Dean et al (2005) showed that subjects improved both 40 yard
time and shuttle times after an 8 week hip flexion resistance training program. There were no improvements in the control
group. Results were published by the
Journal of Strength and Conditioning.
A simple hip flexion exercise is lying leg raises. Make sure your lumbar spine stays flat against
the floor when performing this exercises.
A more advance exercise is hanging leg raises. These exercises will challenge your core
along with the hip flexor group.
In summary, everyone should follow a total body, all joint
action, exercise routine. If you are
missing a few joint actions in your weekly routine, you may be shorting
yourself athletic improvement or even worse, creating muscular problems that
may lead to injury down the road.
