VO2 max

The greatest volume of oxygen a person can take up and use per minute during hard whole-body exercise, usually expressed in millilitres per kilogram per minute.

Related: Cardiovascular endurance, Steady state
Lactic acid system

The energy pathway that breaks down glucose without oxygen to release energy quickly, producing lactate and lasting roughly ten seconds to two minutes of hard effort.

Related: Anaerobic threshold, Phosphagen system
Phosphagen system

The immediate energy pathway that rebuilds ATP from creatine phosphate stored in muscle, supplying very short bursts of maximal power lasting up to about ten seconds.

Related: Lactic acid system, ATP
Aerobic system

The energy pathway that uses oxygen to break down carbohydrate and fat for ATP, supplying sustained energy for longer, lower-intensity activity.

Related: VO2 max, Steady state
ATP

Adenosine triphosphate, the molecule that stores and releases energy in muscle cells; splitting off one phosphate group powers muscle contraction.

Related: Phosphagen system, Aerobic system
Anaerobic threshold

The exercise intensity at which lactate begins to accumulate faster than it can be cleared, marking the point where hard effort can no longer be sustained for long.

Related: Lactic acid system, Lactate
Lactate

A by-product formed when glucose is broken down without oxygen; it can be used as fuel by other muscles and the heart once oxygen is available.

Related: Anaerobic threshold, Lactic acid system
Steady state

A condition during submaximal exercise where oxygen uptake and heart rate level off and energy demand is met aerobically, allowing work to continue for a long time.

Related: VO2 max, Aerobic system
Cardiovascular endurance

The ability of the heart, blood vessels and lungs to deliver oxygen to working muscles over prolonged activity; often assessed through a timed run or shuttle test.

Related: VO2 max, Muscular endurance
Muscular endurance

The capacity of a muscle or muscle group to perform repeated contractions against a moderate load without tiring quickly.

Related: Cardiovascular endurance, Muscular strength
Muscular strength

The maximum force a muscle or muscle group can produce in a single maximal effort, such as one repetition of a heavy lift.

Related: Muscular endurance, Power
Power

The rate at which force is applied, calculated as work done divided by time taken; it combines strength and speed in explosive actions such as jumping or throwing.

Related: Muscular strength, Speed
Speed

The ability to move the body or a body part from one point to another in the shortest possible time.

Related: Power, Agility
Agility

The ability to change direction quickly and accurately while maintaining balance and control of the body.

Related: Speed, Balance
Flexibility

The range of movement available at a joint or group of joints, influenced by muscle length, joint structure and connective tissue.

Related: Static stretching, Dynamic stretching
Balance

The ability to keep the body's centre of gravity over its base of support, whether stationary or while moving.

Related: Agility, Coordination
Coordination

The ability to use body parts together smoothly and efficiently to produce accurate, controlled movement.

Related: Balance, Skill acquisition
Body composition

The relative proportions of fat mass and lean mass, such as muscle, bone and organs, that make up a person's body.

Related: Muscular strength, Cardiovascular endurance
Warm-up

A preparatory phase of light activity and movement drills that raises body temperature, increases blood flow and prepares muscles and joints for the main session.

Related: Dynamic stretching, Cool-down
Cool-down

Gentle activity and stretching performed after exercise to help heart rate and body temperature return gradually to resting levels and to reduce stiffness.

Related: Warm-up, Static stretching
Static stretching

Holding a muscle in a lengthened position for a set period, usually performed after activity to improve flexibility and reduce muscle tension.

Related: Flexibility, Dynamic stretching
Dynamic stretching

Controlled movements through a joint's full range performed before activity to raise muscle temperature and prepare the body for action.

Related: Warm-up, Static stretching
Progressive overload

Gradually increasing the demand placed on the body during training so that adaptation continues without causing injury or overtraining.

Related: Specificity, Recovery
Specificity

The training principle that adaptations are specific to the type of exercise performed, so training must closely match the demands of the target activity.

Related: Progressive overload, Periodisation
Periodisation

Organising training into planned phases across a season or year, varying volume and intensity to peak for key competitions and allow recovery.

Related: Progressive overload, Tapering
Tapering

A planned reduction in training volume before competition that allows fatigue to dissipate while fitness is retained, aiming to maximise performance on the day.

Related: Periodisation, Recovery
Recovery

The period and practices, such as sleep, nutrition and light activity, that allow the body to repair and adapt after training stress.

Related: Progressive overload, Overtraining
Overtraining

A prolonged state of fatigue and underperformance caused by training loads that exceed the body's ability to recover, often with disturbed sleep and mood.

Related: Recovery, Periodisation
Skill acquisition

The process by which a learner develops and refines movement skills through practice, feedback and experience, moving from awkward to automatic performance.

Related: Motor skill, Feedback
Motor skill

A learned movement pattern with a clear goal that requires coordination of the body and improves with practice, such as a tennis serve.

Related: Skill acquisition, Feedback
Feedback

Information a performer receives about a movement, either from their own senses or from an external source such as a coach, used to adjust and improve future attempts.

Related: Skill acquisition, Motor skill
Biomechanics

The study of forces and motion applied to the human body, used to analyse and improve the efficiency and safety of sporting technique.

Related: Lever, Centre of gravity
Lever

A rigid structure such as a bone that rotates about a pivot when force is applied, allowing the body to produce and control movement.

Related: Biomechanics, Torque
Torque

The turning effect of a force about a pivot, calculated as force multiplied by the perpendicular distance from the pivot to the line of action.

Related: Lever, Centre of gravity
Centre of gravity

The point at which the body's weight is considered to act; keeping this point over the base of support helps maintain stability.

Related: Balance, Biomechanics
Projectile motion

The curved path followed by an object or body launched into the air, shaped by release angle, release speed and gravity.

Related: Biomechanics, Centre of gravity
Sports psychology

The study of how thoughts, emotions and behaviour influence participation and performance in physical activity, including motivation, arousal and anxiety.

Related: Arousal, Motivation
Arousal

The level of physical and mental activation a performer experiences, ranging from drowsy to highly excited, which can help or hinder performance depending on the task.

Related: Sports psychology, Anxiety
Motivation

The drive that energises and directs behaviour toward a goal, which may come from internal satisfaction or from external rewards.

Related: Sports psychology, Goal setting
Goal setting

A planning technique in which specific, measurable and achievable targets are set to focus effort, track progress and build confidence.
