Sports injuries
- There are 3.7 million sport and exercise related injuries each year. 1/3 needs medical
treatment. In reality the number is a lot higher since a lot of overuse/chronic injuries
are unreported.
- Predispositions + external factors  susceptible athlete + event  injurie




- Sudden cardiac arrest is a very uncommon event that can happen during sport
participation.
o <35 years: mostly because of congenital abnormalities of the heart that can
cause heart muscle diseases like hypertrophic cardiomyopathy (thickening of
the heart muscle)
o >35 years: mostly because of coronary artery disease  blockages of the
arteries (caused by cholesterol)

, Sport & Health

o Screening:
 Medical history, symptoms, risk factors, glucose/cholesterol levels,
physical examination, ECG, exercise testing (combined with ECG)
 ECG in athletes is often abnormal because of the high amounts
of exercise. This doesn’t directly mean that there is a heart
problem
 Spiro-ergometry
 To measure heart, lungs and muscles during exercise
 Ventilatory threshold (VO2max)
o Normal: 40-50 ml/kg/min
o Athlete: 70-80 ml/kg/min
o Pathologic: 15-20 ml/kg/min
o The outcome (whether you are prone to be an athlete) is
influenced (70%) by your genes
- Acute injuries are often caused by atraumatic event such as a fall or a hit. They need
immediate medical treatment. Damage is often found in the:
o Bones (fractures)
o Cartilage
o Ligaments
 Traumatic ankle injury
 Rupture of the ligaments
 39% still has symptoms after 6.5 years
 Can cause cartilage damage
 Unhappy triad: ACL rupture + medial collateral ligament rupture +
meniscus rupture
o Muscles
o Tendons
- Chronic/overuse injuries are caused by repetitive
microtrauma to the tissue. It is often difficult to
treat and prevent these injuries.
o Usually there is a homeostasis in load and
loading capacity. The right training causes
an improvement of loading capacity and
therefor the amount of load/performance.
Loading capacity depends on:
 Intrinsic factors
 Anthropometric factors: gender,
weight, leg differences, x-/o-
knees, flat foot, high arched foot
 Age
 Psychological status
 Extrinsic factors
