Sports Injuries and Prevention
Introduction
Sport can build fitness, confidence, teamwork, and enjoyment, but every sport also includes some risk of injury. A sports injury is damage to the body that happens during sport, exercise, or physical activity. Some injuries happen suddenly, while others develop slowly when the same body part is stressed again and again.
This aiMOOC is designed for Grades 7–8. You will learn how common sports injuries happen, how to recognize warning signs, how to lower risk, and what safe actions to take when someone may be injured. The goal is not to diagnose injuries yourself. Your job as a young athlete is to notice problems early, stop when something feels wrong, and tell a responsible adult.
A sudden injury can change a game in seconds. Safe athletes pay attention to pain, surroundings, rules, equipment, and teammates. They also understand that prevention is a shared responsibility between athletes, coaches, families, schools, and health professionals.
Learning Goals
By the end of this course, you should be able to explain the difference between an acute injury and an overuse injury, describe several common sports injuries, connect prevention strategies to the risks they address, identify warning signs that require adult or medical help, and design a realistic injury-prevention plan for a sport you know.
Understanding Sports Injuries
Acute and Overuse Injuries
Acute injuries happen suddenly. Examples include twisting an ankle while landing, colliding with another player, falling on an arm, or being hit by a ball. Sprains, fractures, cuts, bruises, dislocations, and some concussions are acute injuries.
Overuse injuries develop over time. They can happen when a body part receives more repeated stress than it can recover from. Examples include shin pain from repeated running, shoulder pain from too much throwing, or knee pain that gradually becomes worse. Overuse injuries are especially important in growing athletes because training, competition, school, sleep, and growth all affect recovery.
Pain that keeps returning, swelling, weakness, reduced movement, or a drop in performance can be a warning sign. Playing through repeated pain can make some injuries worse. Tell a coach, parent, teacher, athletic trainer, school nurse, or another responsible adult.
Sprains, Strains, and Fractures
A sprain affects a ligament, which connects one bone to another at a joint. An ankle sprain often happens when the foot rolls and the ankle ligaments are stretched beyond their usual range.
A strain affects a muscle or tendon. Tendons connect muscles to bones. Strains can happen during sprinting, jumping, throwing, or lifting, especially when the muscles are tired or the movement is sudden.
A fracture is a broken bone. A fracture can result from a fall, collision, direct blow, or repeated stress. You cannot always tell a fracture from a severe sprain just by looking, so serious pain, deformity, inability to use the body part, or major swelling should be checked by an adult and a healthcare professional.
The ankle contains several ligaments that help stabilize the joint. This is one reason balance, strength, controlled landings, and suitable footwear can matter in sports that involve running and quick changes of direction.
Concussion and Head Injury
A concussion is a type of traumatic brain injury caused by a bump, blow, or jolt to the head, or by a hit to the body that makes the head and brain move rapidly. A person does not need to lose consciousness to have a concussion.
Possible signs and symptoms include headache, dizziness, balance problems, confusion, feeling slowed down, trouble remembering, nausea, vision problems, unusual tiredness, or sensitivity to light or noise. Symptoms can appear right away or later.
If a concussion is suspected, the athlete should be removed from sport immediately, should not return to play that same day, and should be evaluated according to local medical and school procedures. A healthcare professional decides when return to sport is safe.
This CDC HEADS UP video explains signs and symptoms that adults and athletes should recognize.
This Boston Children’s Hospital video explains how concussions can happen and why recognizing symptoms matters.
Why Injuries Happen
Sports injuries usually have more than one cause. Risk can increase when an athlete is tired, training changes too quickly, technique is poor, the playing area is unsafe, protective equipment does not fit, or pain is ignored. Previous injuries can also matter because a body part may need time and rehabilitation before it is ready for full sport again.
Risk is not the same as certainty. A risk factor makes an injury more likely, but it does not guarantee that an injury will happen. Prevention means reducing avoidable risks while accepting that no sport can be completely risk-free.
Training Load and Recovery
Training load means the total amount and difficulty of physical work your body has to handle. Duration, intensity, number of practices, competitions, extra workouts, and repeated movements all contribute to load.
The body becomes stronger when training is followed by enough recovery. If activity increases too quickly or the same tissues are stressed again and again without recovery, the risk of overuse problems can rise. Young athletes should have rest, sleep, varied movement, and sensible progressions in training rather than sudden jumps in workload.
Growth and Changing Bodies
During adolescence, bones, muscles, tendons, coordination, and body proportions can change quickly. A movement that felt easy a few months ago may temporarily feel different during a growth spurt. Good coaching, gradual skill progression, and attention to pain help athletes adapt safely.
Prevention Strategies
Warm Up Dynamically
A warm-up prepares the body and mind for the movements that are coming. A useful warm-up usually begins with easy movement, becomes gradually more active, and includes sport-specific actions. Examples include light jogging, skipping, side steps, controlled lunges, arm circles, gentle changes of direction, and practice movements.
A warm-up should not leave you exhausted. It should help you feel ready, alert, and able to move with control.
This Nemours Children’s Health video demonstrates dynamic warm-ups for young athletes.
Build Strength, Balance, and Movement Control
Strong muscles help control joints and absorb forces. Balance and coordination help athletes react to changes in speed, direction, and contact. Well-designed training can include squats, lunges, controlled jumps and landings, single-leg balance, core exercises, and sport-specific movement practice.
The quality of movement matters more than rushing through repetitions. A coach or qualified instructor can help correct technique.
This junior-high neuromuscular warm-up from the Sport Injury Prevention Research Centre shows how balance, control, and movement training can be combined in a warm-up.
Learn and Use Correct Technique
Technique is not only about performance. It can also affect safety. Examples include landing with control after a jump, keeping enough space between players, using correct tackling or checking rules where those skills are allowed, learning safe throwing mechanics, and knowing how to fall or stop safely in a particular sport.
Rules also protect athletes. Unsafe contact, dangerous play, and ignoring officials can increase injury risk.
Use Appropriate Protective Equipment
Protective equipment should match the sport, fit correctly, be in good condition, and be used as intended. Depending on the activity, equipment may include helmets, mouthguards, eye protection, shin guards, pads, footwear, or guards for specific body areas.

