Major Injuries in Road Running

Incidence rate of running injury is common, but the number vary

• 18.2% to 95%
• 6.8-59 injuries per 1000 hours of running
• The rate is high in the modern cities

Most Common Injuries:

Shin Splints

• During landing and propulsion:
  Repetitive contraction of post. Tib, soleus, flexor digitorum logus generate excessive stress on tibia, causing inflammation
  
  
• Insufficient capacity of bone remodeling:
  Repetitive and persistent stress on tibia from muscle contraction and ground reaction force during landing
  
  

Tendinopathy

• Excessive loading has been considered to be the main stimulus
• Repetitive loading beyond tolerance causes tissue degeneration
• Achilles teninopathy
  Excessive loading from calf muscles predispose the development
  
  
  
• Patellar tendon
  High and excessive eccentric loads of qua. Femoris
  
  
  
• Plantar Fasciitis
  Degeneration of plantar fascia, causing pain during weight bearing, failing to support the loads
  
  
  
  With ageing or prolonged repetitive overloading, the ability of absorption of plantar fascia and fat might decrease
  
  
  

Patellofemoral Syndrome

• Injury Mechanism
  Abnormal patella tracking with high compressive loading from quad. on patellofemoral joint
