View source for Rib stress fracture in rowers

=== Technique ===
Technique needs to be continuously fine-tuned. Often, small flaws in technique can be a cause or related to the of stress fractures. Some examples of most occurring technique faults: 
# Bent arms: this occurs when the rower starts the leg drive by pulling their arms rather than pushing with both legs resulting in an increase of lactic acid in the arms and reduce of the oxygen supply 
# High pull: this occurs when the rower pulls the oar too high during the pull phase which results in their back leaning too far back and a higher energy consumption 
# Bending backwards too early: this occurs when the rower starts to lean back too early in the drive phase instead of driving back with his legs resulting in a weaker movement 
# Over-reaching: this occurs when the rower comes back in and stretches too far forwards pushing their shins passed the vertical position. This results in a weak starting position for the following drive phase, increasing the injury risk.    
Rowers need good basic aerobic condition, mobility and flexibility of the trunk, arms and legs, and physical strength, speed and endurance.  In general, the training programme consists for 60 to 70% of aerobic training and 30 to 40% anaerobic training.