A helmet can reduce the risk of some serious head injuries, but there is no concussion-proof helmet. Equipment works best together with safe technique, rules, supervision, and early reporting of symptoms.
Hydrate and Manage Heat
Exercise produces heat, and sweating causes fluid loss. Hot or humid conditions can make it harder for the body to cool itself. Athletes should have access to fluids, take breaks, and follow local heat-safety rules and coach instructions.

Warning signs of heat illness can include weakness, dizziness, headache, nausea, unusual confusion, collapse, or feeling much worse than expected for the activity. If an athlete becomes confused, collapses, or appears seriously ill in the heat, treat it as an emergency: stop activity, alert an adult immediately, begin cooling as directed by trained adults, and seek emergency help.
Rest, Sleep, and Variety
Recovery is part of training. Sleep supports learning, mood, reaction time, and physical recovery. Rest days and lighter sessions give the body time to adapt.
Doing only one repeated movement all year can increase stress on the same tissues. Variety in activities can develop broader movement skills and reduce repeated loading of one body area. Young athletes should follow age-appropriate guidance from families, coaches, schools, and healthcare professionals about training volume and sport specialization.
Do Not Hide Pain
Pain is information. New sharp pain, pain that changes how you move, swelling, loss of strength, repeated pain after training, or pain that keeps returning should be reported. Hiding symptoms to stay in a game can delay treatment and may increase the chance of a more serious problem.
A strong team culture makes it normal to speak up. Teammates can help by taking reports of pain or concussion symptoms seriously.
What to Do When an Injury Happens
Stop, Protect, Report
When an injury happens, first stop the activity and move away from danger if it is safe to do so. Tell a responsible adult. Do not force a painful joint back into place, test a badly injured limb, or pressure an injured athlete to continue.
For a minor injury, trained adults may use basic first-aid measures and decide whether medical evaluation is needed. For severe pain, visible deformity, heavy bleeding, loss of feeling, inability to use a body part, breathing problems, loss of consciousness, suspected neck or spine injury, severe head-injury symptoms, or serious heat illness, emergency medical help may be needed.
Return to Sport Safely
Returning too early can increase the risk of another injury. A safe return depends on the injury and may include medical assessment, healing time, rehabilitation, restored strength and movement, sport-specific practice, and a gradual increase in activity.
After a suspected concussion, return to sport is a medical decision and should follow a step-by-step plan supervised by a healthcare professional.
A Practical Prevention Routine
A simple prevention routine can be remembered as Prepare – Practice – Protect – Pause – Report.
- Prepare: Begin with a gradual dynamic warm-up that matches the sport.
- Practice: Rehearse safe technique, balance, control, and sport-specific skills.
- Protect: Use suitable, correctly fitted equipment and check the playing area.
- Pause: Take rest and hydration breaks and allow time for sleep and recovery.
- Report: Tell an adult about pain, symptoms, unsafe conditions, or an injury.
This sports medicine warm-up video demonstrates a sequence of exercises intended to prepare athletes for activity.

Evidence of Learning
Strong evidence of learning includes accurate use of terms such as acute injury, overuse injury, sprain, strain, concussion, training load, and recovery. You should be able to connect an injury risk with a sensible prevention strategy instead of simply memorizing definitions.
Important skills include recognizing warning signs, communicating symptoms, evaluating equipment and environments, planning a dynamic warm-up, explaining why recovery matters, and using reliable health information.
Useful learning products may include a prevention poster, training diary, safety audit, interview summary, technique video, risk comparison, or team prevention plan.
Transfer is shown when you can apply the same prevention principles to a new sport, explain how the risks change, and adapt your plan without assuming that one routine fits every activity.
