  Sand Dune Training

            By Andrea Flagg
Background to Subject
• Sand dune running is a common training method
  often used in the conditioning phase of a program.
• Popularised by Percy Cerutti and Herb Elliot.
• Have been used by many amateur and professional
  sporting teams during pre-season
  training.
• Aerobic interval training


                                      Herb Elliot following his coach
                                               Percy Cerutti
Importance to Study
• Studies of past performances claimed to have
  been enhanced by this method of training.
• The physiological and psychological benefits of
  sand dune training is a vital component to
  both a coach and the athlete in order to gain
  maximum benefits.
Critical Evaluation of Research
• A study by Pinnington and Lloyd was
  conducted of seven sprint based athletes.
• The study investigated the difference
  between the effects on lower limb kinematics
  and running speed of maximal effort running
  on sand dunes compared to running on a
  grass hill of similar gradient.
Critical Evaluation Cont.
• Data displayed that running on sand is much more
  demanding than grass, causing a lowering of running
  velocity.
• Ground contact time is significantly greater and stride
  rate is significantly reduced when running on sand.
• The study proves this with average stride length values
  of 1.77m and 2.67m for sand and grass respectively.
• Sand dune running causes reductions in running speed,
  stride rate, stride length and thigh range of motion,
  proving that the body has to work significantly harder
  to complete a hill sprint on sand
Practical Applications
Example of sand dune sessions:
Various repetitions can be applied to a number athletes
   by adjusting the distances:
• 8 to 10 repetitions over 40 metres (jumpers and
   throwers)
• 8 to 10 repetitions over 50 metres (sprinters and
   hurdlers)
• 8 to 10 repetitions over 150 metres (middle distance
   athletes)
• 8 to 10 repetitions over 200 metres (long distance
   athletes)
Practical Applications
• Sand dune training helps improve an athlete’s
  running technique
• Teaches an aggressive arm & shoulder action.
• Safety Barrier
• Neuromuscular Benefits- Stride Length & Stride
  Frequency.
• Metabolic Benefits-Aerobic VO2 Max &Energy
  Costs
• Improves Anaerobic Lactate Threshold .
• Mental Preparation
AFL Giants Sand Dune Training
• This video is short clip by the Giants AFL club,
  demonstrating the physical and mental
  exhaustion that is experienced in a sand dune
  training session
• To watch minimise screen view and right click
  the black box then click ‘preview’.
Further Research
• There is little scientific literature that explains
  the role that sand hill running may play in
  training for power events.
• Running on flat soft sand is 1.4 times more
  energy demanding than running off other flat
  surfaces such as grass.

                          vs
Conclusions
• Numerous of benefits of sand dune training
  for athletes requiring speed, strength and
  endurance.
• Improves overall running economy.
• Less stress on joints.
• Increases the resistance of muscles to fatigue.
• Benefits for power training are yet to be
  scientifically proven.
