First Aid - Types of Injuries
What type of injury is caused by repeated stress over time rather than one sudden impact?
Overuse Injury
Which body system is responsible for pumping blood around the body?
Circulatory System
How can dehydration be prevented during physical activity?
By maintaining regular fluid intake before, during, and after exercise, taking scheduled drink breaks, and replacing fluids lost through sweat to keep the body hydrated and functioning properly.
Where must the line of gravity fall for a person to stay balanced?
Within the base of support
What does “bio” mean in biomechanics?
Which type of injury occurs when force is applied directly to the body, such as being hit during a tackle?
Direct Injury
Which body system allows the body to move using muscles attached to bones?
Muscular System
How does inefficient movement increase injury risk?
It places extra stress on muscles and joints.
What are two disadvantages of having a very wide base of support in sport?
It can reduce speed and agility, and it can make movement less efficient for skills like sprinting, jumping, or changing direction.
What is linear motion?
Movement in a straight line
Identify two signs or symptoms of dehydration during physical activity.
Dizziness, fatigue, headache, dry mouth, muscle cramps (any two)
What is the role of white blood cells in the body?
White blood cells protect the body by identifying and destroying bacteria and viruses to prevent infection.
What is the term for when all forces acting on the body are balanced?
Equalibrium
Name the two main types of balance used in sport.
Static balance and dynamic balance.
What is angular motion and provide an example.
Movement around a joint or axis, such as a kick, throw, or bicep curl.
Explain how inefficient movement can increase the risk of injury during sport or exercise.
Inefficient movement places extra stress on muscles and joints, leading to poor technique, fatigue, and a higher risk of injuries such as strains or overuse injuries.
What is the role of haemoglobin in the body?
Haemoglobin is a protein in red blood cells that carries oxygen from the lungs to working muscles.
A gymnast lands awkwardly after a vault and twists their ankle. The ankle becomes swollen and painful.
Soft tissue injury + indirect injury
How the base of support affect stability in sport.
A wider base of support increases stability, while a narrower base of support decreases stability.
Explain the difference between speed and velocity.
Speed is how fast something moves, while velocity is how fast something moves in a specific direction.
Compare a soft tissue injury and a hard tissue injury using one sporting example for each.
A soft tissue injury affects muscles, ligaments, or tendons (e.g. hamstring strain), while a hard tissue injury affects bones (e.g. fractured wrist).
During intense exercise, how do the circulatory and respiratory systems work together to help performance?
The respiratory system brings oxygen into the lungs, while the circulatory system transports oxygen-rich blood to working muscles to help produce energy and remove waste products like carbon dioxide.
Analyse how an athlete can improve stability in a dynamic sport situation.
By lowering centre of gravity, widening base of support, and controlling movement.
Explain how centre of gravity, base of support, and line of gravity work together to affect performance in sport.
A lower centre of gravity and a wider base of support increase stability. The line of gravity must fall within the base of support to maintain balance. If it moves outside, the athlete loses balance and stability.
Explain how velocity changes during a rugby tackle.
The player’s velocity decreases rapidly due to contact and opposing force.
