Range of Motion
The extent, usually measured in degrees, through which a joint can move between its fully flexed and fully extended positions.
ROM stands for Range of Motion.
Definition
Range of motion is how far a joint can travel through its available arc of movement. It can be active, produced by the athlete's own muscles, or passive, produced by an external force, and it varies by joint, individual and the demands of the sport.
Adequate range lets athletes reach the positions their sport requires, such as a deep swimming catch, a full tennis backswing or a low squat, while efficient technique makes use of the range available. Range of motion is influenced by joint structure, soft-tissue length and control; this entry describes it educationally and is not flexibility, rehabilitation or medical advice.

Sports science
- Range of motionHow far a joint can travel through its movement — the arc available at a joint, and the foundation of flexibility and mobility.
- Force and powerThe difference between how much force the body can produce and how quickly it can produce it — the mechanics behind strength and explosiveness.
- Motor learningThe process by which practice and experience produce lasting improvements in how well a movement skill can be performed.
- Reaction timeThe short delay between a signal and the start of the movement made in response to it.
- The kinetic chainThe idea that the body’s segments work as a linked chain, passing force from the ground up through the hips, trunk and limbs.
Goals
- Improve mobilityMove your joints more freely and comfortably through their natural range with regular, gentle practice.
- Improve flexibilityLengthen your muscles and widen your range of motion through regular, gentle stretching over time.
- Improve fitnessBuild well-rounded fitness — stamina, strength and more — through regular, varied activity you can keep up.
- DisciplineBuild consistency, focus and self-discipline through the routines that sport and training encourage.
- TeamworkDevelop cooperation, communication and trust by playing sports that rely on working together.
Practice & sessions
Recovery
- Gentle mobilityGentle mobility work means moving your joints smoothly through a comfortable range to help you feel loose and move well.
- Easy daysEasy days are deliberately gentle training days that keep the effort low so harder sessions can stay hard.
- Rest daysRest days are planned days off from training that give the body and mind time to recover between harder sessions.
Training methods
- Mobility TrainingMobility training works on moving your joints actively through their full range, combining control and flexibility so movement feels free and easy.
- Flexibility TrainingFlexibility training uses stretching to gradually improve how far your muscles and joints can comfortably lengthen and move.
- Endurance Base TrainingEndurance base training is an extended phase of mostly easy, steady aerobic work that lays the aerobic foundation the rest of a training plan builds on.
Physical qualities
- FlexibilityThe range of movement available at a joint or group of joints.
- MobilityUsing a joint’s range of movement actively, with control and strength throughout.
- SpeedHow quickly you can move your body or a part of it from one point to another.
- Muscular strengthHow much force your muscles can produce in a single effort.
- Core stabilityThe ability of the muscles around your trunk to keep it stable while your limbs move.
