Injury prevention in sport: HSC PDHPE Sports Medicine

Legacy syllabus. This page covers the former PDHPE Stage 6 syllabus (listed by NESA as PDHPE Stage 6 (2012)). The last PDHPE HSC exam was held in 2025. From the 2026 HSC, students sit Health and Movement Science 11-12 (2023) instead: see our HSC Health and Movement Science hub. Use this page only as background or for older revision material.

The single most cost-effective intervention in sport is preventing injury rather than treating it. The syllabus expects you to know the categories of prevention strategy and to be able to apply them to specific sports and athletes.

Pre-screening

Pre-screening is the medical assessment of an athlete before they start (or return to) sport. The purpose is to identify pre-existing conditions, previous injuries, and risk factors before they become problems.

For school-age athletes, basic medical history at the start of the school year, immunisation status, and parental consent for activities are standard.

For competitive adult athletes, pre-season medical screening typically includes:

• Medical history including previous injuries.
• Cardiovascular screening (especially relevant after cases like the Marc-Vivien Foe and Fabrice Muamba cardiac arrests in elite football).
• Musculoskeletal screening (asymmetries, residual injury, range of motion).
• Blood tests where relevant (iron, vitamin D).
• Dental, vision, and hearing checks for specific sports.

For older returning athletes, screening is particularly important. Recreational athletes returning to sport after years of inactivity have higher rates of cardiac events and overuse injuries than continuous trainers.

Skill and technique

Many injuries are technique injuries. Poor technique loads tissues in ways they cannot tolerate, especially over repeated exposures.

Examples:

• ACL injuries are dramatically reduced by training proper landing technique (knees over toes, soft landing, not letting the knee collapse inward).
• Overuse running injuries are reduced by addressing gait issues (overstriding, excessive heel-strike on hard surfaces, weak hip stabilisers).
• Throwing injuries in cricket and baseball are reduced by proper biomechanics, age-appropriate pitch limits, and rotation between bowling spells.
• Tackling injuries in football codes are reduced by trained tackle technique, particularly head positioning.

Technique-based prevention requires qualified coaching. Programs like the FIFA 11+ injury prevention warm-up, ACL injury prevention programs in netball, and concussion-reduction tackling drills are documented evidence-based interventions.

Physical fitness

A well-conditioned athlete has lower injury rates than an unconditioned one. The fitness components matter individually.

• Strength. Strong muscles protect joints. Specifically:
  • Strong quadriceps and hamstrings protect the knee.
  • Strong core protects the spine.
  • Strong hip stabilisers protect the lower limb.
  • Strong neck protects against whiplash and concussion.
• Endurance. Fatigued athletes have higher injury rates than rested ones. End-of-game injury rates in team sport are documented to be substantially higher than first-half rates.
• Flexibility. Adequate range of motion reduces strain on muscles and tendons. Excess flexibility, in some sports, can increase injury risk by reducing joint stability.
• Speed and agility training. Builds the neuromuscular control needed to handle the rapid direction changes that cause many ACL and ankle injuries.

The principle: train for the demand of the sport.

Warm-up and cool-down

Already covered in detail in Core 2 principles of training. For injury prevention specifically:

Warm-up progressively raises tissue temperature (warm muscles tear less than cold muscles), increases joint range of motion, primes the cardiovascular system, and activates the nervous system. Standard 10-15 minutes of general aerobic activity, dynamic stretching, and sport-specific movement.

Cool-down supports recovery and reduces post-exercise soreness. Standard 5-10 minutes of light activity followed by static stretching.

The FIFA 11+, a 20-minute structured warm-up program, has been shown in randomised trials to reduce injury rates in amateur soccer by 30-50%. It is the canonical evidence-based example of warm-up as prevention.

Taping and bandaging

Strapping the joint with sports tape or a brace before competition or training.

Most common uses:

• Ankle taping to support the lateral ligaments after previous sprain. Strong evidence of reduced re-injury rates.
• Wrist taping in gymnastics and rugby league for joint support.
• Patellar taping for patellofemoral pain syndrome (knee tracking issues).
• Shoulder taping in throwing sports.

Taping limits range of motion at the end ranges (where injury occurs) while preserving functional range. Done well it provides mechanical support and proprioceptive feedback. Done poorly it gives a false sense of security without doing much.

Bracing (using rigid or semi-rigid braces rather than tape) is used for similar purposes, particularly after ligament surgery (ACL braces post-surgery) and chronic instability.

Protective equipment

Sport-specific equipment is mandatory or strongly recommended depending on code:

• Mouthguards in football codes, hockey, boxing, martial arts. Substantially reduce dental injuries and may modestly reduce concussion (the science is debated).
• Helmets in cycling, cricket batting, ice hockey, skateboarding, motorsport. Reduce skull fractures and traumatic brain injury, though do not eliminate concussion.
• Shin pads in soccer, hockey.
• Wrist guards in skateboarding, snowboarding.
• Eyewear in racquet sports (squash, badminton).
• Body padding in cricket batting, motorcross, ice hockey, gridiron.

Australian Standards (AS) govern much of this equipment. Wearing equipment that does not meet standards (cheap helmets, non-compliant mouthguards) provides false confidence.

Environmental considerations

Heat, cold, altitude, weather, and air quality all affect injury and illness risk.

Heat

Sport Australia's hot weather guidelines use wet-bulb globe temperature to set play/no-play thresholds. Heat illness ranges from minor (heat cramps) to severe (heat exhaustion, heat stroke). Heat stroke is a medical emergency.

Prevention:

• Modify or cancel play in extreme heat.
• Schedule sport for cooler times of day.
• Hydration breaks every 15-20 minutes.
• Acclimatisation before competition in hot environments.

Cold

Hypothermia is less common but a real risk in outdoor winter sport, water sport, and altitude. Prevention includes appropriate clothing, dry kit, and shelter access.

Air quality

Bushfire smoke and other air pollution affect sport. Sport Australia and state agencies issue guidance during smoke events. Outdoor sport during high pollution exposes athletes to respiratory irritation and longer-term lung damage.

Surface

Playing surface (turf, grass, court, beach, road) affects injury patterns. Hard surfaces increase stress fracture and joint impact risk; uneven surfaces increase ankle injury risk.

Hydration and nutrition

Already covered in detail in Core 2 nutrition. For injury prevention specifically:

• Dehydration impairs performance and increases injury risk. Athletes losing more than 2% body weight in fluid are at higher risk for soft tissue injury, heat illness, and judgment errors.
• Energy deficiency (eating too little for training load) increases stress fracture risk and impairs immune function.
• Calcium and vitamin D support bone health. Deficiency increases stress fracture risk.
• Iron for endurance athletes, especially females. Iron deficiency impairs performance and recovery.

How prevention compounds

The strongest injury prevention is the layered version: pre-screening identifies risk; coaching addresses technique; conditioning builds resilience; warm-up primes the body; taping protects specific vulnerable joints; equipment provides additional protection; environmental management avoids extreme conditions; nutrition supports recovery.

Single-strategy prevention (only wearing a mouthguard, only doing warm-ups) is less effective than the integrated approach. HSC extended responses on injury prevention should recognise this.
