Question 01

What specific function do the these quad roller skate components do: 'Plate, Trucks, Cushions, Bearings and Axle'. Check the relevant box.

Refer to the "Anatomy of a Quad Roller Skate" section in Module 2. Think about the role each component plays — what would fail if it wasn't there?

Guidance

Work through each component in order — Plate, Trucks, Cushions, Bearings, Axle. Consider what each one connects, controls, or enables. Only one answer correctly describes all five.

The plate attaches the boot to the skate hardware, the trucks allow steering and support the wheels, the cushions provide flexibility and control during turning, the bearings reduce friction so wheels spin smoothly, and the axle holds the wheels securely in place. The plate provides braking power, the trucks absorb shock, the cushions increase wheel speed, the bearings hold the wheels in place, and the axle controls foot positioning. The plate allows steering, the trucks create grip, the cushions connect the boot to the plate, the bearings stop wheel wobble, and the axle acts as a brake. The plate increases wheel speed, the trucks secure the boot to the foot, the cushions prevent wheel wear, the bearings absorb impact, and the axle controls balance. The plate provides ankle support, the trucks generate momentum, the cushions lock the wheels, the bearings connect the trucks to the plate, and the axle reduces friction. The plate is used only for mounting toe stops, the trucks hold the bearings, the cushions support the ankle, the bearings absorb shock, and the axle adjusts skate sizing. The plate cushions landings, the trucks act as brakes, the cushions increase speed, the bearings provide grip, and the axle controls turning independently. The plate is responsible for wheel rotation, the trucks support the boot lining, the cushions secure the bearings, the bearings connect to the toe stop, and the axle provides ankle stability.

What does 'Wheel Durometer' mean?

The durometer section in Module 2 defines exactly what this measurement refers to. It is a specific physical property of the wheel material — not its size, weight or colour.

Guidance

Think about what the 'A' scale measures and how it affects grip, speed, and vibration on different surfaces. The answer relates to a core physical property of the wheel material itself.

Durometer measures wheel hardness. Durometer measures wheel size. Durometer measures bearing quality. Durometer measures wheel weight. Durometer measures the amount of wheel rebound. Durometer measures wheel colour. Durometer measures axle strength. Durometer measures wheel width.

List the three mechanisms by which protective gear works to reduce injury from impact. Then identify three specific examples of when PPE worn during a RollerFitness session could be more of a hazard than a benefit.

The three mechanisms are explicitly described in your manual. For the hazard examples — think about range of movement, fit and maintenance status. The manual gives example scenarios.

Suggested structure

Mechanism 1 — how PPE works: Mechanism 2: Mechanism 3: Example where PPE becomes a hazard 1: Example 2: Example 3:

Question 04

Describe the correct technique for breaking a fall in roller skates.

The "How to Break a Fall" section in Module 2 lists the correct steps in order. Focus on centre of gravity and what the first priority is when a fall begins.

Guidance

Think about why lowering your centre of gravity is always the first step. Consider which body parts are most vulnerable on impact and how the correct technique distributes force away from them.

Lean backward to lower your centre of gravity, and reach out behind you with both hands to catch yourself on your palms. Drop low to reduce the centre of gravity and the height of the fall. Try to stay completely upright, stiffen your legs, and roll through the fall by twisting your torso to the side. Tuck your chin to your chest, lock your elbows straight out in front of you, and absorb the full force directly through your wrists. Dive forward into a forward roll over your shoulder, keeping your feet high in the air to prevent the wheels from touching the ground.

Question 05

Explain the clinical difference between a 'Sprain' and a 'Strain'.

The manual covers both definitions with clear clinical language. Focus on which specific structures are damaged in each case — the answer lies in the anatomy, not just the symptoms.

Guidance

Think about what connects bone to bone versus what connects muscle to bone. Both injuries involve overstretching or tearing — but of entirely different tissue types. The correct answer uses the precise anatomical terms from the manual.

A sprain happens over time from overuse, while a strain only happens from a sudden fall. A sprain always requires surgery, while a strain will heal completely with just one day of rest. A sprain is an injury to a ligament (bone to bone), while a strain is an injury to a muscle or tendon (muscle to bone). A sprain is a cracked bone, while a strain is a bruised joint. A sprain only happens in the upper body, while a strain only happens in the lower body.
