What is a lever?

A simple machine that uses a rigid bar to pivot around a point (fulcrum) to move a load with an applied effort.

What is a third class lever?

A lever where the force is located between the axis and the resistance or load to be moved.

Agonist

The agonist in kicking is the quadriceps, which are the primary movers straightening the knee during the kicking motion.

Antagonist

The hamstrings act as opposing muscles, controlling and balancing the movement by resisting excessive force.

What are stabilisers in kicking?

Muscles like the gluteus maximus, core muscles, and calves that help maintain balance and control throughout the kicking action.

What is the purpose of warming up?

To prepare the body both physiologically and psychologically for the training session that follows.

What are the physiological benefits of warming up?

Increases heart rate, blood flow, muscle elasticity, and enzyme activity to enhance oxygen delivery, energy release, and muscle readiness.

What does rehabilitation involve?

The process of returning to optimal functioning and reducing the chance of re-injury through tailored recovery programs.

How do resistance exercises benefit joints?

They strengthen muscles which supports joints by improving their stability and alignment during movement, reducing stress and risk of injury.

Dynamic stretching vs Static stretching

Dynamic stretching involves active movements to warm up muscles, while static stretching involves holding a muscle in an extended position to increase flexibility.

What are Type 1 muscle fibres?

Slow-twitch oxidative muscle fibres that are resistant to fatigue and have a high capacity to generate ATP by oxidative metabolic processes.

What is the all-or-nothing principle?

A muscle fibre either contracts fully or not at all when the stimulus reaches the required threshold, with no partial contraction.

What is carbohydrate loading?

A method of manipulating training and nutrition to maximize muscle glycogen stores for endurance events.

What is plyometric training?

Training aimed at increasing muscular power by first stretching a muscle then contracting it in the shortest time possible.
