1
Defining injury in sport is a significant challenge, mainly due to its subjective nature.
2
You see, what may appear as an injury to one person might not seem the same to another.
3
One athlete might still be able to function quite well despite feeling some pain, while another might find it impossible to play even with slight discomfort.
4
This creates all sorts of problems for research and by extension the practice of sports medicine.
5
Because if we don't know how to define an injury, figuring out its impact or how to develop a rehabilitation or prevention program is next to impossible.
6
Add to that the tendency for injuries to have profound psychological aspects too,
7
like stress or pressure, which can significantly hamper an athlete's performance.
8
Thanks.
9
And then there are the various types of physical injuries, from simple sprains and strains to more severe cases like fractures or concussions.
10
The upshot of all of this is that defining injury is really hard.
11
So in this lecture we're going to delve into how sports injuries are defined, what they are and how they occur, and their effects.
12
When we refer to sports injuries, we are talking about injuries that occur during sporting activities or exercise.
13
At its most basic, in research literature,
14
an injury is defined as tissue damage or other derangement of normal physical function due to participation in sports,
15
resulting from rapid or repetitive transfer of kinetic energy.
16
Injuries can occur as a result of an acute traumatic event like a collision or a fall, or as a result of repetitive stress.
17
That definition is a good start, but it doesn't really tell us anything practical about the tissues involved
18
or the severity of the injury or how long recovery will take.
19
To make things more pragmatic, let's look at defining injury through a couple of different lenses.
20
The first lens involves classifying injuries according to what kind of tissues they affect.
21
Fundamentally, injuries affect at least one of the four classifications of human tissue: nervous, epithelial, muscle or connective.
22
This means that injury will involve damage to one of these tissues, specifically interfering with physical function and subsequently participation in sport.
23
For example, nervous tissue damage could lead to numbness or weakness, such as nerve impingement from a herniated disc.
24
Epithelial tissue may be damaged in injuries like skin abrasions.
25
Muscle tissue injuries are probably the most widely recognised classification of injury in sport, and include things like strains and tears.
26
Connective tissue, which includes ligaments and tendons, are the culprits in sprains and tendinopathies.
27
Thank you.
28
The next of our defining injury lenses centres around the nature of their onset.
29
Do they come on suddenly, after a collision, or perhaps the injury is a little more pernicious, developing slowly over time?
30
There are generally considered to be three main types of injury onsets.
31
acute injuries, sudden onset repetitive injuries, and gradual onset repetitive injuries.
32
An acute injury happens after a sudden trauma and usually hurts straight away.
33
Examples of acute injuries include ligament sprains, bone fractures and joint dislocations.
34
These occur due to a specific and identifiable event usually involving a high force impact or unusual movement, a fall, a tackle or some kind of collision.
35
On the other hand, repetitive injuries can be broken down into those with sudden onset and those with gradual onset.
36
Repetitive injuries with sudden onset can happen when an individual performs an activity they are not conditioned for, leading to unexpected trauma.
37
These injuries often feel like acute injuries, but they are actually caused by repetitive stress over time.
38
Thank you.
39
The next important lens gives some context to our definition of injury because context is key in defining sports injuries.
40
The type of sport, the level of competition and the position played can all influence the nature of the injury.
41
acute injuries while overuse or poor technique can result in gradual onset injuries.
42
Environmental factors such as playing on a hard surface can also contribute to injury risk.
43
To simplify matters, think about it through a sequence lens, starting with physical complaints, the potential need for medical attention, and then the amount of time loss incurred.
44
Some injuries will have all three of these characteristics, whereas others will only have one or two.
45
All injuries tend to start with a physical complaint, the discomfort or abnormal feeling experienced by the athlete.
46
You might feel knee pain after running, but it may not interfere with your regular activities and you may not seek medical attention for it.
47
If you perceive the physical complaint as being significant, you may seek medical attention.
48
This could be something like a muscle strain where you pursue professional, medically informed treatment to aid your recovery, but it might not necessarily mean you miss any games or training.
49
The third in the sequence are injuries that lead to time loss, where you can't play your chosen sport.
50
And this is usually, but not always, associated with the last step in the sequence where you sought out medical attention.
