilt their head back, and lift the chin.
(iv) Stay with the person: Do not move the person roughly, stay calm, and stay beside them to monitor their condition until professional medical help arrives.
3. What items should be included in a basic First Aid kit?
Ans: According to the visual guide in the sources, a basic First Aid kit should include the following items:
(i) Bandages, Gauze roll, and pads.
(ii) Elastic bandages and Adhesive tape.
(iii) Thermometer.
(iv) Safety pins.
(v) Antiseptic wipes.

Answer in brief:
1. Compare voluntary and involuntary muscles with examples.
Ans: Voluntary muscles (Skeletal Muscles) are attached to bones and consciously control the movement of body parts. They are long, cylindrical, and striated (e.g., biceps, quadriceps, deltoids).
Involuntary muscles (Smooth Muscles) are found in the walls of hollow internal organs and regulate involuntary functions without our conscious control. They are spindle-shaped and non-striated (e.g., muscles in the stomach, blood vessels, intestines).
2. What happens to muscles when you exercise regularly?
Ans: When you exercise regularly, your muscles experience long-term adaptations. They increase in size, strength, and endurance. Additionally, your body grows new capillaries in your muscles—a process called capillarisation—which helps improve endurance.
3. What changes occur in breathing and pulse rate when you run compared to when you rest?
Ans: At rest, a normal breathing rate is about 12–15 breaths per minute and the heart rate is about 70–80 beats per minute. When you run, your breathing rate increases to over 40 breaths per minute to take in more oxygen, and your pulse (heart rate) beats 2 to 3 times faster to pump blood more quickly to the active tissues.
4. Design a circuit training to improve cardiorespiratory fitness.
Ans: Based on the activities mentioned in the text, a simple circuit training to improve cardiorespiratory fitness could include:
Station 1: Jumping jacks (for 2 minutes).
Station 2: Running or Jogging (for 3 to 4 minutes).
Station 3: Stair climbing.
Station 4: Cycling.
Station 5: Cool down with Anuloma-viloma (breathing exercise).
5. “Growth stops after a certain age, but development continues throughout life.” Explain the statement.
Ans: Growth refers to the measurable, quantitative structural and physical changes in the body (like increases in height and weight), and this process stops after maturity is attained. Development, however, is a wider term that includes overall qualitative changes in functioning, skills, and behaviour, which can continue to improve and evolve throughout a person’s entire life.
6. How can lack of sleep affect growth and development?
Ans: According to the cultural and lifestyle factors affecting the body, lifestyle choices such as sleep, rest, and activity directly affect hormonal cycles and the speed of maturation. Therefore, a lack of sleep can disrupt these hormonal cycles and negatively impact the timely biological maturation and development of the body.
