muscle involved : rowing vs skiing

[carlb]

ExRx.net added an entry in Cardio for the Ski Ergometer
http://exrx.net/Aerobic/Exercises/SkiErgometer.html

Seems incorrect for "Bearing" to be "Non-weight".

SkiErg Force (Articulation)
Dynamic (The contractions of a muscle resulting in movement.)
Hip: Extension, and Flexion
Knee: Extension
Ankle: Plantar Flexion
Shoulder: Extension
Scapula: Retraction, and Downward Rotation
Elbow: Extension
Spine: Flexion, and Extension

So they have Hips and Spine working on drive and recovery.
Comments say "Staggered stance places more emphais on obliques."


The C2 Rower http://exrx.net/Aerobic/Exercises/RowErgometer.html has alwasy been listed

Rower Force (Articulation)
Dynamic
Hip: Extension
Knee: Extension
Ankle: Plantar Flexion
Shoulder: Extension
Scapula: Retraction
Elbow: Flexion

Static (aka Isometric, The contraction of a muscle without significant movement)
Spine: Extension


Comparing to Rower on ExRx SkiErg works the Hip a 2nd way Flexion; Knee and Ankle the same. They list the Shoulder on both as Extension, but IMO the Skierg works it thru a much larger range. Scpula a 2nd way Downward Rotation. Elbow is opposite, extended on Skier. Spine on Skierg is worked both Flexion and Extension with Dynamic movement, on the rower the spine is worked "static extension" i.e. not moved.

On the skier I think the Spine Flexion does much more work pulling against the flywheel, I think the extension is against gravity and much easier. So skier seems a good complement to the rower where the rower Extension is pulling against the flywheel.

I think the Hip is similar. On the skierg Hip Flexion (closing) working hardest pulling against the flywheel, extension lifts body weight against gravity and seems easier. The rower does Hip Extension working hard against the flywheel, so again complements the skier.

Also applicable is the exercise "Cable Standing Overhead Crunch" that has a movement that is part of the SkiErg motion:
http://exrx.net/WeightExercises/RectusA ... runch.html

Unlike the motion on the SkiErg in the standing crunch the legs (knees) and hips remain at a fixed angle.

Target is Rectus Abdominis
Synergists (assists another muscle ) are Obliques

Stabilizers (A muscle that contracts with no significant movement to maintain a posture or fixate a joint):
Iliopsoas
Tensor Fasciae Latae
Rectus Femoris
Sartorius
Latissimus Dorsi
Teres Major
Deltoid, Posterior
Triceps, Long Head
Rhomboids
Trapezius, Lower
Pectoralis Major, Sternal
Pectoralis Major, Clavicular
Pectoralis Minor
Serratus Anterior

The seated cable row would be like rowing...with stiff legs

In fact i would like to know which muscle groups are involved if i practice the skierg with the same movement that the one show in the video of concept2.

I have just received my SkiErg and though I really haven't given it a proper go yet, my abs were one of the first muscle groups I noticed feeling the effect of the effort. This may have a lot to do with the fact that my abdominal muscles are particularly weak but I know I don't feel a burn in them from using the rowing machine.

With the SkiErg, our hands are above our shoulders and a significant portion of our body weight is being carried by our arms. As noted in "Anatomy Trains", (chapter 2, page 66), this engages the rectus abdominis in a way not otherwise possible. When we climb trees (or hang from a branch or a bar), the rectus abdominis functions to stabilize the pelvis.

I really like Anatomy Trains. I'd forgotten this little gem about our abdominal muscles until I reviewed this thread. I highly recommend that text to anyone interested in understanding functional movement.
