Introduction Warm-up and Stretching Running Injuries
Causes - foot mechanics, shoes, biomechanics of
Common running injuries Prevention and treatment
Important for increasing body temp., stretching ligaments
and muscles, and exciting the nervous system.
General y, a warm-up should be related to the activity
It is advised that static prolonged stretching - although
important, should be left to the end of your run in the cool-down phase.
Static prolonged stretching in a warm-up wil actual y
dampen the nervous system therefore affecting agility, speed, co-ordination and subsequent risk of injury
Therefore, it is advised to perform a “dynamic warm-up”
Although, for those less flexible, starting with some
prolonged stretching midway through the warm-up wil

Proper footwear necessary to maintain correct posture of
foot and minimize external stress - over pronation and
Over-pronation is excessive flattening of the arch through
the mid to late portion of the walking cycle
Over-pronation leads to decreased running efficiency and
increased strain on the foot, knee, hip, and back
Supination relates to a higher arch and resultant
increased load to the outside of the foot
Improper foot mechanics can be corrected via exercise,
Important to identify your foot type and use
appropriate shoes in order to minimize injury risk
Motion control - excessive over-pronators Stability - some degree of over-pronation Cushioning - supinated foot
Everyone has a different foot, make sure one of the
Foot, ankle, knee, hip, and pelvis al need to be working
properly to minimize strain and prevent injury
A fault in any of the biomechanics causes an altered
running pattern and undue stress on the surrounding
Most common biomechanical fault in the body is the
This results in over-pronation of the foot, internal twisting
of the knee and hip, and associated rotations of the
Altered biomechanics causes muscle imbalances and
Muscle imbalance is when specific muscles
differ in strength or flexibility based on their

Over time this imbalance creates wear and tear
to joints and ligaments and causes injury,

Running Injuries - Prevention and Treatment Early Warning Signs of Injury
Minor aches and pains persistent after run Soft tissue or joint swel ing Lasting tenderness on palpation days after run Loss of joint range of motion or stride
RICE - rest, ice, compress, elevation Seek professional assistance
Important to identify the cause therefore gait analysis
or biomechanical evaluation may be necessary
Here is a list of things to do for prevention:
Keep a daily log Proper sleep for tissue repair, rest from running when
Balanced diet - consult your coach or dietician to
ensure you are meeting the demands of your training
Dynamic warm-up prior to run Static stretching in cool down phase Cross training and muscle strengthening to balance
Proper footwear - consult with the experts at the
Strong glute muscles are important for
biomechanical balance of the hip and knee
During running cycle, glutes responsible for
external y rotating leg and keeping the leg
Consists of three muscles: Gluteus Maximus,
Problematic in people due to daily postures from
sitting - muscle becomes de-activated and weak
One Simple Exercise to Train the Glute Muscles:
Standing - hold arms out in front of body at shoulder level
with smal weight in hands (soup can or water bottle). Feet shoulder width apart
Slight forward tilt of pelvis, tighten core muscles. Slowly
bend at hips and lower body as if sitting into chair. Lower down far enough where proper mechanics are kept.
Ensure weight of body is through heels of feet on the way
Make sure knees are behind toes and not drifting inwards. Repeat as many as possible with good form! Feel the
Proper footwear Adequate training program and coaching Cross training and strengthening for injury
prevention (I.e. biking, swimming, wt training)
Get a Physiotherapist to assess biomechanics
and address any imbalances that may exist
