Followup
Mid-year After injury
For example ACL injuries are more prevalent in those with poor strength of their hip external rotators ACL injuries are more prevalent in those with poor balance Patellofemoral pain is more prevalent in those with weak hip external rotators, flat feet, weak quadriceps (VMO) Shoulder impingement syndrome is more common in those with poor thoracic extension

Biomechanics/Technique
It is really hard to see things without slow motion but If something looks odd it probably is And needs professional assessment.

Dynamic Stretching
Dynamic stretching consists of functional exercises which use sports specific movement patterns to prepare the body for activity
Static stretching will probably reduce performance unless it is followed by dynamic activity Any form of stretching has very little relevance to sport where excessive muscle length is not required Static stretching will probably not prevent a muscle strain Static stretching is still valuable at other times if done in a sports specific way as many sports still require extreme ranges of motion Dynamic stretching has potential to increase performance and to reduce injury rates however must be done when the athlete is warm and needs to be sports specific
Performing a properly structured professionally designed warmup and competing will do the following
Performance Reduce injury rate
Is the sports specific part Which, if done correctly Is the only part you have to do
Several Programs exist that have been shown to reduce the incidence of ACL injuries from 60 -89% Focus on
Proper landing technique Engaging knee and hip flexion in landing and lateral manoeuvres Avoiding excessive dynamic valgus at the knee on landing and squatting Increasing hamstring, gluteus medius, hip abductor strength
Advanced Physiotherapy and Injury Prevention
PEP PROGRAM (74 81% reduction in ACL Injury Rates) Developed due to incidence of female ACL injuries (2-8x men) Developed by Santa Monica Orthopaedic and Sport Medicine Research Foundation. Designed to replace the traditional 20 minute soccer warmup Emphasis on soft landing and deep knee and hip flexion Optimally the program should be performed at least 2-3 times per week during the season
These programs are excellent but only cover knee injuries We know how to prevent many other running injuries So ..... Integrating what we know from these programs with what we know from running biomechanics will result in
A world class sports warm-up routine for sports requiring speed, agility and quickness designed to improve performance and reduce injury, that INTEGRATES INTO YOUR CURRENT TRAINING PROGRAM
Reduced fitness increases injury risk irrespective of experience in the sport Least fit are 14X more likely to get injured than most fit (Pope et al 2000)
Fatigue causes changes in technique (most muscle tears occur when the athlete is fatigued in AFL) The muscular contractile unit loses up to 20+ percent of its ability to withstand load when fatigued High BMI
Increases forces Effects tendon health

BMI= kg/m2 Normal 18-25 Above or below doubles the injury risk
Periodisation is the process of separating the annual or long-term training plan into smaller more manageable periods or cycles and phases.
This allows for a more effective manipulation of training variables, with the goal of optimizing the athletes physiological and psychological state of preparedness for the main competitions of the year while avoiding injury or the over-trained state. (Dolcetti 2000, adopted
from Bompa, 1983)
Fair play means respecting the opposition, the officials and the rules, staying calm no matter what happens, and maintaining your dignity whether or not you are winning. Some rules are designed and enforced to reduce or remove the risk of injury. For example, hockey players arent allowed to raise their sticks above shoulder level, spear tackling in rugby is illegal, and physical contact in non-contact sports is penalised. This is the responsibility of coaches, player and officials

Bracing and taping. Bracing and taping can provide some protection against injury to joints. Bracing vs Taping.
Footware. Players wearing shoes with air cells in the heel were 4.3 times more likely to injure an ankle than those wearing shoes without air cells Br J Sports Med 2001;35:103-108

Equipment
Make sure you have a system of monitoring and reporting both potential and current hazards. Make individuals responsible for checking areas or equipment regularly. Emergency procedures Ensure: a qualified first-aider is always at training and competition a first aid kit is always available and is well sign-posted emergency access is always clear, and that coaches know the directions to the nearest Accident and Emergency (A&E) clinic a phone is always available, to contact emergency services. Note: Ensure that any visiting teams know the emergency procedures at your venue.