51
An example might be an anterior cruciate ligament or ACL tear
52
which needs surgery and a considerable amount of time away from sport for rehabilitation.
53
This raises an important point about the importance of defining injury through another lens that of severity.
54
The sequence I talked about, which starts with the physical complaint, feeds into seeking medical attention and culminates in time loss.
55
That can be used to give an idea of how severe the injury is.
56
Severity is determined by several parameters including the type and extent of tissue damage,
57
the effect on the athlete's ability to participate in their sport and the duration of recovery.
58
Practically speaking, minor injuries typically don't cause significant disability or time loss.
59
Moderate injuries might limit athletic performance and require a recovery period, but they don't lead to permanent disability.
60
And severe injuries could cause significant disability.
61
They might require surgical intervention or lead to substantial or even permanent period away from the sport.
62
That rounds out our definition of injury, what tissues they affect, the nature of their onset and their severity,
63
both in terms of physical complaints and the need to seek medical attention or take time off to recover.
64
We also talked about the importance of context, how the causative factors can be markedly different based on the athlete's physical characteristics and the sport they are participating in,
65
or their environment.
66
That raises another important aspect of defining and understanding injuries in sport.
67
We always need to consider the risk factors for injury.
68
In reality, lots of variables exist and can interact to become risk factors for the development of an injury.
69
In injury epidemiology research, risk factors are typically classified as being intrinsic or extrinsic.
70
Intrinsic factors originate within the body.
71
Things like your age, your sex, your body size, your fitness level, or whether you have a previous injury history.
72
Intrinsic risk factors are usually further stratified into non -modifiable things that you can't change, like your age, and modifiable like your body mass index.
73
For example, younger athletes might be more prone to growth -related injuries like Osgold -Schlatter disease,
74
While older athletes might have a higher risk of degenerative injuries like tendinopathy, Here, age is the non -modifiable entrance or risk factor.
75
Your fitness level can also contribute to injury risk.
76
If you are stronger or more aerobically fit, this tends to lower your injury risk in most sports.
77
Here, fitness level is a modifiable intrinsic risk factor
78
because an athlete can always undertake a training regimen to get stronger or faster or even fitter.
79
Extrinsic risk factors, on the other hand, are external to the athlete.
80
These include factors like the type of sport, the equipment being used, the playing surface, or the weather conditions.
81
For instance, contact sports like rugby have a higher injury risk than non -contact sports like swimming.
82
Equipment can play a role too.
83
Improper footwear might increase the risk of foot and ankle injuries, or the plank surface might impact injury risk too.
84
For example, some research has shown
85
that certain athletes playing on artificial grass surfaces have a higher
86
risk of foot injuries compared with those playing on natural grass surfaces.
87
Taken together, the mechanisms of injury in sport are diverse and can depend on a combination of both intrinsic and extrinsic factors.
88
For example, in football, a player might suffer a sprain or fracture from a tackle, the tackle being an extrinsic risk factor to do with the sport involved.
89
However, if the player had a prior history of ankle sprains, which is an intrinsic risk factor, they would be at a higher risk of suffering another sprain.
90
In contrast, a tennis player might develop tennis elbow, a type of tendinopathy, from the repetitive action of swinging their racket.
91
The mechanism of injury here is overuse, which is an extrinsic factor.
92
However, the risk could be increased by poor technique or inappropriate equipment.
93
The important piece to note here is that Risk factors can interact.
94
A rugby player with a high body mass index, an intrinsic risk factor, playing in wet slippery conditions, an extrinsic risk factor, might be at a greater risk of knee injuries.
95
The bottom line here is that defining injury in sport isn't as straightforward as it first seems.
96
We can't pin it down to a single definition because it varies greatly depending on who's experiencing it, what sport they're playing, how they're playing it,
97
and a whole host of other factors.
98
It's important to keep in mind that injury doesn't just mean physical damage.
99
It can also have profound psychological effects.
100
And it's not just about the present moment either, it's also about what happens afterward.
101
What's the recovery like?
102
How does it affect the athlete's performance?
103
How does it change their approach to the sport?
104
These are all questions that need to be answered to truly understand the impact of injury.
